Abstract
The cytoplasmically inherited bacterial symbiont, Wolbachia is well known for inducing a variety of reproductive abnormalities in the diverse arthropod hosts it infects. Wolbachia has been implicated in causing cytoplasmic incompatibility, parthenogenesis, and the feminization of genetic males in different hosts. In the present investigation, electron microscopy and PCR technology was applied on uzi flies of Exorista species (Diptera : Tachinidae), serious pests of silkworm Bombyx mori L. TEM examination of uzi flies of Exorista species showed Wolbachia in the reproductive tissues. Details of the ultrastructure of Wolbachia are described. The application of PCR technique revealed that the Wolbachia is present in uzi fly populations of Exorista species collected from different localities. Thereby it creates a lot of scope for future research on the management of uzi flies by means of Wolbachia.
