Abstract

Proceratophrys boiei is an endemic cycloramphid anuran inhabiting the leaf litter of Atlantic rainforests in Southeastern Brazil. We analyzed the whole digestive tract of 38 individuals of Proceratophrys boiei collected in two Atlantic Rainforest areas in the state of Rio de Janeiro, Brazil, to study the diet composition and the helminth fauna associated with this species. The main food items in P. boiei's diet were Coleoptera, Orthoptera and Blattaria. Five nematode species were found: Aplectana delirae, Cosmocerca parva, Oxyascaris oxyascaris, Physaloptera sp. (larval stage only) and an unidentified nematode. Overall prevalence was 71% and mean infection intensity was 7.3 ± 5.8 neatodes per individual.

摘要

博氏原角蟾是一种特有的环褶蛙科无尾目动物，栖息于巴西东南部大西洋雨林的落叶层中。我们分析了从巴西里约热内卢州两个大西洋雨林地区采集的38只博氏原角蟾的整个消化道，以研究其饮食组成以及与该物种相关的蠕虫动物区系。博氏原角蟾饮食中的主要食物种类为鞘翅目、直翅目和蜚蠊目。发现了五种线虫物种：德利拉无尾感器线虫、小宇宙线虫、奥氏蛔虫、仅幼虫阶段的泡翼线虫属以及一种未鉴定的线虫。总体感染率为71%，平均感染强度为每只个体7.3±5.8条线虫。
