摘要
[目的]利用性诱剂田间防治斜纹夜蛾,提高防效,减少农药使用,降低防治成本。[方法]在田间栽培的茄子、白菜、甜瓜、豇豆上挂设性诱剂防治斜纹夜蛾,统计诱杀量、虫口密度,比较防治效果,计算防治成本。[结果]在4种蔬菜上使用性诱剂平均防效比纯化学药剂防治分别提高22.0%、30.3%、33.2%、28.7%,用药量减少2/3,降低防治成本。[结论]利用性诱剂和化学药剂防治蔬菜斜纹夜蛾比纯化学药剂防效好。
[Objective] Sex lure was used to control Spodoptera litura so as to improve control efficiency,reduce control cost.[Method] Sex lure was hung on eggplant,cabbage,melon and cowpea cultivated in the field.Trapping capacity,population density,control effect and control costs were studied.[Result] The sex lure effect on average increased by 22.0%,30.3%,33.2%,28.7% on the four kinds of vegetables,and medication was reduced 2/3 of the amount.The control cost was reduced.[Conclusion] The effect of sex lure and chemical control of Spodoptera litura was better than that of the pure chemicals.
