摘要
[目的]为探明新疆北部棉区棉蚜种群对市场上和生产中常用药剂的敏感性程度。[方法]采用滤纸药膜法分别测定了147团和新湖农场棉蚜种群对4大类杀虫剂中的12种常用药剂的敏感性。[结果]2个棉蚜种群对同类杀虫剂的敏感度基本一致,对不同杀虫剂敏感性有较大差异。对吡虫啉、噻虫嗪、阿维菌素敏感性高,对菊酯类和有机磷类药剂敏感性低。[结论]根据测定结果,生产中应严格控制用药种类以及施药量和施药次数,选用不同类型杀虫剂轮用或混用,以延缓棉蚜抗性发展。
This experiments aimed to clear the sensitivity of cotton aphid in northern Xinjiang to insecticides used commonly in production and market.[Methods] The sensitivity of cotton aphid collected from 147 farm and Xinhu farm population were determined to twelve insecticides of four types by filter paper diffusion method respectively.[Results] The results showed that the sensitivity of two cotton aphid populations was the same to insecticides with the same type,and different to different types of insecticides,and high sensitivity to imidacloprid,thiamethoxam,avermectin,and lower sensitivity to pyrethroid and organophosphorus compounds.[Conclusions] According to the results,insecticide types,dosages and application frequency should be controlled strictly,in order to delay the resistance development of cotton aphid,and different insecticides should be applied alternately and mixed reasonably.
