The influence of chemical cues from conspecifics on female bank voles Clethrionomys glareolus (Schreber, 1780) activity was investigated in a 10 min behavioural test. The role of the main olfactory and vomeronasal systems in mediating chemicals which alter female activity was also studied. Total activity scored higher in females exposed to the scent of dominant male or adult male urine. The odour of subordinate male, castrated male and female urine had no effect on female activity. Bulbectomy but not vomeronasalectomy decreased female activity in the presence of an adult male. The results are discussed in terms of possible biological functions of such behaviour.

Housing females in groups prolongs the dioestrous phases in cycling laboratory mice Mus rnusculus Linnaeus, 1758. Olfactory signals play an important role in interaction between females, and the vomeronasal system is involved in mediation of hormonal responses to pheromones. Present results show that removal of the vomeronasal system (VNX), or bulbectomy (OBX), leads to in decreased numbers of oestrous mice in comparison to non-operated (NON) or sham-operated (SHAM-OBX) singly reared females. Oestrous cyclicity was also affected by social factors. Cohabitation of NON, VNX, OBX or SHAM-OBX females with adult females results in decreased oestrous frequency in comparison to females reared alone. Moreover, VNX females exposed to male bedding inhibited oestrus in comparison to nonexposed VNX animals. The results provide evidence that different external stimuli evoke hormonal responses which are manifested in inhibition of oestrous cycle in female mice.
