The corn earworm, Helicoverpa zea (Boddie), is a major pest targeted by pyramided Bacillus thuringiensis (Bt) and cotton in the U.S. Cry1Ab one of first insecticidal toxins used Bt crops, while Vip3A relatively new toxin that has recently been incorporated into Cry with event MIR 162 varieties to generate traits targeting lepidopteran pests including H. zea. objectives this study were determine current status distribution resistance, evaluate susceptibility Vip3Aa20 expressed southeastern...
Abstract Bemisia tabaci Middle East-Asia Minor 1 (MEAM1) is a significant pest that damages wide range of high-value vegetable crops in south Florida. This has demonstrated the ability to develop resistance various insecticide groups worldwide. Monitoring levels MEAM1 populations and maintaining baseline susceptibility data are crucial for long-term effectiveness management strategies. We conducted serial dilution bioassays on 15 field collected Florida assess their 4 key insecticides:...
The corn earworm/bollworm, Helicoverpa zea (Boddie), is a pest species that targeted by both Bacillus thuringiensis (Bt) maize and cotton in the United States. Cry1Ab Vip3Aa20 are two common Bt toxins expressed transgenic maize. objective of this study was to determine resistance allele frequency (RAF) H. populations were collected during 2018 2019 from four southeastern U.S. states: Louisiana, Mississippi, Georgia, South Carolina. By using group-mating approach, 104 F2 iso-lines established...
One of the most destructive invasive pests worldwide is whitefly, Bemisia tabaci MEAM1. The Florida vegetable crop market, worth millions dollars annually, suffers major losses because whitefly injury. Spirotetramat frequently used by growers to control nymphs. A previous study based on maximum dose bioassays indicated that MEAM1 populations in may be developing resistance spirotetramat. Thus, long-term efficacy this active ingredient depends development baseline susceptibility data and...
The sweetpotato whitefly, Bemisia tabaci MEAM1, is a pest known to significantly impact tomato development and yields through direct damage virus transmission. To manage this pest, the current study compared effectiveness of various insecticide rotations. Field trials included rotations involving synthetic insecticides, biochemicals, microbial agents, applied according their labeled highest concentrations. Results indicated that while standard insecticides consistently reduced whitefly egg...
Abstract A seed blend refuge has been implemented in the U.S. Corn Belt for Bt maize resistance management. The fall armyworm, Spodoptera frugiperda (J.E. Smith), is a target pest of Americas. larvae this are mobile, which may affect efficacy refuges. In study, field and greenhouse trials were conducted to determine performance Bt‐susceptible (aabb) ‐heterozygous dual‐gene‐resistant (AaBb) genotypes S. blends non‐Bt pyramided maize. Three evaluated larval survival, growth, plant injury with...
Solutions for managing the growing populations of snail Bulimulus bonariensis (Rafinesque, 1833) in row crops, notably peanut ( Arachis hypogaea L.), are urgently needed United States. This species has become a concern to economy and food security infesting commercial crops U.S. southern states. In present study, sampling, trapping, management strategies were investigated support program B. crops. addition, preference weeds, used as shelter, dispersal capacity documented. The results...
The sweetpotato whitefly,
The corn earworm/bollworm, Helicoverpa zea (Boddie), in the United States is targeted by transgenic and cotton expressing Bacillus thuringensis (Bt) proteins. Previous studies have shown that resistance to Cry1A/Cry2A Bt has occurred field. In this study, we established 103 F2 isolines mass-mating of H. populations collected during 2018 2019 four southeastern U.S. states: Louisiana, Mississippi, Georgia, South Carolina. Dissection mated females showed at least 92.7% were originated from...
