“…This study is the first report for Colombia on the larval growth of the principal species to arrive at a corpse (Wolff et al, 2001;Perez et al, 2005;Martinez et al, 2007) in four different bioclimatic zones: L. eximia at 23.13°C and 25.30°C in Medellín and Gomez Plata, respectively; C. macellaria at 25.30°C and 30.74°C in Gomez Plata and Tintipán, respectively; C. albiceps at 25.30°C in Gomez Plata; C. megacephala at 23.13°C in Medellín and C. nigribasis at 10.62°C in Chingaza. L. eximia seems to be very sensitive to stress and in the present study this could have been caused by the lack of a successful migration event and posterior burial.…”

“…Martinez et al (2007) conducted a study in Paramo, Colombia, and they noted that the blowfly is observed during stages III and IV but not at the Skeletonization (V) stage. The rapid carcass weight loss is associated with the conversion of the carcass biomass to larval biomass; subsequently, larval insects leave the carcass during pupation.…”

Abstract. The knowledge of insect patterns visiting decomposing carcasses and the analysis of parameters related to their presence help determine the post-mortem interval (PMI). This information depends on regional studies because the diversity of insects and the environmental conditions interfere in this process. The aim of the study was to analyze the insect fauna that colonizes carcasses of pigs exposed in different stages of decomposition in the study area. The experiment was conducted in southern Brazil using three domestic pigs (Sus scrofa Linnaeus) that were killed on site. Adult insects associated with carcasses were sampled daily using an insect net, manual collection and pitfall traps. Statistical tests were performed to evaluate the diversity of insects. During the process of decomposition (14 days), Scarabaeidae (25%) and Calliphoridae (23%) species were the most abundant of all of the samples. The diversity of insects is distinguishable when all parameters are analyzed. The Black Putrefaction (IV) stage exhibited the highest diversity according to the applied methods. The succession pattern was established from the species dominance index: Fresh stage -Lucilia eximia Wiedemann (Diptera, Calliphoridae); Chromatic and Bloat -Chrysomya albiceps (Wiedemann) (Diptera, Calliphoridae); Black Putrefaction and Skeletonization -Aphodiinae sp. 1 (Coleoptera, Scarabaeidae).Keywords: Colonization; forensic entomology; postmortem interval; scavenger insects; Sus scrofa. Entomofauna Associada a Carcaças de Suínos Expostas no Sul do BrasilResumo. O conhecimento dos padrões de insetos que visitam carcaças em decomposição e a análise dos parâmetros relacionados a sua presença auxilia na determinação do intervalo post-mortem (IPM). Estas informações dependem de estudos regionais, pois a diversidade de insetos e as condições ambientais interferem neste contexto. O objetivo do estudo foi analisar a entomofauna que coloniza carcaças expostas em diferentes estágios de decomposição na área de estudo. O experimento foi conduzido no sul do Brasil utilizando três porcos domésticos (Sus scrofa Linnaeus), abatidos no local. Insetos adultos associados às carcaças foram amostrados diariamente com rede entomológica, coleta manual e armadilhas pitfall. Foram realizados testes estatísticos para avaliar a diversidade de insetos. Durante o processo de decomposição (14 dias), espécimes de Scarabaeidae (25%) e Calliphoridae (23%) foram os mais abundantes, considerando-se a totalidade das amostras. A diversidade de insetos é distinguível quando são analisados todos os parâmetros. A fase de Putrefação negra (IV) exibiu a maior diversidade de acordo com os métodos aplicados. O padrão de sucessão foi estabelecido a partir do índice de dominância das espécies: fase Fresca -Lucilia eximia Wiedemann (Diptera, Calliphoridae), fase Cromática e de Inchamento -Chrysomya albiceps (Wiedemann) (Diptera, Calliphoridae), e fase de Putrefação Negra e de Esqueletização -Aphodiinae sp. 1 (Coleoptera, Scarabaeidae).

“…In Colombia, records of this fly subfamily are scarce, with the little information being mostly the result of recent studies on forensic entomology (Wolff et al 2001, Pérez et al 2005, Martínez et al 2007, Buenaventura et al 2009, Barrios and Wolff 2011, Ramos and Wolff 2011, Ramírez-Mora et al 2012, Amat et al 2013, Yepes-Gaurisas et al 2013, Ramos-Pastrana et al 2014, Mello-Patiu 2016. The catalogue of Sarcophagidae from Colombia (Mello-Patiu 2016) listed 102 species in 26 genera and two subfamilies, of which 96 species belong to Sarcophaginae.…”

ABSTRACT. Sarcophaginae is the most diverse subfamily of Sarcophagidae with 51 genera and more than 1,800 species and it is widely distributed in the Neotropical Region. Sarcophaginae flies of forest, rural, and urban habitats of the seven departments comprising the Colombian Guajira biogeographic province were surveyed. Van Someren Rydon traps baited with fermented fruit, decomposing fish, and human feces were active for 72 hours with samples collected every 12 hours (day/night) between 2010 and 2014. A total of 14,223 sarcophagines (78% females and 22% males) were collected, which belong to 28 species of nine genera. Oxyvinia excisa (Lopes, 1950) is a new record for Colombia. The richest genera were Oxysarcodexia Townsend, 1917 and Peckia Robineau-Desvoidy, 1830, with eleven and nine species, respectively. Some of the species with the highest affinity to urban habitats were Oxysarcodexia bakeri (Aldrich, 1916), Oxysarcodexia aurata (Macquart, 1851), and Oxysarcodexia timida (Aldrich, 1916); to rural habitats were Oxysarcodexia diana (Lopes, 1933), Ravinia columbiana (Lopes, 1962), and Ravinia effrenata (Walker, 1861); and to forest habitats were Helicobia rapax (Walker, 1849), Oxysarcodexia avuncula (Lopes, 1933), and Oxysarcodexia major Lopes, 1946. We also discuss diet, habitat, and activity periods of the species. Species composition of Sarcophaginae in the Guajira province was very homogenous across the habitats, with the forest as the richest habitat. Scavenger habits of Sarcophaginae are confirmed, as well as their strong association with anthropic environments.
