SUMMARY:

The order Diptera is a diverse group of insects, has a cosmopolitan distribution and a high capacity to colonize different types of environments. In this order, there are muscoid representatives who have a high capacity to adapt to the environment modified by humans - synanthropic environments. Additionally, they have high medical and sanitary relevance, since they are related to the transmission of pathogens. In this context, it is known that anthropic environments (e.g. street fairs) with high human circulation and food supply can directly influence the composition and structure of muscoid dipterans assemblies, since it provides the facilities offers and abundance of food for flies. Therefore, the objective of this work was to evaluate the effect of street fairs on the composition and structure of assemblies of flies with sanitary importance in an urban environment in Toritama - Pernambuco. In addition, the presence of helminth eggs and protozoan cysts on the body surface of these flies was also analyzed. To this end, collections of dipterans were carried out in 2 commercial spots in the town of Toritama, and the flies were captured from traps called “Ratoeira Adesiva Cola Rato” before and after the occurrence of street fairs. In the parasitological analysis, the HPJ method was performed. Throughout the study, 7.780 specimens belonging to six Diptera families and a wealth of 14 species were collected. Muscidae was the most representative family with 96.98% of all flies caught, followed by Sarcophagidae (1.99%), Phoridae (0.53%), Calliphoridae (0.42%), Fanniidae (0.03%) and Stratiomyidae (0.02%). Muscidae was also the most diverse taxon with the registration of four species, followed by Sarcophagidae (3 spp.), Calliphoridae (2 spp.), Phoridae (2 spp.), Stratiomyidae (2 spp.) and Fanniidae (1 spp.). In addition, it was observed that the presence of the street fair influenced the structure of the assemblies, which was more abundant after the occurrence of the street fairs (H = 6.56; df = 1; P <0.01). Regarding the composition of the assemblies, 50% of the species were common to both treatments, with emphasis on the dominant species Musca domestica and Megaselia scalaris. No parasitological structures were found in the analyzed samples. Thus, the contribution of this study reveal that street fairs can modulate the structure and composition of fly assemblies in urban environments, including be able to offer health risks, considering that species of medical importance are related to this environment.
