Application of an Impregnated Vial Bioassay for Rapid Field Detection of Insecticide Efficacy Against Scirtothrips dorsalis in Blueberry production

This study evaluated the use of an infield impregnated vial bioassay to assess the contact efficacy of six insecticides: cyantraniliprole, diazinon, imidacloprid, malathion, spinosad and zeta-cypermethrin. Field-collected females of Scirtothrips dorsalis were exposed to commercial formulations of each active ingredient for 0.33, 1, 2, 3, 4, 5, and 6 h. Dead and alive thrips were counted independently for each exposure time.本研究采用田间浸渍瓶生物测定法（infield impregnated vial bioassay），评估了6种杀虫剂的接触毒效，分别为氰虫酰胺（cyantraniliprole）、二嗪磷（diazinon）、吡虫啉（imidacloprid）、马拉硫磷（malathion）、多杀菌素（spinosad）及zeta-氯氰菊酯（zeta-cypermethrin）。研究人员将田间采集的茶黄蓟马（Scirtothrips dorsalis）雌成虫暴露于各有效成分的商品制剂中，设置的暴露时长为0.33、1、2、3、4、5及6小时。针对每个暴露时长，分别统计死亡与存活的蓟马个体数量。
