摘要：

为了及时了解兰溪市番茄温室主要害虫白粉虱对常规药剂的抗药性发展,同时筛选出高效、安全和低毒的温室白粉虱防控药剂。采用室内毒力测定法和大田试验,分别比较了8种药剂对温室白粉虱成虫的毒力和防效。8种供试杀虫剂对白粉虱成虫的毒力存在差异,其中25%烯啶虫胺可溶性粉剂(SP)对白粉虱成虫保持相对较高的毒力,其50%致死浓度(LC50)均值为1.58 mg·L-1;温室白粉虱成虫对22%噻虫啉水分散粒剂(WG)、1.3%苦参碱水剂(AS)杀虫剂不敏感,尤其是1.3%苦参碱AS,其LC50均值为75.92 mg·L-1。温室试验结果表明,25%烯啶虫胺SP、20%呋虫胺可湿性粉剂(WP)、70%吡虫啉WG和10%氟啶虫酰胺WG在药后7和14 d均表现出较好的防治效果。温室白粉虱成虫对不同杀虫剂的敏感性差异较大,结合室内毒力测定,25%烯啶虫胺SP、20%呋虫胺WP、70%吡虫啉WG和10%氟啶虫酰胺WG可作为兰溪市温室白粉虱的防治药剂。

Abstract:

To promptly understand the development of resistance in whitefly, a major pest in tomato greenhouses in Lanxi City, to conventional pesticides, and to screen for highly effective, safe, and low-toxicity pesticides for controlling greenhouse whiteflies, laboratory toxicity bioassays and field trials were conducted to compare the toxicity and control efficacy of eight pesticides against adult whitefly. The results revealed significant differences in toxicity among the tested pesticides. Among them, 25% nitenpyram SP maintained relatively high toxicity against adult whiteflies, with an average LC50 of 1.58 mg·L-1. In contrast, adult whitefly exhibited low sensitivity to 22% thiacloprid WG and 1.3% matrine AS, particularly the latter, which had an average LC50 of 75.92 mg·L-1. Field trial results demonstrated that 25% Nitenpyram SP, 20% dinotefuran WP, 70% imidacloprid WG, and 10% flonicamid WG all showed superior control efficacy at 7 and 14 days after application. Given the significant variation in the susceptibility of greenhouse whitefly adults to different pesticides and combined with laboratory toxicity data, 25% nitenpyram SP, 20% dinotefuran WP, 70% imidacloprid WG, and 10% flonicamid WG are recommended as effective pesticides for controlling whitefly in greenhouses in Lanxi City.
