Abstract

AbstractThe sibling species composition of Anopheles farauti sensu lato in the Torres Strait islands was determined by cellulose acetate electrophoresis of isoenzymes. An. farauti No. 1 was widespread and the predominant species on all islands surveyed. An. farauti No. 2 was recorded on the southern islands of Horn and Prince of Wales. An. farauti No. 3 was not collected. Maximum biting activity of An. farauti No. 1 occurred around the middle of the night; insufficient An. farauti No. 2 were collected to determine biting activity. The majority of An. hilli fed before midnight although pre‐dawn activity peaks were also observed. In simultaneous indoor and outdoor collections, 11–64% of An. farauti No. 1 and 6–40% of An. hilli were caught indoors.
