危险性潜在入侵害虫角胸长蠹的检疫鉴定

Quarantine and identification of Bostrychoplites cornutus(Olivier,1790),a pest of potential invasion risk

角胸长蠹(Bostrychoplites cornutus(Olivier,1790))分布于非洲、亚洲、欧洲、北美洲等地区,主要为害白梧桐(Triplochiton scleroxylon)、墨西哥丁香(Gliricidia sepium)、罂粟尼索桐(Nesogordonia papaverifera)等经济植物,我国口岸曾多次截获该虫,该虫在我国存在潜在的入侵威胁。本研究对角胸长蠹的分类地位、形态特征、分布、寄主等方面进行介绍,同时列出角胸长蠹与其近似种的形态区别,简化其检疫、鉴定难度,为口岸鉴定提供一定参考价值。

Bostrychoplites cornutus(Olivier,1790)is distributed in Africa,Asia,Europe,North America and other regions,and it mainly infests economic plants such as Triplochiton scleroxylon,Gliricidia sepium,Nesogordonia papaverifera,etc.The pest has been intercepted many times at quarantine ports in China,which is a potential threat of invasion to China.The taxonomic status,morphological characteristics,distribution,hosts,the morphological differences between Bostrychoplites species were illustrated,so as to simplify the difficulty of quarantine and identification of this pest,and provide some reference for its identification at frontier ports.
