Expression of putative chemosensory genes in larvae and different adult tissues of S. inferens.

The relative expression levels of genes in the same tissue were calculated by the ratio of the RT-PCR bands intensity between target gene and internal reference gene SinfGAPDH[73](Figure S1). *, **and *** indicate the intensity ratio of 0.20-0.59, 0.60-0.99, 1.00-1.39, respectively; the blank indicates no signal. The band intensity was calculated by Bio-Rad-Quantity one 4.6.2 software). La, larvae (third instar); Adult tissues include PG, pheromone glands; A, antennae; H, heads (without antennae); T, thoraxes; Ab, abdomens (female without PG); L, legs and W, wings. ♀: female, ♂: male. Superscript “a” followed the gene name represents that the expression level of the gene was obtained by two biological replications.
