| 摘 要： | 采用滤纸药膜法研究了多杀菌素原药、阿维菌素精粉、蛇床子素粉剂对玉米象、谷蠹和锯谷盗的毒力,并与甲基嘧啶硫磷进行了毒力比较.结果表明:多杀菌素原药、阿维菌素精粉、蛇床子素粉剂和甲基嘧啶硫磷水乳剂对玉米象的LD50值分别为125.092μg/cm2、1 801.386μg/cm2、0.051μg/cm2和0.274μg/cm2,对谷蠹的LD50值分别为9.565μg/cm2、14.549μg/cm2、0.041μg/cm2和0.706μg/cm2,对锯谷盗的LD50值分别为24.557μg/cm2、55.501μg/cm2、0.050μg/cm2和0.185μg/cm2;多杀菌素和阿维菌素对3种害虫的毒力相当,多杀菌素和阿维菌素对3种害虫的毒力均小于甲基嘧啶硫磷,蛇床子素粉剂对3种害虫的毒力均高于甲基嘧啶硫磷至少3倍,且对谷蠹的毒力是甲基嘧啶硫磷的17倍多.
