The entomological parasitological and socio-economic aspects of bancroftian filariasis were investigated in three wards of Colombo city, namey Mahawatta, Grandpass South and Kollupitiya The resting densities of Cx. quinquefasciatus which is the main vectory of bancroftian filariasis in Sri Lanka were 188.25, 53.58 and 33.74 C/MH in Mahawatta, Grandpass South and Kollupitiya respectively. The infection rates and infective rates of Cx. quinquefasciatus were 1.96 and 0.05 in Mahawatta, 1.62 and o.2 in Grandpass South and o.00 in Kollupitiya respectively. The mean sex ratio(male:female) of Cx. quinquefasciatus ranged from 1:0.5 to 1:6.32, the average being 1:3.08. of all the resting female mosquitoes collected from all the three wards, 96.35 were Cx, quinquefasciatus. of the total beetding places of Cx. quinquefasciatus, 65.85 were from Mahawatta while 31.71 and 2.44 were located in Grandpass South and Kollupitiya respectively. Damaged septic pits comprised of 55.3 of the breeding places while 19.2 and 10.6 consisted of cement drains and earth drains respectively. The parasitological investigations which were conducted to detect microfilariae of wuchereria bancrofti in the human population showed that the mf rate for Mahawatta, Grandpass South and Kollupitiya were 3.03, o.94 and o.oo respectively....en-USUniversity of Colombo, UC(SCI): Sri Lanka HELLIS NetworkFilariasisWuchereria bancroftiFilariasis-epidemiologyFilariasis-parasitologyThesis
