昆虫性信息素是一种外激素,由昆虫产生,释放出体外,能够引诱或激起同种异性昆虫进行交尾活动的化学物质。随着研究的日益深入,目前,人们已经能够合成玉米螟、棉铃虫、棉红铃虫、高粱条螟、粘虫、地老虎等三十多种昆虫性信息素,并应用于测报、防治等生产活动中。有人预言,它将成为第三代农药——无公害的杀虫剂。昆虫性信息素具有高度的专一性和相当大的挥发性,一种昆虫性外激素,只能引诱同种异性昆虫,同时,性外激素在空气中的挥发传播很广。这就为性信息素在病虫防治工作中的应用奠定了基础。目前,性信息素主要被用于害虫测报防治,植物检疫以及害虫
Insect sex pheromone is a pheromone, produced by insects, released in vitro, able to lure or stimulate the same kind of insects to carry out cross-docking of chemical substances. With the deepening of the research, more than thirty kinds of insect pheromones such as corn borer, cotton bollworm, pink bollworm, sorghic stem borer, armyworm, tiger tiger and so on have been synthesized and applied to the measurement, prevention and treatment In production activities. Some people predict that it will become the third generation of pesticides - pollution-free pesticides. Insect sex pheromone has a high degree of specificity and considerable volatility, an insect sex pheromone, can only lure allorectic insects, at the same time, sex pheromones in the air of the volatile spread. This laid the foundation for the application of sex pheromone in pest control. At present, sex pheromones are mainly used for pest forecasting, phytosanitary and pest
