据了解，S的几个种，包括L，石斑鼠和灰鼠，都有一段秋季的共生期。在春季的几个月里，在整个产卵过程中，这些种的雌虫体内都含有鞭毛虫。此外，除精巢外，该种雄虫的生殖系统在冬春两季仍处于正常工作状态。关于秋季交配过程中产生的精子是否与春季释放的卵子活动有关，或冬末和幼虫的精子是否受精的问题。针对这一问题，本文采用S等人的调查工具，对11只雄性L在恐惧期捕食灰斑潜蝇的繁殖情况进行了调查，并获得了有关雄性生殖系统状况与前人对这些物种雌帽的研究所表明的繁殖时期有关的信息。
It is kno~vn that several species of h t s , iilclncling l lyotis Iiicifiigus lncifugus and Myotis grisesceiis, have a period of fall coynilation. The females of sucli species arc found to contain spcrniatozoa in their i q r o d n c t i w tracts througl~ont tlie entire pei*iod of hibcrnntion aiid during tlic spring months. It is also kiiox-ii that the rcywoductive system, except the testes, of males of the species thus f w iiivestigatcd is niaintained in a functional condition tlii+oiighout the winter and spring. The question lias arisen as to wliether the spermatozoa dcposited during tlic fall copulation tire rcsponsiblc f o r actiratiori of tlie ovum which is liberated in the spring, or whether speixiatozoa from late winter and spi*iiig copalatioiis take p,ai*t iu fertilization. With this question in miiid the following investigation w a s miclc~i*talien to detci*mine the condition of tllc reproductive s p t e m of males of 11. l i ic i fups lucifngus aiid 11. grisescens at the vili~ious seasons of the Fear and to obtain information relating the condition of the male reproductive system to the periods of (~opulation a s indicated by previous studies on the female hats of these species.
