Oviposition performance of tephritid polyphagous Anastrepha fraterculus and Ceratitis capitata during three periods of exposure to fruit

Year: 2022

Type: article

Abstract: Our study evaluated the oviposition behaviour of Anastrepha fraterculus (Wiedemann, 1830) and Ceratitis capitata (Wiedemann, 1824) in five fruit species. Apples, guavas, mangoes, peaches and tangerines were exposed to infestation for 6, 12 and 24 hours. Anastrepha fraterculus and C. capitata showed different oviposition behaviour in apples and tangerines and similar oviposition behaviour in guavas, mangoes and peaches. There was a positive correlation between infestation time and pupae/kg, as well as between pupae/fruit and the survival rate of the immature (pupal viability). In this study, we present discussions about the oviposition behaviour of flies and the host infestation index. This index can reflect the reproductive capacity that each fruit species offers for each fly species. Here, we see an adult recovery rate greater than 89% in the highest infestation index observed in guava (185 A. fraterculus per unit fruit) and peach (220 C. capitata per unit fruit). Understanding the reproductive capacity of each host can help with risk analysis and the management of fruit flies.
