Morphology, behavior, development, survival and reproduction of the parasitoid were studied in this paper.

本文对该蜂的形态、行为、发育、存活、繁殖等生物学特性进行了观察研究。

Host plants affected the survival, development time and reproduction of P.xylostella and indirectly affected the survival, development time, fecundity and sex ratio of the parasitoid.

6小菜蛾及菜蛾绒茧蜂的生存、发育、繁殖等均不同程度地受寄主植物的影响，小菜蛾成虫期的产卵嗜好性并不反映植物对其幼虫期的相对适合度。

However, reproduction is often by parthenogenesis since polyploid animals are often sterile.

然而，它们常常是通过孤雌生殖繁殖的，因为多倍体动物往往不育。

Although bees, ants and some fish and reptiles reproduce without having sex in a process known as parthenogenesis, it was thought to be impossible in mammals.

尽管蜜蜂、蚂蚁和一些爬行动物通过孤雌生殖进行繁殖，但哺乳动物被认为是不可能进行这种生殖的。

In nature, clones are derived from a single parental organism or cell by mitotic cell division, asexual reproduction, or parthenogenesis.
