5种杀虫剂对甜菜夜蛾的室内毒力与田间应用效果评价

通过室内毒力测定和田间药效试验，测定当前5种杀虫剂对甜菜夜蛾的防治效果。结果表明，10％溴虫腈EC对甜菜夜蛾具有优良的防效，药后7d防效为92．11％，可作为防治甜菜夜蛾的首选药剂；2．5％多杀菌素SC的效果次之．防效为85．49％：2％阿维菌素EC、4．5％高效氯氰菊酯EC和48％乐斯本EC防效稍差，在生产上应慎用。...

podoptera exigua Htibner; pesticide; toxicity test; control effect
The trial of 5 mainstream insecticides against Spodoptera exigua Htibner through the laboratory toxicity and field trials were studied. The results showed that the best choices in the Spodoptera exigua chemical control was 10% Chlorfenapyr EC. It showed a good efficiency to the best armyworm control with 92.11%. Then 2.5% Spinosad SC was a kind of insecticide which effect was not so well as 10% Chlorfenapyr with the armyworm control of 85.49%. However 2% Avermectins EC, 4.5% Beta cypermethrin EC and 48% Chlorpyrifos EC had poor effect in control of Spodoptera exigua,and should be used carefully.
