| Resumo: | ABSTRACT
Insects perform many important functions in nature that help maintain balance in
ecosystems. Muscomorpha diptera would be no different, they contribute directly to
the ecosystem balance by accelerating the recycling of organic matter and allowing
nutrients to be reused. This study aimed to evaluate the attractiveness of different
substrates on the assembly of sarcosaprophagous dipterans in a preserved fragment
of the Atlantic Forest. The collections were carried out in the State Park Dunas do
Natal - RN and in a fragment of forest located inside the federal University of Rio
Grande do Norte during the months of July and August 2019. For the collection of
insects, suspended traps made from from a pet bottle, which were baited with five
different types of substrates: fermented mango and cashew, decomposed chicken
and fish liver, and fresh human feces. A total of 1,499 adults from eight families were
collected. Calliphoridae was the most representative family with (32.49%) of the
collected specimens, followed by Phoridae (16.54%), Fannidae (15.88%) and
Sarcophagidae (13.88%). The other families: Drosophilidae, Muscidae, Micropezidae
and Ulidiidae correspond to (21.21%) of the total of individuals. Among the
substrates, chicken liver and human feces were the most attractive substrates
represented (47.63%) and (23.08%) of adult flies, respectively. The substrates that
proved to be less efficient in the locality were cashew (9.74%), fish (12.88%) and
mango with (6.67%) of adults. The results also revealed that Lucilia eximia was the
most abundant species in the study areas. The present work also contributed to the
enrichment of the list of Diperas species known in the state of RN. If new records
were found for the Muscidae families: Cariocamia maculatus (Snyder, 1951) and
Helina sp; Sarcophagidae: Oxysarcodexia diana (Lopes, 1933), O. bakeri (Aldrich,
1916), Sarcofahrtiopsis cuneata (Townsend, 1935), Sarcophaga (Liopygia) crispola ()
and Tricharaea (Sarcophagula) canuta (Wulp, 1896) and also the record of 1896) family Micropezidae. |
