以“贵长”猕猴桃(Actinidia sinensis)为试材,采用喷雾法,研究了4种药剂对透翅蛾防治效果。同时,在2013—2014年调查了透翅蛾的生活史与为害特点。结果表明:在5—6月,采用2.5%高效氯氟氰菊酯EC 2 000倍液喷雾,药后7、14d对透翅蛾成虫防效分别为86.03%、92.98%;在6月至翌年3月,采用480g·L~(-1)毒死蜱EC 1 500倍液注入虫孔,药后14d对透翅蛾的校正防效为95.62%;在4—5月,采用棉球蘸480g·L~(-1)毒死蜱EC 1 500倍液堵住虫孔熏杀虫蛹,药后7、14d的防效均达90%以上,可有效控制该虫害。
Actinidia sinensis was used as test material to study the control effect of four kinds of medicament on pest moth. In the meantime, the life history and pest damage characteristics of Weevil moths were investigated in 2013-2014. The results showed that the control efficacy of 2.5% lambda-cyhalothrin EC 2 000 times spray from May to June was 86.03% and 92.98% respectively on the 7th and 14th day after treatment. From June to the next year In March, the control group was treated with 480 g · L -1 of chlorpyrifos EC 1 500 times, and the corrected control efficacy was 95.62% on the 14th day after treatment. The cotton ball dipped 480g · L ~ (-1) chlorpyrifos EC 1 500 times blocking the hole smoked insects and pupae, 7,14 d after drug control effect of more than 90%, which can effectively control the pest.
