Studies of mitochondrial genomes have a wide range applications in phylogeny, population genetics, and evolutionary biology. In this study, we sequenced analyzed the genome Ooencyrtusplautus Huang & Noyes, 1994 (Hymenoptera, Encyrtidae). The nearly complete mitogenome O.plautus was 15,730 bp size, including 13 PCGs (protein-coding genes), 22 tRNAs, 2 rRNAs, control region. nucleotide composition significantly biased toward adenine thymine, with an A + T content 84.6%. We used reference sequence Chouioiacunea calculated Ka/Ks ratio for each set PCGs. highest value within found nad2 1.1, suggesting that they were subjected to positive selection. This phenomenon first discovered Encyrtidae. Compared other encyrtid mitogenomes, translocation trnW O.plautus, which its kind be reported Comparing ancestral arrangement pattern, wasps reflect extensive gene rearrangements. Although these insects high frequency rearrangement, species from same family genus tend similar sequences. As number Chalcidoidea increases, summarize some rules rearrangement Chalcidoidea, is four clusters frequent Ten mitogenomes included reconstruct phylogenetic trees Encyrtidae based on both (nucleotides protein coding genes) AA matrix (amino acids using maximum likelihood Bayesian inference methods. tree reconstructed by data showed Aenasiusarizonensis Metaphycuseriococci formed clade representing Tetracneminae. remaining six monophyletic Encyrtinae. Encyrtinae, Encyrtus forms as sister group Diaphorencyrtusaligarhensis. Encyrtussasakii Encyrtusrhodooccisiae most closely related clade. addition, rearrangements can provide valuable information molecular reconstruction. These results enhance our understanding relationships among
