棱角山矾虫害咖啡木蠹蛾的防治试验

Test of Controlling Zeuzea coffeae Nietiner in Symplocos tetragona

摘要: 咖啡木蠹蛾以幼虫为害棱角山矾的树干和枝条。为有效控制咖啡木蠹蛾的发生和蔓延，减少虫害所造成的经济损失，利用1.8%阿维菌素乳油、40%毒死蜱乳油、15%阿维·毒死蜱水乳剂进行防治咖啡木蠹蛾试验，结果表明：3种农药防治咖啡木蠹蛾的持效性均较好，其中1.8%阿维菌素乳油为生物杀虫剂，使用安全，是比较理想的生物农药，可在生产中可大面积推广。

Abstract: Larvae of Zeuzea coffeae Nietiner damages stems and branches of Symplocos tetragona. In order to control occurrence and spread of Zeuzea coffeae Nietiner effectively and reduce economic loss caused by insect damage, 1.8% Avermectin emulsifiable concentrate, 40% Chlorpyrifos emulsifiable concentrate and 15% abamectin·chlorifos emulsion in water were used to control Zeuzea coffeae Nietiner. The results showed that three chemicals had good persistence to control Zeuzea coffeae Nietiner. 1.8% Avermectin emulsifiable concentrate was a type of biological insecticide and could be used in safety, so it is an ideal biological pesticide and could be extended on a large scale in the production.
