[Investigation on mosquitoes and mosquito-borne viruses in Dehong prefecture, Yunnan province, 2007 and 2010].

Objective: To investigate the distribution patterns of mosquito and mosquito-borne viruses in Dehong prefecture, Yunnan province, China.

Methods: Mosquito samples were collected using the mosquito traps from five counties of Dehong prefecture on July, 2007 and 2010. Mosquito were cell cultured for viral isolation, and positive isolates were identified using RT-PCR and sequence analysis.

Mosquitoes of Western Yunnan Province, China: seasonal abundance, diversity, and arbovirus associations.

Objective: The western borderland between Yunnan Province, China, and Myanmar is characterized by a climate that facilitates year-round production of mosquitoes. Numerous mosquito-transmitted viruses, including Japanese encephalitis virus circulate in this area. This project was to describe seasonal patterns in mosquito species abundance and arbovirus activity in the mosquito populations.
