Susceptibility of Anopheles gambiae s.l. to the neonicotinoid insecticide clothianidin in eighteen sites located along the south-north transect of Benin.

ABSTRACT:

Background

The widespread resistance of malaria vectors to traditional neurotoxic insecticides has stimulated the search for new insecticide classes with novel modes of action. For that, the present study was designed to collect data on the susceptibility of field-collected Anopheles gambiae sensu lato (s.l.) to clothianidin, a neonicotinoid insecticide used in agriculture and that recently received WHO approval for use in indoor residual spraying.

Methods

An. gambiae s.l. were collected as larvae and pupae from 18 sites located along the south-north transect of Benin, and reared to adulthood. Female mosquitoes aged 2-5 days were exposed to clothianidin-impregnated papers (2% weight by volume (w/v) of SumiShield™ 50WG dissolved in distilled water). Due to the delayed action
