摘要
采有浸渍法测定阿维菌素 ,吡虫啉及其混剂对菜蚜的毒力 ,阿维菌素与吡虫啉混配 ,各个配比均有增效作用 ,其中以 LC50 剂量 1:8的配比增效作用最大 ,毒性比率和共毒系数分别为 1.82和 194 .2 0。阿维菌素与吡虫啉的混剂对菜蚜有较好的防治效果 。
The test to determine the toxicological effect of abamectin, imidacloprid and their mixtures on vegetable aphid was performed using immersion method All mix-proportions at the dosage of LC50 had remarkable synergetic effect and 1:8 was the most remarkable Its index of relative toxicity and co-toxicity coefficient were 1 82 and 194 20 respectively The the mixture gave better control effect against vegetable aphid The results gotten indoors have been tested in the field
