Resistance Monitoring of Rice Stem Borer ( Chilo suppressalis Walker) to chlorpyrifos and chlorantraniliprole
Abstract：The rice stem borer，Chilo suppressalis（Walker）（Lepidoptera: Pyralidae） is an important pest in the rice fields around the world. It can damage the rice, which causes the symptoms such as dead sheath, dead heart, white paddy, withered pregnant ear and so on. For a long time, chemical control kept to be a major strategy for controlling the rice stem borer. As the result of over applying the chemicals, insecticide resistance of C. suppressalis has been an important problem. In this study, we detected the resistance of field populations from 7 province to two chlorpyrifos and chlorantraniliprole. The results showed that the highest resistance to chlorpyrifos was Zhejiang XS16 population (RR=35 folds), the highest resistance to chlorantraniliprole was found in Zhejiang province, CN16, YY16, XS16 populations were the most resistant, the highest resistance showed in Cangnan population reaching 74 times. This study is great significance to demonstrate the resistance of chlorpyrifos and chlorantraniliprole and helpful to design the strategy on resistance management.

水稻二化螟对毒死蜱和氯虫苯甲酰胺的抗药性监测
引言
二化螟是我国水稻上的重要害虫，除主要危害水稻外,还危害很多禾本科，在水稻上长形成枯稍、枯心、枯孕穗和虫伤株等受害症状，还可转株为害，严重影响水稻产量（罗南清，2006；吕锐玲，2011）。二化螟分布范围很广，我国主要稻区均有发生，尤其是长江流域发生频率颇高；国外遍及亚洲、大洋洲、北非及南欧的许多国家（盛承发等，2003）。我国稻螟灾害最早的记录始于乾隆元年，此后螟灾记录渐多。20世纪90年代以来螟灾达到历史最高水平，此后连年爆发成灾（盛承发等，2003）。
