Guideline for Evaluating Insecticide Resistance in Vectors Using the CDC Bottle Bioassay

The CDC bottle bioassay determines if a particular formulation (combination of the active ingredient in the insecticide and inactive ingredients) is able to kill an insect vector, such as a mosquito, at a specific location at a given time. It can detect resistance to insecticides in mosquitoes and other insects. The technique is simple, rapid, and economical, compared with alternatives. The results can help guide the choice of insecticide used for spraying.
