A MOSQUITO NET FOR INSECTICIDE-RESISTANT MOSQUITO VECTORS OF MALARIA

Long-lasting insecticide-treated mosquito nets are the most widely used
intervention for preventing transmission of malaria by anopheline 
mosquitoes. Their effectiveness is threatened by the development
of resistance to pyrethroid insecticides enabling the mosquito to 
survive contact with the net. Olyset Duo is a new type of bed net
treated with pyrethroid and a new insecticide, pyriproxifen, that
disrupts the maturation of eggs in the ovaries of blood-fed 
mosquitoes. Ngufor and colleagues evaluated the capacity of the 
Olyset Duo net to control pyrethroid-resistant mosquitoes in 
laboratory tests and under household conditions in West Africa. 
The Olyset Duo net killed more pyrethroid-resistant mosquitoes 
than did the standard pyrethroid net and also sterilized 
any mosquitoes that survived exposure to the net. By preventing 
mosquito reproduction, the new net has the potential to reduce 
mosquito populations and malaria transmission in areas of high 
pyrethroid resistance.
