中文摘要: |
为筛选防治温室白粉虱的有效药剂, 采用室内和田间药效方法测定了7种杀虫剂在推荐剂量下对温室白粉虱卵、若虫和成虫的防治效果。结果表明:22%氟啶虫胺腈悬浮剂、1.8%阿维菌素乳油单用或22.4%螺虫乙酯悬浮剂和25%烯啶虫胺可溶性粉剂混用对卵和若虫的防效高达85%以上。10%氟啶虫酰胺水分散粒剂、22%氟啶虫胺腈悬浮剂对成虫的速效性和持效性最好, 防效均高达94%以上。因此, 推荐在温室白粉虱发生初期选择氟啶虫酰胺、氟啶虫胺腈、阿维菌素单用或螺虫乙酯和烯啶虫胺混用进行防治, 世代重叠严重时可根据对不同虫态的防治效果选择几种药剂混用。 |
英文摘要: |
In order to screen effective pesticides against the greenhouse whitefly Trialeurodes vaporariorum (Westwood), control efficacies of seven insecticides at recommended concentrations on eggs, nymphs and adults of T. vaporariorum were evaluated by indoor and field tests. The results showed that sulfoxaflor 22% SC, mixture of spirotetramat 22.4% SC and nitenpyram 25% SP, and abamectin 1.8% EC had the highest control efficacy to eggs and nymphs with values higher than 85%. For adults, the flonicamid 10% WG and sulfoxaflor 22% SC had the best control efficacy and persistent effect, with the control efficacy higher than 94%. Therefore, flonicamid, sulfoxaflor, nitenpyram, or mixture of spirotetramat and abamectin alone were recommended for control of T. vaporariorum during the early stage of the pest occurrence. When T. vaporariorum with multiple developmental stages occurred simultaneously in the field, the combined insecticides according to their performance were recommended for application |
