Technical Abstract: Tephritid fruit flies are major pests worldwide, but infestation is difficult to detect since the larval stages are concealed within host fruits. Using grapefruit infested with the Caribbean fruit fly, we evaluated gas chromatography (GC) as a tool for detection of hidden infestation. We found several GC peaks potentially diagnostic for larval-infested citrus. If infested commodities consistently release unique chemical profiles, this "signature" may provide the basis for rapid, sensitive screening protocols.
