7种杀虫剂对甘薯小绿龟甲的毒力及温度对啶虫脒毒力的影响

Toxicity of Seven Insecticides to Cassida Circumdata and Effect of Temperature on the Toxicity of Acetamiprid

采用浸叶法测定了7种杀虫剂对甘薯小绿龟甲成虫的毒力,结果表明,供试杀虫剂对甘薯小绿龟甲的毒力顺序依次为甲氨基阿维菌素苯甲酸盐>阿维菌素>多杀菌素>啶虫脒>氟虫腈>溴氰菊酯>敌敌畏。在15~35℃温度范围内,随着温度升高啶虫脒对甘薯小绿龟甲的毒力显著提高,表明该药剂属于正温度效应类型杀虫剂。

oxicity of seven insecticides to Cassida circumdata adults was determined by leaf dipping method in the laboratory.The results showed that the toxicity order of the insecticides was arranged as follows: emamectin benzoate > abamectin > spinosad > acetamiprid > fipronil > deltamethrin > dichlorvos.In the temperature range of 15 ~ 35℃,the toxicity of acetamiprid to C.circumdata improved with the increase of temperature,indicating that acetamiprid is a positive temperature effect insecticide.
