PERIPLANETA QUADRINOTATA, A COCKROACH WAS FIRSTLY INTERCEPTED AT TIANJIN PORT IN CHINA
Journal Title: Acta Parasitologica et Medica Entomologica Sinica - Year 2024, Vol 31, Issue 3
Abstract
[Objective] Periplaneta quadrinotata was captured by Tianjin Customs at Tianjin Port for the first time from a freight container on January 5, 2024. This study aimed to provide a reference including DNA sequence for cockroach species identification at frontier ports. [Methods] Primary morphological characteristics were described, and genomic DNA was extracted from a cockroach hind leg. DNA barcoding based on the mitochondrial COⅠ gene was provided for reference material. [Results] The diagnostic feature of the specimens is discernable four spots on the pronotum, accordingly, the intercepted cockroach was identified as P. quadrinotata. In addition, the CO I genes of the intercepted cockroach is identical to genus Periplaneta with 97% sequence homology, but different from those sequences of any known Periplaneta species deposited in GenBank. [Conclusions] P. quadrinotata is known to be reported in Thailand and other regions; however, related research have not been available in Chinese literature. Our re-description of the cockroach had been conducted with the intercepted specimens in a freight container based on its morphological characteristics and DNA barcoding features, which would aid custom technicians in making decisions for the quarantined species.
