摘 要: 沃尔巴克氏体(Wolbachia)是广泛分布于节肢动物生殖组织内的一类共生细菌。它们通过共生诱导宿主赤眼蜂的产雌孤雌生殖,在生物防治上具有重要意义。文章概述了Wolbachia在赤眼蜂中的分布状况,对赤眼蜂的性别调控机制,在赤眼蜂种群中的传播及限制因素,以及对赤眼蜂适合度的影响。 Wolbachia is a common and widespread group of bacteria found in reproductive tissues of arthropods. These bacteria are transmitted through the cytoplasm of host eggs. And the thelytokous parthenogenesis of Trichogramma induced by Wolbachia is important in biological control. This paper summarizes the new research progress on the distribution of Wolbachia, sex determination on Trichogramma, the transfer among Trichogramma population, and the effect on the fitness on Trichogramma.
