An experiment was initiated to determine the optimum ages for mating of male and female G. pallidipes. Males of 7, 10 and 13 days after eclosion were mated with females of 3, 5, 7 and 9 days. The 12 possible matings were accomplished with equal numbers of males and females. The experiment was then repeated using twice the number of males. The main conclusions drawn were as follows. 1. The mortality of 3-day-old females during the mating period was much greater than amongst females mated at 5, 7 or 9 days. 2. There was no advantage in using twice the number of males to females as opposed to equal numbers of each. Pupal production was not significantly different, and the abortion rate was similar, although abortions were observed more often in the 1:1 mating series. 3. There was no difference in the production of females mated with 7-, 10- or 13-dayold males. 4. The age of females at mating was found to be the most important factor. Females mated when 3 or 5 days old gave lower production than those mated when 7 or 9 days old.
