摘要：

Males of many insect species provide large ejaculates that females may use for somatic maintenance and egg production. Male cowpea weevils, Callosobruchus maculatus (F.), contribute large ejaculates in their first mating, averaging >5% of male body mass. Here, we quantify the influence of repeated matings on male ejaculate size in C. maculatus and find that multiply mated males produce much smaller ejaculates than once-mated males. Some of this effect, however, is compensated for if males increase the length of time between matings. Male age also has a large effect on ejaculate size; two-day-old males produce larger ejaculates than either young or old males.
