摘　　要：为科学有效地防治丹参新害虫--薄荷金叶甲,本文测定了5种化学药剂啶虫脒、噻虫嗪、阿维菌素、甲氨基阿维菌素苯甲酸盐、高效氯氰菊酯对丹参新害虫薄荷金叶甲的毒力效果。结果表明,所选5种化学药剂对薄荷金叶甲均有一定的毒力作用,但相互之间存在较大差异,其中,甲氨基阿维菌素苯甲酸盐的毒力最高,LC50值为1.7404mg/L,啶虫脒和高效氯氰菊酯的毒力相近,LC50值分别为64.7845和86.5744mg/L,而噻虫嗪对薄荷金叶甲的毒力较差,LC50值为220.2474 mg/L,阿维菌素对薄荷金叶甲的毒力最差,LC50值为678.6936mg/L。In order to control Chrysolina exanthematica Wiedemann,a new pest occurred in Salvia miltiorrhiza Bge fields effectively,the toxicities of the five chemical insecticides,including acetamiprid,thiamethoxam,abamectin,emamectin benzoate and beta cypermethrin were determined in laboratory.The results indicated that the toxicities of the five chemical insecticides varied greatly.Emamectin benzoate showed the best toxicity with LC50 of 1.7404 mg/L.The LC50 of acetamiprid and beta cypermethrin were 64.7845 mg/L and 86.5744 mg/L,respectively,which were close to each other.Thiamethoxam provided a relative low toxicity with LC50 of 220.2474 mg/L while abamectin showed the lowest toxicity among all the tested insecticides,with the highest LC50 of678.6936 mg/L.
