从理论上阐述了昆虫的化学通讯方式和昆虫性息素的生物学特性,二化螟性诱剂的成份,结构及其原理。从实践上开展了二化螟性诱剂的诱捕技术和应用效果研究,并进行了大面积试验示范。结果表明:采用水盆式诱捕器简单方便,对二化螟雄蛾具有很好的诱杀作用,成虫羽化期间的盆中日诱蛾量可明显反映出田间虫量。由于诱杀了大量雄蛾,导致田间雌雄比例失调,降低了成虫自然交配率,有效减少了子代虫口密度和危害程度,其诱控效果一般为70.0%~80.0%,与杀虫灯或一般药剂的防效相当,该项技术在二化螟中等或偏轻发生年份可大面积推广应用。
The chemical communication mechanism of insects and the biological characteristics of insect pheromone were elucidated in theory. The composition, structure and principle of sex insecticide were studied. Trapping techniques and application effects of the sex-attractant for the rice stem borer (Chilo suppressalis) were carried out in practice, and large-scale experiments and demonstrations were carried out. The results showed that the water trap was simple and convenient, and had a good trapping and killing effect on the two rice borer moths. The amount of the induced traps in the pots during the emergence period of adults could clearly reflect the amount of insect pests in the fields. As a result of trapping a large number of male moths, resulting in the field of male and female imbalance, reducing the rate of natural mating of adults and effectively reduce the population offspring density and degree of harm, the induction effect is generally 70.0% to 80.0%, and insecticidal lamp or general agent Of the same control effect, the technology in the middle or light borer occurred in the year can be large-scale popularization and application.
