Technical Abstract: Ceratitis capitata, the Mediterranean fruit fly, is one of the most serious agricultural pests worldwide, responsible for substantial reduction in fruit and vegetable yields, resulting in billions of dollars of economic loss. The aim of this study was to identify effective attractants for C. capitata and disrupt the ‘disadvantage matrix’ associated with conventional insecticide control: expense, pesticide resistance, and harm to the environment and non-target beneficial insects. A series of 29 structurally-related natural and synthetic aromatic compounds were screened for bioactivity using lab bioassays and electroantennography (EAG). No-choice bioassays identified phenyllactic acid, estragole, o-eugenol, and 2-allylphenol as promising attractants for males. Binary choice bioassays showed o-eugenol to be the most attractive. In general, strong EAG responses were elicited by the same compounds that were observed to be attractive in the bioassays. Additionally, EAG analysis identified 2 compounds that elicited higher than expected olfactory responses; these require further study to determine their biological relevance. This study demonstrated that there are key structural features (specific functional groups attached to the aromatic ring) associated with attraction, information that will help direct future research on development of improved lures for Mediterranean fruit fly.
