Abstract. Tsetse ¯ies Glossina spp. (Diptera: Glossinidae) harbor three different
symbiotic microorganisms, one being an intracellular Rickettsia of the genus
Wolbachia. This bacterium infects a wide range of arthropods, where it causes a
variety of reproductive abnormalities, one of which is termed cytoplasmic
incompatibility (CI) that, when expressed, results in embryonic death due to
disruptions in fertilization events. We report here that in colonized ¯ies, Wolbachia
infections can be detected in 100% of sampled individuals, while infections vary
signi®cantly in ®eld populations. Based on Wolbachia Surface Protein (wsp) gene
