吡虫啉等6种杀虫剂对河北省不同地区绿盲蝽的室内毒力

Laboratory Toxicity of Six Insecticides toApolygus lucorμmin Different Regions of Hebei Province

采用叶片浸渍法,测定了吡虫啉、氟虫腈、高效氯氟氰菊酯、丁硫克百威、马拉硫磷和辛硫磷6种杀虫剂对河北省不同地区绿盲蝽种群的室内毒力效果。结果表明:氟虫腈对河北省绿盲蝽毒力最高,高效氯氟氰菊酯和丁硫克百威次之,马拉硫磷、辛硫磷和吡虫啉毒力较低;河北省不同地区绿盲蝽种群对药剂敏感性的差异较小,其中保定地区绿盲蝽种群对各药剂的敏感性最高。

The laboratory toxicity of six insecticides to Apolygus lucorμm in different regions of Hebei Province was determined by dipping method.The results showed that the toxicity of fipronil was the highest,that of lambda-cyfluthrin and carbosulfan took the second place,and that of malathion,phoxim and imidacloprid were lower.There were little differences among the sensitivity of A.lucorμm to insecticides in different regions of Hebei,and which was the highest in Baoding.
