摘要
应用浸叶饲喂法测定6种药剂对褐足角胸叶甲(Basilepta fulvipes Motschulsky)成虫的毒力作用。结果表明:6种杀虫剂均对褐足角胸叶甲均有效果,其中25%联苯菊酯.啶虫脒.哒螨灵乳油、25%氯虫苯甲酰胺.啶虫脒.哒螨灵乳油、25%除尽.啶虫脒.哒螨灵乳油和25%多杀菌素.啶虫脒.哒螨灵乳油对褐足角胸叶甲成虫的毒力较高,LC50分别为23.519 8、7.432 3、23.602 6和15.977 7 mg/L。45%马拉硫磷乳油和20%甲氰菊酯乳油的毒力较低。
By the immerse leaf feeding method, toxicity test results of 6 pesticides indicated that they can control B. fulvipes, 25% bifenthrin acetamiprid pyridaben EC, 25% chlorantraniliprole acetamiprid pyridaben EC, 25% chlorfenapyr acetamiprid pyridaben EC, 25% Spinosad acetamiprid pyridaben EC had better insectical activities against Basileptafulvipes Motschulsky, and LC50 values were 23.519 8 mg/L, 7.432 3 mg/L, 23.602 6 mg/L and 15.977 7 mg/L, respectively. 45% Fenpropathrin EC and 20% Fenpr-opathrin EC had lower insectical activities.
