Isolation of Japanese encephalitis virus from four species of Aedes mosquito in Yunnan Province

  • Available online: 05 March 1999
  • A total of 19 367 adult female mosquitoes belonging to 16 species of Aedes genus were captured from nine countries, south western part of Yunnan Province, China, and were examined by C6/36 cell method and suckling mouse method. Two strains of Japanese encephalitis (JE) virus were isolated from 6491 (185 pools) Aedes albopictus , two strains of JE virus were isolated from 1605 (50 pools) Ae. vexans, two strains of JE virus were isolated from 772 (23 pools) Ae. lineatopennis, and a strain of JE virus was isolated from 103 (4 pools) Ae. assamensis. Isolation of JE virus was negative to other 12 species of Aedes mosquitoes. Ae. albopictus was the superior species of mosquitoes in bamboo forest. These results indicated that Ae. albopictus from Yunnan has a potential role in the maintenance and transmission of JE virus in nature. Ae. vexans, Ae. lineatopennis and Ae. assamensis are also considered to be transmitting vector of JE virus in Yunnan.

    • 1. 

    Abstract: A total of 19 367 adult female mosquitoes belonging to 16 species of Aedes genus were captured from nine countries, south western part of Yunnan Province, China, and were examined by C6/36 cell method and suckling mouse method. Two strains of Japanese encephalitis (JE) virus were isolated from 6491 (185 pools) Aedes albopictus , two strains of JE virus were isolated from 1605 (50 pools) Ae. vexans, two strains of JE virus were isolated from 772 (23 pools) Ae. lineatopennis, and a strain of JE virus was isolated from 103 (4 pools) Ae. assamensis. Isolation of JE virus was negative to other 12 species of Aedes mosquitoes. Ae. albopictus was the superior species of mosquitoes in bamboo forest. These results indicated that Ae. albopictus from Yunnan has a potential role in the maintenance and transmission of JE virus in nature. Ae. vexans, Ae. lineatopennis and Ae. assamensis are also considered to be transmitting vector of JE virus in Yunnan.
