The prevalence of Anopheles (Diptera: Culicidae) mosquitoes in Sekong Province, Lao PDR in relation to malaria transmission

摘要: Summary A longitudinal study was conducted on the prevalence of Anopheles in three malaria endemic villages Sekong province, southern region Lao PDR, from August 2000 to October 2001. All night, human landing collections took place and April 2001, blood smears were taken for parasites during same period. Mosquitoes tested sporozoite antigen using enzyme-linked immunosorbent assay. In (wet season) 2001 (dry ovaries mosquitoes examined parity. A total 16 species caught sites which An. dirus A, maculatus sl jeyporiensis positive sporozoites. The entomological inoculation rate (EIR) ranged 0.06 0.25. There a good correlation between EIR vectorial capacity wet season, especially Pai Mai where also high seasons (11.8 10.53). showed ambivalence their choice feeding as approximately 50% attacked man indoors an equal proportion outdoors. An main vector Mai. parous did not significantly differ dry although it higher season. Takaio parasite 8.7% 37.1% vector, risk infection 0.85 season while 0.99 Toumgno found only 2000. However, 9.69 20.4% equally Cattle present close houses all this might be contributory factor malaria.
