Levantamento faunístico de populações de Calliphoridae e Muscidae (Diptera) provenientes de quatro ambientes no município de Salvador, BA

Abstract

The class Insecta is one of the most diverse in the animal kingdom, and these animals spread across environments. Due to it, there is great interest in studying this class, especially in the Order Diptera, since many species can cause economic damage in the agricultural, act as vectors of disease or cause myiasis in humans and other animals, and also by the possibility of using data these bodies within the forensic through the use of forensic entomology. Knowing the biology, the place of occurrence and behavior of the species involved in the decomposition process, it is possible to establish where the body was first colonized, and estimating time of death (IPM). For this requires previous collections, with the aim of knowledge of insect species scavengers of each region, since the populations of flies can vary according to the environments and places. Accordingly, in the present study was a survey of wildlife dipterofauna present in the city of Salvador, and analyzed for abiotic and biotic factors that could influence directly or indirectly on the population dynamics of these insects from four different environments. A total 11,962 specimens were collected belonging to the families Calliphoridae and Muscidae (Diptera). Differences in relation to the abundance and species diversity were observed when taken into consideration environmental factors and physical conditions of each site sampled. Among the most abundant species are Synthesiomyia nudiseta (n = 3013), Lucilia eximia (n = 2688), Chrysomya albiceps (n = 1914) and Chrysomya megacephala (n = 1693), all environments and the full period of this study was 12 months. Thus, one can verify that the urban environment appears to contribute to the maintenance of species diversity in Salvador, in association with environmental factors, especially precipitation. Was also prepared an identification key to diagnosis to help identify the species most frequently present in this region.
