MOLECULAR VIBRATION AND INSECT ATTRACTION: DACUS OLEAE (DIPTERA: TEPHRITIDAE)

Abstract
Field tests demonstrated the attractiveness of several compounds to the olive fly, Dacus oleae Gmel.; a correlation with far infrared absorption bands was derived; and dl-homocysteine thiolactone hydrochloride was tested because of its conformity with this pattern. Field tests confirmed the predicted attractiveness of this and a few other compounds, and also an anti-attractant property in menthol and in butyl butyrate.
