Mating behavior of muscoid diptera was modeled to show how the different components can influence mating success. The parameters studied were the effect of rejection on the male (male vigor) and the required amount of courtship summation and rejection rate of the female (female vigor). In a simulated cross of two strains each sex had some influence on the numbers of each type of mating and on the timing of the matings. However, the males had the most control over the numbers of matings of each type, while the females exerted the most control over timing of mating. Results of computer simulations and of laboratory experiments on Musca and Drosophila were compared; the predominant effect in all the analyses was the superiority of the vigorous males.
