Abstract

The influence of body size of Anopheles gambiae s.s., Anopheles arabiensis, Anopheles merus, and Anopheles funestus on the transmission of Plasmodium falciparum was studied at 3 sites along the Kenyan coast. Adult mosquitoes were collected inside houses by pyrethrum spray collection (PSC) from April to September 2001. Wing length was measured microscopically to the nearest 0.01 mm as an index of mosquito body size. The P. falciparum circumsporozoite protein (CSP) was detected by enzyme-linked immunosorbent assay technique. A total of 1,715 anopheline mosquitoes were collected, of which 785 (45.77%) were An. gambiae s.s., 54 (3.15%) An. arabiensis, An. merus 27 (1.57%), and 849 (49.5%) were An. funestus. The mean wing length for An. gambiae s.s. was 2.94 mm and that of An. funestus was 2.50 mm. There was no site-to-site variation in the body size of An. gambiae or An. funestus. There was no significant difference in wing length between sporozoite-infected and uninfected An. gambiae s.s., and the same was found for An. funestus. At the 3 rural coastal sites in Kenya, the efficiency of malaria parasite transmission does not appear to be influenced by variation in vector body size.
