Abstract:
Electroantennography (EAG) is a simple, yet powerful technique that can be used to indicate that chemical compounds are detected by mosquito antennae. When coupled with gas chromatography (GC), it allows for the identification of detectable compounds within complex mixtures, including those in plant and animal headspaces that might influence mosquito behavior. EAGs and GC-EAGs reveal compounds that can be tested in behavioral assays with the goal of developing new repellents or attractants for mosquito control.
