“…illucens (Stratiomyidae). This corresponds to results reported by several authors, according to which a decrease in diversity is attributable to depredation by other Diptera species at the larval stage, also influencing their abundance (Labud et al 2003). Presence of H. illucens larvae, reported in other studies as consumers of decomposing organic matter and responsible for decreases of M. domestica, is clear evidence of the role of H. illucens in controlling M. domestica (Furman 1959apud Williams 2005.…”

Insects associated with the composting process of solid urban waste separated at the source ABSTRACT. Insects associated with the composting process of solid urban waste separated at the source. Sarcosaprophagous macroinvertebrates (earthworms, termites and a number of Diptera larvae) enhance changes in the physical and chemical properties of organic matter during degradation and stabilization processes in composting, causing a decrease in the molecular weights of compounds. This activity makes these organisms excellent recyclers of organic matter. This article evaluates the succession of insects associated with the decomposition of solid urban waste separated at the source. The study was carried out in the city of Medellin, Colombia. A total of 11,732 individuals were determined, belonging to the classes Insecta and Arachnida. Species of three orders of Insecta were identified, Diptera, Coleoptera and Hymenoptera. Diptera corresponding to 98.5% of the total, was the most abundant and diverse group, with 16 families (Calliphoridae, Drosophilidae, Psychodidae, Fanniidae, Muscidae, Milichiidae, Ulidiidae, Scatopsidae, Sepsidae, Sphaeroceridae, Heleomyzidae, Stratiomyidae, Syrphidae, Phoridae, Tephritidae and Curtonotidae) followed by Coleoptera with five families (Carabidae, Staphylinidae, Ptiliidae, Hydrophilidae and Phalacaridae). Three stages were observed during the composting process, allowing species associated with each stage to be identified. Other species were also present throughout the whole process. In terms of number of species, Diptera was the most important group observed, particularly Ornidia obesa, considered a highly invasive species, and Hermetia illuscens, both reported as beneficial for decomposition of organic matter.KEYWORDS.

“…The establishment of cosmopolitan species, together with reductions of endemic species, increases the phylogenetic similarity, a process referred to as taxonomic homogenization. Most species detected in the present study were exotic and considered either eusynanthropic or hemisynanthropic (Labud et al 2003), supporting the homogenization of the blowfly fauna in urban environments, as has been observed in other bioclimatic regions (Mariluis et al 2008, Labud et al 2003. Lucilia eximia and L. cluvia are a Nearctic and a Neotropical species, respectively, frequently found in rural and urban sites and that breed primarily in carcasses but also in rotten fruit and urban garbage (Madeira et al 1989).…”

Diversity of Necrophagous Blowfly (Diptera: Calliphoridae) of Medical and Veterinary Importance in Urban Environments in Córdoba (Argentina)

The complex nature of urban environments can have different effects on species diversity and composition. The aim of this work was to characterize the assemblage of Calliphoridae regarding its richness, abundance, and synanthropy in Córdoba City, Argentina. Three sampling sites differing in their distance to the border of the city and degree of urbanization were selected. In each site, collections were carried out with 12 traps baited with cow liver (200 g per trap) that were operated for five consecutive days during three different times of the year, in April, June and August 2013. A total of 341 adult calliphorids from nine species,, Calliphora vicina Robineau-Desvoidy, Sarconesia chlorogaster (Wiedemann), Chrysomya albiceps (Wiedemann), C. megacephala (Fabricius) and C. chloropyga (Wiedemann) were collected. Lucilia sericata was the most abundant species followed by C. vicina. Species diversity, composition and abundance changed between sites, richness being lowest at the most urbanized site. All species are cosmopolitan except Sarconesia chlorogaster, whose distribution is restricted to South America. These results are consistent with a homogenization of the fauna in urban environments.Key words. Diptera, Calliphoridae, urban landscape, diversity. RESUMENLa complejidad de los entornos urbanos puede tener diferentes efectos en la diversidad y la composición de especies. El objetivo de este trabajo fue caracterizar el conjunto de Calliphoridae en cuanto a su riqueza, abundancia y sinantropía en la ciudad de Córdoba, Argentina. Se seleccionaron tres sitios de muestreo que difieren tanto en la distancia al borde o límite de la ciudad como en la intensidad de la urbanización. En cada sitio se colocaron 12 trampas cebadas con hígado de vaca (200 g por trampa) que permanecieron durante cinco días consecutivos durante tres momentos diferentes del año, en abril, junio y agosto de 2013. Se recolectó un total de 341 califóridas adultos pertenecientes a nueve especies, Lucilia sericata (Meigen), L. eximia (Wiedemann),

“…Dewatered materials may be considered more economically viable for land application, relative to LMBs, since reduced water content will reduce the cost of transportation of the waste to field sites (Wakeman et al, 1976). However, dewatering can effectively concentrate contaminant constituents relative to their liquid or wastewater counterparts that have much lower total solids contents (Withers et al, 2001; Mantovi et al, 2005), and moreover, dewatered biosolids may enhance vector attraction (e.g., insects) (USEPA, 1995; Labud et al, 2003), and can be more odorous than slurry or liquid municipal biosolids (Zhang and Westerman, 1997; Janiec, 2006).…”

Nitrogen, Phosphorus, and Bacteria Tile and Groundwater Quality Following Direct Injection of Dewatered Municipal Biosolids into Soil

et al. 2009

Application of municipal biosolids (sewage) to agricultural land is a common practice to improve soil physical quality and fertility. Th e chosen method of land application can have a strong impact on the extent of adjacent water contamination by nutrients and bacteria. Dewatered municipal biosolids (DMB) were applied to silt-clay loam experimental fi eld plots in Ontario, Canada using two application methods: (i) surface spreading followed by shallow incorporation (SS) and (ii) a newly developed implement that directly injects DMB into the topsoil (DI). Th e objective of this study was to compare N, P, and bacteria quality of tile drainage and shallow groundwater associated with each land application technique. Th ere were no signifi cant diff erences (P > 0.05) in N, P, and bacteria tile mass loads among the application treatments for time periods <100 d postapplication, when the greatest peak loads and peak tile water concentrations were observed. Both land application treatments caused groundwater Escherichia coli contamination to at least 1.2 m depth below surface after the fi rst postapplication rainfall event, and NO 3 -N contamination to at least 2.0 m depth below surface. Th e DI treatment did, however, have signifi cantly (P < 0.05) higher tile mass loads of total Kjeldahl N (TKN), total phosphorus (TP), E. coli, Enterococci, and Clostridium perfringens relative to the SS treatment for time periods >100 d postapplication. Nevertheless, relative to tile effl uent data collected <100 d postapplication (no application treatment diff erences), peak loads, and concentrations during this time were, overall, considerably lower for both treatments. Th is fi nding, along with no signifi cant diff erences in N, P, and bacteria groundwater concentrations among the application treatments, and that the direct injection technique could potentially reduce vector attraction problems and odor, suggests that the direct injection technique should be considered a dewatered municipal biosolid land application option.
