Venoms secreted by the venom gland (VG) of parasitoid wasp help ensure successful parasitism by host immune suppression and developmental regulation.Cotesia vestalis, a larval endoparasitoid, andDiadromus collaris, a pupal endoparasitoid, parasitize the diamondback moth (DBM),Plutella xylostella. To explore and compare the venom components of two endoparasitoids, we sequenced transcriptomes of the VGs and wasp bodies without VGs (BWVGs) of the two endoparasitoids. Statistically enriched GO terms and KEGG pathways of the two VGs compared to respective whole-body background were similar and reflected active protein biosynthesis activities in the two VGs. 1,595 VG specific genes of theD.collarisVG and 1,461 VG specific genes of theC.vestalisVG were identified by comparative transcript profiling. A total of 444 and 513 genes encoding potential secretory proteins were identified and defined as putative venom genes inD.collarisVG andC.vestalisVG, respectively. The putative venom genes of the two wasps showed no significant similarity or convergence. More venom genes were predicted inD.collarisVG thanC.vestalisVG, especially hydrolase-coding genes. Differences in the types and quantities of putative venom genes shed light on different venom functions.
