Abstract:
Filariasis mosquitoes and susceptibility of Cx. quinquefasciatus and Cx. vishnui to insecticides were investigated in September 2004 and May 2005 in Khanh Trung commune, Khanh Vinh district, Khanh Hoa province. Twenty two mosquito species belonging to 5 genus have been found, of which the primary vector of W.bancrofti filariasis was captured with a high density, while vectors of B.malayi was found in a lower density. A total of 805 mosquitoes of 6 species (An.barbumbrosus, An. vagus, Cx.fuscocephala, Cx.quinquefasciatus, Cx.tritaeniorhynchus and Cx. vishnui) were dissected. None of them were positive with microfilaria. Cx.quinquefasciatus was found highly resistant to lambdacyhalothrin, alphacypermethrin and malathion with the mortalities of 11 %, 21%, and 60%, respectively. Similarly, the mortalities of Cx.vishnui were 19.76%, 23.83% and 13%-17%, respectively.
