几种杀虫剂及其混配对瓜实蝇成虫的毒力测定
Toxicity Determination of Several Insecticides and Their Mixtures to Bactrocera (Zeugodacus) cucurbitae ( Coquillett)
摘要
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.关键词
