【摘要】 <正> 哺乳动物的化学通讯,是近年来逐步被人们认识的一个重要领域,而外激素是行使动物间通讯联系的化学信使。所谓外激素,一般是指动物由外分泌腺排放于休外的挥发性的化学物质或物质的混合物,有的直接释放于体外,有的则通过尿、粪便、唾液等排于体外,它能引起同种的受纳个体产生一系列的行为、生理反应。鉴于对哺乳动物外激素研究尚属—新领域,许多问题尚待进一步探讨,所以目前把凡能引起上述反应的外分泌产物统称为外激素。更多还原

【Abstract】 The knowledge of chemical communication in mammals has not yet proceeded so faf as to be applied to pest control.In spite of the limited knowledge on phero-mones,we have speculated on the possibility of using these substances in biological control.The urine of estrous Microtus brandti might be used to increase the attractiveness of traps (Tab.2),and of baits (Pig.1).Results of our experiments suffice to show the potential possibilites of controlling small rodents by means of their own communication substances.更多还原
