Abstract

Opius concolor Szépligeti is a parasite ofBactrocera oleae (Gmelin) and other Tephritid flies. Its development rate was studied with the Sharpe-DeMichele mathematical model, modified by Schoofieldet al. (1981), using the S.A.S. program elaborated by Wagneret al. (1984). This program chose a four parameter poikilotherm model with high temperatures inhibition. Duration of parasitoid development at seven constant temperatures ranged from 14.6±1.7 days at 28°C (males), to 77.2±5.5 days at 15°C (females). Male development was consistently found to be shorter than that of females. Low development threshold and degree-days needed to complete total development were determined with the “Regression Line” and “Thermal Summation” methods. Values (cumulated for both sexes) were found to be respectively 11.7°C and 11.8°C (low threshold), 255.9 and 251.9±16.8 days (thermal constant). Considerations on the possibility of establishingOpius concolor in northern and central Italian regions are discussed.

Résumé

Opius concolor est un parasitoïde deBactrocera oleae (Gmelin) et d’autres tephritidés. Sa vitesse de développement a été étudiée avec le modèle mathématique de Sharpe-DeMichele, modifié par Schoofield (1981), utilisant le programme S.A.S. élaboré par Wagneret al. (1984). Ce programme a choisi un modèle à quatre paramètres pour les poikilothermes avec inhibition aux températures élevées. La durée de développement du parasitoide sous sept différentes températures constantes est comprise entre 14,62±1,69 jours à 28 °C (mâles) et 77,25±5,5 jours à 15 °C (femelles). Le développement des mâles est nettement plus court que celui des femelles. Le seuil de développement et les degrés-jours nécessaires à un développement complet étaient déterminés par les méthodes de la « ligne de régression » et de la somme thermale. Les valeurs (pour les deux sexes cumulés) étaient respectivement de 11,7 °C et de 11,8 °C (seuil bas), 255,9 et 251,9 ± 16,77 jours (constante thermale). La possibilité d’acclimaterOpius concolor dans le nord et le centre de l’Italie est discutée.
