白城市果树金龟子防治研究报告

Control Techniques Against Chafer Injurious to Fruit Tree in Baicheng City

金龟子对果树特别是幼龄果树为害相当严重,本项目对白城市幼龄果树所发生的黑绒鳃金龟子和东北大黑鳃金龟的危害及防治措施进行了研究,结果表明:采用生物防治方法可以有效降低虫口密度;采用六六六加敌敌畏按3∶1混合剂进行化学防治,防治效果达98.6%。

Chafer bored fruit trees, especially young fruit trees severely. Damage by Maladera orientalis and Holotrichia diomphalia on young fruit trees and their control techniques were studied. The results showed that larvae density was decreased effectively by using biological control techniques. Using concentration of benzene hexachloride（BHC） and dichlorvos（DDVP） by 3：1 , the control effect can reach 98.6%.
