The World Health Organization (WHO) has provisionally recommended the use of a new generation of insecticide-treated mosquito nets — a step forward for the prevention of malaria. Interceptor G2, developed by the German chemical company BASF, is treated with a blend of two classes of insecticide.
According to articles published in the Malaria Journal and PLoS ONE, the first is alpha-cypermethrin — known as a pyrethroid, this is the insecticide currently added to mosquito nets. Interceptor G2 also incorporates chlorfenapyr, a type of insecticide typically used in agriculture and to combat pests in urban environments —it had not previously been used to prevent disease.
“We observed that Interceptor G2 systematically eradicated a significant proportion, around 75 per cent, of malaria vectors that had become resistant to pyrethroids,” Corine Ngufor, a researcher at the London School of Hygiene and Tropical Medicine (LSHTM) in the UK, and one of the authors of the study, told SciDev.Net.
