摘要
对湖北省当阳市大蒜根蛆的发生规律、不同品种的抗虫性及药剂防治进行了调查试验。结果表明,大蒜根蛆在湖北1年发生2代,第1代根蛆危害时期为9月8～26日,第2代为9月25日至10月20日,第2代根蛆发生量大,危害严重;不同大蒜品种根蛆危害差异不大;药剂防治以10%地友GR处理土壤防效较好,为88.8%,叶面喷雾以2.5%肯打EC防效较好,为77.7%。
The bionomic and control of Delia antiqua （Meigen） in garlic in Dangyang county of Hubei province resistance of different garlic cuhivars to this insect were systematically investigated. The results showed that there generations of D. antiqua per year in Hubei province： the first generation occurred from 8 to 25 September, w second generation arose from 25 September to 20 October. The second generation caused the most serious damage The result from 11 garlic cuhivars indicated that no significant differences in resistance to this insect pest. In treatments, 10% Diazinon GR had the highest control efficacy,88.8%. Moreover, among three leaf treatments, the most efficacious was 2.5% Lambda-cyhalothtin EC, control efficacy was 77.7%.
