摘要
调查了温室种植黄瓜生长期的温室白粉虱的发生情况,并筛选出了温室白粉虱的防治药剂,结果表明:1)从3月初至6月底,温室白粉虱虫口基数从5只上升至50只,至6月5号达到最高值,为50只,其后趋于平稳;2)阿维菌素、溴氰菊酯、吡虫啉、甲胺基阿维菌素几种药剂相比,溴氰菊酯对温室白粉虱的防治效果较高,药后1d防效为90%,药后3 d防效为81%,药后7 d防效为60%。
The study explores the dynamics of greenhouse whiteflies on cucumber planted in the greenhouse and selects the chemicals used to control the greenhouse whiteflies. The results show that from early March to the end of June, the population density of whiteflies grows from 5 to 50 and reaches the top of 50 on June 5th, then becomes stable gradually. Different chemi- cals are used to control greenhouse whiteflies. Compared with avermectin, imidacloprid, e- mamectin benzoate, deltamethrin has a higher effect on greenhouse whiteflies. After 1 day of chemical control, its effect is 90%; after 3 days of chemical control, its effect is 81%. after 7 days of chemical control, its effect is 60%.
