【摘要】 <正> 黄兔尾鼠(Lagurus lutens)及草原兔尾鼠(Lagurus lagurus)是新疆某些地区主要害鼠之一,它们的繁殖能力很强,数量高峰时,对草场危害极大。此外,它们还能传染某些地方性流行病,所以对这两种害鼠的防治是十分必要的。 近年来,我们在研究动物化学通讯的过程中,了解到外激素(信息素)在动物间传递信更多还原

【Abstract】 Lagurus luteus and Lagurus lagwus are two economically important rodent species belonging two to one taxonomic groups.Two voles have most developed exocrine glands i. e. preputial gland, anal gland and hardian gland. The function of these glands as scent releasing organ was examined only in specific aspects .We found that the musky secretion of the preputial gland was attractive to animals of the opposite sex. The odours released by the preputial gland which produced pronounced arousal and attraction may have carried one or more of these other chemical messages to the animals being tested.The odours released by the anal gland exert territory marking effect. The substance serves recognition role between individuals or social groups. Secretion from anal gland of one species may be trigger specific reactions in individuals of other species.Secretion from anal gland analogue to a fear/alarm substance might prove an efficient repellent (Fig.5). Examination of experiment reveals that the odour of strange group of anal glands decreased the mean weight of testicle. It shows that the anal odour caused a significant decrase in weight of testicle over the control value (t0.05<t).Communecation within and between species has in many cases turned out to be more important in regulating populations than the "classical" ecological factors. The knowledge of chemical communication in mammals has not yet been proceeded so far that it can be applied for biological control. We will speculat about the applicabiliy of some^function of anal gland to the qustion of biological control.更多还原
