摘要/Abstract

摘要： 大谷蠹（Prostephanus truncatus Horn,1878）是中国进境植物检疫性有害生物,目前国内尚无分布记录。系统总结了大谷蠹的分类地位、地理分布、寄主范围、生活史、危害特征及入侵风险,明确了成虫、幼虫、蛹、卵的形态鉴别特征,编制了尖帽胸长蠹属近似种检索表,建立了基于COⅠ基因的PCR扩增与序列分析分子鉴定体系。形态学方法适用于口岸现场快速筛查,COⅠ基因分子鉴定可对残缺标本及近缘种实现精准区分,二者结合可形成完整可靠的鉴定技术体系,为大谷蠹的口岸检疫、监测预警与防控处置提供技术支撑。

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
