摘要
测定了陕西省大荔、渭南、三原和杨陵４县（区）棉铃虫对溴氰菊酯、氰戊菊酯、氯氰菊酯及三氟氯氰菊酯和甲氰菊酯的抗药性。结果表明，各地棉铃虫对溴氰菊酯已产生了中等到高等程度抗药性，其抗性倍数为２９～５１倍；对氰戊菊酯处于耐药性到低等抗性阶段，其抗性倍数为３～７倍；对氯氰菊酯、三氟氯氰菊酯和甲氰菊酯尚未产生明显抗药性。因各地用药习惯、种类和水平不同，导致其种群间的敏感度存在一定差异。
The insecticide resistibility of cotton bollworm(Heliothis armigera)todecamethrin,fenvalerate,cypermethrin,cyhalothrin and fenpropathrin was determined inDali County,Sanyuan County,Weinan County and Yangling District of ShaanxiProvince. The results of the bioassay showed that the cotton bollworm from these fourplaces had a moderate to high level resistance to decpoethrin (about 29～51 timeshigh-er than susceptible ones)and had a tolerance to low resistance to fenvalerate about 3～7times higher than susceptible ones),while its resistance to cypermethrin and cyhalothrinwas still quite low. There existed a susceptibility difference in the determined areas dueto different ways ,kinds and doses of chemical application
