As one method of genetic biocontrol, gene drive technology is currently being developed to manage the invasive agricultural pest spotted-wing drosophila (Drosophila suzukii, SWD). While there have been calls for stakeholder engagement on gene drive technology, there has been a lack of empirical work, especially concerning stakeholder engagement to inform risk assessment. To help address this gap and inform future risk assessments and governance decisions for SWD gene drive technology, we conducted a survey of 184 SWD stakeholders to explore how they define and prioritize potential benefits and potential adverse effects from proposed SWD gene drive technology. We found that stakeholders considered the most important potential benefits of SWD gene drive technology to be: 1) Decrease in the quantity or toxicity of pesticides used, and 2) Decrease in SWD populations. Stakeholders were most concerned about the potential adverse effects of: 1) Decrease in beneficial insects, 2) Increase in non-SWD secondary pest infestations, and 3) Decrease in grower profits. Notably, we found that even stakeholders who expressed support for the use of SWD gene drive technology expressed concerns about potential adverse effects from the technology, emphasizing the need to move past simplistic, dichotomous views of what it means to support or oppose a technology. These findings suggest that instead of focusing on the binary question of whether stakeholders support or oppose SWD gene drive technology, it is more important to identify and assess the factors that are consequential to stakeholder decision making - including, for example, exploring whether and under what conditions key potential adverse effects and potential benefits would result from the use of SWD gene drive technology.}, journal={JOURNAL OF ENVIRONMENTAL MANAGEMENT}, publisher={Elsevier BV}, author={Kokotovich, Adam E. and Barnhill-Dilling, S.

Tolerance for larvae is extremely low in fresh market fruit, and management is primarily achieved through repeated applications of broad-spectrum insecticides. These applications are neither economically nor environmentally sustainable, and can limit markets due to insecticide residue restrictions, cause outbreaks of secondary pests, and select for insecticide resistance. Sustainable integrated pest management programs include cultural control tactics and various nonchemical approaches for reducing pest populations that may be useful for managing D. suzukii. This review describes the current state of knowledge and implementation for different cultural controls including preventative tactics such as crop selection and exclusion as well as strategies to reduce habitat favorability (pruning; mulching; irrigation), alter resource availability (harvest frequency; sanitation), and lower suitability of fruit postharvest (cooling; irradiation). Because climate, horticultural practices, crop, and market underlie the efficacy, feasibility, and affordability of cultural control tactics, the potential of these tactics for D. suzukii management is discussed across different production systems.}, number={2}, journal={INSECTS}, author={Schoneberg, Torsten and Lewis, Margaret T. and Burrack, Hannah J. and Grieshop, Matthew and Isaacs, Rufus and Rendon, Dalila and Rogers, Mary and Rothwell, Nikki and Sial, Ashfaq A. and Walton, Vaughn M. and et al.}, year={2021}, month={Feb} }

We developed molecular methods to study adult D. suzukii gut content in order to understand its feeding habits. We designed and verified two primer pairs specific for either blueberries or blackberries and used a qPCR melt curve analysis to determine whether we can detect the presence or absence of berry feeding by adult flies. In a laboratory assay, the blueberry fly meal DNA can be detected for longer periods than the blackberry meal DNA. Generally, female gut contents are less variable than male gut contents. We also tested recently emerged flies that were not fed as adults but developed as larvae in either blueberries or blackberries. Some adult flies from each fruit had detectable fruit DNA in their gut, which could be due to pupal meconium feeding after emergence. Next, we aimed to test the primers in the field to develop techniques to track fruit feeding by D. suzukii in its natural field environment. First, to identify the most appropriate collection method, we determined how long we could detect fruit DNA, using previously developed primers within D. suzukii gut preserved in four types of trap fluid in the laboratory. The likelihood of detecting blackberry DNA differed by day, trap fluid, and between sexes. For the blueberry primer, the possibility of detecting blueberry DNA differed by trap fluid only. Based on those results, we used RV antifreeze with a Scentry SWD lure in field trials at two research station locations, one containing blackberries and one with blueberries. We established transects away from each fruit planting and collected up to 120 total flies at each point along transects. There were no significant differences in the number of flies containing berry DNA among collection points along the transect in both locations. These results suggest that adult flies move between crop and non-crop habitats and may not be highly dependent on fruit food resources.}, journal={Frontiers in Ecology and Evolution}, publisher={Frontiers Media SA}, author={Kraft, Laura J. and Sit, Tim L. and Diepenbrock, Lauren M. and Ashrafi, Hamid and Aryal, Rishi and Fernandez, Gina E. and Burrack, Hannah J.}, year={2021}, month={Aug} }

(Lepidoptera: Noctuidae) (tobacco budworm) management in pre-topped tobacco remains a concern for growers. Chlorantraniliprole, an anthranilic diamide insecticide, emerged as an option for C. virescens in early season tobacco because it selectively targets caterpillars, exhibits systemic action, and satisfies reduced risk classification. It is currently recommended for foliar application at threshold; however, because of its systemic action, many growers deploy soil applications at transplant. We conducted a series of experiments to determine the potential efficacy and longevity of soil applications of chlorantraniliprole for use against C. virescens in tobacco. First, tobacco plants were grown in the NCSU Phytotron, a controlled environment facility, and were treated with chlorantraniliprole soil applications either as a soil injection or soil drench at field equivalent rates at transplant. Plants were either watered daily or two times per week. A field experiment was established at two locations where at transplant in furrow and soil drench applications of chlorantraniliprole were compared to foliar applications. In both these experiments, one of the youngest leaves of adequate length on a subset of plants was sampled weeks three through nine after transplant in the phytotron and five through eight after transplant at the field stations. One-half of each leaf was exposed to second instar C. virescens to assess mortality and feeding, and the other half was analyzed for chlorantraniliprole concentration. Mortality differed between treatments in phytotron and field trials after 96 h exposure. Frass production and survivorship increased as plants grew. Phytotron trials demonstrated longer toxicity to C. virescens than field experiments, and chlorantraniliprole concentrations decreased at a slower rate in the Phytotron than in the field. Our field results suggest that soil applications of chlorantraniliprole are not likely to provide acceptable early season C. virescens control in the field.}, journal={CROP PROTECTION}, author={Zilnik, Gabriel and Kraus, Dylan A. and Burrack, Hannah J.}, year={2021}, month={Feb} }

Pruning small fruit crop canopies alters the microclimate, which in turn may influence insect pest activity. We investigated the effect of three canopy density treatments (high, medium, low) on Drosophila suzukii (Matsumura) (Diptera: Drosophilidae) fruit infestation in blueberries and caneberries using a two-year, multi-state experiment. We quantified the effect of canopy density on canopy microclimate, fruit quality (total soluble solids, fruit firmness), and yield. To better understand heterogeneity in canopy microclimate, parameters were further separated by canopy location (exterior vs. interior) in Maryland. In both crops, meta-analyses reveal small magnitude effects of the plant canopy on microclimate, whereas analysis of variance did not separate these effects, with mean canopy differences of 0.1–0.7 °C and 0.5–1.3 % relative humidity (RH) between caneberry canopy densities and locations. In caneberry multi-state trials, 0.14 fewer D. suzukii larvae (g fruit)−1 occurred on average in the low canopy density treatment, and 0.2 fewer D. suzukii larvae (g fruit)−1 occurred in exterior raspberries in Maryland compared with the canopy interior. Artificially infested blueberry fruit indicated immature D. suzukii survival within fruit can vary across canopy densities and locations. Although lower total yield was produced in low density canopies, canopy density did not influence berry quality or marketable yield.

Direct defenses, in the form of chemical and morphological components that inhibit pest damage, underlie host plant resistance, while indirect defenses including food provisioning and semiochemical production, improve biological control. Interactions between the two defensive strategies may be disruptive, complementary, or synergistic and are an important consideration for effective pest management programs. Glandular trichomes are plant structures that inhibit or entrap arthropods, protecting plants against herbivores, potentially at the cost of reducing natural enemy efficacy. Glandular trichomes may also contribute to indirect defense, as predatory arthropods adapted to “sticky” surfaces scavenge on entrapped arthropods. Scavenging increases predator abundance and reduces plant damage; this protective mutualism has been demonstrated with multiple sticky wild flowers but has not been assessed in an economically important plant, such as tobacco. We augmented dead arthropods (carrion) on tobacco plants grown under conditions similar to commercial production and assessed tri-trophic interactions. Carrion augmentation increased predator abundance, reduced damage to reproductive structures, and increased leaf yield, but did not reduce pest densities. We determined that systemic insecticide use did not affect carrion entrapment on tobacco plants. Review of the literature revealed that a variety of economically important plants entrap arthropods on their surfaces, indicating this mutualism has potential for development into a conservation biological control tactic.}, journal={BIOLOGICAL CONTROL}, author={Nelson, Peter N. and Burrack, Hannah J. and Sorenson, Clyde E.}, year={2019}, month={Oct} }

Physiological and morphological laboratory testing was performed on six commonly grown wine grape varieties inVirginia. Skin thickness, penetration force, and °Brix were analyzed to determine ovipositional preferences. Experiments were performed for three consecutive years from grapes collected at one Virginia vineyard. More eggs were laid in intact Viognier grapes than any other variety. Oviposition into intact grapes was not affected by skin thickness or °Brix; however, oviposition increased when penetration force decreased. An ovipositional choice test determined no varietal preferences. Survivorship from egg to adulthood using uninjured and injured grapes was also assessed to determine varietal suitability as D. suzukii hosts, with more flies emerging from injured grapes than uninjured. However, D. suzukii adults did emerge from intact grapes and at higher percentages than previously recorded in other wine grape studies. All varieties had eggs oviposited into them when injured. Determining the time at which each grape variety became susceptible to oviposition was determined using a D. suzukii bioassay spanning 12 wk using grapes from the green pea stage until ripe. Susceptibility to D. suzukii oviposition was based upon ripening period and penetration force. Early ripening varieties may be more susceptible to D. suzukii oviposition in the field with later maturing, harder fleshed-varieties which may escape D. suzukii oviposition.}, number={1}, journal={JOURNAL OF ECONOMIC ENTOMOLOGY}, author={Shrader, Meredith Edana and Burrack, Hannah J. and Pfeiffer, Douglas G.}, year={2019}, month={Feb}, pages={139–148} }

Previous research suggests that in temperate climates, the overwintering success of D. suzukii is likely dependent on access to food, shelter, and adequate cold hardening. We performed a multi-state study under field conditions for two winters to determine whether D. suzukii sex, phenotype (summer-morphotype, winter-morphotype), and life stage (adults, pupae) affected survival over time while recording naturally-occurring spatial and temporal variation in temperature. Access to food was provided and the flies were buried under leaf litter. Baited traps were deployed to determine whether local populations of D. suzukii were active throughout the winter season.The duration of exposure, mean daily temperature, and cumulative time below freezing significantly affected survival. Below freezing, D. suzukii survival was significantly reduced, particularly in northern locations. In contrast, we observed sustained survival up to 10 wk in southern locations among adults and pupae. Biotic factors also significantly affected survival outcomes: female survival was greater than male survival, winter-morphotype survival was greater than summer-morphotype survival, and adult survival was greater than pupal survival. In the north, wild D. suzukii were captured only in early winter, while in the south they were found throughout the winter. These data suggest that although adult D. suzukii may overwinter in sheltered microclimates, this ability may be limited in regions where the ground temperature, or site of overwintering, falls below freezing for extended durations.}, number={2}, journal={ENVIRONMENTAL ENTOMOLOGY}, author={Stockton, Dara and Wallingford, Anna and Rendon, Dalila and Fanning, Philip and Green, Clarence K. and Diepenbrock, Lauren and Ballman, Elissa and Walton, Vaughn M. and Isaacs, Rufus and Leach, Heather and et al.}, year={2019}, month={Apr}, pages={454–464} }

Control of this fly is achieved through insecticide sprays applied when ripening or ripe fruit are present. Monitoring to aid informed management decisions is challenging since trapping for adults is not a reliable indicator of potential or existing infestation in the fruit. Moreover, current larval monitoring techniques using brown sugar or salt solutions allow for visual detection of late-instar larvae, but they are time consuming and tend to miss smaller larvae. Here, we describe a method combining a salt solution, coffee filter, and microscope that can reliably and efficiently detect small and large larvae of D. suzukii in fruit samples. By sifting the sample liquid through an inexpensive coffee filter, larvae of all instars can be counted quickly and accurately. This method is 1.7 times faster than using a visual traybased method and can detect more larvae because first instar larvae can be detected. Growers can use this information to target insecticide sprays for curative control of small larvae, identify fields where the presence of larger larvae may indicate an unmarketable crop, or verify that no infestation exists and control programs are working.

An economic threshold for soybeans during the pod-filling stages exists to prevent economic damage to seeds. However, the impact of florivory (flower feeding) by H. zea larvae on seed yield is poorly understood and there is no economic threshold for flowering-stage soybeans. Four small plot experiments were conducted in North Carolina during 2011 and 2012 to assess the impact of H. zea feeding during the flowering stages of determinate soybeans on various yield components. Helicoverpa zea densities were manipulated with insecticides and various planting dates of soybeans and monitored weekly. Helicoverpa zea naturally infested the plots after flowering began and were allowed to feed until R3; they were eliminated from all plots from R3 to maturity. In some sites, H. zea densities exceeded the podding economic threshold during the flowering stages, but yield did not differ among treatments. During 2012, florivory from H. zea was measured directly by counting injured flowers. There was a negative yield relationship between both injured flower number and cumulative flower number. Moreover, H. zea densities were related to both a decrease in cumulative flowers and an increase in injured flowers, even though a direct linkage between H. zea density and yield loss was not observed. Without knowing the preferred tissue types and performance of early-instar larvae on soybeans, it is possible that H. zea density may not be the best measurement for developing an economic threshold in flowering soybeans.}, number={2}, journal={J.

This injury is of concern to commercial strawberry growers, who typically assume the loss of one clipped bud is the loss of one average sized fruit, causing the economic threshold to be set extremely low. There is evidence of compensation in some cultivars of strawberries, but research has previously only been conducted in perennial strawberry production. The majority of strawberries in the southeastern United States are grown in annual plasticulture systems. We assessed the ability of five strawberry cultivars commonly grown in annual plasticulture to compensate for A. signatus injury by removing buds at different growth stages.

Cold storage at 1.1 °C for 24 h decreased larval survival, but shorter durations generally did not affect larval survival. No eggs or young larvae survived when held for 72 h at 1.1 °C, and fewer older larvae survived after 72 h at 1.1, 3.9, and 5.0 °C than at 20 °C (control).

Consumption indices were calculated and observed feeding behaviors were used to indicate preference; survival, growth rate, and larval body mass were recorded as measures of performance. Second instars performed better when fed leaf tissue than when fed other tissue types. In no-choice assays, 32% of 2nd instars that fed exclusively on newly emerging trifoliates reached the pupal stage, and 50% of those that fed exclusively on fully emerged leaf trifoliates survived to pupation. Early instar survival was poor (ranging from 0 to 3%) on all other tissue types, including flowers, stems, and pods. However, when given a choice of tissue types throughout their larval lifetime, 2nd instars preferred to feed on newly emerging trifoliates and early developing pods, consuming on average 51 and 38%, respectively, of each tissue type. In no-choice assays, 4th instars performed best on pods with fully developed seeds; however, when presented with a choice throughout their lifetime, late instars did not feed at a higher rate on any single tissue type.

The virus has been reported in the U.K. in blackberry (Jones and McGavin 1998) but its presence in the host in the United States is unknown. A survey was carried out in the Southeast and Midwest to ascertain whether the virus infects commercial and wild blackberries, and to evaluate its potential role in the recent outbreak of blackberry yellow vein disease (BYVD; Martin et al. 2013). A total of 247 BYVD-affected plants, collected from Arkansas, Florida, Georgia, Illinois, North Carolina, South Carolina, and West Virginia between 2008 and 2011 were screened by RT-PCR for the presence of RLMV as described in Tzanetakis et al. (2007). Four plants tested positive, two cultivated (Arkansas and North Carolina), and two wild blackberries from Arkansas. All amplicons (452 bp) were sequenced to confirm their identity and revealed 99 to 100% identity between each other at the nucleotide and amino acid levels (GenBank accessions KX431258 to 61), as well as with the type isolate (DQ357218). Additionally, the presence of RLMV was confirmed by RNA blot hybridization (Thekke Veetil and Tzanetakis 2016). The PCR amplicons were cloned into a Topo2.1 cloning vector and an insert was subjected to digoxigenin probe synthesis and used for virus detection according to manufacturer’s protocol (DIG High Prime DNA Labeling and Detection Starter Kit II, Roche Life Science), by blotting total nucleic acids (900 ng) from all infected and healthy blackberry controls onto a positively charged nylon membrane (GE Healthcare Life Sciences). This is the first report of RLMV in blackberry in the United States. Its low incidence in commercial fields and wild blackberries indicates that RLMV is not a major player in the BYVD outbreak. The apparently low incidence of RLMV in commercial blackberry plantings suggests that RLMV does not circulate in propagation material. The virus is transmitted by the large raspberry aphid (Amphorophora agathonica Hottes) and because of the low incidence of the vector in the areas assayed (Johnson and Burrack, unpublished), RLMV is not expected to be a major risk factor for the industry.References:Jones, A.

Growers rely on various management approaches such as resistant wheat varieties, crop rotation, timely plantings, and insecticide treatments to control this destructive pest. The objectives for this research were to show the efficacy of a common insecticide seed treatment (imidacloprid) and a common foliar insecticide spray (lambda-cyhalothrin) on Hessian fly abundance in wheat. Four experiments were conducted over two years in North Carolina, in order to manipulate Hessian fly abundance. Small plot studies were designed with whole plot treatments including non-treated and imidacloprid treated wheat seed, and subplots split with a semi-monthly foliar lambda-cyhalothrin application or no foliar insecticide. The number of Hessian fly eggs present on leaves, number of larvae, number of pupae, and tiller density were counted for the fall generation(s) and all plots were sprayed with foliar insecticide during the spring. Wheat seed treated with imidacloprid had fewer eggs, larvae, and pupae compared to other non-treated seed. With one exception during 2014, foliar spray applications did not reduce egg, larvae, and pupae abundance. Warmer temperatures during 2015 experiments provided conditions that extended Hessian fly presence, allowing multiple fall generations to infest wheat.

A combination of laboratory and field studies was conducted to develop prediction and potential management tools. First, a direct bioassay was used to calculate the probability of oviposition in a given fruit based on various characteristics as determined across laboratory and field trials in Oregon and North Carolina, US. When multiple characteristics were evaluated simultaneously, oviposition probability consistently increased as penetration force decreased and pH increased. Oviposition probability sometimes increased as TSS increased. Second, raspberries and blueberries in unsprayed fields had substantially lower infestation in ripening fruit compared to ripe fruit. There was no or minimal infestation in green fruit. Third, given that skin penetration force influences oviposition, practices used to improve fruit quality were examined in laboratory no-choice cages for potential reduction of oviposition. Blueberry fruit sprayed with calcium silicate in the field had greater penetration force and firmness and reduced number of eggs laid by D. suzukii compared to untreated fruit.

Females use their saw-like ovipositor to lay eggs in soft-skinned fruits and severely threaten the viability of raspberry, blackberry, blueberry, cherry, and strawberry production. In a recent study, females in nochoice laboratory bioassays laid eggs in ripening blueberries and blackberries. However, most of the eggs failed to develop, perhaps because the ripening process was interrupted in the prematurely-harvested fruit. We hypothesized that eggs laid in ripening fruit in a field may be able to complete development as the fruit continues to ripen. To test this hypothesis, we used fine mesh cages to prevent later egg laying by D. suzukii in fruit at several ripeness stages: green-pink, pink, and ripe raspberries and in green-pink, red, purple, and ripe blackberries. We collected the fruit once they were ripe, and reared out and counted all D. suzukii present. This experiment was conducted at two locations during 2013 and 2014, one with very high fly populations and one with low populations. Very few flies emerged from blackberry clusters that were bagged at the green-pink stage, and in general, more flies emerged from clusters bagged at later stages of ripening (purple and red blackberries and pink raspberries) than from green-pink fruit. Knowing what ripeness stages are susceptible to D. suzukii infestation will help growers to better pinpoint when to begin applying management tools.}, journal={XI INTERNATIONAL RUBUS AND RIBES SYMPOSIUM}, author={Swoboda-Bhattarai, K.

All insecticide applications had greater adult acute mortality than controls, and some had residual efficacy for three or more days after treatment.

 Drosophila suzukii Matsumara, also referred to as the spotted wing drosophila, has recently expanded its global range with significant consequences for its primary host crops: blueberries, blackberries, raspberries, cherries, and strawberries. D. suzukii populations can increase quickly, and their infestation is difficult to predict and prevent. The development of effective tools to detect D. suzukii presence in new areas, to time the beginning of activity within a crop, to track seasonal activity patterns, and to gauge the effectiveness of management efforts has been a key research goal. We compared the efficiency, selectivity, and relationship to fruit infestation of a range of commonly used homemade baits and a synthetic formulated lure across a wide range of environments in 10 locations throughout the United States. Several homemade baits were more efficient than apple cider vinegar, a commonly used standard, and a commercially formulated lure was, in some configurations and environments, comparable with the most effective homemade attractant as well as potentially more selective. All alternative attractants also captured flies between 1 and 2 wk earlier than apple cider vinegar, and detected the presence of D. suzukii prior to the development of fruit infestation. Over half the Drosophila spp. flies captured in traps baited with any of the attractants were not D. suzukii, which may complicate their adoption by nonexpert users. The alternative D. suzukii attractants tested are improvement on apple cider vinegar and may be useful in the development of future synthetic lures.}, number={3}, journal={ENVIRONMENTAL ENTOMOLOGY}, author={Burrack, Hannah J. and Asplen, Mark and Bahder, Luz and Collins, Judith and Drummond, Francis A. and Guedot, Christelle and Isaacs, Rufus and Johnson, Donn and Blanton, Anna and Lee, Jana C. and et al.}, year={2015}, month={Jun}, pages={704–712} }

We surveyed the bee community (through transect sampling and pan trapping) and measured pollination of both open- and singly-visited flowers.

Wild-bee richness was a better predictor of pollination than wild-bee abundance.

Thus, we suggest alternative experiments for validation. The model is advantageous in that it provides stage-specific population estimation, which can potentially guide management strategies and provide unique opportunities to simulate stage-specific management effects such as insecticide applications or the effect of biological control on a specific life-stage.

 Numerous bee species provide pollination services in agricultural ecosystems. Evaluating a pollinator's performance with regard to a crop is an important step in attributing pollination services and predicting how changes in a bee community or foraging environment will affect those services. We used multiple criteria to evaluate pollinators of North Carolina highbush blueberry, Vaccinium corymbosum L., agroecosystems. For five groups of bees (Apis mellifera L., Bombus spp., Habropoda laboriosa F., small native bees, and Xylocopa virginica L.), we measured forager abundance through transect observations, quantified per-visit efficiency as viable seed set resulting from a single visit, and analyzed bee presence in different weather conditions.Wealso considered two other criteria affecting pollinator performance—visitation rate and interspecific influence. A. mellifera was the most abundant bee in the majority of our survey sites, yet had low per-visit efficiency and reduced foraging activity in inclement weather. Small native bees were highly efficient pollinators. Their visits resulted in nearly twice as many seeds as A. mellifera or H. laboriosa. Bombus spp., H. laboriosa, and small native bees were more resilient to fluctuations in temperature, wind speed, and solar radiation than A. mellifera. Although nectar-robbing X. virginica contributed to little pollination through direct flower visits, their presence within the crop impacts the behavior and performance of other individuals. Underscoring the importance of evaluating pollinator performance via multiple criteria, our results show that bee groups contribute to pollination in different ways. These differences may provide functional complementarity and stability of pollination services to agricultural systems.}, number={6}, journal={ENVIRONMENTAL ENTOMOLOGY}, author={Rogers, Shelley R. and Tarpy, David.

Drosophila suzukii, a pest of soft-skinned berries and stone fruits, has recently rapidly expanded its global range. The impacts of D. suzukii infestation and subsequent fruit damage in North America and Europe have been profound. The aim of the present work was to assess host selection of D. suzukii in the field and laboratory, with an emphasis on hosts commonly grown in the southeastern United States, where D. suzukii has been established since 2010.


RESULTS
Raspberries were infested at a greater rate than blackberries in the field, and varieties within both species were infested at different rates. Primocane-fruiting blackberries were often the least heavily infested. Further, blackberries and raspberries grown under high tunnels were infested at lower rates than those grown outside. Fruit and artificial substrates with a lower surface penetration force were more heavily infested than firmer substrates in the laboratory; no eggs were laid in artificial substrates exceeding 52.00 cN surface penetration force.


CONCLUSION
Infestation rates differ between species and varieties within species of Rubus in the southeastern United States. Fruit penetration force is one potential measure of host susceptibility, but host attractiveness will likely depend upon additional factors, such as soluble sugar content.}, number={10}, journal={PEST MANAGEMENT SCIENCE}, author={Burrack, Hannah J. and Fernandez, Gina E. and Spivey, Taylor and Kraus, Dylan A.}, year={2013}, month={Oct}, pages={1173–1180} }

Although fly catches among traps varied per site, overall, the Haviland trap caught the most D. suzukii, followed by the red, Van Steenwyk, and clear trap. The modified Haviland and commercial trap had low captures. Among five crop types in Oregon, a clear cup with mesh sides (Dreves) also was tested and caught the most flies. Traps with greater entry areas, found in mesh traps, caught more flies than traps with smaller entry areas.

 The microbiome of the olive fruit fly, Bactrocera oleae (Gmelin), a worldwide pest of olives (Olea europaea L.), has been examined for >100 yr as part of efforts to identify bacteria that are plant pathogens vectored by the fly or are beneficial endosymbionts essential for the fly's survival and thus targets for possible biological control. Because tephritid fruit flies feed on free-living bacteria in their environment, distinguishing between the transient, acquired bacteria of their diet and persistent, resident bacteria that are vertically transmitted endosymbionts is difficult. Several culture-dependent and -independent studies have identified a diversity of species in the olive fruit fly microbiome, but they have not distinguished the roles of the microbes. Candidatus Erwinia dacicola, has been proposed to be a coevolved endosymbiont of the olive fruit fly; however, this was based on limited samples from two Italian populations. Our study shows that C. Erwinia dacicola was present in all New and Old World populations and in the majority of individuals of all life stages sampled in 2 yr. Olive fruit flies reared on olives in the laboratory had frequencies of C. Erwinia dacicola similar to that of wild populations; however, flies reared on artificial diets containing antibiotics in the laboratory rarely had the endosymbiont. The relative abundance of C. Erwinia dacicola varied across development stages, being most abundant in ovipositing females and larvae. This uniform presence of C. Erwini dacicola suggests that it is a persistent, resident endosymbiont of the olive fruit fly.}, number={2}, journal={ENVIRONMENTAL ENTOMOLOGY}, author={Estes, Anne M. and Hearn, David J. and Burrack, Hannah J. and Rempoulakis, Polychronis and Pierson, Elizabeth A.}, year={2012}, month={Apr}, pages={265–274} }

If left unchecked, R. mendax infestations can reach nearly 100%. Larvae feed internally, and infested fruit can be difficult to identify without destructive sampling, making it possible for infested fruit to be missed in the sorting process. Because of this damage potential and cryptic injury, Canada has imposed import restrictions for R. mendax, which is not established in some western blueberry growing regions. Nearly all of North Carolina's blueberry growers export a portion of their crop to Canada and are subject to quarantine restrictions. All of the growers certified for export to Canada currently operate under a scheduled spray program (relying mostly on organophosphate insecticides), even though the Canadian phytosanitary protocol allows for a monitoring based (and likely reduced insecticide) management regime. We conducted blueberry maggot monitoring at 14 North Carolina blueberry fields to determine the feasibility of implementing a monitoring based R. mendax management program and to assess the potential insecticide reduction under such a monitoring based program. Results from 2010 indicate that significant reductions in insecticide applications could be achieved if monitoring was implemented.}, number={1-3}, journal={International Journal of Fruit Science}, publisher={Informa UK Limited}, author={Burrack, Hannah J. and Littlejohn, Kevin}, year={2012}, month={Jan}, pages={106–113} }

Herein, we consider a management problem in which a bioeconomic system exhibits simultaneity in processes governing productivity and damage. In this case, it may benefit the producer to sacrifice productivity to reduce the costs associated with increased damage. We specify empirically a structural damage relationship that explains the biological process by which an invasive species damages a host and estimate the structural model and its reduced form with an exceptional dataset on infestation of olives by the olive fruit fly. We contrast the results of these models with the approach typically taken in the economic literature, which expresses damage as a function of pest density. The population-based approach introduces significantly greater bias into the individual grower's choice of damage-control inputs than estimates based on the structural model.}, number={2}, journal={JOURNAL OF ENVIRONMENTAL ECONOMICS AND MANAGEMENT}, author={Cobourn, Kelly M. and Burrack, Hannah J. and Goodhue, Rachael E. and Williams, Jeffrey C. and Zalom, Frank G.}, year={2011}, month={Sep}, pages={278–289} }

 Olive fruit flies [Bactrocera oleae (Gmelin) ] occur at densities in California that can result in intraspecific larval competition within infested fruit. Larval B. oleae densities tracked in the field at six location were found to be highly variable and related to the proportion of fruit infested and adult densities. Egg and larval distribution within the field was generally aggregated early in the season and trended toward random and uniform as the season progressed. To determine whether B. oleae experienced fitness consequences at a range of larval densities observed in the field, olive fruits were infested with one, two, four, and six eggs, and larval and pupal developmental time, pupal weight, and pupal yield were compared. At the highest egg density, all measures of performance were negatively impacted, resulting in fewer and lighter pupae that took longer to pupate and emerge as adults, and even when only two larvae was present per olive, resulting pupae were significantly smaller. Density did not impact the sex ratio of the resulting flies or survive to adults. As field surveys showed, larval densities ranged from 1 to 11 B. oleae per fruit at some sites, and our results suggest that, at high densities, B. oleae do experience competition for larval resources. The impact of intraspecific larval competition North American in field populations of B. oleae is unknown, but the potential for competition is present.}, number={5}, journal={ENVIRONMENTAL ENTOMOLOGY}, author={Burrack, Hannah Joy and Fornell, Angela M. and Connell, Joseph H. and Neil V.

In the second year, three variants of AM yellow sticky traps were included in testing. The AM yellow sticky panel was more efficient than the ChamP panel. The ChamP and AM traps were baited with an ammonium bicarbonate food lure and Spiroketal pheromone lure, and the McPhail traps were baited with a torula yeast food lure. Under the conditions of this study, it appears that the aqueous food lure used in the McPhail traps was more attractive to olive fruit flies than ammonia lures. Traps were also deployed in irrigated and unirrigated olive blocks at one location for 1 year, and more olive fruit flies were caught in the irrigated trees than in the unirrigated.

The objectives of this study were to determine whether B. oleae exhibits ovipositional preference under California field conditions similar to that demonstrated in European populations and whether the resulting larvae fare better in preferred varieties. Female B. oleae exhibited strong ovipositional preference for certain varieties of the domesticated olive, Olea europaea L, and the resulting larvae performed better by some measures in preferred varieties than in lesser preferred varieties. Ovipositional preference was observed in the field from 2003 to 2005, and laboratory assays were conducted to evaluate larval performance in 2005 and 2006. Among the olive varieties tested, Sevillano, Manzanillo, and Mission olives were the most heavily infested during three consecutive years. The larval performance measurements used were pupal yield, pupal weight, larval developmental time, and pupal emergence time. Ovipositional preference and pupal yield do not seem associated. There were significant differences in pupal emergence time, but these also measures did not reflect ovipositional preference. Two measures on performance did seem related to ovipositional preference; there were significant effects of variety on pupal weight and larval developmental time. Pupae developing in Manzanillo and Sevillano olives were heavier than those developing in less preferred varieties, and larval developmental time was significantly shorter in Sevillano olives relative to the other varieties. Oviposition preference and enhanced larval performance has implications for the pest status of this invasive insect in California.}, number={3}, journal={JOURNAL OF ECONOMIC ENTOMOLOGY}, author={Burrack, Hannah Joy and Zalom, Frank G.}, year={2008}, month={Jun}, pages={750–758} }
