Abstract: By using monitor and special behaviors recording method, a laboratory study was made on the influence of male hierarchy on female choice of L. brandtii. The results showed that there was no significant difference in odor preference and individual preference, no matter the female vole was on estrous or not. The estrous female took on more self-grooming behavior than the non-estrous female in both the odor preference and the individual preference experiments. On the selection priority, estrous female would first select the odor or individual of dominant male and mate with it, while non-estrous female would first select the odor or individual of subordinate male. The female choice of L. bramdtii was not only influenced by male hierarchy, but also influenced by the physiological status of female vole.
