Analyses of differentially expressed genes (DEGs) of a-e Coccinella septempunctata (CS), f-j Harmonia axyridis (HA), k-o Propylea japonica (PJ) and p-t Cryptolaemus montrouzieri (CM) in two prey treatments. DEGs were identified using volcano plots. Horizontal coordinate: log2(fold change), vertical coordinate: -log10(Q-value). The studied genes were coloured, and those DEGs were marked as solid circle. Information of Pfam accession of genes can be found in Additional file 1: Table S7. The raw transcriptome data of CM were from our previous study [11]
