摘要
为探究黄毛鼠的婚配制度,通过雌雄黄毛鼠对熟悉和陌生异性鼠的选择实验和遭遇实验,分析了熟悉性对两性间行为的影响。结果发现,选择实验中雌鼠对陌生雄鼠的关注频次比对熟悉雄鼠的更多;遭遇实验中尽管雌鼠探究和自身修饰行为、雄鼠的活动和攻击行为在遭遇熟悉或陌生异性鼠时有差异,但雌雄鼠的友好行为均无显著差异,暗示黄毛鼠是多配制,但需进一步确定其是否属于混交制、一雄多雌制或一雌多雄制,可为制定野外不育控制黄毛鼠策略提供行为学依据。
To reveal the mating system of lesser rice-field rat Rattus losea,female and male R.losea were involved in pair-choice preference tests and dyadic encounters toward familiar and/or unfamiliar conspecies from the other sex.Pair-choice preference tests have displayed that the frequencies of caring behavior of females towards unfamiliar males were more than that towards familiar males.In the case of males,this preference was statistically not significant.The other factors of both females and males were not significant.Dyadic encounters have showed that females exhibited more frequencies of investigation behavior and more time and frequencies of self-grooming when they encountered familiar males than that when they encountered unfamiliar ones.Males performed more locomotion behavior in frequencies and aggression in time and frequencies when they encountered unfamiliar females than that when they encountered familiar ones.However,amicable behavior of both females and males were not significant.The factors of stimulus rats were not significant.All rats involved in encounters performed no aggression to familiar opposite sex and no sexual behavior to unfamiliar ones.The results have suggested that the mating system of R.losea is not monogamy,but what kind of polygamy needs to be confirmed further,which will provide suggestion to fertility control of this species.
