不同药剂对两点山钩蛾的毒力测定和防效试验

7种农药对两点山钩蛾室内毒力测定的结果表明:48%毒死蜱、2.5%溴氰菊酯、1%甲氨基阿维菌素、20%氯虫苯甲酰胺、Bt和20%虫酰肼6种农药之间的差异不显著,药后3 d的校正死亡率均在96%以上,而77.5%敌敌畏的毒力较差;野外防治试验表明:除敌敌畏外,6种农药药后7 d的校正防效均在96%以上。

Study on Toxicity Test and Control Effect of Different Pesticides

Seven kinds of Oreta bimaculata pesticides were studied. The result of toxicological test showed that the difference among 48% chlorpyfifos, 2. 5% Deltamethrin, 1% emamectin benzoate, 20% chlorantraniliprole, Bt, 20% tebufenozide was not significant. All of the adjusted mortality rate was more than 96% after 3 days and 77.5% dichlorphos was ineffectiveness. The result of field control test showed that except 77. 5% dichlorphos, the adjusted control effect of the other pesticides was more than 96% after 7 days.
