BASF has received a recommendation from the World Health Organization (WHO) for Interceptor G2, a long-lasting insecticide-treated mosquito net (LN) based on chlorfenapyr. Chlorfenapyr is a completely new insecticide class for combating mosquitoes for public health. This is the first WHO recommendation for a product based on a new insecticide class in more than 30 years.

Working with the Innovative Vector Control Consortium (IVCC) and the London School of Hygiene & Tropical Medicine in a collaboration lasting over a decade, BASF’s scientists successfully repurposed chlorfenapyr to be effective on mosquito nets and meet stringent WHO performance thresholds for public health.

Able to coat polyester netting with a long-lasting formulation

Dave Malone, IVCC Technical Manager, said “The collaboration with BASF gave us access to an insecticide with a rare combination of attributes: New to public health, effective against resistant mosquitoes, and able to coat polyester netting with a long-lasting formulation.” A second chlorfenapyr product, an indoor residual spray named Sylando 240SC, is also in the final phases of WHO evaluation.

About chlorfenapyr

Chlorfenapyr was derived by isolating a toxin from the Streptomyces fumanus actinomycete bacterium. It is new to the public health market, but has been used in agriculture and urban pest control, including in homes and food handling areas, worldwide since 1995. Chlorfenapyr belongs to the pyrrole class of chemistry and has an entirely different mode of action from current WHO-approved insecticides for public health. It works by disrupting the insect’s ability to produce energy. This makes it unlikely to show cross-resistance in mosquitoes that are resistant to currently registered public health insecticides.
