在巴西的自然界中，对南美果蝇 A. fraterculus (Wiedemann) 在有果和无果的寄主树以及无果的非寄主树 [Eugenia uniflora、E. brasiliensis、Citrus sinensis、Diospyros kaki、Annona、Castanea、Psidium] 上的昼夜模式和活动位置进行了定量观察，结果揭示了以下内容。黎明时分（约 0600 小时），两性都在非寄主树和寄主树顶部附近的叶子底面上休息。性活动（男性呼叫）开始于 .apprx。 0700 时并于 1100 时停止。它发生在非寄主和寄主上，所有观察到的交配起始和交配对仅发生在高大的非寄主树的顶部附近。摄食和产卵开始于.apprx。 0800时，上午至下午3时左右为高峰，1800时前结束。取食几乎只发生在渗出汁液的成熟寄主果实上，产卵几乎只发生在未成熟的寄主果实上。 1800 小时（黄昏）及之后观察到的所有苍蝇要么在树顶附近的叶子底面上休息，要么向树顶飞行。讨论了有关 A. fraterculus 的发现与自然界中研究的其他实蝇科的昼夜模式和活动位置的关系。
Quantitative results of observations in nature in Brazil of the diel pattern and location of activities of a South American fruit fly, A. fraterculus (Wiedemann), on host trees with and without fruit, and on nonhost trees without fruit [Eugenia uniflora, E. brasiliensis, Citrus sinensis, Diospyros kaki, Annona, Castanea, Psidium], revealed the following. At dawn (.apprx. 0600 h), both sexes were at rest on the bottom surface of leaves near the tops of nonhost and host trees. Sexual activity (male calling) began at .apprx. 0700 h and ceased before 1100 h. It occurred on nonhosts as well as hosts, with all observed copulation initiations and mating pairs occurring only near the top of a tall nonhost tree. Feeding and oviposition began at .apprx. 0800 h, peaked from midmorning to midafternoon, and ended before 1800 h. Feeding occurred almost exclusively on ripe host fruits exuding juice, oviposition occurred almost exclusively on unripe host fruits. All flies observed at 1800 h (dusk) and afterward were either at rest on the bottom surface of leaves near the tops of trees or were in flight toward tree tops. The findings on A. fraterculus are discussed in relation to the diel pattern and location of activities of other Tephritidae studied in nature.
