Abstract：
:In the oblique-banded leafroller, Choristoneura rosaceana, and the spruce budworm, C. fumiferana, male reproductive performance decreases with consecutive matings. While the onset time of mating did not vary, the time spent mating was longer in mated than in virgin males. Furthermore, a decline observed in the spermatophore mass with successive matings was associated with a concomitant decline in its apyrene and eupyrene spermatozoa content. In the hours following mating, spermatozoa migrate from the spermatophore, located in the bursa copulatrix, to the spermatheca. Regardless of the male's previous mating history, the number of apyrene sperm dropped rapidly in the days following mating whereas the number of eupyrene spermatozoa declined gradually. As the temporal pattern of sperm movement was similar in all treatments, females mated with previously-mated males would suffer from sperm shortage sooner than those mated with virgins. Large C. rosaceana females stored more apyrene spermatozoa in their spermatheca than small ones, irrespective of the time after mating or male mating history, while only large females mated with once-mated males received more apyrene sperm and accessory gland secretions than small ones mated with virgin or twice-mated males. The results obtained in this study are discussed in relation with their potential impact on the reproductive success of both sexes.
