Browne, P. Smith, A. van Gerwen, C. Gillott] Virgin females of Lucilia cuprinararely lay eggs, whereas mated females do so readily. This effect of mating is due entirely to increased readiness to lay, and not to any effect on ovarian development. An investigation was made of how readiness to lay was affected by matings which differed in terms of the male's chemical and mechanical contribution. Individual males were mated, during 1 day, to a succession of females whose readiness to lay was determined 1 or 8 days after mating. On both days, the proportion of females laying was inversely related to the number of females with which the male had previously mated. A high proportion of females that had mated with previously unmated or oncemated males laid at both 1 and 8 days after mating. However, this proportion tended to decline between day 1 and day 8 in females that had mated with males with two or more previous matings, and this effect was most evident in females mated with males that had previously mated with four or more females. When matings were manually terminated as soon as coupling had occurred, the proportion laying remained as low as in virgins. This proportion progressively increased as mating duration increased from 2 to 6 min. The proportion that laid after mating terminated at 6 or 8 min was as high as that for females from full-term matings (mean duration, 12.5 min). The results are generally similar to those obtained in parallel experiments on the effect of mating on sexual receptivity in this species and, therefore, indicate that the physiological bases for the two effects of mating might be the same.
