Solar-powered mosquito traps that emit human odor as bait reduced the Anopheles funestus mosquito population by nearly 70% on the Kenyan island of Rusinga, in Lake Victoria, according to a recent report from an international group of researchers published in The Lancet.
Researchers conducted a stepped-wedge cluster-randomized trial that included all households in Rusinga Island. Between April 25, 2012, and March 23, 2015, they enrolled 34 041 participants from 4847 households and allocated these households to 81 clusters containing 50 or 51 neighboring households each. Installation of the mosquito traps was then carried out gradually cluster by cluster between June 3, 2013, and May 16, 2015; traps were ultimately installed in a total of 4358 households during this period. Because the traps require electricity and there is no electricity grid on the island, solar panels were installed on the houses.
