“…Interestingly, the absence of species from the genus Chrysomya was observed in this study, contradicting our previous hypothesis that species of this genus would be among the most abundant since they are commonly found and dominant in other environments in Pernambuco (Vasconcelos et al 2015;Carmo and Vasconcelos 2016;Barbosa et al 2017;Oliveira and Vasconcelos 2020). The absence of species of this genus may be related to the type of trap used in the study.…”

Diptera have high capacity to adapt to anthropized environments and they present high medical and sanitary relevance, since they are related to pathogens transmission and myiasis causing. In this context, it is known that anthropic environments (e.g., street markets) with high human circulation and food supply can directly influence the composition and structure of muscoid dipterans assemblages. The aim of this work was to evaluate the effect of street markets on the composition and structure of assemblages of flies with sanitary importance in an urban environment of Toritama city, Pernambuco state, Brazil. The flies were captured using adhesive mousetrap “Cola Rato” before and after the occurrence of free markets. A total of 7,780 specimens belonging to six families and 14 species were collected. Muscidae was the most representative and diverse family, with 96.98% of all flies captured and four species. We observed that the assemblages were more abundant after the occurrence of the street markets (H = 6.56; df = 1; P < 0.01). Regarding the composition of the assemblies, 50% of the species were common to both treatments, with emphasis on the dominant species Musca domestica and Megaselia scalaris. This study reveals that free markets can modulate the structure and composition of flies’ assemblages in urban environments, including being able to offer health risks, considering that species of medical importance are related to this environment.

“…Data on the geographical distribution, seasonal occurrence and response to environmental factors are essential to subsidize protocols for the estimation of the minimum post-mortem interval and provide inferences about the site of death based on entomological evidence. Recent studies confirm the establishment of exotic Calliphoridae species of the genus Chrysomya in the Caatinga (Oliveira and Vasconcelos, 2020), and the ability of Sarcophagidae species (e.g., Blaesoxipha (Gigantotheca) stallengi (Lahille, 1907)) to outdo competitors in the colonization of animal baits (Barbosa et al, 2019). The extent to which these ecological features affect their likelihood as cadaver colonizers in rural areas in the semi-arid region is unknown.…”

“…Adult dipterans were collected using suspended traps (120 cm above ground) baited with 150 g of sardine or bovine spleen, previously exposed in environmental temperature for 24 h without access of insects (Oliveira and Vasconcelos, 2020). In each experimental area, we established one grid composed of 12 traps distant 20 m from each other, which were exposed in the field for 48 hours, following previous studies that evidenced the independence of samples (Vasconcelos et al, 2015).…”

Increase on intensive monocultures is an important threat to Caatinga biodiversity decrease. The use of chemical insecticides directly affects insect natural enemies of crops, but also non-target species. We aimed to test whether the diversity of sarcosaprophagous flies would be affected by agricultural management (conventional and organic). Adult dipterans were collected monthly, from July 2015 to January 2016, using a grid composed of 12 suspended traps distant 20 m from each other, baited with 150 g of sardine or bovine spleen, in each type of management. We first calculated α-diversity by Hill numbers, then evaluated the difference of diversity metrics by ANOVA. We also graphically visualise the species composition distribution by NMDS. We recorded a total of 4,651 specimens of 15 Calliphoridae and Sarcophagidae species. Chrysomya spp. were the dominant species (93.7% of all blowflies). Sarcophagidae species were sampled in low abundance, but with exclusive presence of some species in each treatment (e.g. B laesoxipha stallengi and Ravinia belforti in organic management). Although there was no difference on sarcosaprophagous fly diversity between treatments, we demonstrate empirically that mango plantations in the Caatinga harbour diverse and abundant assemblages of sarcosaprophagous dipterans, whose richness of species is comparable to other ecosystems such as rainforests and urban areas. Our results expand the known geographical range for forensically relevant species by providing a checklist of sarcosaprophagous dipterans that can thrive in agroecosystems in the Caatinga and, potentially, colonize cadavers disposed in that type of environment.

Variation in the community composition of blow flies (Diptera: Calliphoridae) in neighboring deserts within Joshua Tree National Park

Joshua Tree National Park (JOTR) in southern California offers a unique opportunity to explore insect biodiversity across 2 distinct desert ecosystems: the lower-elevation Sonoran Desert and the higher-elevation Mojave Desert. In these harsh environments, many blow flies (Diptera: Calliphoridae) serve as important decomposers, feeding on animal waste and decomposing tissue. Some blow fly species, notably non-native species, are associated with human activity, which underscores the need to study their communities in JOTR, where annual visitation has reached 3 million. This study investigated the community composition of blow flies across the park and assessed the impact of visitor activity on blow fly communities in JOTR. Sampling from 2021 to 2023 using traps baited with squid carcasses revealed higher blow fly diversity in the Mojave Desert relative to the Sonoran Desert, in contrast to previous insect and vegetation surveys within the park. Across the park, blow fly community composition (i.e., β-diversity) differed by season. Blow fly abundance, richness, and diversity were similar between low- and high-visitor activity sites. However, more non-native species were collected in areas of low visitor activity, suggesting regular waste removal practices in high-visitation sites might limit their ability to complete development as secondary colonizers. This study is the first to characterize blow fly communities in Joshua Tree National Park. These findings demonstrate that blow fly communities reflect previously established park boundaries and underscore the importance of waste management practices in reducing the spread of non-native species throughout the park.
