Figure 1 - in situ hybridization with wsp specific probe and staining with NBT/BCIP solution on uninfected A and Wolbachia infected Drosophila simulans B. An accumulation of dark color is observed only in ovarioles of Wolbachia infected Drospohila simulans. C Results of in situ hybridization of ovarial tissue excised from one Pityogenes chalcographus individual with accumulation of dark color (arrows). Three specimens were analysed. All ictures taken with 40-fold magnification.
