Abstract: Parasitoid wasps are important natural enemy insects and are widely used in biological control. However, their applications in pest control face many problems, such as environmental adaptability and insecticide resistance. Cytochrome P450 is a supergene family of enzymes widely found in eukaryotes. It is involved in the metabolism of pesticides, plant secondary metabolites, etc. It is also involved in the synthesis and metabolism of hormones in insects. In this study, total 615 P450 genes were obtained by bioinformatics analysis from the Ceratosolen solmsi and 9 parasitoid wasp genome data. The analysis showed that the variance of P450 gene family in different parasitoid wasps mainly occurred in CYP3 and CYP4 clans, while CYP2 and Mito clans were relatively conserved. In the ectoparasitoids, the P450 supergene family of parasitoid wasps showed significant contraction. In addition, two P450 genes, CYP18 and CYP314, were highly 1:1:1 orthologous conserved in the parasitoid wasp, as well as the Braconidae specific gene CYP304 and the endoparasitoid specific gene CYP28. This study systematically analyzed the evolution of the parasitoid wasp P450 supergene family by comparative genomic analyses, and laid the foundation for the genetic improvement and large-scale breeding of parasitoid wasps in the future.
