摘　　要：通过观察非动情期的棕色田鼠对麻醉的同种个体身体气味源的探究行为 ,包括雄鼠对麻醉雄鼠和雌鼠的嗅闻、雌鼠对麻醉雄鼠和雌鼠的嗅闻 ,分析了棕色田鼠在社会探究中对不同气味源的反应格局。结果表明 ,棕色田鼠对同种个体肛殖区和面部的嗅闻频次及嗅闻持续时间最多 (P <0 0 5 ) ;对背部、腹部、肋部嗅闻的频次和持续时间较少。在对同一部位的嗅闻中 ,在嗅闻频次上 ,雄鼠对雄鼠的嗅闻、雌鼠对雌鼠的嗅闻以及雌鼠对雄鼠的嗅闻都显著多于雄鼠对雌鼠的嗅闻 (P <0 0 5 ) ;在嗅闻时间上 ,性别组合对同一部位的探究行为没有显著影响 ,但气味源与性别组合有交互作用 (P <0 0 5 ) ,影响探究行为。这些结果说明棕色田鼠的肛殖区和面部是重要的气味源 ,而且在对同一气味源的探究中存在性别差异。但在非动情期 。It was observed that investigating behavior of anoestrus Mandarin voles (Microtus mandarinus) for different odor sources of anesthetized conspecific individuals, including males sniffling anesthetized males and females as well females sniffling anesthetized males and females. Results showed that Mandarin voles displayed a greater number of investigations for anogenital region (A R) and face than for any other body part ( P <0 05); Sniffling frequency and duration was lower in the regions of back, venter, and flank. Sniffling frequency for the same region of males to males, females to females, females to males was higher than that of males to females ( P <0 05); Sniffling duration for the same region of gender arranging in pairs had no significant influence, but odor sources and gender arranging in pairs had interaction which influenced investigating behavior ( P <0 05). These results indicate that A R and face are important regions for the voles producing individual odor information. Although gender difference for the voles investigating the same odor source was found, yet not all investigations of heterosexual individuals are more than those of homosexual individuals in the anoestrus period.
