Inter- and intraspecific sexual discrimination in the flour beetles Tribolium castaneum and Tribolium confusum



Inter- and intraspecific sexual discrimination in the flour beetles Tribolium castaneum and Tribolium confusum



Heredity: an international journal of genetics 85(2): 142-146



In Tribolium castaneum (CS) and T. confusum (CF), intra- and interspecific rates of homosexual mounting have been measured. The intraspecific results are compatible with the hypothesis of both species being sexually indiscriminate. However, the CF intraspecific rates were very high (35%-53% of mountings were homosexual), suggesting a lower sexual attractiveness, or a stronger rejection to being mounted, of CF females relative to conspecific males. CS males discriminate between species but, in interspecific contacts, preferentially mounted CF males rather than CF females. CF males do not discriminate between species, but the loss of sexual attractiveness of CF females, or their rejection to being mounted, may act as a precopulatory isolation mechanism.
