摘要：

为选择防治豆蚜的高效药剂，在室内条件下采用浸渍法测定了11 种常用杀虫剂对豆蚜的毒力大小。结果表明，24 h后对豆蚜活性较高的药剂为新烟碱类和拟除虫菊酯类杀虫剂，其中吡虫啉对豆蚜的毒力最高，致死中浓度（LC50）值为0.247 mg/L；其次为高效氯氰菊酯、阿维菌素和毒死蜱，LC50值分别为0.262、0.381、0.386 mg/L；吡蚜酮毒力最低，LC50值为35.710 mg/L。

AbstractIn order to screen the efficient insecticides for controlling Aphis craccivora Koch， the toxicities of eleven insecticides against A. craccivora were measured by dipping method. The results showed that neonicotinoid insecticides and pyrethoid insecticides had the best activity to A. craccivora after 24 hours. Imidacloprid had the highest toxicity and its LC50 value was 0.247 mg/L. The next were beta-cypermethrin， abamectin and chloprpyrifos and their LC50 values were 0.262， 0.381，0.386 mg/L， respectively. Pymetrozine had the lowest toxicity with the LC50value of 35.710 mg/L. KeywordsAphis craccivora Koch； Insecticides； Toxicity； Median lethal concentration （LC50）； Dipping method

豆蚜（Aphis craccivora Koch）属同翅目，蚜科，别名苜蓿蚜、花生蚜、槐蚜，主要为害大豆、菜豆、豇豆、豌豆、蚕豆等豆科作物，分布世界各地近100个国家[1]。豆蚜不仅吸取植物汁液，分泌蜜露，影响光合作用，还传播40余种植物病毒病，严重影响豆科作物质量和产
