This study estimates the susceptibility to organophosphates of four species of Culicidae mosquitoes — Culex pipiens, Ochlerotatus detritus, Ochlerotatus caspius and Anopheles labranchiae — collected in the marshes of Smir (northwest of Morocco).

The five organophosphates studied (temephos, malathion, fenthion, fenitrothion, and chlorpyrifos) are frequently used for mosquito control in Morocco.

The sensitivity tests (bioassays) show that Culex pipiens, Ochlerotatus detritus and Ochlerotatus caspius are resistant to temephos and Culex pipiens and Ochlerotatus detritus to chlorpyrifos.

The results of this study can serve as a database for developing a strategy to manage mosquito resistance to insecticides in this region.
