“…Despite the short time and fast sampling effort (Two hours), the richness ( q =0) here reported (8 species) obtained in only two hours of sampling is similar with comparable Andean forensic entomological studies of flies associated with decomposed corpses during 144 hours in the fresh and bloated stage (9 species) (Grisales et al, 2010) and during 244 hours in the central range of Colombia (10 species) (Montoya-G et al, 2009). Coverage diversity data here obtained are in agreement with the study of de Sousa et al (2020) in Amazonia, where they report the highest values of diversity estimated in the preserved environments; they also pointed that necrophagous flies respond differentially to the anthropic activity especially to cattle ranching. In other words, a more preserve environment displays higher values of diversity, and inversely the more urbanized or disturbed environments exhibit agthe lowest values.…”

A necrophagous flies ensemble (Diptera, Calyptratae) was rapidly assessed in four coverages of an anthropogenic landscape in the east range of the Colombian Andes. Ninety-seven individuals belonging to eight species were collected in only two hours of sampling. The highest diversity values and the occurrence of asynanthropic flies in the forest under conservation management may indicate a positive effect of the natural restoration process in the area assessed. Grassland, rural and urban coverages were similarly low in diversity and composition. A brief discussion about the flies’ bionomy and their environment association is offered. Necrophagous flies ensembles by coverage behave as an indicator of the anthropic impact on the landscape.

The Anthropocene is characterised by pervasive human‐inflicted impacts on a broad range of biota, including insects. In 2019, we reviewed scientific literature quantifying the prevalence and magnitude of insect declines in recent time. Here, drawing upon 40 additional long‐term studies, we add evidence that is consistent with our earlier review and some other reviews on the fate of insect populations globally. New data for Greenland, northern Africa, South America, eastern Asia and Australia complement studies from Europe and North America. Temporal trends in insect populations are now derived from 100 long‐term studies and refer mainly to the past three or four decades (median 33 years). Data from the 10 major insect taxonomic orders indicate that an average 37% of species are declining in numbers, while populations of 18% species are increasing; the latter taxa mainly involve agricultural herbivores and nuisance pests. Population changes are more pronounced among aquatic insect communities, where 42% of species are declining and 29% increasing. Such changes result in a decrease in biomass across taxa, except for Heteroptera. Changes in species richness and diversity indices are inconsistent and do not reflect intraspecific population changes over time. These trends are observed irrespective of taxon, geography or methodological approach, although a lack of long‐term monitoring records prevents a proper assessment for tropical regions.

“…Peckia (S.) lambens is native to the southern United States of America (USA), several Caribbean islands, nearly all of South America, and has been introduced to the Cook Islands and French Polynesia. This widespread distribution is most likely due to the species' high ecological plasticity, which allowed it to colonize a wide range of environments, including heavily populated ones (Camargo et al 2018, Sousa et al 2020; furthermore, its larvae consume a variety of food sources. They can be insect parasitoids, predators of dying scorpions and insects, cause myiasis in birds and mammals, and scavengers of dead vertebrates and invertebrates.…”

Scavengers flesh flies (Diptera, Sarcophagidae) from two phytophysiognomies in the state of Maranhão, Northeastern of Brazil

2021

Flesh flies (Sarcophagidae) have been found in a wide range of natural and anthropogenic environments, from forests to deserts. The state of Maranhão, located in Northeastern Brazil, has a diverse phytogeography, but few faunistic studies have been conducted in this area. Therefore, the objective of this study was to inventory species of Sarcophagidae and compare abundance patterns between the Cerrado (savanna-like vegetation) and riparian forests in the municipality of Codó, state of Maranhão. Twelve sampling events were carried out from the second half of 2015 to the first half of 2017. This resulted in 3,220 specimens, 27.15% of which were males, from nine genera and 27 species. A total of 491 specimens (16 species) were collected in the Cerrado, and 383 specimens (21 species) in the riparian forest. Peckia (Sarcodexia) lambens (Wiedemann) was the most abundant species (56,18% of the specimens sampled), followed by Peckia (Peckia) pexata (Wulp) (13%); Peckia (Euboettcheria) collusor (Curran & Walley) (13%), and Peckia (Peckia) chrysostoma Wiedemann (10%). Only P. (E.) collusor was found in greater abundance in the Cerrado. Oxysarcodexia angrensis (Lopes), Peckia (Peckia) enderleini (Engel), and Retrocitomiya andina Lopes are all new records to Maranhão and the entire Northeast Region of Brazil. Titanogrypa (Cuculomyia) albuquerquei (Lopes) is also a new to Maranhão.
