Abstract: Parasitoid wasps are important natural enemies of pests. Elucidating the evolution and functions of wasp miRNAs can be helpful for better understanding the biological characteristics of wasps. Here, we identified the miRNAs from 19 Hymenopteran insects including 6 parasitoid wasps. The miRNA gene families of these species were also identified. The evolutionary analysis of conserved miRNA families in Hymenoptera insects revealed 12 Hymenoptera-specific miRNA families, implying a large-scale gain of miRNAs during the early evolution of Hymenoptera. miRNA families showed multiple independent loss in parasitoid linage Orussidae, Chalcidoidea and Braconidae. The work provides a basis for further exploration of miRNA-gene target relationships in parasitoid wasps.

Key words: Hymenoptera, parasitoid wasp, miRNA gene, miRNA family
