SOP for impregnation of filter papers for testing insectiside susceptibility of adult mosquitoes in WHO tube tests

This standard operating procedure (SOP) describes the process for impregnating filter papers with insecticides and synergists to be used in WHO tube tests for testing insecticide susceptibility of adult mosquitoes. It is primarily aimed at researchers involved in the validation of discriminating concentrations, and is not intended for use by national programs for routine insecticide resistance monitoring.
