摘　　要：【目的】结合生产实际,测定不同常用药剂对枣瘿蚊的田间防治效果,筛选出安全、高效的药剂,为合理防治该害虫提供科学指导。【方法】选择几种不同类型、不同作用方式的药剂,于枣瘿蚊幼虫发生第一代进行田间药效试验。【结果】在药后11 d,40%毒死蜱乳油、3.5%吡虫啉可湿性粉剂和5%高效氟氯氰菊酯乳油防效均达到80%以上,其次为20%啶虫脒可湿性粉剂防效也达70.12%。各处理药剂持效期均在11d左右。【结论】于枣瘿蚊幼虫发生高峰期,选用防效较高,持效期较长的40%毒死蜱乳油进行控制。其它时期可使用5%高效氟氯氰菊酯乳油、3.5%吡虫啉可湿性粉剂和20%啶虫脒可湿性粉剂进行交替使用。[ Objective]This project, in view of the actual production, aims to test the control effects of different pesticides against Contarinia sp. in order to screen out the safer and more effective medication and provide valuable scientific information for the rational control of the pests in practice. [ Method] Different types of pesticides and various dosages were tried in the experiment when the peak larvae of the first stage Contarinia sp. occurred. [ Result] From the field control efficiency experiments, it could be concluded that 40% Chlor- pyrifos EC, 3.5% imidacloprid WP and 5% bata - cyfluthrin EC had better control effect, reaching more than 80% after 11 days and the second better one was 20% acetamiprid WP, the control effect of which could reach 70.12%. The effective controlling time was about lldays. [ Conclusion] Dilution of 40% cglorpyrifos EC may be recommended for application in jujube orchard during the peak incidences of Contarinia sp. lar- vae. 3.5% imidacloprid WP, 5% bata - cyfluthrin EC and 20% acetamiprid WP can be applied alternately in other times.
