Blood-feeding requirements of the mosquito: geographical variation in Aedes taeniorhynchus

Wild poplulations of Aedes taeniorhynchus were polymorphic for the diets required for ovarian development. In Aedes taeniorhynchus populations from mangrove swamps, most females possessed the capacity to produce eggs on a blood-free diet. But where the grassy salt marsh was the mosquito's principal habitat,most females lacked this capacity. Both kinds of females could utiliZe a blood meal for egg production.
