The Character of Mosquitoes Distribution and Relation with the Arbovirus in Xishuangbanna Prefecture,Yunnan Province

From July to August in 1981,1982,1983,1986,1987 and 1988, 34 508 adult female mosquitoes belonging to 34 species of 8 genera were captured from Jinghong,Menghai and Mengla Counties in Xishuangbanna Prefecture of Yunnan Province,China.During the night,the 21 species mosquitoes were collected in the rural stable and nearby regions and the superior mosquito species were Culex fuscocephalus and C.tritaeniorhynchus.During the day,the 25 species mosquitoes were collected in the bamboo forest and the superior mosquito species were Aedes annandalei and Ae.albopictus.Mosquitoes captured were examined by C6/36 cell method and suckling mouse method.Twenty five strains of Japanese encephalitis(JE)virus were isolated from C.tritaeniorhynchus(8 strains),C.whitmorei(4 strains),C.pseudovishnui(3 strains),C.annulus(1 strain),C.fuscocephalus(1 strain),Anopheles sinensis(3 strains),Ae.vexans(2 strains),Ae.albopictus(1 strain),Ae.lineatopennis(1 strain) and Mansonia uniformis(1 strain).Three strains of dengue type 4 virus,a strain of dengue tyep 3 virus and two strains of Chikungunya(CHIK) virus were isolated from Ae.albopictus.A strain of CHIK virus was isolated from C.tritaeniorhynchus.These results indicated that C.tritaeniorhynchus was the main transmitting vector of JE virus in Xishuangbanna,while C.whitmorei and C.pseudovishnui were also important transmitting vectors of JE virus,and Ae.albopictus was the mainly transmitting vector of dengue and CHIK viruses in Xishuangbanna.
