Evolution of chemosensory receptors genes in A. suturalis. a Gene number comparison of chemosensory receptor genes between A. suturalis and other species in Hemiptera. b–e Maximum likelihood phylogenetic and chromosomes distribution of OBP, OR, GR, and IR genes in A. suturalis, A. lucorum, and D. melanogaster (Dm). The species-specific expanded clades are emphasized with shadow. Different clades are labeled in different colors. f Expression profiles of A. suturalis OBP, OR, GR, and IR genes from individuals at different tissues and developmental stages. The color intensity changes with the relative expression from low (green) to high (red). The color bar above the heatmap indicates different gene families or subfamilies. F, female; M, male; FB, fat body; H, head; M, midgut; O, ovary; SG, salivary gland; 1, 1 day; 11, 11 day; AIR, antennal ionotropic receptors; AICR, antennal ionotropic co-receptors; DIR, divergent ionotropic receptors
