摘　　要：以寒地稻田优势种蜘蛛拟水狼蛛为研究对象，分析生产上常用高效氯氰菊酯、吡虫啉、阿维菌素三种杀虫剂胁迫对拟水狼蛛的影响。结果表明，三种杀虫剂对稻田蜘蛛有较大杀伤力，总死亡率达35.44%~81.25%。三种杀虫剂处理后拟水狼蛛体内保护酶和解毒酶系含量均低于对照，说明杀虫剂胁迫下，蜘蛛抵抗能力及降解代谢能力下降，影响对害虫控制效果。In this study, Pirata subpiraticus was the dominant spider in cold rice field as the research objective. Beta cypermethrin, abamectin and imidacloprid were choosed to study the influence of insecticide stress to dominant species spider in cold rice field. The results showed that these insecticides had lethality to spiders in rice field. The mortality rate was 35.44%-81.25%.The protective enzymes content and detoxifying enzymes content of Pirata subpiraticus were lower than antitheses after treated by three kinds of insecticides.It illustrated that under insecticide stress, it influenced control effect of pests while the resistivity and metabolic degradation ability decreased.
