摘　　要：蔬菜田小区试验比较了11种杀虫(螨)剂对蔬菜叶螨的防治效果。结果表明,3种专一性杀螨剂哒螨灵、克螨特、噻螨酮及6种广谱性杀虫杀螨剂阿维菌素、虫螨腈、高效氟氯氰菊酯、甲维盐、氧苦.内脂和螺螨酯对叶螨均有良好的防治效果,彼此之间差异不显著。其中低毒药剂克螨特、噻螨酮、阿维菌素和甲维盐的防治效果最佳,药后3、7、10d的防效分别达到79.96%、88.50%和99.01%(克螨特),82.64%、88.79%和97.77%(噻螨酮),73.24%、91.16%和97.73%(阿维菌素),74.12%、87.46%和98.62%(甲维盐),适合用于蔬菜叶螨的防治。高效氟氯氰菊酯属中等毒性,而螺螨酯防治效果稍低,使用时间和剂量应有所限制。而氯虫苯甲酰胺和多杀菌素对叶螨没有防治效果。The control effects of 11 insecticides against vegetable spider mites were compared in the field.The results showed that 3 acaricides,pyridaben,propargite,hexythiazox and 6 insecticides,abamectin,chlorfenapyr,cyhalothrin,emamectin benzoate,oxymatrine prosuler,envidor had good control effects and there was no significant difference among them.It had excellent control effects for 4 low-toxicity insecticides including propargite,hexythiazox,abamectin,and emamectin benzoate.Their control effects reached 79.96 %,88.50 % and 99.01 % for propargite,82.64 %,88.79 % and 97.77 % for hexythiazox,73.24 %,91.16 % and 97.73 % for abamectin,74.12 %,87.46 % and 98.62 % for emamectin benzoate after insecticides spray for 3,7,and 10 days respectively and they are proper for the control of vegetable spider mites.Cyhalothrin had middle toxicity and envidor showed lower control effects,so the timing and dose of their usage should be limited.However,chlorantraniliprole and spinosad didn’t exhibit any control effects for the spider mites.
