Abstract

Wolbachia-like organisms (WLOs) are described in strains of Drosophila simulans exhibiting the phenomenon of cytoplasmic incompatibility. When thin sections of testes of males of type R strains (which produce few progeny when mated with females of type W strains) were examined by electron microscopy, WLOs were detected in 12 of 19 flies from four different type R strains. In contrast, no WLOs were found in testes of 16 flies from two strains of type W female flies. WLOs were also found in the ovaries of type R, but not type W, flies. In type R strains treated with tetracycline, no WLOs were found in testes; this is in accord with the known ability of tetracycline treatment to restore compati..
