摘要

摘要: 分别测定定了0.3%印楝素乳油、蜡蚧轮枝菌对天敌胡瓜钝绥螨的毒性．施药后10d 的观察结果,0.3%印楝素乳油直接喷于胡瓜钝绥螨虫体时毒性很小,药后10d的 LC50为5.01mg·L-1,回归线性方程 y=1.2294x+0.5260;胡瓜钝绥螨取食用0.3%印楝素乳油处理过的柑桔全爪螨则无中毒表现,即无毒性;蜡蚧轮枝菌对胡瓜钝绥螨寄生率为0,基本无毒性,故释放胡瓜钝绥螨生防园可采用0.3%印楝素乳油和蜡蚧轮枝菌防治茶小绿叶蝉、柑桔害螨、柑桔粉虱、蚧壳虫、蚜虫等害虫,既能有很好的防效又能保护天敌胡瓜钝绥螨。

Abstract: The toxicity of 0.3% Azadirachtin emulsion comentration and Verticillium lecanii to Amblyseius cucumeris Oudemans were tested.The results showed that 0.3% Azadirachtin emulsion comentration had some toxicity to Amblsyseius cucumeris Oudemans.The LC50 to Amblyseius cucumeris Oudemans was 5.01 mg·L-1 regression linear equation was y=1.2294x+0.526.But it showed no toxicity to Amblyseius cucumeris Oudemans after Amblyseius cucumeris Oudemans eat the citrus spider mite that were treated by 0.3% Azadiraehtin.And Verticillium lecanii also had no toxicity to Amblyseius cucumeris Oudemans.So adopting 0.3% Azadirachtin and Verticillium lecanii to control green leaf hopper,citrus pest mite,citrus white fly.citrus scale,aphid and other pests.not only acquirc better control effects but also protect the natural enemies—Amblyseius cucmeris Oudemans.
