香蕉蝙蝠（Neoromicia nanus）的特点是季节性单情繁殖。本研究调查了南非姆普马兰加省奈努斯的繁殖时间和策略。对雄性和雌性蝙蝠进行组织学检查，以确定它们全年的生殖状况。香蕉蝙蝠的精子发生始于9月下旬，精子于4月下旬至7月下旬释放到附睾尾。整个8月，精子仍然存在于附睾尾。五月开始交配，八月初排卵受精。8月初首次植入，10月下旬至11月底分娩。直到1月中旬才发现哺乳期雌性。与马拉维的同一物种相比，在姆普马兰加，雌性精子似乎没有储存，雄性精子只储存很短一段时间。普马兰加省的生育时间比马拉维大约早一个月。
The banana bat, Neoromicia nanus, is characterized by seasonal monoestrous breeding. This study examined the reproductive timing and strategies used by N. nanus in the Province of Mpumalanga, South Africa. Male and female bats were histologically examined to determine their reproductive condition throughout the year. Spermatogenesis in the banana bat began in late September and spermatozoa were released into the caudae epididymides from late April to late July. Spermatozoa remained present in the caudae epididymides throughout August. Mating was initiated in May and ovulation and fertilization occurred at the beginning of August. Implantations first occurred during early August and parturition followed from late October to the end of November. Lactating females were found until mid January. In contrast to the same species in Malawi, it appears that in Mpumalanga no sperm storage takes place in females and occurs for only a short period in males. Reproductive timing was approximately one month earlier in Mpumalanga than in Malawi.
