Abstract
La familia Calliphoridae son los dípteros de importancia forense más abundantes junto con Sarcophagidae y Muscidae debido a que sus estadios inmaduros usan cadáveres humanos y de animales como fuente de sustento para su crecimiento, siendo los descomponedores de consideración (Horenstein et al, 2010). Se determinó la presencia de dípteros Calliphoridae necrófagos de interés forense colectados en dos zonas (Urbana y Rural) en la Provincia de Bellavista – San Martín. El proyecto se desarrolló durante los meses de enero a junio 2022, se realizaron dos colectas por mes, una en zona urbana y otra en zona rural. Los dípteros adultos se capturaron con el uso de una trampa Van Someren-Rydon modificada utilizando como atrayente biológico 250 gramos de vísceras de pollo y cabezas de pescado en estado activo de descomposición. En cada colecta se tomaron datos de temperatura y humedad relativa (promedio: 24.2°C y 80%). Se colectaron un total de 1,255 individuos correspondientes a las especies del orden Diptera: C. albiceps, C. megacephala, C. putoria, C. macellaria, L. eximia, L. cuprina y L. sericata. Siendo los primeros colonizadores en zona Urbana: C. albiceps a partir de febrero (34.96%), C. megacephala (57.89%) (más abundante), C. putoria (46.88%) y C. macellaria (14.29%), y en zona Rural: C. albiceps (12.5%), C. megacephala (57.89%), C. putoria (93.01%) (más abundante) y C. macellaria (14.42%). La fluctuación poblacional en dípteros Calliphoridae en zona Urbana se presentó para: C. albiceps (ausente en enero y marzo), L. cuprina (presente solo en enero) (10.53%), L. eximia (ausente en marzo) y L. sericata (ausente en enero, abril, mayo y junio); en zona Rural: L. cuprina (ausente en marzo), L. eximia (ausente en enero y marzo), L. sericata (ausente en febrero, abril, mayo y junio).
The Calliphoridae family are the most abundant diptera of forensic importance along with Sarcophagidae and Muscidae because their immature stages use human and animal corpses as a source of sustenance for their growth, being important decomposers (Horenstein et al, 2010). In this study, the presence of necrophagous Calliphoridae diptera of forensic interest collected in two areas (Urban and Rural) in the Province of Bellavista – San Martín was determined. The project was developed during the months of January to June 2022, two collections were carried out per month, one in an urban area and another in a rural area. Adult diptera were captured with the use of a modified Van Someren-Rydon trap using 250 grams of chicken viscera and fish heads in an active state of decomposition as a biological attractant. In each collection, temperature and relative humidity data were taken (average: 24.2°C and 80%). A total of 1,255 individuals were collected corresponding to the species of the order Diptera: C. albiceps, C. megacephala, C. putoria, C. macellaria, L. eximia, L. cuprina and L. sericata. Being the first colonizers in the Urban area: C. albiceps from February (34.96%), C. megacephala (57.89%) (most abundant), C. putoria (46.88%) and C. macellaria (14.29%), and in Rural zone: C. albiceps (12.5%), C. megacephala (57.89%), C. putoria (93.01%) (most abundant) and C. macellaria (14.42%). The population fluctuation in Calliphoridae diptera in the Urban area was presented for: C. albiceps (absent in January and March), L. cuprina (present only in January) (10.53%), L. eximia (absent in March) and L. sericata (absent in January, April, May and June); in Rural areas: L. cuprina (absent in March), L. eximia (absent in January and March), L. sericata (absent in February, April, May and June).
