摘　　要：介绍了昆虫性信息素的作用原理与使用方法,研究了斜纹夜蛾、甜菜夜蛾、小菜蛾蔬菜三大害虫性信息素的应用效果,为昆虫性信息素的大面积推广应用提供了科学依据和技术支撑。试验结果表明,性信息素对斜纹夜蛾等害虫具有很好的诱杀作用,在成虫羽化期间可诱杀大量雄蛾,导致田间雌雄比例失调,有效减少了雌雄之间的交配行为,降低了成虫的自然交配率,造成下一代虫口密度大幅度下降。The action principles and usage methods of insect sex pheromones were introduced, and the effects of insect sex pheromones in controlling the three major vegetables pests, cotton leafworm Prodenia litura （Fabricius）, beet armyworm Spodoptera exigua （Hubner） and diamond-back moth PluteUa xylosteUa （Linnaeus） were studied. It provided scientific basis and technical support for the extension and application of insect sex pheromones. The results showed that the insect sex pheromones were effective to lure and kill pests; large quantity adults were killed in the whole period of emergence and result in the disproportion of female/male. At the same time, the mating behaviors reduced effectively, the natural mate rate of moths reduced. It leaded to the significant decline of offspring insect density.
