A survey of Calliphoridae and Mesembrinellidae (Diptera) in semideciduous seasonal forest, Paraná, Brazil

Abstract

Calliphoridae and Mesembrinellidae include Diptera species that are good indicators of changes in forest environments. The present work aimed to inventory the Calliphoridae and Mesembrinellidae in Ilha Grande National Park and correlate the abundance of these organisms with environmental variables. Adult dipterans were collected during two expeditions in 2019 using two sampling methods, a Malaise trap and baited traps, distributed on two islands in the park. During the study, 1,007 individuals of 12 species of Calliphoridae and four species of Mesembrinellidae were collected. Family Calliphoridae was more abundant (97.12%). The abundance of native species showed a strong negative correlation with the abundance of the genus Chrysomya. Rodrigues Island (Island I) had higher diversity levels and no species of Chrysomya were recorded in this area, which may indicate a greater degree of environmental preservation. The results indicate that human action in natural environments can negatively impact species diversity, as found in Ilha Grande National Park that, historically, was partially occupied and is still in the process of regeneration.

Synanthropy and ecological aspects of Calliphoridae and Mesembrinellidae (Diptera: Oestroidea) in three ecological areas in Rio de Janeiro State, Brazil

“…Laneela nigripes and Mesembrinella bellardiana were considered the most abundant in less anthropic areas. These data corroborate with [ 24 , 27 , 28 ]. Several studies over the decades portray the Mesembrinellidae family as asynanthrope, being found exclusively in forest areas or deeper spots in forest fragments [ 29 ].…”

“…nigrofacialis were the only Calliphoridae species found exclusively in the forest environment. The genus Paralucilia is common in preserved environments [ 23 , 24 ]. In this study, P .…”

Seasonal distribution of Calliphoridae and Mesenbrinellidae (Diptera) associated with the decomposition of a clothed animal model in a forest reserve in the Central Amazon

“…This finding may indicate greater potential for these species as forensic indicators for forested areas, due to the large number of immatures developing on the corpses and of visiting adults. No immature forms of C. albiceps were observed in the present study, however, a high number of adults was collected, which may be due to difficulty in competing with forest species since C. albiceps is a species that presents a high degree of synanthropy (Souza et al 2021). This also demonstrates that the adult species of Diptera collected from the corpses may not represent the true larval fauna that develops there.…”

“…The most abundant species sampled was Chrysomya albiceps (38%), followed by Hemilucilia semidiaphana (25%), which are considered synanthropic in several regions of Brazil (Souza et al 2021). These species were collected in the urban area of Manaus in an experiment with swine corpses (Barros-Souza and Ferreira-Keppler 2013), and in a forest reserve surrounded by strong anthropic pressure in a peri-urban area (Ururahy-Rodrigues et al al.…”

“…In addition, the seasonal distribution of Calliphoridae and Mesembrinellidae is strongly influenced by variations in climatic conditions, and each species can react in different ways. These are not the only factors that act on the population dynamics of dipterans, which can even be affected by the relationship among the species themselves (Souza et al 2021).…”
