Abstract
The objective of this study was to evaluate the influence of wing bands and the behavior of Anastrepha fraterculus in the presence of Megafreya sutrix. The first experiment used specimens of M. sutrix (n = 40), 20 males and 20 females of A. fraterculus and Musca domestica. The second experiment used 20 individuals of M. sutrix (10 males and 10 females) and 120 of A. fraterculus (20 males and 20 females) for each treatment. Marks were made on the wings of the flies: a group with painted wing bands (n = 40) with their wings fully painted; another with highlighted wing bands (n = 40) and normal bands (n = 40). Recordings were made for 15 min or until the fly was preyed upon. The analyses were performed through observation of the recordings and Chi-square test with Yates correction for continuity. The values found for predation of A. fraterculus were significant when compared to M. domestica when evaluating the predation factor, showing that, A. fraterculus is less predated than M. domestica. It was found that the wing patterns did not influence the predatory behavior of M. sutrix.
