Culex quinquefasciatus in Phitsanulok as a possible vector of nocturnally periodic Wuchereria bancrofti transmission in Myanmar immigrants.
The present study was undertaken in order to study whether Culex quinquefasciatus collected in Phitsanulok Province can be an insect host for the development of Wuchereria bancrofti larvae. W. bancrofti infected blood from Myanmar workers in Mae Sot, Tak Province was fed to mosquitoes by using the artificial membrane feeding. An infection of W. bancrofti was found with the highest density of L3 in the mosquito thorax on the 14th day after feeding. The infection rate also correlated to the density of microfilaria found in the donor's blood. Our results showed that Cx. quinquefasciatus in Phitsanulok is a possible vector of nocturnally periodic W. bancrofti.
