性引诱国外以前就对昆虫的性引诱进行过研究。美国曾有人对分离家蚕和舞毒蛾的性引诱物作了试验,从而得到了浓度很低(1∶10,000)的昆虫性引诱物。在北美,为研究舞毒蛾的性引诱物,将雌虫腹部末端最后两节剪下,粉碎后浸入酒精溶液,再把经过滤的含有性引诱物的溶液滴在涂沫有松脂的磺化纸上制成粘性诱捕器。这种诱捕器设在树上,如果雄虫向诱捕器飞来,这说明在4公里内存在着害虫繁殖的基地,此方法可用来观察针叶及阔叶树食叶害虫的基地状况。
Sexual seduction before the insects on the lure conducted a study. In the United States, there have been attempts to isolate sex traps from silkworms and gypsy moths, resulting in very low (1: 10,000) insect attractants. In North America, in order to study the sex attractants of Gypsy moths, the last two sections of the ends of the abdomen of the female were cut off, immersed in an alcohol solution after crushing, and the filtered solution containing the entrainer was dropped on a rosin coated paper Made of sticky traps. This trap is located in a tree and if the males fly towards the trap, this indicates that there is a pest breeding base within 4 km. This method can be used to observe the status of the needle-leaf and leaf-leaf pest insects.
