摘要
选择常规农药品种三唑磷、阿维菌素,对湖北省4个稻区的二化螟和三化螟虫于2005年至2007年连续进行了室内毒力测定。结果表明,监测地区水稻二化螟和三化螟对三唑磷及阿维菌素均产生了明显的抗药性,但抗药性水平和发展速度各地区之间有差异。这可能与各地栽培制度、用药水平等因素有关。
In this paper,the insecticide resistance level of rice stem borers （Chilo suppressalis Walker and Tryporyza incertulas Walker） from four cities were tested by using Triazophos and Avermectins every year since 2005. The results show that the pests have obvious insecticide resistance to Triazophos and Avermectins, which are very commonly used in four cities, and the level and the development speed of rice stem borer＇s insecticides resistance are discrepant among the four cities. The reasons maybe relate to insecticides application technology, planting habits, climate and so on.
