Existing malaria vector control methods (e.g. nets and insecticide sprays) primarily target mosquitoes that enter or attempt to enter human dwellings, yet mosquitoes also obtain significant proportions of essential resources outdoors. Fredros Okumu of Ifakara Health Institute in Tanzania and his co-investigators therefore proposed the use of strategically-located outdoor vector control devices. In this project's Phase I research, the team created new and easy-to-use outdoor methods for luring, trapping and killing mosquitoes, including major African malaria vectors.
