A study carried out along the South-North transect in Benin has shown the impacts of the use of chemical pesticides in agricultural for crop protection in the selection and spread of resistance of Anopheles gambiae s.l. to insecticides

Indeed, the knock-down resistance frequency found in An. gambiae populations from the cotton and vegetable farming fields where farmers used a high dose of chemical pesticides, is significantly higher than the one from areas with low or no use of pesticides (food crop and rice growing areas).

The acetylcholinesterase mutation was also found, but only in An. gambiae populations from the areas where high dose of pesticides were used for pests control

These findings confirm once again the role of agriculture in the selection and spread of resistance of Anopheles gambiae s.l. to insecticides

Key words: agriculture; Insecticides; Resistance; Anopheles gambiae; Benin.
