We hypothesized that transect-based designs could give similar detection rates with significantly shorter servicing distances. We used the TrapGrid model to investigate novel “trap-sect” designs incorporating crossed, spoked, and parallel lines of traps, comparing them to a regular grid, in single survey and multiple-site scenarios. We calculated minimum servicing distances and simulated mean probabilities of detecting a pest population, judging overall performance of trap network designs using both metrics. For single sites, trap-sect designs reduced service distances by 65–89%, and most had similar detection probabilities as the regular grid. Kernel-smoothed intensity plots indicated that the best performing trap-sect designs distributed traps more fully across the area. With multiple sites (3 side by side), results depended on insect dispersal ability. All designs performed similarly in terms of detection for highly mobile insects, suggesting that designs minimizing service distances would be best for such pests. For less mobile pests the best trap-sect designs had 4–6 parallel lines, or 8 spokes, which reduced servicing distances by 33–50%. Comparisons of hypothetical trap-sect arrays to real program trap locations for 2 pests demonstrated that the novel designs reduced both trap numbers and service distances, with little differences in mean nearest trap distance to random pest locations. Trap-sect designs in delimitation surveys could reduce costs and increase program flexibility without harming the ability to detect populations.}, journal={JOURNAL OF ECONOMIC ENTOMOLOGY}, author={Caton, Barney P. and Fang, Hui and Pallipparambil, Godshen R. and Manoukis, Nicholas C.}, year={2023}, month={Apr} } @article{gowda_shrestha_harris_phillips_fang_sood_zhang_bourland_bart_kuraparthy_2022, title={Identification and genomic characterization of major effect bacterial blight resistance locus (BB-13) in Upland cotton (Gossypium hirsutum L.)}, volume={10}, ISSN={["1432-2242"]}, url={https://publons.com/wos-op/publon/54751063/}, DOI={10.1007/s00122-022-04229-2}, abstractNote={Identification and genomic characterization of major resistance locus against cotton bacterial blight (CBB) using GWAS and linkage mapping to enable genomics-based development of durable CBB resistance and gene discovery in cotton. Cotton bacterial leaf blight (CBB), caused by Xanthomonas citri subsp. malvacearum (Xcm), has periodically been a damaging disease in the USA. Identification and deployment of genetic resistance in cotton cultivars is the most economical and efficient means of reducing crop losses due to CBB. In the current study, genome-wide association study (GWAS) of CBB resistance using an elite diversity panel of 380 accessions, genotyped with the cotton single nucleotide polymorphism (SNP) 63 K array, and phenotyped with race-18 of CBB, localized the CBB resistance to a 2.01-Mb region in the long arm of chromosome D02. Molecular genetic mapping using an F 6 recombinant inbred line (RIL) population showed the CBB resistance in cultivar Arkot 8102 was controlled by a single locus (BB-13). The BB-13 locus was mapped within the 0.95-cM interval near the telomeric region in the long arm of chromosome D02. Flanking SNP markers, i04890Gh and i04907Gh of the BB-13 locus, identified from the combined linkage analysis and GWAS, targeted it to a 371-Kb genomic region. Candidate gene analysis identified thirty putative gene sequences in the targeted genomic region. Nine of these putative genes and two NBS-LRR genes adjacent to the targeted region were putatively involved in plant disease resistance and are possible candidate genes for BB-13 locus. Genetic mapping and genomic targeting of the BB13 locus in the current study will help in cloning the CBB-resistant gene and establishing the molecular genetic architecture of the BB-13 locus towards developing durable resistance to CBB in cotton.}, journal={THEORETICAL AND APPLIED GENETICS}, publisher={Springer Science and Business Media LLC}, author={Gowda, S.

We investigated grid compositions and design factors, measuring performance as the mean probability of pest capture over all traps, p(capture), and designed improved grids for both species. For the standard designs, p(capture) was 0.86 for leek moth and 0.71 for Medfly, with the latter performing better due to greater lure and trap attractiveness. For both designs, 86 percent or more of mean p(capture) came from core area captures. Egress testing indicated that both grids were oversized. An improved grid for leek moths would use 177 traps in a 4.8-km diameter circle, which had mean p(capture) = 0.73 and reduced the cost by 80 percent. The best Medfly grid was a 4.8-km diameter circle with 232 traps, which gave mean p(capture) of 0.66 and reduced the cost by 86 percent.

We analysed trapping survey detections data for five insects and one low‐dispersing mollusc to quantify 30‐day dispersal kernels (mean total distance [MTD], m). We hypothesized that MTD would increase with species’ reported diffusion coefficients (D, m2 per day), and that D could be used to predict containment radius lengths for delimiting surveys for exotic pests. We collected trapping data for the following six invasive pest species: European grapevine moth (EGVM; Lobesia botrana [Denis & Schiffermüller]), Giant African land snail (GALS; Lissachatina fulica [Bowdich]), Japanese beetle (JB; Popillia japonica [Newman]), Mediterranean fruit fly (Medfly; Ceratitis capitata [Wiedemann]), Mexican fruit fly (Mexfly; Anastrepha ludens [Loew]) and Oriental fruit fly (OFF; Bactrocera dorsalis [Hendel]). We used K‐means clustering to group detections that were proximate in space and time, then finalized them manually. We calculated MTD from the cluster centroid for each detection. Probability histograms for MTD were fit to a two‐parameter exponential function, and from those functions we estimated species’ dispersal limits for four percentiles (99th to 99.99th). The least vagile species, GALS and EGVM, had the greatest decay rates, and smallest MTD and percentile distances. OFF, with the greatest reported D, had the smallest decay rates and greatest MTD and percentile distances. Medfly, Mexfly and JB had intermediate MTD and percentile distances. Each regression of percentile distance as a logarithmic function of D fit the data well. The best regression used adjusted 99.9th percentile distances. These empirical results indicated that many delimiting surveys currently in use are oversized; adopting the new recommendations could yield significant cost savings.

Delimitation includes verifying the presence of the pest and determining its spatial extent. The size and shape of the survey design and the density of traps can vary; however, resulting variation in detecting efficiency is often unknown. We used a trapping network simulation model with diffusion-based insect movement to investigate delimiting survey trapping design performance for fully trapped and some modified designs. Simulations included randomized outbreak locations in a core area and a duration of 30 d. We assessed impacts of insect dispersal ability, grid size and shape, and trap attractiveness and density on survey performance, measured as mean probability of capturing individual pests [p(capture)]. Most published grids are square, but circles performed equally well and are more efficient. Over different grid sizes, p(capture) increased for insects with greater dispersal ability but was generally unresponsive to size because most captures occurred in central areas. For low dispersing insects, the likelihood of egress was approximately zero with a 3.2-km square grid, whereas an 11.3-km grid was needed to contain highly vagile insects. Trap attractiveness affected p(capture) more strongly than density: lower densities of poorly attractive traps may underperform expectations. Variable density designs demonstrated potential for cost savings but highlighted that resource-intensive outer bands are critical to boundary determination. Results suggesting that many grids are oversized need empirical verification, whereas other principles, such as using circular shapes, are readily adoptable now.}, number={6}, journal={JOURNAL OF ECONOMIC ENTOMOLOGY}, author={Caton, Barney P. and Fang, Hui and Manoukis, Nicholas C. and Pallipparambil, Godshen R.}, year={2021}, month={Dec}, pages={2581–2590} } @article{zhang_kuraparthy_fang_zhu_sood_jones_2019, title={High-density linkage map construction and QTL analyses for fiber quality, yield and morphological traits using CottonSNP63K array in upland cotton (Gossypium hirsutum L.)}, volume={20}, ISSN={["1471-2164"]}, url={https://publons.com/wos-op/publon/36765240/}, DOI={10.1186/s12864-019-6214-z}, abstractNote={AbstractBackgroundImproving fiber quality and yield are the primary research objectives in cotton breeding for enhancing the economic viability and sustainability of Upland cotton production. Identifying the quantitative trait loci (QTL) for fiber quality and yield traits using the high-density SNP-based genetic maps allows for bridging genomics with cotton breeding through marker assisted and genomic selection. In this study, a recombinant inbred line (RIL) population, derived from cross between two parental accessions, which represent broad allele diversity in Upland cotton, was used to construct high-density SNP-based linkage maps and to map the QTLs controlling important cotton traits.ResultsMolecular genetic mapping using RIL population produced a genetic map of 3129 SNPs, mapped at a density of 1.41 cM. Genetic maps of the individual chromosomes showed good collinearity with the sequence based physical map. A total of 106 QTLs were identified which included 59 QTLs for six fiber quality traits, 38 QTLs for four yield traits and 9 QTLs for two morphological traits. Sub-genome wide, 57 QTLs were mapped in A sub-genome and 49 were mapped in D sub-genome. More than 75% of the QTLs with favorable alleles were contributed by the parental accession NC05AZ06. Forty-six mapped QTLs each explained more than 10% of the phenotypic variation. Further, we identified 21 QTL clusters where 12 QTL clusters were mapped in the A sub-genome and 9 were mapped in the D sub-genome. Candidate gene analyses of the 11 stable QTL harboring genomic regions identified 19 putative genes which had functional role in cotton fiber development.ConclusionWe constructed a high-density genetic map of SNPs in Upland cotton. Collinearity between genetic and physical maps indicated no major structural changes in the genetic mapping populations. Most traits showed high broad-sense heritability. One hundred and six QTLs were identified for the fiber quality, yield and morphological traits. Majority of the QTLs with favorable alleles were contributed by improved parental accession. More than 70% of the mapped QTLs shared the similar map position with previously reported QTLs which suggest the genetic relatedness of Upland cotton germplasm. Identification of QTL clusters could explain the correlation among some fiber quality traits in cotton. Stable and major QTLs and QTL clusters of traits identified in the current study could be the targets for map-based cloning and marker assisted selection (MAS) in cotton breeding.

Theokralocus is not only of agricultural importance in cotton (Gossypium hirsutumL.), but through pioneering chimeric and morphometric studies it has contributed to fundamental knowledge about leaf development.

Development of VW‐resistant cultivars remains the only economic option for controlling the disease. The objective of this review was to summarize the progress in screening methods, resistance sources, and genetics, quantitative trait locus (QTL) mapping, marker‐assisted selection (MAS) and breeding for VW resistance in cotton. Even though Gossypium barbadense L. carries high levels of resistance, its resistance has not been transferred into commercial Upland cultivars. Many Acala cotton cultivars developed in New Mexico and California between the 1940s and the 1990s, and some commercial transgenic cultivars are tolerant or moderately resistant to VW. However, due to difficulties in achieving consistent and uniform inoculation and infection with V. dahliae, both qualitative and quantitative inheritance of VW resistance have been reported in numerous studies for resistant G. barbadense and Upland genotypes. Several QTL analyses have shown the existence of VW resistance QTLs on almost all the tetraploid cotton chromosomes; however, QTLs have most frequently been detected on c5, c7, c8, c11, c16, c17, c19, c21, c23, c24, and c26. This has led to MAS for progeny with favorable QTL alleles for VW resistance in several experiments. Phenotypic selection for VW resistance has been inefficient, while the effectiveness and efficiency of MAS remain to be validated. There is an urgent need for the development of better plant inoculation and screening methods, and for more molecular mapping studies to discern the genetic basis of VW resistance in cotton.}, number={4}, journal={Crop Science}, publisher={Wiley}, author={Zhang, Jinfa and Fang, Hui and Zhou, Huiping and Sanogo, Soum and Ma, Zhiying}, year={2014}, month={Jul}, pages={1289–1303} } @article{zhou_fang_sanogo_hughs_jones_zhang_2014, title={Evaluation of Verticillium wilt resistance in commercial cultivars and advanced breeding lines of cotton}, volume={196}, url={http://dx.doi.org/10.1007/s10681-013-1045-5}, DOI={10.1007/s10681-013-1045-5}, number={3}, journal={Euphytica}, publisher={Springer Science and Business Media LLC}, author={Zhou, Huiping and Fang, Hui and Sanogo, Soum and Hughs, Sidney E. and Jones, Don C. and Zhang, Jinfa}, year={2014}, month={Apr}, pages={437–448} } @article{inheritance and transfer of thrips resistance from pima cotton to upland cotton_2013, url={https://www.cotton.org/journal/2013-17/3/}, journal={Journal of Cotton Science}, year={2013}, month={Feb} } @article{fang_zhou_sanogo_lipka_fang_percy_hughs_jones_gore_zhang_2014, title={Quantitative trait locus analysis of Verticillium wilt resistance in an introgressed recombinant inbred population of Upland cotton}, volume={33}, url={http://dx.doi.org/10.1007/s11032-013-9987-9}, DOI={10.1007/s11032-013-9987-9}, number={3}, journal={Molecular Breeding}, publisher={Springer Science and Business Media LLC}, author={Fang, Hui and Zhou, Huiping and Sanogo, Soum and Lipka, Alexander E. and Fang, David D. and Percy, Richard G. and Hughs, Sidney E. and Jones, Don C. and Gore, Michael A. and Zhang, Jinfa}, year={2014}, month={Mar}, pages={709–720} } @article{fang_zhou_sanogo_flynn_percy_hughs_ulloa_jones_zhang_2013, title={Quantitative trait locus mapping for Verticillium wilt resistance in a backcross inbred line population of cotton (Gossypium hirsutum × Gossypium barbadense) based on RGA-AFLP analysis}, volume={194}, url={http://dx.doi.org/10.1007/s10681-013-0965-4}, DOI={10.1007/s10681-013-0965-4}, number={1}, journal={Euphytica}, publisher={Springer Science and Business Media LLC}, author={Fang, Hui and Zhou, Huiping and Sanogo, Soum and Flynn, Robert and Percy, Richard G. and Hughs, Sidney E. and Ulloa, Mauricio and Jones, Don C. and Zhang, Jinfa}, year={2013}, month={Nov}, pages={79–91} } @article{revilla-molina_bastiaans_keulen_kropff_hui_castilla_mew_zhu_leung_2009, title={Does resource complementarity or prevention of lodging contribute to the increased productivity of rice varietal mixtures in Yunnan, China?}, volume={111}, url={http://dx.doi.org/10.1016/j.fcr.2009.01.003}, DOI={10.1016/j.fcr.2009.01.003}, abstractNote={We conducted an experiment in Gejiu, Yunnan Province of China during the wet season of 2002 to examine the importance of resource complementarity and prevention of lodging in the fast-spreading practice of growing rice varietal mixtures in China to suppress rice blast disease and its associated damage. The hybrid rice variety Shanyou 63 and the glutinous or sticky rice variety Huangkenuo were used to study intra- and inter-varietal competition in the rice intercropping system. The experiment was laid out as a randomized complete block design in four replications with pure stands and mixtures of both varieties at different total planting densities and mixing ratios. In half of the pure stand treatments of glutinous rice a metal frame was installed to prevent lodging. The results showed that resource complementarity between the two rice varieties, resulting from niche differentiation, was marginal and did not greatly enhance the productivity of the rice varietal mixtures. In contrast, prevention of lodging of glutinous rice was identified as an important additional advantage of growing these rice varieties in mixture.}, number={3}, journal={Field Crops Research}, publisher={Elsevier BV}, author={Revilla-Molina, I.M. and Bastiaans, L. and Keulen, H.

The glutinous cultivars were 35 to 40 cm taller and substantially more susceptible to blast than was the nonglutinous cultivar. Interplanting of glutinous and nonglutinous rice reduced the incidence and severity of panicle blast on the glutinous cultivars by >90%, and on the nonglutinous cultivar by 30 to 40%. Mixing increased the per unit area yield of glutinous rice by 80 to 90% relative to pure stand, whereas yield of the nonglutinous cultivar was essentially unaffected by mixing. To determine whether the different plant heights and canopy structures may contribute to a microclimate that is less favorable to blast infection, we monitored the moisture status of the glutinous cultivars in pure stand and mixture at 0800 h by measuring relative humidity at the height of the glutinous panicles using a swing psychrometer and by visually estimating the percentage of leaf area covered by dew. Averaged over the two seasons, the number of days of 100% humidity at 0800 h was 20.0 and 2.2 for pure stands and mixtures, respectively. The mean percentage of glutinous leaf area covered by dewwas 84 and 36% for the pure stands and mixtures, respectively. Although other mechanisms also were operative, reduced leaf wetness was likely a substantial contributor to panicle blast control in the mixtures. }, number={4}, journal={Phytopathology®}, publisher={Scientific Societies}, author={Zhu, You-Yong and Fang, Hui and Wang, Yun-Yue and Fan, Jin Xiang and Yang, Shi-Sheng and Mew, Twng Wah and Mundt, Christopher C.}, year={2005}, month={Apr}, pages={433–438} }
