species, it was hypothesized that heterospecific odours were more aversive (or less attractive) than conspecific odours. It was not expected beforehand that conspecific odours would be avoided because, in hamsters, gerbils, rats and mice, conspecific alien odours possess at- tractive rather than repellent

solutions (food odor, conspecific odor plus food odor, heterospecific odor plus food odor). We found that the two species differ on one hand for their background behavior and on the other for the intensity and quality of their responses to the three types of cues. Firstly, P. clarkii appeared more active

alarm substance was attenuated. Two interesting patterns arose that differed substantially from the prevailing paradigm: (1) conspecific odors remained repellent after 96 h of aerobic decay; and (2) the cue was emitted from multiple areas of the body, not just the skin, and the repellency of the odor

between and preferences for conspecificsodors may not be achieved by the same process as detecting and discriminating the odors of potential predators. Thirdly, Johnston & Peng ( 2000 ) and Petrulis et al. ( 1999 ) showed that the VNO is not essential for the discrimination of conspecific odor or for

The social environment of animals, particularly in the early stages of life, can have great impact on species-specific and sex-specific behaviours. These changes can be irreversible and continue during the entire life. In the present study we asked the question whether the social environment of male Endler’s guppies, Poecilia wingei, housed in an all-male community could affect their preference response to female or male odour cues in a flow through Y-maze. After 30 days in an all-male group males were tested for their preference-avoidance responses to conspecific odours. The males were attracted to male-scented water but not to water scented by females. In simultaneous choice between male and female odours they demonstrated no significant preference. The males were attracted to male-scented water after they were kept for 48 h or 12 days with females. After the Y-maze tests the males’ were placed with two females and their courting behaviour were recorded. The males showed low frequencies of reproductive behaviours. In the all-male group the males had been courting each other. The results show that the social environment influence sexual odour preference and courting behaviour in guppy males.

, both sexes detect conspecific odours, as indicated by elevated tongue-flicking rates directed to odour-impregnated cotton applicators. Both sexes detect conspecific cloacal odours; males additionally detect skin odours. Males, but not females, discriminate between male and female cloacal odours and

that suggests the importance of chelae in sex recognition is the chelae sampling behaviour in the presence of conspecific odour. Chelae waving behaviour has been described by Thorp & Ammerman (1978) and Itagaki & Thorp (1981) in the crayfish, Procambarus clarkii (Girard, 1852). These authors
