Calliphoridae (Diptera, Oestroidea) associados à decomposição cadavérica de roedores em ambiente urbano no município de Campo Grande, MS

Abstract

Calliphoridae is one of the families of the order Diptera, made up of around 1000 species distributed worldwide. Some species are used in forensic entomology, as these are one of the first organisms to colonize the corpse. This study aims to identify the biodiversity and succession of dipteran fauna from the Calliphoridae family present throughout the decomposition process of a rodent carcass in an urban environment in the municipality of Campo Grande, MS. To carry out the collections, a trap was installed in the Núcleo Habitacional Buriti neighborhood for a period of 12 consecutive days throughout the month of June 2021. A rat carcass was used as an attractant, kept in natural conditions inside the trap. In total, 1666 individuals belonging to four species were collected, placed in two genera, Chrysomya and Lucilia. It was concluded that the biodiversity of Calliphoridae collected can be considered satisfactory and that their activity in the carcass can be divided into some stages, with the period from the fifth to the eighth day being the moment of greatest activity and fauna succession.
