本文讨论了在白垩纪中、晚期,墨天牛属起源于非洲区,而在第三纪早、中期迁到东洋区后,一直有向北蔓延的趋势。中国墨天牛区系有两个来源,即本地和印度、中南半岛。中国大陆与台湾、日本、印度、中南半岛、西伯利亚、欧洲等地区均有密切的生物地理学关系。日本特有种(古北种)完全可能在中国北方林区造成危害,台湾特有种(东洋种)对大陆南方林区也潜在有威胁。印度、中南半岛的特有种也可能在中国大陆南方和台湾造成危害。在中国,危害较严重的5个种中,二斑墨天牛和松墨天牛属东洋种,云杉大墨天牛、云杉小墨天牛和云杉花墨天牛属古北种。
This paper discusses that Cretaceous originated in Africa during the Late Cretaceous and Late Cretaceous, and has been spreading northward since the Tertiary moved to the Toyo region in the early and middle stages. There are two sources for the Chinese ink-day cattle fauna, namely, the Indo-China and Indochina Peninsulas. Mainland China has close biogeographical relationship with Taiwan, Japan, India, Indochina Peninsula, Siberia and Europe. It is entirely possible that endemic species of Japan (ancient North Species) could cause harm in the forestlands of northern China. The endemic species of Taiwan (the species of the East Asia) also pose a potential threat to southern China’s forests. Indo-Indo-China endemic species may also cause harm in southern China and Taiwan. In China, the more serious damage to the five species, two spot Monochamus alternatus and Monochamus alternatus, Monochamus alternatus, Pterocarya xylostella and Picea versicolor, .
