应用斜纹夜蛾性引诱技术,准确预测了发蛾高峰,诱杀大量雄蛾,对第三、四代斜纹夜蛾的虫口减退率分别为72.62%、84.4%,对夏阳白的保护效果达76.25%,与化学防治效果相当,只有防化区的1/3,有利降低食品中农药残留,提高蔬菜产品质量。实践证明,应用性引诱剂技术是控制蔬菜斜纹夜蛾危害的一种好方法,值得推广应用,前景广阔。
Applying the technique of sex attractant of Spodoptera litura, the peak of hair moths was accurately predicted, and a large number of male moths were trapped and killed. The rate of decrease in the population of the third and fourth generations of Spodoptera litura was 72.62% and 84.4%, respectively, , With the same chemical control effect, only one-third of the chemical resistance, beneficial to reduce pesticide residues in food, improve vegetable product quality. Practice has proved that the application of attractant technology is to control the harm of vegetable Spodoptera litura is a good way, it is worth promoting the application of broad prospects.
