In the Weeds

Eliminating Prosopis juliflora—an invasive, shrub-like tree that gives mosquitoes the sugar they need to survive—may reduce mosquito populations and malaria transmission, say researchers in Mali, West Africa.

Researchers examined 9 villages in the Bandiagara district of Mali over 8 days. Villages where the flowering branches of the tree were removed saw a nearly 70% decrease in mosquito population density, with sugar-fed females dropping from 73% to 15% and males from 77% to 10%.

The study concludes that controlling the growth of the invasive plants could reduce the mosquito population and curb transmission of malaria.
