摘要以花蟋蟀（Gryllodes sigillatus）为研究对象，研究了雄性精鞘消耗对雌性适合度的影响。雌虫受精卵数量的增加并没有增加雌虫的产卵总数、产卵数和卵的孵化率，但增加了雌虫成虫早期的产卵数。卵期的持续时间随着精子层数的增加而缩短。讨论了精鞘不具有营养价值这一虚假假设的意义。
Abstract The effects of the consumption of the spermatophylax produced by males on female fitness were studied in the decorated cricket, Gryllodes sigillatus. An increase in the number of spermatophylaces presented to females did not increase the total number of eggs made by females, the number of eggs laid, or the hatchability of eggs laid by females, but increased the number of eggs laid in the early stage of adult life of females. The duration of the egg stage decreased with the number of spermatophylaces presented to females. The implication of the results on the sham hypothesis that the spermatophylax does not have nutritional value is discussed.
