Summary of Sitophilus immune responses to its primary endosymbiont SZPE based on [6]. The left box indicates the constitutive response of bacteriocytes to the dense population of endosymbionts within it; the right box indicates the reaction of the rest of the body when bacteria 'escape' from the bacteriome into the insect's hemocele (body cavity). Not all of the genes studied in [6] are listed here.
