| 摘 要： | 1984年研究了溴氰菊酯、氰戊菊酯和氯氰菊酯对棉蚜及其天敌异色瓢虫的影响,结果表明,氰戊菊酯对异色瓢虫的毒力较溴氰菊酯、氯氰菊酯及乐果为低。在瓢虫发生盛期,防治棉蚜宜使用氰戊菊酯。

| Abstract: | The effect of pyrethroids fenvalerate, cypermethrin, deltamethrin and Organic phosphate Insecticid dimethoate on the Aphis gossypii and its natural enemy, Leis axyridis was studied in 1984.Results show that the toxicity of fevalerate to the Leis axyridis is lower than those of cypernethrin, deltamethrin and dimethoate.During the Peak occurrence of Leis axyridis, the fevalerate is the best for controlling Aphis gossypii.The concentration of 30 PPm for fevalerate application is suitable. |
