Abstract

The control of mosquito vectors of malaria is largely based on insecticide applications, either on the inside walls of dwellings or on treated nets. For that reason, the surveillance of insecticide resistance in these species is essential for the definition of plans and strategies of malaria control. The purpose of this study was to determine the diagnostic doses of several insecticides used in public health for the main vectors of malaria in Colombia: Anopheles darlingi, A. albimanus and A. nuneztovari, using the methodology of impregnated bottles developed by the Centers for Disease Control and Prevention. Natural populations of the three species, submitted to low or no insecticide pressure, were selected with which bioassays were conducted to determine baseline susceptibility. Diagnostic doses (insecticide concentration and diagnostic time), or saturation curves, were established for the insecticides lambda-cyhalothrin, deltamethrin, fenitrothion, malathion and DDT for the three vectors; cyfluthrin, permethrin and propoxur for A. albimanus and A. darlingi, and etofenprox and bendiocarb for A. darlingi. The diagnostic doses determined in these susceptible populations will allow an evaluation of the status of insecticide resistance of the main malaria vectors across their distribution in Colombia, strengthening the resistance surveillance system and facilitating decision making for a more appropriate use of insecticides to control malaria in the country.
