Fig. 8.

Model for D. melanogaster germline colonization by Wolbachia. Female fruit flies and corresponding ovarioles are shown. Wolbachia infection is indicated by purple dots. Wolbachia titers carried bodywide and in early oogenesis did not show any consistent response to host diet. However, Wolbachia titers from late oogenesis are markedly lower in yeast-enriched conditions than on un-enriched food. This is consistent with possible developmental regulation of Wolbachia invasion and/or replication in maternal germline cells
