Selective tools, including selective insecticides and transgenic cotton, have been crucial in reducing insecticide usage within the integrated pest management (IPM) plan for Arizona cotton. To guide growers effectively, cotton field trials evaluated the effects of the novel insecticides, isocycloseram and afidopyropen against our primary pests, Bemisia argentifolii and Lygus hesperus, and their impacts on nontarget arthropods, including key predators: Collops spp., Orius tristicolor, Geocoris spp., Misumenops celer, Drapetis nr. divergens and Chrysoperla carnea s.l. Assessments involved over 27 arthropod taxa through community analyses, individual predator abundance, and biological control function via predator to prey ratios and a sentinel prey method. Comparisons were made with an untreated check, a proven fully selective insecticide (flonicamid) and acephate-treated positive controls.
Overall, relative to the untreated check, afidopyropen showed no significant differences, whereas isocycloseram exhibited some negative impacts, primarily reducing M. celer and Geocoris spp. nymphs, yet it was less detrimental compared with the positive control, acephate, and it did not affect four of the six key predators and most nontarget arthropods.
Afidopyropen was classified as a fully selective insecticide and isocycloseram as a partially selective insecticide. Their fit for conservation biological control in Arizona cotton IPM and similar systems is discussed. © 2024 Society of Chemical Industry.
包括选择性杀虫剂和转基因棉花在内的选择性工具，在亚利桑那州棉花的综合虫害管理（IPM）计划中对于减少杀虫剂使用至关重要。为了有效地指导种植者，棉花田间试验评估了新型杀虫剂异环磷酰胺和氟啶虫胺腈对主要害虫银叶粉虱和西方盲蝽的效果，以及它们对非靶标节肢动物的影响，包括关键捕食者：隐翅虫属、三色小花蝽、地长蝽属、敏捷狡蛛、近分歧蚤蝇和普通草蛉。评估通过群落分析、个体捕食者丰度以及通过捕食者与猎物比例和哨兵猎物法的生物防治功能涉及超过27个节肢动物分类单元。与未处理对照、一种经过验证的完全选择性杀虫剂（氟吡菌酰胺）和乙酰甲胺磷处理的阳性对照进行了比较。
总体而言，相对于未处理对照，氟啶虫胺腈没有显著差异，而异环磷酰胺表现出一些负面影响，主要减少了敏捷狡蛛和地长蝽属若虫，但与阳性对照乙酰甲胺磷相比危害较小，并且它没有影响六个关键捕食者中的四个以及大多数非靶标节肢动物。
氟啶虫胺腈被归类为完全选择性杀虫剂，异环磷酰胺被归类为部分选择性杀虫剂。讨论了它们在亚利桑那州棉花IPM和类似系统中适用于保护生物防治的情况。© 2024化学工业协会。
