Abstract

Abstract: Prostephanus truncatus (Horn, 1878) is a quarantine pest in the list of quarantine pests for imported plants of the People’s Republic of China, and no domestic distribution has been recorded in China yet. The taxonomic status, geographical distribution, host range, life history, damage characteristics and invasion risk of Prostephanus truncatus were systematically summarized. The morphological identification characteristics of adults, larvae, pupae and eggs were clarified, and a key to the related species of Prostephanus was compiled. A molecular identification system based on PCR amplification and sequence analysis of COⅠ gene was established. Morphological method was suitable for rapid on-site screening at ports, while molecular identification based on COⅠ gene could accurately distinguish incomplete specimens and related species. The combination of the two methods could form a complete and reliable identification system, which provided technical support for the quarantine, monitoring, early warning and control of Prostephanus truncatus.

Key words: Prostephanus truncatus, quarantine pest, morphological identification, related species, COⅠ gene
