摘  要:
以豆蚜为供试虫源,采用室内毒力测定和田间药效试验方法,测定了6种药剂对豆蚜的敏感性。结果表明:供试豆蚜对74.6%甲氨基阿维菌素苯甲酸盐产生极高的抗性,当测试浓度达1 000mg/L时,24h校正死亡率仅为30.36%,对95%高效氯氰菊酯的敏感性最高,半数致死浓度(LC50)为8.1609mg/L。6种药剂对豆蚜的毒杀效果依次为:95%高效氯氰菊酯>95%毒死蜱>98%啶虫脒>94%阿维菌素>96%吡虫啉>74.6%甲氨基阿维菌素苯甲酸盐。田间试验结果表明:除甲氨基阿维菌素苯甲酸盐外,其余5种药剂均对豆蚜具有非常好的防效,施药后3、7d的防效均达99%以上。除74.6%甲氨基阿维菌素苯甲酸盐外,目前使用的多数药剂对豆蚜具有较好的防治效果。

摘  要:
Taking Aphis craccivora Koch as tested pest,the toxicity and field control efficacy of six insecticides to bean aphid Aphis craccivora Koch(Hemiptera:Aphididae)were studied.The toxicity test results showed that the bean aphid developed high resistance to 74.6% Emamectin benzoate with a mortality of 30.36% after 24hours under the concentration of 1 000mg/L.This aphid showed the highest sensitivity to 95% Beta-cypermethrin with a LC50 of 8.1609mg/L.The order of the toxicity of the six tested pesticides to the bean aphid from high to low was 95% Beta-cypermethrin,95% Chlorpyrifos,98% Acetamiprid,94% Abamectin,96% Imidacloprid and 74.6% Emamectin benzoate.The field experiments showed that the tested pesticides all had good control efficacy to the bean aphid with at least 99%control efficacy in 3and 7days except for Emamectin benzoate.Most of the presently used pesticides had high control efficacy to the bean aphid except for the 74.6% Emamectin benzoate.
