A method employing ANOVA is presented to quantify man-mosquito contact at Kowanyama, based on human bait collections indoors in light, indoors in darkness and outdoors in darkness. No shifts in feeding behavior were noted during the transitional, dry or wet seasons of 1974-75. Anopheles bancroftii fed in significantly greater numbers indoors in darkness; An. amictus, An. annulipes, An. farauti, An. meraukensis, Aedes normanensis, Ae. kochi, Ae. lineatopennis, Ae. vigilax and Culex annulirostris fed outdoors; Mansonia uniformis fed equally well in the 3 situations tested whereas Cx. quinquefasciatus primarily fed indoors.
