Studies on the ecology of A. gambiae s.s. and the transmission of malaria were undertaken in a high rainfall forested area in southern Sierra Leone. A. gambiae s.s., identified by chromosomal techniques as the Forest form, was the only malaria vector in the study village. Rice fields or swamps were not favoured larval sites for this species; 'breeding' mainly occurred in temporary pools. The mean annual sporozoite rate of A. gambiae s.s. determined by ELISA was 3.9%. Pyrethrum spray, human-bait and exit trap collections, as well as identification of mosquito blood-meals using the ELISA method, showed that the forest chromosomal form of A. gambiae s.s. was highly anthropophagic and exophilic.
