摘要
采用点滴法测定了七星瓢虫4龄幼虫对17种杀虫剂的敏感性,其中有机磷类杀虫剂5种,拟除虫菊酯类杀虫剂6种,其他类杀虫剂6种。结果表明,七星瓢虫4龄幼虫对有机磷类5种杀虫剂的敏感性依次为三唑磷>辛硫磷>毒死蜱>乙酰甲胺磷>敌百虫;对拟除虫菊酯类杀虫剂的敏感性依次为甲氰菊酯>高效氯氟氰菊酯>高效氯氰菊酯>溴氰菊酯>醚菊酯>氰戊菊酯;对其他6种杀虫剂的敏感性依次为吡虫啉>氟虫腈>阿维菌素>甲氨基阿维菌素苯甲酸盐>杀螟丹>抗蚜威。总体而言,七星瓢虫对乙酰甲胺磷、敌百虫、醚菊酯、氰戊菊酯、甲氨基阿维菌素苯甲酸盐、杀螟丹、抗蚜威等7种杀虫剂的敏感性较低,对另外10种杀虫剂的敏感性较高。
The authors measured sensitivity of the 4th instar larvae of Coccinella septempunctata L.to 17 kinds of insecticides by drop method.Five kinds of organic phosphorus insecticides,six kinds of synthetic pyrethroid insecticides and other six kinds of insecticides have been measured.The results showed that the sensitivity sequence of the 4th instar larvae of Coccinella septempunctata to five kinds of organophosphate insecticides were triazophos 〉 phoxim 〉 chlorpyrifos 〉 acephate 〉 trichlorfon.The sensitivity sequence of the synthetic pyrethroid insecticides were fenpropathrin 〉 lambda-cyhalothrin 〉 beta-cypermethrin 〉 deltamethrin 〉 etofenprox 〉 fenvalerate. The sensitivity sequence of the other six kinds of insecticides were imidacloprid 〉 fipronil 〉 avermectin 〉 emamectin-benzoate 〉 cartap 〉 pirimicarb. Overall, the sensitivity of Coccinella septempunctata to acephate, trichlorfon, etofenprox, fenvalerate, emamectin- benzoate, cartap, pirimicarb were lower. The other 10 kinds of insecticides had higher sensitivity.
