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.
