title: [Climatic and anthropic influence on the abundance and richness of Calliphoridae (Diptera) in a forest fragment in the Tinguá Biological Reserve, RJ, Brazil].
abstract: Monthly collections were made using two traps 5 m apart exposed for 48h, containing sardines and installed at points: A at the edge (500 m from the entrance of the Reserve); B 1200 m from the entrance and 1000 m inside the forest; and C 1700 m from the entrance and 500 m inside the forest. The purpose was to evaluate the abundance and richness of calliphorid species as a function of the environmental conditions using Pearson's correlation, compare the richness of the areas using ANOVA and Tukey's test, compare the abundances of the areas by the Kruskal-Wallis test, and also assess the possible influence of the anthropic presence. Rare, intermediary and common species were identified. The collection totalized 8515 Calliphoridae belonging to 26 species, with a predominance of females. None of the 13 species considered common presented a correlation between abundance and temperature: only Cochliomyia hominivorax (Coquerel) and Chrysomya megacephala (Fabricius) were correlated with humidity and only Mesembrinella semihyalina Mello with precipitation. This parameter was the only climatic variable correlated with richness. The greatest abundance and richness of calliphorids occurred in September 2006. From the 13 common species, seven were considered synanthropic, indicating the effect of anthropic action in this site.
