| 摘 要： | 室内浸叶法测定结果表明:广西不同小菜蛾种群对印楝素的敏感性差异较小,LC50值在0.07￣0.23mg/L之间,与敏感性最低的石埠种群相比,相对毒力指数为1￣3.29;对阿维菌素对的的敏感性差异较大,LC50值在2.08￣17.02mg/L之间,与敏感性最低的仁乡种群相比,相对毒力指数为1￣8.18。

| Abstract: | The result of laboratory testing showed that the P. xylostella (L) populations collected from different vegetable areas in Guangxi had little vioration in sensitivity to azadirachtin, the LC50 value were 0.07~0.23 mg/L, and the index of relative toxicity (IT) were 1~3.29 compared with the sensitive of Shibu population. But it produce different sensitive to avermectin by different populations collected from different vegetable areas in Guangxi Province, the LC50 value were 2.08~17.02 mg/L, and the index of relative toxicity (IT) were 1~8.18 compared with the sensitive of Renxiang population. |
