Expression heatmap of the expanded gene families in different tissues and stages. The colors represent the level of gene expression from low (purple) to high (yellow) as shown by log10 (FPKM + 0.000001). E (eggs), L2 (second-instar larvae), L4 (fourth-instar larvae), P (pupae), F (female adults), M (male adults); An (antenna), H (head), T (thorax), Ab (abdomen), L (leg), and Sg (female sexual gland). a Expression heatmap of the CSP gene family. The transcripts that were grouped together and specifically expressed in the antennae are EVM0003477, EVM0000271, EVM0002854, EVM0002317, EVM0009785, EVM0004106, EVM0004147, EVM0005331 and EVM0008758. The transcripts that were highly expressed in pupae are EVM0014103, EVM0014851, EVM0003329 and EVM0014642. The transcripts that were specifically expressed in the sex gland are EVM0010490 and EVM0014431. b Expression heatmap of the CCE gene family. c Expression heatmap of the GST gene family. d Expression heatmap of the UGT gene family. The heatmaps were constructed with HemI (windows_1_0_win32_x64) using the DEGs of each expanding family. The expression levels are presented by the color bar from low expression as green with negative numbers and high expression level as yellow with positive numbers
