The present studies were carried out to evaluate resistance in the populations of Fab. (Lepidoptera, Noctuidae) from five districts of Hunan Province in China to various insecticides from 2010 to 2012 using a standard leaf dip bioassay method. For organophosphates and pyrethroids, resistance ratios compared with a susceptible Lab-BJ strain were in the range of 14-229-fold for organophosphates and 12-227-fold for pyrethroids. Similarly, relative low levels of resistance to emamectin, indoxacarb, and chlorfenapyr were observed in all five populations. In contrast, the resistance to carbamates (thiodicarb or methomyl) was significantly higher than that of organophosphates, pyrethroids and newer chemistry insecticides. The pairwise correlation coefficients of LC values indicated that the newer chemistry insecticides and old generation insecticides were not significant except abamectin, which was negatively significantly correlated with methomyl. A significant correlation was observed between thiodicarb, methomyl, and deltamethrin, whereas resistance to bifenthrin showed no correlations with resistance to other insecticides except deltamethrin. The results are discussed in relation to integrated pest management for with special reference to management of field evolved resistance to insecticides.
本研究于2010年至2012年开展，采用标准浸叶生物测定法，评估中国湖南省五个地区的棉铃虫（鳞翅目，夜蛾科）种群对各种杀虫剂的抗性。对于有机磷类和拟除虫菊酯类杀虫剂，与敏感的Lab-BJ品系相比，有机磷类的抗性倍数在14至229倍之间，拟除虫菊酯类的抗性倍数在12至227倍之间。同样，在所有五个种群中均观察到对甲氨基阿维菌素苯甲酸盐、茚虫威和氯虫苯甲酰胺的相对较低水平的抗性。相比之下，对氨基甲酸酯类（硫双威或灭多威）的抗性显著高于有机磷类、拟除虫菊酯类和新型化学杀虫剂。LC值的成对相关系数表明，除阿维菌素与灭多威呈显著负相关外，新型化学杀虫剂与老一代杀虫剂之间无显著相关性。硫双威、灭多威和溴氰菊酯之间存在显著相关性，而联苯菊酯的抗性与除溴氰菊酯外的其他杀虫剂的抗性无相关性。结合害虫综合管理，特别是针对田间产生的抗药性管理，对结果进行了讨论。
