Mating frequency, fecundity and fertilization success in the hide beetle, Dermestes Maculatus

Abstract

While the immediate benefits accrued to females through multiple mating are well documented, the effect of sperm depletion for multiply mating males is rarely considered. We show that, in small mixed-sex laboratory aggregations, both male and female hide beetles, Dermestes maculatus (De Geer) mated multiply. There was considerable variation in the mating frequency of both sexes; however the skew in mating success was comparable for males and females. Several individuals that mated multiply also re-mated with a previous partner, but in a competitive environment no male copulated more than seven times. Mating success was unrelated to an individual's size, but males that had the most inter-sexu..
