Figure 2. Mealybug endosymbiosis.

Figure 2

The citrus mealybug P. citri has two endosymbionts, T. princeps and M. endobia. M. endobia is an endosymbiont of T. princeps, and T. princeps is in turn an endosymbiont of the mealybug. These T. princeps in turn reside in the mealybug bacteriocyte, a specialized cell where the insect houses endosymbionts.
