Myiasis is defined as the infestation of living or necrotic tissues of vertebrates by dipteran larvae. In amphibians, it can be caused by fly larvae belonging to families Calliphoridae, Chloropidae, Muscidae, and Sarcophagidae. In this study, we report new records and infestation intensity of myiasis in anurans from two localities of the Atlantic Forest in southern Brazil, and also present a list with myiasis caused by flesh fly Sarcophagidae species in anurans of the Neotropical region. For this, we surveyed anuran communities during two breeding seasons, examined for myiasis signs, and when positive collected the specimens. We found infested individuals of 13 anurans of seven species. Different Sarcophagidae larva morphotypes were collected, and two of them emerged as adult flies of Lepidodexia (Notochaeta) fumipennis and Peckia (Sarcodexia) lambens, which were both found in the tree frog Bokermannohyla circumdata. We compiled 21 cases of myiasis in anurans in the Neotropical region from the literature reviewed. This data indicated that hosts of different lineages and modes of life can be affected and that death is often fast. The diversity of myiasis-causing flies in anurans in nature is probably a lot greater than expected, especially if we consider that the encounters are occasional, but at relatively high intensities, can cause rapid deaths.
蝇蛆病是指双翅目幼虫寄生在脊椎动物活体或坏死组织中的现象。在两栖动物中，它可能是由蝇科、丽蝇科、蝇科和麻蝇科的幼虫引起的。在这项研究中，我们报告了巴西南部大西洋森林两个地区蛙类的蝇蛆病新记录和感染强度，并列出了新热带地区蛙类中由肉蝇科 Sarcophagidae 物种引起的蝇蛆病的清单。为此，我们在两个繁殖季节调查了蛙类群落，检查了蝇蛆病的迹象，并在阳性时收集了标本。我们发现了 13 种 7 种蛙类的受感染个体。收集到了不同的 Sarcophagidae 幼虫形态型，其中两种孵化成了 Lepidodexia (Notochaeta) fumipennis 和 Peckia (Sarcodexia) lambens 的成年蝇，这两种蝇都在树蛙 Bokermannohyla circumdata 中发现。我们从文献综述中汇编了新热带地区 21 例蛙类蝇蛆病。这些数据表明，不同谱系和生活方式的宿主都可能受到影响，而且死亡通常很快。在自然界中，引起蛙类蝇蛆病的苍蝇的多样性可能比预期的要大得多，尤其是考虑到这种接触是偶然的，但强度相对较高，可能导致快速死亡。
