黑腹果蝇是蓝莓果实转色成熟期的一种主要钻蛀性害虫,为害期长且难以防治。安徽农业大学植物保护学院等单位研究人员采用常规喷雾法,比较了60g/L乙基多杀菌素悬浮剂、10%溴氰虫酰胺可分散油悬浮剂、2.5%甲氨基阿维菌素乳油和0.3%苦参碱水剂等4种杀虫剂对蓝莓黑腹果蝇的防治效果。结果表明,60g/L乙基多杀菌素悬浮剂的防治效果最好,3000倍液施药后第1天、3天和7天对黑腹果蝇幼虫的防治效果分别为100.0%、96.1%和
Drosophila melanogaster is a major boring pest in the ripening stage of blueberry fruit, with long duration and difficult to control. Plant Protection College of Anhui Agricultural University and other units of researchers using conventional spray method, compared with 60g / L ethyl spinosyn suspension, 10% bromoxetane dispersible oil suspension, 2.5% EC avermectin EC and 0.3% matrine and other four kinds of pesticides on blueberry Drosophila control effect. The results showed that the control effect of 60g / L ethyl spinosyn SC was the best. The control effects on the larvae of Drosophila melanogaster on the 1st, 3rd and 7th day after spraying with 3000 times were 100.0%, 96.1% with
