Objective To determine the species composition and distribution of mosquitoes and the pathogens carried in Shanghai, China, and to provide a scientific basis for establishment of local preventive measures for mosquitoes and mosquito-borne diseases. Methods Related literature of the last 20 years (1993-2013) was collected, from which relevant information was extracted, and the mosquito species and distribution and the pathogens carried by them in different investigation sites in Shanghai were analyzed. Results Anopheles sinensis, Aedes albopictus, Culex tritaeniorhynchus, Cx. pipiens pallens, and Armigeres subalbatus were the most common mosquito species in Shanghai. The diversity of species in airports and ports was significantly higher than that in other areas. Japanese encephalitis virus genotypes Ⅰ and Ⅲ were both prevalent among the mosquitoes in Shanghai. Conclusion Airports and ports are the main entrance points of mosquito invasion. There is a potential risk of dengue virus and West Nile virus when considering a large number of appropriate vectors in Shanghai. The investigation and monitoring of mosquitoes and their pathogens should be strengthened in Shanghai.

【Abstract】 Objective To study medical mollusc in Beijing region.  Methods All medical molluscan specimens were collated and analyzed, which were collected from Beijing and deposited in the Zoological Museum, Institute of Zoology, Chinese Academy of Sciences, based on field work, literature, museum records and expert assistant.  Results A total of 29 important species of molluscs related to 48 kinds of parasites in Beijing region had been identified, which belonged to 10 families, 2 Class.  Conclusion Molluscs played a key role in transmitting parasitic diseases as intermediate host. There were no reports on medical molluscan diversity, distribution and its parasites in Beijing region for more than thirty years. This study showed that so many medical mollusc could survive in Beijing region and it should be paid more attention for department of public health management.
