“…Our results show that antennal olfactory receptors of male and female D. oleae adults are sensitive to 1,7-dioxaspiro (5.5) undecane, a-pinene, nonanal and ethyl dodecanoate, the four compounds constituting the female sex pheromone (Baker et al 1980, Mazomenos and Haniotakis 1981, Mazomenos et al 1981 as well as to p-cymene. The main pheromone component, which constitutes more than 50% of the female effluvium (Mazomenos and Haniotakis 1981), however, does not elicit the highest EAG response.…”

“…Among the female pheromone components the highest EAG response is evoked by nonanal. Nonanal is present in the female effluvium in amounts about ten times lower that the main pheromone component (Mazomenos and Haniotakis 1981). Studies in moths have shown that there is not always a positive correlation between the male EAG's and the relative amounts of the female pheromone components (Van Der Pers and Löfstedt in press).…”

“…This pheromone was found to be a blend of the following four substances: 1,7-dioxaspiro (5.5) undecane; a-pinene; nonanal and ethyl dodecanoate (Baker et al 1980, Mazomenos and Haniotakis 1981, Mazomenos et al 1981. 1,7-dioxaspyro (5.5) undecane is the major component of the blend on the basis of both quantity and biological activity.…”

Substances found in Dacus oleae (Gmelin) (Diptera: Tephritidae) male or female flies which have been reported as pheromones, i.e. elicit some form of biological activity in laboratory or field bioassays, were tested with the electroantennogram technique (EAG). Substances of non-insect origin were also tested as possible pheromone candidates. All substances of insect or non-insect origin elicited an EAG response to both sexes of lab-cultured or wild insects but 1,7 dioxaspiro [5,5] undecane, the major pheromone component, has a lower response threshold value than all other compounds. At the maximum stimulus concentration the response to nonanal reaches a value higher than that elicited by all other compounds. EAG responses to various compounds, after receptor adaptation to the major pheromone compound and nonanal, showed that these two compounds are detected by different sets of receptors. Other comments on the sensitivity and specificity of antennal receptors are also presented.
