Abstract
CDC (Communicable Disease Center) light-traps were compared with human-bait collections as an alternative method for sampling malaria vectors in two villages of western Kenya. The numbers ofAnopheles funestusGiles andAnopheles gambiae sensu latoGiles in CDC light-trap collections were significantly correlated to the numbers caught in human-bait collections, but inAnopheles arabiensisPatton the two collections were not significantly correlated. Most of the female vectors collected in the traps were unfed. Parity ofA. arabiensiscollected in CDC light-traps (44.3%) was significantly lower than the rate obtained from females caught on human-bait (54.5%). Although CDC light-traps provide a cheap and convenient method for collecting vectors, further studies should nevertheless be undertaken to determine the influence of species-specific variation in the sizes and age-structure of collections because such variations can affect the epidemiological interpretation of the data.
