Mate choice is a common phenomenon in animals and several factors have been proposed as being involved in the acceptance or rejection of a partner. I investigated the effect of population density on the mate-sampling behaviour of female Xederra charactus (bushcrickets). In my study, female bushcrickets adjusted the tactic of sequential mate sampling in response to mate density, visiting a series of up to five different males per night. Under low-density conditions, females visited fewer males in a night and were less likely to reject a copulation attempt than females under high-density conditions. Rejection of a male occurred during 29% of copulations in areas of high population density, but during only 8% in areas of low population density. Moreover, at low densities, females were less likely to reject mates later in the night, which can be interpreted as a reaction to the time constraints of a finite nightly mating period. Females in high-density populations also more often chose males with a higher mass of the spermatophore-producing accessory glands. Due to such choice, females might receive a larger nuptial gift at mating. These results are consistent with tactical models of search behaviour in which females adjust their behaviour to the number of potential mates and the length of the mating period.

ABSTRACTMate competition and selection of mates is strongly influenced by the organism’s mating system. Monogamous matings provide more benefits as compared to polygamous matings. However, it has been proven that in polygamous systems, females gain benefits from the males, therefore indulging in multiple mating, leading males to access maximum females. In zigzag ladybird, Menochilus sexmaculatus, mate choice has been studied on several pre-and postcopulatory factors. However, mate choice as a function of mating system is still remains untouched. In the present study, we hypothesised that the mating system modulates mate selection of beetles. Adults were held in different mating systems and then males and females were tested in mate choice trials. Polygynous males were more preferred over monogynous males. However, males preferred monandrous females over polyandrous females. In a second experiment, we also included relatedness as additional factor. In female mate choice trials, females preferred unrelated monogynous males which were earlier rejected over related polygynous and in male mate choice trials, males preferred unrelated polyandrous females over related monandrous females. The results were not confined only to mate choice but significant effect was also observed on time to commence mating, copulation duration, fecundity and percent egg viability.
