Carrying the identification characteristics, the biological specimen of specific vectors is an important basis for a border port to correctly identify the vector in intercepted subjects. With the help of computer and network technology, biological samples of vectors can be digitalized, based on which a database with quick inquiry functions may be created to facilitate vector identification. This paper presents the importance of vector samples digitalization and summarizes the advances in digital biological specimens and related researches at home and abroad, indicating that collection of digital biological samples should include both text and image data of the specimen. The workflow suitable for vector sample digitalization is also discussed.

Objective To predict the potential distribution of the Western Treehole Mosquitoes, Aedes sierrensis (Ludlow, 1905) in China. Methods Genetic algorithm for rule-set production (GARP) was used for prediction of the potential distribution based  on  current  stable  distribution  of  Ae. sierrensis  derived  from  previous  literatures. Results The potential  distribution  of Ae. sierrensis covered most provinces in China, with the high-risk area located in the north and central part of China, including Xinjiang, Inner Mongolia, Ningxia, Shaanxi, Shanxi, Hebei, Beijing, Tianjin, Henan, Shandong, Liaoning, Jilin and Heilongjiang; the moderate?risk areas including Anhui, south of Hebei, southeast of Shandong, north of Hubei and northwest of Zhejiang; and the low-risk areas including Guizhou, Guangxi, Hunan, Chongqing, Hubei, Jiangxi, Fujian, Hainan and Taiwan. Conclusion Extensive potential distribution of Ae. sierrensis was identified in China with high risk levels, and thus risk management should be developed and deployed to prevent potential invasion of such mosquitoes.

【Abstract】 Under the support of asp program and structured query language（SQL） Server 2000 database management system, the information system on vector specimen was established by ADO data accessing technology and SQL query technology based on the data collected from the health department and the quarantine department. The system was made up of basic information database, specimen photo database and user information database. The information management system not only could take charge of the database, but also offered services to the ordinary users. It had good service function, which included that it had a friendly interface and it could inquire accurately and fuzzily. The system provided detailed information of vector specimens for the health/quarantine departments and the ordinary users, realizing the share of vector specimen information, which would be applied widely in the future.

Objective To study the pathogenic bacteria of Blattella germanica intercepted and captured in ports of Fujian province. Methods Bacteria were separated with selected culture medium, and then identified by PCR amplification, sequence analysis of 16S rRNA gene fragments. Results Five species of conditional pathogenic bacteria were detected, they were Klebsiella pneumoniae, Klebsiella ornithinolytica, Proteus vulgaris, Aeromonas veronii and Serratia marcescens based on the sequence homology more than 98% comparison with the published sequences. Pneumonia, abscess, peritonitis, meningitis, endocarditis and blood poisoning could be caused by these pathogenic bacteria. And one of them was deathful. Conclusion There are many conditional pathogenic bacteria in Blattella germanica intercepted and captured in ports of Fujian province.
