Abstract
|
|
|
Four species of common household mosquitoes have been chosen for a series of experimental infection with Wuchereria bancrofti on Kin-men (Quemoy) Islands in the autumn and winter seasons.
Culex p. fatigans was re-confirmed as the only suitable mosquito host species. The infection rate 80% and 93%, and the infective rate of 53 % and 79% were found respectively under the low(67.8°F) and high (80. 5°F) temperature conditions.
Culex tritaeniorhynchus was found infected only with the immature (stage I and II) larvae, the infection rate being 31%. Four late 2nd-stage larvae were also found in 2 mosquitoes on the 13th and 15th day after blood feeding. However, this species is not considered of any importance as a vector of Wuchereria bancrofti.
Armigeres subalbatus and Aedes albopictus were found not infected; only exsheathed microfilariae were seen. On this observation, these two species did not seem to take any part in the transmission of Bancroftian filariasis.
