小蠹

Bark beetle is one of approximately 220 genera with 6,000 species of beetles in the family Scolytidae, which is the most common and important pest infesting forest.

小蠹虫是鞘翅目小蠹科昆虫的总称，全世界约有220属，6000种左右，是林木害虫中一个极重要类群。

As the bark beetle damages in the trunk or the inner bark of trees,it can be easily transmitted during international trade in timber and wooden packing material,so the quarantine of bark beetle is very important.

Feasibility study on application of DNA bar-coding technology in molecular identification of ScolytideaCO I gene of 15 bark beetle species collected from different regions and host is studied to discuss the feasibility of application of DNA bar-coding technology in Scolytidea molecular identification.

基于线粒体COⅠ基因的DNA条形码技术应用于小蠹科昆虫分子鉴定的可行性研究通过对采自不同地区、不同寄主的15个小蠹虫样本的线粒体COⅠ基因研究，对基于线粒体COⅠ基因的DNA条形码技术应用于小蠹科昆虫分子鉴定的可行性进行了探讨。

Generally,to solve the practical problem of bark beetle quarantine in imported timber and wooden packing material,we carried out the research of semiochemicals-trap application,morphological and molecular identification of bark beetle in this project,and the results would contribute to improving the whole level of bark beetle quarantine.

本研究从解决进境木材及木质包装材料携带小蠹虫检疫的实际问题出发，进行了信息化合物引诱技术在小蠹虫检疫中的应用，以及检疫性小蠹科昆虫形态与分子鉴定等一系列研究，为小蠹虫整体检疫水平的提高奠定了理论与实践基础。

Further more,at present,there are tess systemic professional references about intercepted and captured bark beetle during quarantine in China,so it\'s time to establish a database of morphologic characteristics of bark beetle for quarantine in order to help quarantine inspection officer correctly identify them.Together with DNA bar-coding technique,the database will greatly promote the ability in identifying intercepted and captured bark beetle during quarantine.

此外，由于小蠹科昆虫种类繁多，目前对检疫截获小蠹虫的鉴定工作存在较大困难，且比较系统地反映我国进口货物中截获小蠹虫的专业资料较少，因此，急需建立针对我国进口木材中小蠹虫检疫用的形态图谱以加强检疫人员对其的识别；并通过分子生物学分类技术的研究，辅以DNA条形码技术以提高对其的鉴定水平。

The research showed that:(1) Dendroctonus micans and Ips nitidus responded to pheromone of low concentration,which demonstrated that the olfactory response threshold of these two species to pheromone was very low,and the response value increased with the concentration.

研究结果表明：(1)云杉大小蠹与光臀八齿小蠹均能对其较低浓度的虫体信息素成分产生嗅觉反应，说明其对虫体信息素的感受阈值较低；且随着虫体信息素浓度的增大，反应值增加。

The present paper mostly concerned was the T. piniperda which was discovered in Yunnan Province, the research advances on Pinus yunnanensis volatiles and using the volatiles to trap T. yunnanensis were reviewed, the successful experiences of using plant volatiles to monitor and control Scolytidae was briefly summarized.

针对云南纵坑切梢小蠹，综述了云南松挥发性化学成分的研究现状及利用各种挥发性成分诱集云南纵坑切梢小蠹的研究进展，同时简要介绍了国内外其他地区利用植物挥发性化学物质监测和防治小蠹类害虫的成功经验。

Expert consultation system for the bark bettles toted by imported wood including importing timber pest identification subsystem, import timber pest's multimedia database, It is comparatively systematic in the foreign timber quarantine field in our country , overall research relevant rudimentary knowledge , identification theory , working practice. The knowledge of this system was obtained through synthesizing existing publication and documents and materials both at home and abroad and the related experts , especially description of the identification character that summarized the working experience of decades at ports, it get the main identification character ,user who grasp two or three key characteristics can identify insect pests . There is very strong practicability.

小蠹科昆虫辅助鉴定系统包括小蠹科害虫鉴定子系统，小蠹科害虫多媒体数据库，是我国对外木材检疫领域较为系统全面的研究了相关基础知识、检疫鉴定理论、结合一线工作实践、通过综合国内外现有的出版物及文献资料和访问相关领域的专家而得，尤其是鉴定特征的描述，是总结了口岸几十年的工作经验，抓住了主要鉴定特征，用户只需掌握两三个关键特征就可以实现对害虫的快速鉴定，有很强的实用性。
