Interpretive Summary: Asian citrus psyllid (Diaphorina citri) is an important pest that transmits the pathogen of Huanglongbing (HLB), a highly destructive disease affecting citrus production worldwide. For effective management strategies, knowledge of the insect population diversity is needed. For this purpose, the mitochondrial genome of an Asian citrus psyllid vector from Guangdong, China, where HLB was first described, was sequenced. This is the first complete mitogenome sequence of Asian citrus psyllid that will serve as a reference to identify genetic markers for future population studies.

Technical Abstract: The first complete mitochondrial genome (mitogenome) sequence of Asian citrus psyllid, Diaphorina citri (Hemiptera: Psyllidae), from Guangzhou, China is presented. The circular mitogenome is 14,996 bp in length with an A+T content of 74.5%, and contains 13 protein-coding genes (PCGs), 22 tRNA genes (tRNAs), 2 rRNA genes, and an AT-rich control region. Synteny was identical to the ancestral insect mitogenomes. All PCGs start with “ATN” codons. Eleven PCGs use the complete termination codons (“TAA” or “TAG”), while the remaining two (cox2 and nad5) use a single “T” as the stop codon. All tRNAs have the typical cloverleaf structure, except for tRNA(trp) which lacks the variable arm and tRNA(ser) (AGN) which lacks the dihydrouridine arm. A phylogenetic tree, including twelve members of Sternorrhyncha, was constructed based on the 13 PCGs sequences. The resulting phylogenetic tree matched the established taxonomic scheme based on morphology.
