| 摘 要： | 采用微量点滴法，测定了毒死蜱、甲维盐、敌敌畏、顺式氯氰菊酯等4种杀虫剂对瓜实蝇成虫的毒力和二元混配的联合毒力。结果表明：80 %敌敌畏乳油（EC）的LD50最小，为1.683 9 μg?g-1|100 g?L-1顺式氯氰菊酯EC的LD50最大，为8.877 0 μg?g-1。供试杀虫剂毒性大小依次为：80 %敌敌畏EC＞5 %甲维盐微乳剂（ME）＞480 g?L-1毒死蜱EC＞100 g?L-1顺式氯氰菊酯EC。敌敌畏与甲维盐（1∶1）混配的增效作用最强，共毒系数为426。

| Abstract: | Four insecticides toxicities to adult of Bactrocera（Zeugodacus）cucurbitae（Coquillett）and their co-efficient ratio were determined by micro drop method．The results showed that LD50 of 80 % dichlorvos EC was minimum for 1.683 9 μg?g-1 and alpha-cypermethrin EC was the largest for 8.877 0 μg?g-1．The toxicity order was 80 % dichlorvos EC＞5 % emamectin-benzoate ME＞480 g?L-1 chlorpyrifos EC＞100 g?L-1 alpha-cypermethrin EC．The co-efficient ratio of the mixture of dichlorvos and emamectin-benzoate（1∶1）was 426． |
