Major immunity genes in M. domestica and G. pallidipes: The immune genes described for the model insect, Drosophila melanogaster and the African malaria mosquito, Anopheles gambiae were obtained from the ImmunoDB [161]. The pathway for the putative immune-related proteins in G. pallidipes and M. domestica were verified by BLASTp searches at the Insect Innate Immunity Database (IIID) (≤10−6; bit score > 75) [164]. The pathways shown in this table have been reviewed by Kingsolver et al. [174]
