The volatile composition of dichloromethane extracts of preputial glandular secretions (PGS) from intact and castrated male Brandt’s voles Lasiopodomys brandtii were analyzed by using gas chromatog.-mass spectrometry (GC-MS). Thirty-three volatile compounds were detected and were present in nearly all scent donors, and 27 had previously been reported as insect pheromone components. Castration did not eliminate any compounds; however, it significantly suppressed the relative quantity of ten early-eluting, low mol. weight components. These included seven saturated and unsaturated acetates, one hexanoate, and two saturated octanoates. In particular, E,E-farnesyl acetate (FA) was the most abundant compound in the PGS. FA and other components might be candidates for male-produced pheromones. Two-choice behavioral assays of females revealed that low concentrations of raw PGS (0.056%) and FA (5 ppm in water v/w) were attractive, whereas high concentrations (0.56% and 50 ppm, resp.) were repellent. This suggested that FA might act as a male pheromone in a dosage-dependent manner. Extremely high variability of the relative quantities of almost all detected compounds among individuals indicated the inter-individual dissimilarities of PGS and consequent possibilities to communicate individuality to other conspecific members.
