The egg production of individual virgin and mated female Aedes aegypti was investigated under laboratory conditions. No differences in the engorgement rates were observed. However, the continuously mated females deposited a statistically and significantly greater number of eggs per mosquito than did the virgin and partially mated females. These differences were attributable to the large proportion of females in the latter groups which laid few or no eggs. In these experiments, therefore, almost all ovipositing females, regardless of their mating conditioning, laid approximately the same number of eggs. An additional finding of this study was the delayed oviposition times of virgin mosquitoes.
