本文介绍了雄性帝王蝶精囊对雄性和雌性生殖成功的影响的实验结果。圈养雄性的交配数量有很大的变化，这表明对雄性的强性选择的潜力。雄性寿命不受交配总数的影响，允许交配的雄性和不接触雌性的雄性之间也没有差异。本文报道了精囊对雌性行为或生殖力的两种影响：（1）接受大精囊的雌性比接受小精囊的雌性推迟再交配。(2)允许多次交配的雌性比单次交配的雌性产下更多的卵。这些影响的相对重要性进行了讨论有关君主交配模式。
SummaryI present the results of experiments designed to measure the effects of spermatophores produced by male monarch butterflies on male and female reproductive success. There was wide variation in the number of matings by captive males, suggesting the potential for strong sexual selection on males. Male lifespan was not affected by total number of matings, nor did it differ between males that were allowed to mate and those not exposed to females. Two effects of spermatophores on female behavior or fecundity are reported; (1) Females that received large spermatophores delayed remating longer than those receiving small ones. (2) Females allowed to mate several times laid more eggs than singly-mated females. The relative importance of these effects is discussed in relation to monarch mating patterns.
