<jats:title>Abstract</jats:title><jats:p>Many arthropods harbour endosymbiotic bacteria of the genus <jats:italic>Wolbachia</jats:italic>. These endosymbionts are transmitted vertically from one generation to the next and are obligatory in several Dipterans that have been studied to date. These bacteria induce an array of reproductive isolation mechanisms that are implicated in pest management to evolutionary biology of respective hosts. The uzifly, <jats:italic>Exorista sorbillans</jats:italic>, a tachinid endoparasitoid of the silkworm, <jats:italic>Bombyx mori</jats:italic> L. (Lepidoptera: Bombycidae), causes enormous losses to the silk industry; now it is known that it harbours <jats:italic>Wolbachia</jats:italic> endobacteria. The elimination of <jats:italic>Wolbachia</jats:italic> by antibiotics interrupts embryogenesis and causes various reproductive conflicts such as (1) a reduction of fecundity of uninfected female, (2) cytoplasmic incompatibility in the uninfected females crossed with infected males, (3) genomic incompatibility in crosses between males and females from uninfected population, and (4) sex‐ratio distortion in uninfected females irrespective of the presence of <jats:italic>Wolbachia</jats:italic> in males. These results suggest that the relationship of <jats:italic>Wolbachia</jats:italic> with its uzifly host is one of mutual symbiosis as it controls the reproductive physiology of its host. Arch.
