Chlorfenapyr – a new approach against resistant mosquitoes

Chlorfenapyr is a completely new insecticide class for public health. It controls malaria-carrying mosquitoes that are resistant to currently used insecticides. It belongs to the pyrrole class of chemistry and has an entirely different mode of action to the other WHO-recommended insecticides. It works by disrupting the insect’s ability to produce energy. But how exactly does it work? Watch BASF's film to find out. Long-lasting insecticide-treated mosquito nets and indoor residual sprays are the cornerstones of malaria prevention, particularly in sub-Saharan Africa. But 60 countries have already reported resistance to at least one class of insecticide used in them. In 2017, BASF received an interim recommendation from the WHO for Interceptor® G2, a long-lasting insecticide-treated mosquito net based on chlorfenapyr that can now be used to combat resistant mosquitoes. This is the first WHO recommendation for a product based on a new insecticide class in more than 30 years.
