为探明吡虫啉和丁硫克百威防治水稻稻水象甲的适用性，采用稻种拌种处理，研究2种药剂对水稻稻水象甲的防控效果。结果表明：室内毒力测定，吡虫啉和丁硫克百威各处理苗饲养成虫24 h后均表现中毒现象，其中，2种药剂处理剂量为30 g/kg，处理120 h时虫口减退率分别为70．0％和58．33％。大田育苗移栽，2种药剂各处理对幼虫的防控作用好于成虫，其中，2种药剂处理剂量为30 g/kg时对幼虫和成虫的防效分别为98．69％和66．38％、94．08％和42．13％。2种药剂均可防治稻水象甲，吡虫啉的平均防效优于丁硫克百威，吡虫啉和丁硫克百威的推荐拌种剂量分别为25～30 g/kg和30～50 g/kg。

In order to explore the adaptability of imidacloprid and carbosulfan on controlling rice water weevil,the control effects were studied through seed dressing.Results:Intoxicating phenomenon occurred in all treatments after raising for 24 hours.The population reduce rate was respectively 70.0% and 58.33% after treated with imidacloprid and carbosulfan(30 g/kg)for 120 hours.The control effects of imidacloprid and carbosulfan on larvae were better than on adults,the control effects of imidacloprid and carbosulfan on larvae and adults were respectively 98.69% and 66.38%,94.08% and 42.13%.The two pesticides could all control rice water weevil,the average control effect of imidacloprid was better than carbosulfan,the recommended seed dressing doses was respectively 25~30 g/kg and 30~50 g/kg.
