田间试验示范结果显示,性诱迷向复合植物诱源黄板的综合治理新技术比单用性诱迷向技术防治效果提高2倍以上,植物诱源黄板诱杀效果是普通黄板诱杀效果的3.3倍;性诱迷向复合植物诱源黄板效果是普通黄板诱杀效果的7倍以上。3种不同诱捕密度示范结果也显示,当控害诱捕设置密度为60 m2左右时,治理效果与化学防治相近,且成本低,便于农户操作,还可延缓小菜蛾的抗药性。 The results of field experiments showed that the new technology of comprehensive treatment of lure yellow board induced by lure to plants was more than 2 times higher than that of lure alone technology, and the trapping effect of plant lure yellow board was the effect of common yellow board trapping 3.3 times; sexual attraction to the compound plant induced yellow board effect is more than 7 times the ordinary yellow board trapping effect. The results of the three kinds of different trap density also showed that when the control trap density was about 60 m2, the treatment effect was similar to chemical control, and the cost was low, which was convenient for peasant households to operate and delay the resistance of diamondback moth to insecticide resistance.
