Insecticide coating effective against mosquitoes

A new method of applying insecticide to netting has proved 100% effective against some strains of mosquito, an international study reports.

The electrostatic coating allows the netting to carry much higher doses of insecticide.
In experiments, the coating killed off many more mosquitoes than usual.
Dutch researchers, writing in Proceedings of the National Academy of Sciences, say this could help control diseases such as malaria.
Insecticide resistance in mosquitoes has become a significant problem in many parts of the world where malaria is endemic.
It is thought that water-based spray insecticides and bed nets, which often contain low levels of insecticide, don't always kill the mosquitoes, allowing them to develop resistance.
In this study, researchers from the Netherlands used a charged surface, originally developed for trapping airborne pollen, and applied insecticide to it.
