Influência climática e antrópica na abundância e riqueza de Calliphoridae (Diptera) em fragmento florestal da Reserva Biológica do Tinguá, RJ / Climatic and anthropic influence on the abundance and richness of Calliphoridae (Diptera) in a forest fragment in the Tinguá Biological Reserve, RJ, Brazil

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.

Raro caso de miíases por Cochliomyia hominivorax (Diptera:Calliphoridae) e Dermatobia hominis (Diptera: Oestridae) em paciente humano / A rare case of myiases by Cochliomyia hominivorax (Diptera: Calliphoridae)and Dermatobia hominis (Diptera: Oestridae) in a human patient

Miíase é uma doença causada por larvas de dípteros que se alimentam de tecidos vivo ou necrosado de hospedeiros. Paciente ingresso em hospital público, em péssimo estado clínico geral, exibia três lesões na cabeça com miíases, das quais foram retiradas 518 larvas de C. hominivorax e duas de D. hominis. Após aretirada de larvas, o paciente foi submetido a enxerto de pele.

Myiasis is a disease caused by an infection due to invasion of tissues or cavities of the body by larvae of dipterans insects that feed on live or necrotic tissue of the hosts. A patient was admitted to a public hospital, with a very bad general clinic state, presenting three lesions in the head, from which 518 larvae of C. hominivorax and two larvae of D. hominis were removed. After the removal of the larvae, the patient was submitted to a skin graft.
