中国动物虫媒病毒主要传播媒介库蠓种类及其分布

库蠓（双翅目：蠓科）是一种重要的医学和兽医学媒介昆虫,能通过叮咬动物和人传播蓝舌病病毒（bluetongue virus, BTV）、施马伦贝格病毒（Schmallenberg virus, SBV）、奥罗波克病毒（Oropouche virus, OROV）等多种病毒,危害动物和人类健康,造成重大经济损失。全国34个省级行政区中,除了北京和澳门,其余都有库蠓分布的报道。我国现记载的库蠓属有12个亚属368种,分布在云南的库蠓种类最多,其中原野库蠓（C.homotomus）的分布最广。能传播或潜在具有传播病毒能力的库蠓至少有42种,其中我国有20种,在北京、天津、香港、澳门以外的各省（市、自治区）均有分布。为进一步了解传播虫媒病毒的库蠓种类及其分布情况,促进我国蠓传动物疾病的预防和控制,本文对我国动物病毒媒介库蠓的种类和分布情况进行综述,为动物虫媒病毒的研究提供依据。     

The importance of geographical pathology.

Three different forms of cancer--the Burkitt lymphoma, nasopharyngeal carcinoma and skin cancer--are discussed in their relation to geographical distribution, the possible role of viruses, and genetic predisposition. Certain general conclusions in regard to cancer follow from these discussions. It is stated firmly that cancer is not a disease but a tissue manifestation which has not only many different presentations but also many different complex causes which consequently will need many different forms of treatment. A comparison of geographical differences is of immense value.
