A new weapon against mosquitoes
The mosquito's fondness for plant nectar is being used to trick it into gorging itself with an insecticide - called Vectrax - which mimics the sweet-smelling scents of the nectar it usually feeds on. A successful trial has recently been held in several villages in Tanzania. Agenor Mafra-Neto is a Brazilian chemical ecologist, and head of ISCA Technologies in the US, which has developed this new anti-mosquito product.
