Carpomya pardalina is known for its potential invasiveness, which poses a significant and alarming threat to Cucurbitaceae crops. It is considered a highly perilous pest species that requires immediate attention for quarantine and prevention. Due to the challenges in distinguishing pests of the Tephritidae family based on morphological characteristics, it is imperative to elucidate the mitochondrial genomic information of C. pardalina. In this study, the mitochondrial genome sequence of C. pardalina was determined and analyzed using next-generation sequencing. The results revealed that the mitogenome sequence had a total length of 16,257 bp, representing a typical circular molecule. It consisted of 13 PCGs, two rRNA genes, 22 tRNA genes and a non-coding region. The structure and organization of the mitochondrial genome of C. pardalina were found to be typical and similar to the published homologous sequences of other fruit flies in the Tephritidae family. Phylogenetic analysis confirmed that C. pardalina belongs to the Carpomya genus, which is consistent with traditional morphological taxonomy. Additionally, Carpomya and Rhagoletis were identified as sister groups. This study presents the first report of the complete mitochondrial genome of C. pardalina, which can serve as a valuable resource for future investigations in species diagnosis, evolutionary biology, prevention and control measures.
