THE INFLUENCE OF AGE, NUTRITION AND TIME OF DAY ON THE RESPONSIVENESS OF MALE DACUS OPILIAE TO THE SYNTHETIC LURE, METHYL EUGENOL

Abstract

Several factors which may influence the responsiveness of male D. opiliae Drew & Hardy (Diptera: Tephritidae) to the lure methyl eugenol, were studied in the laboratory. Males did not respond immediately after emergence and the time course of the development of responsiveness was correlated with the attainment of reproductive maturity, as indicated by readiness to mate. Once developed, responsiveness was maintained to at least 3 months of age. The development of full responsiveness depended on access to protein‐aceous food, but continuous access was not necessary. Males displayed a daily cycle of responsiveness which was inversely related to the cycle of mating behaviour. Ingestion of methyl eugenol appeared to reduce subsequent responsiveness, but continuous long exposure to the odour, without ingestion, did not.RÉSUMÉInfluence de l'âge, de l'alimentation et de l'heure d'expérience sur les réponses des males de Dacus opiliae au méthyl‐eugénol synthétiqueDivers facteurs susceptibles d'influencer les réponses à l'attractif sexuel méthyl‐eugénol des mâles de Dacus opiliae Drew & Hardy (Diptera: Tephritidae) ont été étudiés au laboratoire. Aucune réponse n'est enregistrée chez les mâles au cours des 3 premiers jours qui suivent l'émergence (25°, 75% HR). L'intensité des réponses augmente ensuite progressivement jusqu'à atteindre un maximum le 8è jour. Cette progression suit un cours parallèle au développement sexuel mesuré par l'aptitude des mâles à s'accoupler. Une fois acquise, la sensibilité au méthyl‐eugénol se maintient pendant au moins trois mois. L'intensité maximale des réponses n'est atteinte que si une alimentation protéinique — même intermittente — est fournie. L'intensité des réponses au méthyl‐eugénol ne varie guère entre 8 et 18 h; elle est plus faible au crépuscule (19 h), seul moment où les mâles de D. opiliae sont sexuellement actifs. Le cycle quotidien des réponses à l'attractif correspond donc à l'inverse de celui de l'activité sexuelle. L'ingestion de méthyl‐eugénol semble diminuer les réponses, mais une exposition continue à l'odeur sans ingestion d'attractif ne les change pas.
