摘要 [目的]筛选枣瘿蚊的防治药剂。[方法]通过田间小区试验比较了9种杀虫剂对枣瘿蚊的防治效果。[结果]9种药剂对枣瘿蚊防治效果均有较长的持效期,其中240 g/L螺虫乙酯悬浮剂6 000倍稀释液、25%噻虫嗪水分散粒剂7 000倍稀释液具有较好的速效性和持效性,药后3、7、11 d防效均在84%以上;1%甲维盐水剂、2.5%高效氯氟氰菊酯乳油、100 g/L乙虫腈悬浮剂、5%噻螨酮乳油、240 g/L氟啶虫胺腈悬浮剂防治枣瘿蚊速效性较差,3 d后药效均低于70%。[结论]防治枣瘿蚊为害嫩叶,240 g/L螺虫乙酯悬浮剂6 000倍稀释液、25%噻虫嗪水分散粒剂7 000倍稀释液、48%毒死蜱乳油1 500倍稀释液均对枣瘿蚊具有较稳定的防效。

Abstract [Objective] The aim was to screen out good pesticides to control Contaria sp.. [Method] Control effects of nine different kinds of pesticides against Contaria sp. were compared through field plot experiment. [Result] The nine different kinds of pesticides all had longer persistent period to control Contaria sp., among them the 6 000 times solution of 240 g/L spirotetramat SC and the 7 000 times solution of 25% thiamethoxam WG had good rapidly available and persistent period, and the control effects of them were more than 84% in 3, 7 and 11 days after treatment. 1% emamectin benzoate-chlorfenapyr AS, 2.5% beta-cyfluthrin EC, 100 g/L ethiprole SC, 5% hexythiazox EC and 240 g/L sulfoxaflor SC were not rapidly available to control Contaria sp., and all the control effects were below 70% in three days after treatment. [Conclusion] The 6 000 times solution of 240 g/L spirotetramat SC, the 7 000 times solution of 25% thiamethoxam WG and the 1 500 times solution of 48% chlorpyrifos EC have stable control effects to Contaria sp..

枣瘿蚊(Contaria sp.)俗称卷叶蛆、枣芽蛆、枣蛆、枣叶蛆,属双翅目瘿蚊科[1],分布于新疆、河北、陕西、山东、山西、河南等各地枣产区。幼虫严重为害嫩叶、花蕾、幼果,给枣树生产造成严重损失。近年来随着枣树栽培面积的扩大,枣瘿蚊在我国许多地区都有逐年加重趋势,因发生早、代数多、为害期长,枣瘿蚊已成为枣树生产较难防治的重要害虫之一[2]。笔者针对近年来国内外杀虫剂种类的变化,研究了不同类型的9种杀虫剂对枣瘿蚊的防治效果,旨在为枣瘿蚊防治提供参考。
