“…The traps were adapted from Hwang & Turner (2005) and are described in detail in Battán‐Horenstein et al . (2016). Within each site, the two traps were separated by a minimum distance of 20 m and a maximum distance of 40 m. The summer traps were installed for five consecutive days, while the winter traps were installed for 10 consecutive days, in both cases once a month in each season during 3 months per season and year.…”

“…It is one of the largest cities in the country being the second most populous in Argentina. The socio‐historical and demographic development of the city resulted in a landscape characterized by a highly developed urban core and suburban outskirts with a decrease in impervious surfaces on the periphery (Battán‐Horenstein et al ., 2016). In the framework of increasing interest in urban insect biodiversity, we aim to develop studies on flesh flies by determining which species are associated with measurable urban features (impervious surfaces or vegetation cover).…”

The urbanization process affects the structure of insect communities, favouring biotic homogenization processes by promoting adequate conditions for the establishment of synanthropic species. Considering the scarce knowledge about the ecology of Neotropical sarcophagids, we compared the flesh fly community from two different urban zones in two contrasting seasons and examined the response of the Sarcophagidae assemblage to landscape and microhabitat variables. Adult flies were collected in 13 sites with two traps (total number of traps 26) baited with 200 g of hydrated bone meal. A total of 2312 adult sarcophagids were collected belonging to 27 species; Oxysarcodexia paulistanensis (Mattos, 1919) represented >48% of the total sample. The local factor of insolation explained both the abundance and species richness of sarcophagids, collections being higher and richer in traps exposed to sunlight compared with traps placed in the shade regardless of the season. Richness was also affected by the environment, being higher in traps exposed in suburban rather than urban sites. The combination of these factors (sub‐urban environment and availability of open areas) could explain the Sarcophagidae assemblage. The average number of sarcophagid species collected was related to the season, providing a good opportunity to assess the temporal variability of this family in the region.

“…(), amongst other. In addition, researchers have been investigating the diversity and seasonal dynamics of some saprophagous flies using different types of bait (Mulieri et al ., ; Patitucci et al ., ; Battán‐Horenstein et al ., ; Dufek et al ., ; Olea et al ., ). Differences in the performance of baited traps indicate that the type of decomposing organic matter can affect the assembly of species that are attracted, which could be expected because they may differ in terms of both their nutrient composition and their physical and chemical properties (Hanski, ).…”

“…Sarcophagidae were more attracted to faeces than to viscera, whereas Calliphoridae showed the opposite pattern. In Cordoba, lower numbers of flies were captured with bone meal compared with chicken viscera or cow liver; the group of species attracted to cow liver and bone meal were subsets of the species collected with chicken viscera (Battán‐Horenstein et al ., ; Battan‐Horenstein & Gleiser, ; Vilte et al ., ). These studies mainly compared faeces, carrion or similar organic matter of animal origin, and other processed waste such as processed food leftovers were not considered.…”

1. Direct consumption of organic matter by the saprophagous larvae provides the ecosystem with a fundamental service by recycling nutrients and reducing exposure to decomposing matter. The present study aimed to assess the functional role of saprophagous flies in the mass loss of different types of decomposing organic matter.2. Two types of common urban waste were used to measure the role of flies in reducing organic matter: chicken viscera (chicken) and a mixture of flour and uncooked eggs (flour and eggs), representing leftover food. Ten traps baited with each substrate, under field conditions, allowed fly access (exposed to flies) and three traps from each substrate did not (unexposed controls); adult flies entering the traps or emerging from the substrates and substrate mass loss were recorded.3. Species from Calliphoridae, Sarcophagidae, Muscidae, and Fanniidae families were collected mainly in traps baited with chicken, with Phoridae being the most abundant in traps with flour and eggs as bait. A significantly richer (P < 0.05) assemblage of fly species accessed the traps baited with chicken viscera (21 species) compared with those emerging (11 species), whereas similar numbers of species accessed (n = 5) or emerged (n = 1) from traps baited with flour and eggs (average richness accessing 7.97, emerging 2.83). Chicken substrate mass loss and species richness were positively related (r = 0.56, P = 0.001). In traps where richness was larger than 10 species, the substrates were reduced by more than 85% of their initial weight compared with unexposed controls, which lost 30%. Substrate mass loss significantly increased with the abundance of flies (r = 0.73, P < 0.0001).4. The results of the present study support the functional role of saprophagous species diversity on the decomposition rates of organic matter, reinforcing the negative consequences of loss or gain of species in modified landscapes and for ecosystem function.

“…Most studies on urban Diptera communities are usually focused on groups of economic importance (Stonehouse et al, 1998;Smiley et al, 2004;Taylor et al, 2012) or forensic-sanitary interest, like Culicidae (Alto & Juliano, 2001;Ludueña-Almeida et al, 2004;Gleiser & Zalazar, 2010;Mangudo et al, 2018), or saprophagous flies (Battán Horenstein et al, 2014, 2016Dufek et al, 2019;Vilte et al, 2020), but relatively few of them were focused on the effects of seasonality on fly communities outside these groups of interest (e.g. Beckett, 1992;Valente-Gaieski, 2019).…”

Variaciones estacionales de los ensambles de Diptera en espacios verdes urbanos de la ciudad de Córdoba, Argentina: misma riqueza, distinta composición RESUMEN. La estacionalidad puede tener una influencia directa en la estructuración de las comunidades de insectos debido a las distintas preferencias o tolerancias a las condiciones climáticas de las especies que las componen. El objetivo de este estudio fue evaluar los cambios estacionales en dípteros adultos en espacios verdes urbanos. Los dípteros fueron colectados sobre la vegetación con una G-VAC (aspiradora) en espacios verdes urbanos de la ciudad de Córdoba, Argentina, durante el verano e invierno de 2014. Globalmente, la abundancia de dípteros fue mayor en verano que en invierno, mientras que la riqueza fue similar en ambas estaciones. Sin embargo, la riqueza por sitio fue significativamente menor en invierno, reflejando una distribución más heterogénea y un alto recambio de familias en esta estación. La composición de familias y/o sus abundancias relativas difirieron entre estaciones, reflejando la preferencia estacional de varias familias de Diptera en esta región templada del hemisferio sur. PALABRAS CLAVE. Diversidad. Estacionalidad. Insecta. Paisaje urbano.ABSTRACT. Seasonality can have a direct influence on the structuring of insect communities due to different preferences or tolerances to the climatic conditions of the species that compose them. The aim of this study was to evaluate seasonal changes in adult Diptera assemblages of urban green patches in a southern temperate region. Dipterans were sampled from vegetation with a G-VAC (aspirator) in urban green patches in Córdoba city, Argentina, during the summer and winter of 2014. Overall, dipterans were more abundant in summer than in winter but globally, their richness was similar. However, richness per site was significantly lower in the winter, reflecting a heterogeneous distribution and higher family turnover during this season. Family composition and/or their relative abundances differed between seasons, reflecting the seasonal segregation of several Diptera families in this temperate region of the southern hemisphere.
