五种杀虫剂对芦笋十四点负泥虫的毒力测定

Toxicity Determination to Crioceris Quatuordecimpunctata(Scopolic) of Five Insecticides

在室内条件下采用微量点滴法测定了5种杀虫剂对芦笋十四点负泥虫成虫的毒力.结果表明:供试杀虫剂对芦笋十四点负泥虫成虫的毒力大小顺序为毒死蜱、辛硫磷、阿维菌素、敌百虫、高效氯氰菊酯.通辽地区的芦笋十四点负泥虫成虫对毒死蜱和辛硫磷敏感性较高,而对阿维菌素、敌百虫和高效氯氢菊酯的敏感性较低.

The result of toxicity determination of five insecticides to Crioceris quatuordecimpunctata （Scopolic） from Tongliao indicated chlorpyifos and phoxim had high sensitivities. And the sensitivities of avennectin, trichborphou and beta - cypermethrin to it were low.
