Abstract

Casual observations suggested that female Mediterranean fruit flies (Ceratitis capitata Wiedemann) exploit fruit wounds (including pre‐existing oviposition punctures) as oviposition sites. This behaviour was quantified under field conditions in a citrus grove on the Greek island of Chios. Fruit wounds influenced oviposition behaviour in three ways. First, females were more likely to land on oranges (Citrus sinensis) that were artificially wounded than into unwounded control oranges. Second, having landed, females were more likely to attempt oviposition into a wounded orange than into control oranges. Third, females that attempted oviposition into wounded oranges usually did so directly into or very near the wound. The diameter and depth of the wound significantly influenced the tendency for female flies to land on a fruit but not their propensity, having landed, to attempt oviposition in or near the wound. The significance of this behavior in nature and implications for management of the Mediterranean fruit fly are discussed. Utilisation des blessures des fruit par Ceratitis capitata lors de la ponte Des observations fortuites nous ont suggéré que C. capitata Weidemann utilise les blessures des fruits, y compris d'anciennes piqûres de ponte, pour déposer ses œufs. Ce comportement a été quantifié dans une orangeraie de l'île grecque de Chios. Les blessures des fruits influent sur la ponte de 3 façons. D'abord, les femelles atterrissent plus fréquemment sur les oranges, Citrus sinensis, artificiellement blessées que sur les fruits intacts. Ensuite, après atterrissage, les femelles tentent plus souvent de pondre sur une orange blessée que sur des oranges intactes. Enfin, les femelles pondent directement dans la blessure ou à proximité. Le diamètre et la profondeur de la blessure influent sur la tendance à l'atterrissage, mais non sur les tentatives de ponte dans la blessure ou près d'elle. La signification de ce comportement dans la nature et ses conséquences sur la lutte contre C. capitata sont discutées. 1989 The Netherlands Entomological Society
