泽泻田莲纹夜蛾的诱集试验及田间药效试验初报

Trapping test and field trial of pesticide efficacy for Prodenia litura fabricius in Alisma orientale (Sam.) Juzep.field

摘要: 开展莲子与泽泻按1:9比例面积间栽的诱集试验,结果表明:莲子对莲纹夜蛾具有较强的诱集作用,且以太空莲36号品种诱集效果最好,其泽泻田间莲纹夜蛾的种群数量明显轻于对照。田间药效试验结果显示:15%安打SC、10%除尽SC这2种化学农药和2.5%菜喜SC、20%米满SC这2种生物农药对莲纹夜蛾幼虫都具有较高防效;99%绿颖OL作为一种对害虫无抗性风险的农药,是今后莲纹夜蛾综合治理的理想药剂。

Abstract: The trapping test of Lotus and Alisma orientale(Sam.)Juzep.intercrop by 1:9 area.The results showed that Lotus had stronger trapping effect on Prodenia litura fabricius,especially Outer Space Lotus 36,the population number of Prodenia litura fabricius decreased significantly,the field trial of pesticide efficacy showed chemical pesticides 15% Anda SC,10% Chejin SC and biological pesticides 2.5% Caixi SC,20% Miman SC,99% Lüying OL had higher prevent effect to Prodenia litura fabricius larva,99% Lüying OL was one kind of the no resistance risk pesticide to pest,it’s the ideal pesticide for Prodenia litura fabricius integrate control.
