摘要
本文首次报道了白马蝠蛾的生殖系统和生殖习性。白马蝠蛾雌性生殖系统与鳞翅目其他昆虫不同:无粘液腺器官;成虫产卵行为特殊,卵散产,产后有用尾和足扫土盖卵的习性;成虫交配授精以精包方式进行。交配除提供雌蛾精于外,还能刺激产卵。雌蛾生殖力强,生殖期短,产卵最多768粒,最少364粒,一生平均621粒,生殖期平均4.2天;成虫历期平均6.2天;卵平均历期48.6天(温度12.6℃)。最适宜成虫交配与产卵的温度为12.5—19.0℃,相对湿度76％—90％。
In this paper, the author reports the reproductive system and reproductive behavior of He pialns baimaensis Liang. The results may be summarized as follows: The female reproductive system of the H. baimaensis is distinctly different from that of the other Lepidoptera insects. It has not the colletcrial gland. The male inseminnates the female by the form of the spermatophore which contains sperms as the other Lepidoptera does. These arc formed by accessory glands secretion, namely the spermatophore gland, accessory glands and the seminal vesicle. The copulation not only provides the sperms but also promotes oviposition. The parthenogenetic female could lay eggs, but none of the parthenogenetic eggs could behatched, and the number of eggs was obviously decreased. The female reproductive capacity is quite strong. The total number of eggs laid by each female H. baimaensis varies between 364-786. The period of reproduction was short, only 3-7 days. The imago needs 6.2 days for life cycle. The duration of eggs is about 48.5 days (12.6℃). The most suitable temperature and relative humidity for mating and oviposition are 12.5 -19.0 ℃ and 75%-90% respectively.
