The sustainability of these Bt crops is threatened because the corn earworm/bollworm, Helicoverpa zea (Boddie), is evolving a resistance to these toxins. Using Bt sweet corn as a sentinel plant to monitor the evolution of resistance, collaborators established 146 trials in twenty-five states and five Canadian provinces during 2020–2022. The study evaluated overall changes in the phenotypic frequency of resistance (the ratio of larval densities in Bt ears relative to densities in non-Bt ears) in H. zea populations and the range of resistance allele frequencies for Cry1Ab and Vip3Aa. The results revealed a widespread resistance to Cry1Ab, Cry2Ab2, and Cry1A.105 Cry toxins, with higher numbers of larvae surviving in Bt ears than in non-Bt ears at many trial locations. Depending on assumptions about the inheritance of resistance, allele frequencies for Cry1Ab ranged from 0.465 (dominant resistance) to 0.995 (recessive resistance). Although Vip3Aa provided high control efficacy against H. zea, the results show a notable increase in ear damage and a number of surviving older larvae, particularly at southern locations. Assuming recessive resistance, the estimated resistance allele frequencies for Vip3Aa ranged from 0.115 in the Gulf states to 0.032 at more northern locations. These findings indicate that better resistance management practices are urgently needed to sustain efficacy the of corn and cotton that produce Vip3Aa.}, number={7}, journal={Insects}, publisher={MDPI AG}, author={Dively, Galen P. and Kuhar, Tom P. and Taylor, Sally V. and Doughty, Helene and Holmstrom, Kristian and Gilrein, Daniel O. and Nault, Brian A. and Ingerson-Mahar, Joseph and Huseth, Anders and Reisig, Dominic and et al.}, year={2023}, month={Jun}, pages={577} }

No-till and conservation tillage have had variable yield effects depending on crop and location, requiring long-term system-specific studies to gauge potential benefits. Yield and weather data from a 28-year tillage study in the southeastern U.S. piedmont region were analyzed to determine the effect of various conservation tillage practices on maize and soybean productivity and stability under a variety of growth conditions. Growing seasons were grouped by soil moisture and temperature during crop growth stages, and mean crop yields and yield coefficient of variation for the tillage treatments were calculated within the year clusters. Probability density estimates were also used to predict the likelihood of obtaining yields at low and high percentiles. No-till and conservation tillage increased maize yields 42–93% and no-till decreased coefficient of variation of maize yields when soil moisture was low by 10–32%, but had a less pronounced effect on soybean yields. However, the probability of reaching the 90th yield percentile was greater in no-till than conventional tillage in both maize and soybean, by 15% and 10%, respectively. Yield differentiation occurred early in the study, before there was likely substantial differentiation of soil properties from tillage treatments. Previous reports from the site have likewise indicated little differentiation in soil health between tillage systems over the life of the study. Results suggest that surface residue management may be an important driver of system performance, possibly more so than overall soil health.}, journal={Field Crops Research}, publisher={Elsevier BV}, author={Mathers, Cara and Heitman, Joshua and Huseth, Anders and Locke, Anna and Osmond, Deanna and Woodley, Alexander}, year={2023}, month={Mar}, pages={108811} }

Recent advances in the Internet of Things enable the construction of wireless sensor systems to automate these remote monitoring efforts. This paper presents the design of a modular system to serve as a research platform for outdoor sensor development and deployment. The advantages of this system include low power consumption (enabling solar charging), the use of commercially available electronic parts for lower-cost and scaled up deployments, and the flexibility to include internal electronics and external sensors, allowing novel applications. In addition to tracking environmental parameters, the modularity of this system brings the capability to measure other non-traditional elements. This capability is demonstrated with two different agri- and aquacultural field applications: tracking moth phenology and monitoring bivalve gaping. Collection of these signals in conjunction with environmental parameters could provide a holistic and context-aware data analysis. Preliminary experiments generated promising results, demonstrating the reliability of the system.

Foliar insecticide application significantly suppressed M. sorghi infestations on both the resistant and susceptible sorghum cultivars across all locations. Planting the host plant resistant cultivar (DKS37-07) significantly reduced aphid infestation across all locations. Plant damage ratings did not vary widely, but there was generally a positive association between aphid counts and observed plant damage, suggesting that increasing aphid numbers resulted in corresponding increase in plant damage. Planting a host plant resistant cultivar and foliar insecticide application generally preserved grain yield. Both sorghum hybrids supported an array of different life stages of natural enemies (predators [lady beetle larvae and adults; hoverfly larvae and lacewing larvae] and parasitoids [a braconid and aphelinid]) for both the sprayed and non-sprayed treatments. We found a strong and significant positive relationship between the natural enemies and the M. sorghi infestation.

            Overwintering success is an important determinant of arthropod populations that must be considered as climate change continues to influence the spatiotemporal population dynamics of agricultural pests. Using a long-term monitoring database and biologically relevant overwintering zones, we modeled the annual and seasonal population dynamics of a common pest,
            Helicoverpa zea
            (Boddie), based on three overwintering suitability zones throughout North America using four decades of soil temperatures: the southern range (able to persist through winter), transitional zone (uncertain overwintering survivorship), and northern limits (unable to survive winter). Our model indicates
            H. zea
            population dynamics are hierarchically structured with continental-level effects that are partitioned into three geographic zones. Seasonal populations were initially detected in the southern range, where they experienced multiple large population peaks. All three zones experienced a final peak between late July (southern range) and mid-August to mid-September (transitional zone and northern limits). The southern range expanded by 3% since 1981 and is projected to increase by twofold by 2099 but the areas of other zones are expected to decrease in the future. These changes suggest larger populations may persist at higher latitudes in the future due to reduced low-temperature lethal events during winter. Because
            H. zea
            is a highly migratory pest, predicting when populations accumulate in one region can inform synchronous or lagged population development in other regions. We show the value of combining long-term datasets, remotely sensed data, and laboratory findings to inform forecasting of insect pests.

Strategies to address these challenges are expected to involve a redesign of agricultural production systems to increase productivity and sustainability (1, 2). Notably, changing how cropland is structured within agroecosystems is one redesign opportunity that could have multiple sustainability benefits. Agroecosystems are a complex arrangement of crop and noncrop habitats that support a diverse array of arthropods relevant to sustainable crop production, including pests, natural enemies, and pollinators. Farmers and ecologists have long known that the arrangement and abundance of crops have local impacts on pest infestations, leading to the idea that manipulation of cropland structure could alleviate pressure by pests, promote biological control, and reduce pesticide use (3–7). One aspect of this is that concentrated crop production, either size of fields planted to a single crop or prevalence of a single crop in the landscape, will result in more pest problems. Rosenheim et al. (8), in PNAS, tested this concept using a large, multicrop dataset collected from different agricultural systems to investigate whether the size of fields planted to a single crop or the amount of a crop in the surrounding landscape is positively related to pest abundance. Their key finding is the absence of a consistent relationship between pest abundance and the area of host crop at either the field or the landscape scale. They found negative, neutral, and positive relationships, suggesting that pests vary in their response to crop abundance at both the field and landscape scales (Fig. 1). The results provide a compelling argument that the relationship between pest pressure and the extent of host crop production is context dependent. This suggests that predicting the effect of crop abundance on the intensity of pest problems will require accounting for the ways in which individual pest species interact with their habitats, as well as the effects of landscape composition and configuration on their natural enemies. The results are important not only because of their relevance to the sustainable intensification of agricultural production systems but also because there has been a longstanding acceptance in the agroecological literature that increasing field size in agricultural monocultures is positively related to pest infestation levels, crop loss, and pesticide use (3, 5, 7, 9). The conceptual framework underlying this putative relationship is based largely on two ecological concepts: the resource concentration hypothesis and the natural enemies hypothesis (10, 11). The former predicts that population densities of specialist herbivores will be higher in large monocultures of their host plants than in diverse stands. The latter suggests reduced biological control of herbivores in large pure stands because these monocultures do not provide suitable habitat and resources for natural enemies. However, the generalization of these concepts to agricultural systems across broad spatial scales and the idea that large-scale monocultures intensify pest problems lacks rigorous theoretical or empirical support (8). Field studies in agricultural crops, primarily involving small plots, as well as studies in natural systems and modeling studies have shown that the effects of increasing field size on pest population density can be inconsistent (12–17). Rosenheim et al. (8) took advantage of existing data compiled by independent crop advisors or farm staff during regular sampling of pest populations or crop injury to inform decisions regarding pesticide applications. The dataset comprised >20,000 field-year observations spanning Fig. 1. The size of arthropod pest populations sampled in different annual and perennial crops were related to the size of the agricultural field and the abundance of the same crop in the surrounding landscape. Results showed that different arthropod species responded positively (pest 1) or negatively (pest 3) or had no relationship at all (pest 2) to the size of agricultural fields. Species tended to have similar trends at different spatial scales of crop production.}, number={39}, journal={PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA}, author={Kennedy, George G. and Huseth, Anders S.}, year={2022}, month={Sep} }

Current M. sacchari management programs aim to control M. sacchari with insecticides while minimizing impacts on natural enemies that contribute to biological control of aphid populations. As a result, balancing both insecticide efficacy on the target pest and preservation of biological control agents remains an important step toward sustainable management of M. sacchari in grain sorghum. To document tradeoffs between M. sacchari control and non-target impacts, we evaluated three common aphicides (afidopyropen, flupyradifurone, and sulfoxaflor) for M. sacchari control and natural enemy safety. Treatments were paired with surfactants when recommended. Insect abundance was measured before and after foliar insecticide application using randomized complete clock design small plot studies during the 2019 and 2020 field seasons. All plots were harvested at maturity to document the relationship between in-season aphid abundance and grain yield. In this two year study, the average aphid abundance three days after insecticide application was lower in some but not all insecticidal treatments when compared to the untreated control, suggesting some insecticides had limited aphid suppression capabilities. Mean cumulative aphid days were lower in all treated plots compared to the untreated control with the exception of Sefina (afidopyropen). Twenty-eight days after foliar insecticide application, there were no differences in total natural enemy abundance in any of the treatments including the untreated control, suggesting that while M. sacchari populations were reduced by foliar insecticide treatments, the insecticides did not have clear adverse effects to natural enemy populations.}, journal={Crop Protection}, publisher={Elsevier BV}, author={Lytle, Amanda J. and Huseth, Anders S.}, year={2021}, month={Nov}, pages={105764} }

Crop production sequences influence arthropod populations in temporally unstable row crop systems. Winter wheat (Triticum aestivum L.) represents one of the earliest abundant crops in south‐eastern United States. This study aims to understand primary source habitats driving brown stink bug, Euschistus servus (Say), and tarnished plant bug, Lygus lineolaris (Palisot de Beauvois), population abundance in wheat.
To better understand these relationships, adult and nymphal densities were in wheat fields weekly from flowering through harvest in 2019 and 2020. Geospatial data were used to measure landscape composition surrounding sampled fields. We investigated the influence of landscape predictors on E. servus and L. lineolaris abundance using generalized linear mixed modelling.
Field size, proportion of agriculture, proportion of wheat area, and proportion of soybean Glycine max L.) area from the previous year in the surrounding landscape were associated with E. servus abundance in wheat. Similarly, L. lineolaris abundance was associated with proportion of wheat area and soybean area from the previous year.
These results reveal the influence of soybean area planted the previous year on insect pest densities the following spring in wheat. Further, results suggest agricultural landscapes dominated by wheat are associated with decreased pest abundance across the sampled region.

To characterize H. zea distributions in relation to land use , we used historical trapping data collected from 2008 to 2019 in North Carolina to model the spatial and temporal abundance of H. zea populations across Bt -dominated landscapes. Helicoverpa zea abundance was standardized across site-year observations, and candidate landscape composition and configuration predictors of H. zea abundance were obtained. Spatiotemporal Bayesian hierarchical models were developed to make posterior predictions of H. zea abundance from environmental covariates, and results were used to generate interpolation prediction maps to visualize H. zea abundance across the sampled region. Our results suggest inverse distance weighted (IDW) soybeans is the most important predictor of H. zea abundance through time in row crop agroecosystems in North Carolina. Soybeans in North Carolina and southeastern U.S. likely serves as a critical non- Bt refuge for delaying H. zea resistance to Bt toxins in landscapes dominated by Bt maize and cotton. Moreover, soybean abundance can be used to predict the spatial abundance of H. zea in this region. Results can be applied to understand population dynamics of H. zea in landscapes dominated by genetically engineered (GE) crops expressing Bt toxins and will enable the development of sound insect resistance management strategies of H. zea populations to GE toxins targeting noctuid pests of maize and cotton. This work will also drive future geospatial studies investigating environmental predictors of resistance evolution in arthropod pests to GE technologies in crop production systems.

Sentinel plots planted on June 17, 2019, at the Sandhills Research Station in Moore County, NC, exhibited CLRDD symptoms, and disease incidence was estimated at 75% on a 0.1-ha field. Cotton aphids (Aphis gossypii Glover), the reported vector of CLRDV (Heilsnis et al. 2020; McLaughlin et al. 2020; Michelotto and Busoli 2007), were detected on plants throughout the growing season. Samples (n = 24) were collected from sentinel plots on September 20, 2019, to test for CLRDV through reverse transcription PCR. Each sample represented five symptomatic plants collected from a single plot. Total RNA was extracted from the petiole tissue of each sample using a Qiagen RNeasy Plant Mini kit (Qiagen, Germantown, MD), following the manufacturer’s recommendations. The cDNA was synthesized using a SuperScript IV first-strand synthesis system (ThermoFisher Scientific, Waltham, MA) and amplified with CLRDV-specific PCR primers CLRDV3675F/Pol3982R (Sharman et al. 2015) targeting a 310-bp genome segment of ORF3-5. Seven CLRDV-positive samples were further amplified with two additional primer sets specifically designed to detect CLRDV: AL674F/AL1407R (Avelar et al. 2019), targeting a 733-bp portion of the ORF0-ORF1, and CLPOF/CLPOR (Cascardo et al. 2015), amplifying an 880-bp fragment spanning the ORF0. Nucleotide BLAST searches showed that the best matches for all sequences in this study were derived from CLRDV with a range of pairwise identity of 99.2 to 100% for all genome segments. From symptomatic samples (n = 14), the isolated virus was confirmed as CLRDV in several cotton varieties, including Deltapine 1646 B2XF (GenBank accessions MN958131 [ORF3-5], MN958147 [ORF0-ORF1], MN958138 [ORF0], MN958133 [ORF3-5], MN958145 [ORF0-ORF1], and MN958140 [ORF0]), Phytogen 480 W3FE (MN958134 [ORF3-5], MN958144 [ORF0-ORF1], and MN958141 [ORF0]), Stoneville 5471 GLTP (MN958135 [ORF3-5], MN958143 [ORF0-ORF1], and MN958142 [ORF0]), and Nextgen 5711 B3XF (MN958130 [ORF3-5], MN958148 [ORF0-ORF1], MN958137 [ORF0], MN958132 [ORF3-5], MN958146 [ORF0-ORF1], MN958139 [ORF0], and MN958136 [ORF3-5]). CLRDD is a newly named disease of cotton in the United States that was first reported in Alabama (Avelar et al. 2019), Georgia (Tabassum et. al. 2019), Mississippi (Aboughanem-Sabanadzovic et. al. 2019), and Texas (Alabi et al. 2020). Although the virus has been reported with variable impacts, losses can be extensive in some fields that are affected (Avelar et al. 2019). North Carolina produced over one million bales of cotton in 2019, and given reported losses among fields with high disease incidence, CLRDV has the potential to significantly reduce cotton yield and quality for the state if it becomes widespread.The author(s) declare no conflict of interest.References:Aboughanem-Sabanadzovic, N., et al. 2019.

Determining its utility in cotton pest management requires understanding its effects on F. fusca and F. occidentalis. Individual adult female F. fusca and F. occidentalis were exposed to cotyledon disks cut from greenhouse-grown cotton expressing Cry51Aa2.834_16 (MON 88702) or a near-isoline (non-Bt) with or without an imidacloprid seed treatment. Insects were exposed for 72 h and mortality evaluated. Next, individually caged seedlings were infested with five adult female F. fusca or F. occidentalis and egg numbers counted after 72 h. Larval establishment determined after 10 days for F. fusca or 7 days for F. occidentalis. Exposure to MON 88702 in the absence of the imidacloprid seed treatment caused significant adult mortality in F. occidentalis. Exposure to the imidacloprid seed treatment caused significant adult mortality in both species on both MON 88702 and non-Bt cotton plants. Oviposition and larval establishment were reduced by both MON 88702 as well as imidacloprid seed treatment in both species, but the effect size differed between species.

Although production practices have changed, changes in landscape composition and climatic conditions are also anecdotally associated with increasing populations. To better understand the recent increase in L. lineolaris infestations in Virginia cotton, 56 commercial cotton fields were sampled weekly in 2017 and 2018 for a nine-week period during the growing season. Insect density was measured using sweep net and black drop cloth sampling, targeting adult and nymphal populations, respectively. Geospatial crop production and forest disturbance data were used to measure the composition and management history of landscapes adjacent to sample fields. We also used spatial climate data sets to document the relationship between increasing L. lineolaris and temperature variation. We investigated the significance of landscape composition and climatic effects increasing L. lineolaris infestation intensity using a regression modeling approach. We found the best overall predictor of L. lineolaris abundance was higher annual minimum temperatures. Several crop components in the landscape were significant, specifically corn and double-crop winter wheat and soybeans, but these habitat patches did not explain high levels of variability. Results of this study suggest that increasing minimum temperatures will favor L. lineolaris and may translate into elevated infestation intensity and increasing dependence on insecticide inputs to manage this problematic pest of cotton. Results of this study will be important to describe short- and long-term factors driving L. lineolaris infestation risk in cotton agroecosystems.}, journal={Agriculture, Ecosystems & Environment}, publisher={Elsevier BV}, author={Dorman, Seth J. and Schürch, Roger and Huseth, Anders S. and Taylor, Sally V.}, year={2020}, month={Jun}, pages={106910} }

Small unmanned aerial systems (UAS) have emerged in recent years as a versatile remote sensing tool that can provide precisely-timed, fine-grained data for informing management responses to intra-field crop variability (e.g., nutrient status and pest damage). UAS sensors with high spectral resolution used to compute informative vegetation indices, however, are practically limited by high cost and data dimensionality. This research extends spectral analysis for remote crop monitoring to investigate the relationship between crop health and 3D canopy structure using low-cost UAS equipped with consumer-grade RGB cameras. We used flue-cured tobacco as a case study due to its known sensitivity to fertility variation and nutrient-specific symptomology. Fertilizer treatments were applied to induce plant health variability in a 0.5 ha field of flue-cured tobacco. Multi-view stereo images from three UAS surveys collected during crop development were processed into orthoimages used to compute a visible band spectral index and photogrammetric point clouds using Structure from Motion (SfM). Plant structural metrics were then computed from detailed high resolution canopy surface models (0.05 m resolution) interpolated from the photogrammetric point clouds. The UAS surveys were complimented by nutrient status measurements obtained from plant tissues. The relationships between foliar nitrogen (N), phosphorus (P), potassium (K), and boron (B) concentrations and the UAS-derived metrics were assessed using multiple linear regression. Symptoms of N and K deficiencies were well captured and differentiated by the structural metrics. The strongest relationship observed was between canopy shape and N foliar concentration (adj. r2 = 0.59, increasing to adj. r2 = 0.81 when combined with the spectral index). B foliar concentration was consistently better predicted by canopy structure with a maximum adj. r2 = 0.41 observed at the latest growth stage surveyed.

These consequences are balanced by the growing necessity to manage agricultural pests. The trade-offs have motivated research to produce inexpensive and accessible food while simultaneously improving the sustainability of agriculture from field to fork. Although decades of research inform our understanding of relationships between pests, crops, and pesticides, the general systemic drivers and patterns of crop-specific pesticide use remain unclear. Understanding fundamental ecological factors that motivate pesticide use on crops is a key knowledge gap that perpetuates this ongoing dependence on pesticides. Pearse and Rosenheim (1) study several general drivers of pest pressure and associated pesticide use in California, one of the most intensive agricultural production regions worldwide. Because of the immense crop diversity and accessible data about the pesticide inputs used on those crops, the authors are able use this complex agricultural system as a test bed to ask whether pest pressure and pesticide use on agricultural crops are related to the evolutionary distance between important crop plants and their native relatives growing in noncrop areas of California (1).

This study (1) builds on a growing body of evidence that the phylogenetic structure of plant communities can have predictable impacts on pests and diseases of plants in managed and natural systems (2⇓⇓–5). Pearse and Rosenheim examine economic crop value and evolutionary history to describe the numbers of arthropod pest and crop pathogen species affecting each crop in the study region. To do this, they investigate 93 major annual and perennial Californian crops (>600-ha average area) and link economic crop value, plant community ecology, and phylogenetic relationships to describe …

Unlike other Bt toxins targeting lepidopteran cotton pests, MON 88702 does not cause direct mortality but has an antixenotic effect that suppresses F. fusca oviposition. Previous work has shown neonicotinoid seed treated (NST) crops have similar behavioral effects on thrips. This study used non-choice and common garden experiments to examine how the presence of MON 88702 cotton and soybean (another F. fusca host) with and without NSTs might alter F. fusca infestation distributions. In a no-choice environment, significant larval establishment differences were observed, with untreated soybean plants becoming most heavily infested. In choice experiments, plants expressing MON 88702 or were neonicotinoid treated had significantly lower larval establishment. Larval density decreased as dispersal distance increased, suggesting reproductive decisions were negatively related to distance from the release point. Understanding how F. fusca responds to MON 88702 in an environment where adults can choose among multiple host plants will provide valuable context for projections regarding design of MON 88702 resistance refuges. Reduced larval establishment on NST cotton and soybean suggests that area-wide use of NSTs could reduce the number of susceptible F. fusca generated in unstructured crop refuges for MON 88702. These results also suggest that although the presence of NST MON 88702 could suppress reproduction and resistance selection, over time this benefit could erode resulting in increased larval establishment on NST cotton and soybean due to increased frequency of neonicotinoid resistant F. fusca populations.}, number={10}, journal={PLOS ONE}, publisher={Public Library of Science (PLoS)}, author={Huseth, Anders S. and D’Ambrosio, Damon A. and Kennedy, George G.}, editor={Gao, YulinEditor}, year={2020}, month={Oct}, pages={e0239910} }

In the spring, L. lineolaris populations develop on non-crop weeds surrounding cotton fields. As weeds senesce, L. lineolaris migrate into susceptible cotton at the squaring stage. Given this predictable temporal colonization pattern, scouting efforts to inform insecticide interventions may be improved with a spatiotemporally targeted sampling recommendation. Using a geospatial approach, we tracked L. lineolaris populations at 352 unique sites along transects located in commercial North Carolina cotton fields over two consecutive years. Standardized sweep samples of L. lineolaris adults and nymphs were taken at each site. To relate the abundance of L. lineolaris to the spatial structure of cotton fields, the distance of the sample from the field edge and the edge-to-area ratio of each field were analyzed using GIS. All counts were related to accumulated degree days at each sample time to document seasonal progression of L. lineolaris abundance and temporal host utilization (i.e., weeds vs. cotton). Counts were also related to spatially structured scouting recommendations used in North Carolina. Nymph counts were significantly affected by accumulated degree days and distance from field edge. Higher adult counts were found in fragmented fields with greater edge-to-area ratios. Our results show that L. lineolaris nymphs were more spatiotemporally variable than adults, thereby being more likely to affect scouting accuracy when using sweep samples alone. We found that samples closer to the field edge likely increase the probability of being over the North Carolina L. lineolaris threshold.}, journal={Crop Protection}, publisher={Elsevier BV}, author={D'Ambrosio, Damon A. and Peele, William and Hubers, Allen and Huseth, Anders S.}, year={2019}, month={Nov}, pages={104898} }

Alternative insecticides must protect seedlings while they are most vulnerable to F. fusca injury (emergence through five true leaves). In this study, we evaluated non-neonicotinoid foliar insecticide sprays currently registered for use on cotton against a neonicotinoid resistant F. fusca population. During two-seasons, we compared NSTs (imidacloprid, imidacloprid + thiodicarb, and thiamethoxam) to non-neonicotinoid foliar sprays of acephate, spinetoram, abamectin, cyantraniliprole, and cyantraniliprole + abamectin in field trials to evaluate their efficacy against a neonicotinoid resistant F. fusca population. Applications were made to both early- and full-maturity cotton varieties (Stoneville 4946GLB2 & 6448GLB2) to examine F. fusca larval establishment, plant vigor, and seed cotton yield. With the exception of abamectin, foliar insecticide treatments consistently reduced F. fusca larval numbers and minimized true leaf damage at a level equal to or greater than NSTs. Yield was not affected by insecticide treatment. Non-neonicotinoid foliar sprays have utility in managing neonicotinoid-resistant F. fusca and should be recommended to alleviate selection pressure against NSTs in cotton and unnecessary economic losses due to ineffective NST use against resistant F. fusca populations.}, journal={Crop Protection}, publisher={Elsevier BV}, author={D'Ambrosio, Damon A. and Huseth, Anders S. and Kennedy, George G.}, year={2018}, month={Nov}, pages={56–63} }

Here, we report a positive relationship between the deployment of neonicotinoid seed-dressings on multiple crops and the emergence of insecticide resistance in tobacco thrips (Frankliniella fusca), a polyphagous insect herbivore that is an important pest of seedling cotton but not soybean or maize. Using a geospatial approach, we studied the relationship between neonicotinoid resistance measured in 301 F. fusca populations to landscape-scale crop production patterns across nine states in the southeastern U.S. cotton production region, in which soybean, maize and cotton are the dominant crops. Our research linked the spatiotemporal abundance of cotton and soybean production to neonicotinoid resistance in F. fusca that is leading to a dramatic increase in insecticide use in cotton.

In-season boll damage from H. zea was highly correlated to end-of-season damaged bolls. Across North Carolina, Bt cotton fields with end-of-season bolls damaged by H. zea increased during 2016 compared to previous years. Elevated damage was coupled with an increase in field sprays targeting H. zea during 2016, but not related to an increase in H. zea abundance. Bioassay data indicated that there was a range of Cry1Ac susceptibility across the southeastern United States. Given the range of susceptibility to Cry1Ac across the southeastern United States, it is probable that resistant populations are common.

Neonicotinoid compounds are currently registered for over 140 different crop uses in the United States, with commercial growers continuing to rely heavily on neonicotinoid insecticides for the control of key insect pests through a combination of in-ground and foliar applications. In 2008, the Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP) began testing for neonicotinoids in groundwater test wells in the state, reporting detections of one or more neonicotinoids in dozens of shallow groundwater test wells. In 2011, similar detection levels were confirmed in several high-capacity overhead center-pivot irrigation systems in central Wisconsin. The current study was initiated to investigate the spatial extent and magnitude of neonicotinoid contamination in groundwater in and around areas of irrigated commercial agriculture in central Wisconsin. From 2013–2015 a total of 317 samples were collected from 91 unique high-capacity irrigation wells and tested for the presence of thiamethoxam (TMX), a neonicotinoid, using enzyme-linked immunosorbent assays. 67% of all samples were positive for TMX at a concentration above the analytical limit of quantification (0.05 μg/L) and 78% of all wells tested positive at least once. Mean detection was 0.28 μg/L, with a maximum detection of 1.67 μg/L. Five wells had at least one detection exceeding 1.00 μg/L. Furthermore, an analysis of the spatial structure of these well detects suggests that contamination profiles vary across the landscape, with differences in mean detection levels observed from landscape (25 km), to farm (5 km), to individual well (500 m) scales.

Previous studies have shown that populations of L. decemlineata have become resistant to many classes of insecticides, including the neonicotinoid insecticide, imidacloprid. Furthermore, L. decemlineata has multiple mechanisms of resistance to deal with a pesticide insult, including enhanced metabolic detoxification by cytochrome p450s and glutathione S-transferases. With recent advances in the transcriptomic analysis of imidacloprid susceptible and resistant L. decemlineata populations, it is possible to investigate the role of candidate genes involved in imidacloprid resistance. A recently annotated transcriptome analysis of L. decemlineata was obtained from select populations of L. decemlineata collected in the Central Sands potato production region, which revealed a subset of mRNA transcripts constitutively up-regulated in resistant populations. We hypothesize that a portion of the up-regulated transcripts encoding for genes within the resistant populations also encode for pesticide resistance and can be suppressed to re-establish a susceptible phenotype. In this study, a discrete set of three up-regulated targets were selected for RNA interference experiments using a resistant L. decemlineata population. Following the successful suppression of transcripts encoding for a cytochrome p450, a cuticular protein, and a glutathione synthetase protein in a select L. decemlineata population, we observed reductions in measured resistance to imidacloprid that strongly suggest these genes control essential steps in imidacloprid metabolism in these field populations.}, journal={Pesticide Biochemistry and Physiology}, publisher={Elsevier BV}, author={Clements, Justin and Schoville, Sean and Peterson, Nathan and Huseth, Anders S. and Lan, Que and Groves, Russell L.}, year={2017}, month={Jan}, pages={35–40} }

The incidence of O. nubilalis-contaminated beans has become uncommon in New York, possibly because widespread adoption of Bt field corn has suppressed populations. Snap bean fields located where Bt corn has been intensively grown in space and time may be at lower risk for O. nubilalis than fields located where Bt corn is not common. To manage O. nubilalis infestation risk, growers determine insecticide application frequency in snap bean based on pheromone-trapping information in nearby sweet corn fields; adult activity is presumed equivalent in both crops. Our goal was to determine if corn planting intensity and adult activity in sweet corn could be used to estimate O. nubilalis populations in snap bean in New York in 2014-2015. Numbers of O nubilalis adults captured in pheromone-baited traps located in snap bean fields where corn was and was not intensively grown were similar, suggesting that O. nubilalis does not respond to local levels of Bt corn in the landscape. Numbers of Ostrinia nubilalis captured in pheromone-baited traps placed by snap bean fields and proximal sweet corn fields were not related, indicating that snap bean growers should no longer make control decisions based on adult activity in sweet corn. Our results also suggest that the risk of O. nubilalis infestations in snap bean is low (∼80% of the traps caught zero moths) and insecticide applications targeting this pest should be reduced or eliminated.}, number={5}, journal={Journal of Economic Entomology}, publisher={Oxford University Press (OUP)}, author={Schmidt-Jeffris, Rebecca A. and Huseth, Anders S. and Nault, Brian A.}, year={2016}, month={Jul}, pages={2210–2214} }

Development of insecticide resistance is common in T. tabaci populations, and new strategies are needed to relax existing levels of insecticide use, but still provide protection against T. tabaci without compromising marketable onion yield. An action threshold-based insecticide program combined with or without a thrips-resistant onion cultivar was investigated as an improved approach for managing T. tabaci infestations in commercial onion fields. Regardless of cultivar type, the average number of insecticide applications needed to manage T. tabaci infestations in the action-threshold based program was 4.3, while the average number of sprays in the standard weekly program was 7.2 (a 40% reduction). The mean percent reduction in numbers of applications following the action threshold treatment in the thrips-resistant onion cultivar, ‘Advantage’, was 46.7% (range 40–50%) compared with the standard program, whereas the percentage reduction in applications in action threshold treatments in the thrips-susceptible onion cultivar, ‘Santana’, was 34.3% (range 13–50%) compared with the standard program, suggesting a benefit of the thrips-resistant cultivar. Marketable bulb yields for both ‘Advantage’ and ‘Santana’ in the action threshold-based program were nearly identical to those in the standard program, indicating that commercially acceptable bulb yields will be generated with fewer insecticide sprays following an action threshold-based program, saving money, time and benefiting the environment.}, number={4}, journal={Journal of Economic Entomology}, publisher={Oxford University Press (OUP)}, author={Nault, Brian A. and Huseth, Anders S.}, year={2016}, month={Jun}, pages={1772–1778} }

Multiple applications of pyrethroid insecticides are used to manage European corn borer, Ostrinia nubilalis Hübner, in snap bean, but new diamide insecticides may reduce application frequency. In a 2 year small-plot study, O. nubilalis control was evaluated by applying cyantraniliprole (diamide) and bifenthrin (pyrethroid) insecticides at one of three phenological stages (bud, bloom and pod formation) of snap bean development. Co-application of these insecticides with either herbicides or fungicides was also examined as a way to reduce the total number of sprays during a season.


RESULTS
Cyantraniliprole applications timed either during bloom or during pod formation controlled O. nubilalis better than similar timings of bifenthrin. Co-applications of insecticides with fungicides controlled O. nubilalis as well as insecticide applications alone. Insecticides applied either alone or with herbicides during bud stage did not control this pest.


CONCLUSION
Diamides are an alternative to pyrethroids for the management of O. nubilalis in snap bean. Adoption of diamides by snap bean growers could improve the efficiency of production by reducing the number of sprays required each season.}, number={12}, journal={Pest Management Science}, publisher={Wiley}, author={Huseth, Anders S and Groves, Russell L and Chapman, Scott A and Nault, Brian A}, year={2015}, month={Jan}, pages={1649–1656} }

We investigate if intensification of a single crop in an agroecosystem has a direct effect on insecticide resistance in a specialist insect herbivore. Using a major potato pest, Leptinotarsa decemlineata, we measured imidacloprid (neonicotinoid) resistance in populations across a spatiotemporal crop production gradient where potato production has increased in Michigan and Wisconsin, USA. We found that concurrent estimates of area and temporal frequency of potato production better described patterns of imidacloprid resistance among L. decemlineata populations than general measures of agricultural production (% cropland, landscape diversity). This study defines the effects individual crop rotation patterns can have on specialist herbivore insecticide resistance in an agroecosystem context, and how impacts of intensive production can be estimated with general estimates of insecticide use. Our results provide empirical evidence that variation in the intensity of neonicotinoid-treated potato in an agricultural landscape can have unequal impacts on L. decemlineata insecticide insensitivity, a process that can lead to resistance and locally intensive insecticide use.

Recent detections of neonicotinoids in groundwater have generated questions about the sources of these contaminants and the relative contribution from commodities in U.S. agriculture. Delivery of neonicotinoids to crops typically occurs as a seed or in-furrow treatment to manage early season insect herbivores. Applied in this way, these insecticides become systemically mobile in the plant and provide control of key pest species. An outcome of this project links these soil insecticide application strategies in crop plants with neonicotinoid contamination of water leaching from the application zone. In 2011 and 2012, our objectives were to document the temporal patterns of neonicotinoid leachate below the planting furrow following common insecticide delivery methods in potato. Leaching loss of thiamethoxam from potato was measured using pan lysimeters from three at-plant treatments and one foliar application treatment. Insecticide concentration in leachate was assessed for six consecutive months using liquid chromatography-tandem mass spectrometry. Findings from this study suggest leaching of neonicotinoids from potato may be greater following crop harvest in comparison to other times during the growing season. Furthermore, this study documented recycling of neonicotinoid insecticides from contaminated groundwater back onto the crop via high capacity irrigation wells.

 Potential decreases in crop yield from reductions in bee-mediated pollination services threaten food production demands of a growing population. Many fruit and vegetable growers supplement their fields with bee colonies during crop bloom. The extent to which crop production requires supplementary pollination services beyond those provided by wild bees is not well documented. Pumpkin, Cucurbita pepo L., requires bee-mediated pollination for fruit development. Previous research identified the common eastern bumble bee, Bombus impatiens (Cresson), as the most efficient pumpkin pollinator. Two concomitant studies were conducted to examine pollination deficits in NewYork pumpkin fields from 2011 to 2013. In the first study, fruit weight, seed set, and B. impatiens visits to pumpkin flowers were compared across fields supplemented with B. impatiens colonies at a recommended stocking density of five colonies per hectare, a high density of 15 colonies per hectare, or not supplemented with bees. In the second study, fruit weight and seed set of pumpkins that received supplemental pollen through hand-pollination were compared with those that were openpollinated by wild bees. Results indicated that supplementing pumpkin fields with B. impatiens colonies, regardless of stocking density, did not increase fruit weight, seed set, or B. impatiens visits to pumpkin flowers. Fruit weight and seed set did not differ between hand- and open-pollinated treatments. In general, we conclude that pumpkin production in central New York is not limited by inadequate pollination services provided by wild bees and that on average, supplementation with B. impatiens colonies did not improve pumpkin yield.}, number={5}, journal={Environmental Entomology}, publisher={Oxford University Press (OUP)}, author={Petersen, J.

The relative ease of applying neonicotinoids at planting coupled with inexpensive, generic neonicotinoid formulations has reduced the incentive for potato growers to transition from these products to other mode of action (MoA) groups for early-season L. decemlineata control. Continuous use of neonicotinoids has resulted in resistant L. decemlineata populations in some production areas of the eastern United States. Continued reliance on neonicotinoids will accelerate L. decemlineata resistance development and result in additional insecticide inputs to manage these populations. Resistance management recommendations for L. decemlineata have focused on rotation of insecticides within the growing season. Growers using at-plant neonicotinoids for early-season L. decemlineata control are encouraged to rotate MoAs for later generations to delay resistance development. Although this short-term insecticide rotation has likely prolonged the utility of neonicotinoid insecticides, reducing reliance on a single MoA soil application at planting will improve the longevity of newer, more reduced-risk alternatives. The objectives of this article are twofold: 1) to provide a review of the current status of L. decemlineata neonicotinoid resistance, and 2) to propose long-term resistance management strategies that arrange reduced-risk MoA groups into several, multiyear sequences that will maximize L. decemlineata control and reduce the probability for resistance development. This recommendation maintains practical and economical approaches for L. decemlineata control, but limits reliance on any single MoA group to minimize selection pressure for resistance development.}, number={4}, journal={Journal of Integrated Pest Management}, publisher={Oxford University Press (OUP)}, author={Huseth, Anders S. and Groves, Russell L. and Chapman, Scott A. and Alyokhin, Andrei and Kuhar, Thomas P. and Macrae, Ian V. and Szendrei, Zsofia and Nault, Brian A.}, year={2014}, month={Dec}, pages={1–8} }

 Emergence phenology and fitness attributes of several Colorado potato beetle, Leptinotarsa decemlineata (Say), populations were measured under field and greenhouse conditions. Anecdotal observations by producers and pest managers in many locations of the upper Midwest increasingly suggested that select populations of Colorado potato beetle were emerging over a longer period in the spring and were less sensitive to systemic neonicotinoids in cultivated potato. These changes in emergence phenologymaybe related to changes in systemic insecticide concentration over time. Specifically, a prolonged period of adult emergence in the spring increases the potential of low-dose chronic exposure to systemic neonicotinoid insecticides in potato. In 2010 and 2011, our objectives were twofold: 1) establish a common garden experiment to compare the emergence phenology of Colorado potato beetle populations uniquely managed with variable insecticide inputs, and 2) measure postdormancy fitness of emerged adult beetles from among these selected populations. Cumulative adult emergence was modeled with logistic regression. Results from this study found no clear evidence for direct relationships between phenology and management history or resistance. Differences in reproductive capacity, sex ratio, and body size were apparent in some instances. However, these results did not uniformly correspond to one specific form of potato pest management tested here. In this study, long-term reliance on systemic insecticides for Colorado potato beetle control did not serve as a strong predictor for variable life history for selected populations in Wisconsin.}, number={6}, journal={Journal of Economic Entomology}, publisher={Oxford University Press (OUP)}, author={Huseth, A.

The current study examines the relationship between beetle abundance in potato (Solanum tuberosum L.) and distance from multiple, previous year potato fields in Wisconsin, and integrates information about the influence of natural habitats adjacent to previous season potato. Colorado potato beetle count data were collected in 1998 and 2008 and distance to previous potato, field areas, and landscape classes were estimated using maps from 1997 and 2007. Poisson regression was used to relate counts to combinations of distance and local landscape characteristics calculated for all fields within 1,500 m of sampled potato. In 1998, beetle counts measured in current season potato declined significantly with increasing distance from previous potato fields and field size did not influence these counts. However, there was no relationship between beetle abundance and distance to prior year potatoes in 2008. In both years, increased proportions of surrounding habitats, previously described as preferred for diapause sites (e.g., wooded field boundaries), did not relate significantly to counts. However, grassland habitat was negatively correlated with counts. Results indicate that distance from previous potato remains an important factor to reduce the magnitude of colonization. This analysis further suggests that certain landscape components (e.g., grassland) may influence infestation, which may be useful for refining future integrated pest management programs.}, number={6}, journal={Environmental Entomology}, publisher={Oxford University Press (OUP)}, author={Huseth, A.

Both domestic and wild bee populations in central Wisconsin pickling cucumber fields were assessed using a combination of pan trapping and floral observations before and during bloom. Together with land cover analyses extending 2,000 m from field centers, the relationship of land cover components and bee abundance and diversity were examined. Over a 2-yr sample interval distributed among 18 experimental sites, 3,185 wild bees were collected representing >60 species. A positive association was found between both noncrop and herbaceous areas with bee abundance and diversity only during bloom. Response of bee abundance and diversity to land cover was strongest at larger buffers presumably because of the heterogeneous nature of the landscape and connectivity between crop and noncrop areas. These results are consistent with previous research that has found a weak response of wild bees to surrounding vegetation in moderately fragmented areas. A diverse community of wild bees is present within the fields of a commercial cucumber system, and there is evidence of floral visitation by unmanaged bees. This evidence emphasizes the importance of wild pollinators in fragmented landscapes and the need for additional research to investigate the effectiveness of individual species in pollen deposition.}, number={3}, journal={Environmental Entomology}, publisher={Oxford University Press (OUP)}, author={Lowenstein, D.
