Despite its substantial costs, sexual reproduction dominates in animals. One popular explanation for the paradox of sex is that asexual reproduction is more likely to accumulate deleterious mutations than sexual reproduction. To test this hypothesis, we compared the mitogenomes of two asexual wasp strains, <i>Trichogramma cacoeciae</i> and <i>T. pretiosum,</i> to their sexual relatives. These two asexual strains represent two different transition mechanisms in <i>Trichogramma</i> from sexual to asexual reproduction. Asexual <i>T. pretiosum</i> is induced by <i>Wolbachia</i>, while <i>T. cacoeciae</i> presumably originated from interspecific hybridization. We sequenced and assembled complete mitochondrial genomes of asexual <i>T. cacoeciae</i> and <i>T. pretiosum</i>. Compared to four sexual relatives, we found no evidence of higher mutation accumulation in asexual <i>Trichogramma</i> mitogenomes than in their sexual relatives. We also did not detect any relaxed selection in asexual <i>Trichogramma</i> mitogenomes. In contrast, the intensified selection was detected in Nad1 and Nad4 of the asexual <i>T. pretiosum</i> mitogenome, suggesting more purifying selection. In summary, no higher mitochondrial mutation accumulation was detected in these two asexual <i>Trichogramma</i> strains. This study provides a basis for further investigating mitochondrial evolution and asexual reproduction in <i>Trichogramma</i>.
