摘要： 1986~1991年对毛黄金龟生物学习性及利用性外激素诱杀雄虫方法进行了研究，结果表明，毛黄成虫出土整齐而集中；雌虫仅能短距离爬行、交尾后即就近入土产卵，长年形成封闭式危害区域；成虫性间诱集力极强；雄虫只有一次有效交尾能力，雌虫可以多次交尾。这些特性有利于性激素使用。试验表明，性外激素在雌虫腹部产生，用乙醚提取活性最高。其粗提物可在0~10℃温度下贮存二年仍具有较强活性。在田间自然状态下释放粗提物诱杀毛黄雄虫，处理区比对照区毛黄幼虫量减退96。9%。

Abstract: The research result showed that all of the adult Holotrichia trichophora (Fair-maire) could go out simultaneously from soil in a short time.Female adult could crawl only a short distance and oviposit nearby in soil after coitus.As a result, a closed destroyed region would be formed.It was found that sex lure between male and female adults was very strong.Male adult could only coitus one timetbut the female many times.These behaviours of the insect can be used in the pest control.It was also showed in the test that the sex hormone could be collected with ether from abdomen of the female adult and the rough extractive material could be stored in 0-10℃ for two years,and then the activity would be still strong.It was also found that use of the rough extractive material in natural condition could reduce population of the pest by 96.9% as compared with the control plot.
