Abstract

Colonized mosquitoes of Culex quinquefasciatus (Haitian strain) and Aedes aegypti (Liverpool strain) were blood fed on a patas monkey (Erythrocebus patas) that had been experimentally infected with the Haitian strain of Wuchereria bancrofti and harbored a consistently low microfilaremia (1-3 mf per 20 mm3). Both species ingested more than twice the expected number of microfilariae (mf), i.e. 1.9 and 0.77 mf per mosquito, respectively. However, at 10-16 hours post ingestion only 4.2% of the mf had migrated from the blood meal in Cx. quinquefasciatus versus 20.7% in Ae. aegypti. Subsequently, only 3.5% of the ingested mf developed to the third stage in Cx. quinquefasciatus versus 56% in Ae. aegypti.
