dc.description.abstractForensic entomology, commonly used worldwide, is not used in Puerto Rico due to the lack of a database of forensically important insects. This study presents the temporal, quantitative and qualitative distribution of insects asociated in the decomposition of Sus domesticus exposed to sun, partial shadow, and total shadow in Mayagüez, Puerto Rico. Samples of immature and adult insects were collected from three pigs weighing approximately 23 kg. The data were taken simultaneously with corpse and maggot mass temperature, relative humidity, and ambient temperature. The decomposition stages observed were fresh, bloated, active, advanced, and dry remains. A total of 6845 insects from 73 species, 10 orders and 39 families were collected. The environmental conditions of each study site influenced the duration of the decomposition stages and the associated insect community. The forensically important insects were Chrysomya rufifacies and Cochliomyia macellaria (Diptera: Calliphoridae), Hydrotaea aenescens and Fannia pusio (Diptera: Muscidae and Fannidae), and Dermestes maculatus, Necrobia rufipes, and Philontus hepaticus (Coleoptera: Dermestidae, Cleridae and Staphylinidae, respectively). The ants Solenopsis geminata, Odontomachus haematoda and Camponotus sexguttatus were the main predators reducing the populations of eggs and larvae. Results showed a pattern of insect succession, demonstrating that this tool can be used to resolve forensic cases in Puerto Rico.en_US
dc.description.abstractLa entomología forense se utiliza a nivel mundial, pero no en Puerto Rico debido a la falta de una base de datos de insectos de importancia forense. Este estudio presenta la distribución temporal, cuantitativa y cualitativa de insectos que participaron en la descomposición del cerdo Sus domesticus bajo condiciones de sol, sombra parcial y sombra total en Mayagüez Puerto Rico. Se tomaron muestras de insectos (adultos e inmaduros) en tres cerdos de unos 23 kg de peso, junto con datos de humedad relativa, temperatura ambiental, corporal y de las masas larvales. Se presentaron los estados de descomposición fresco, hinchado, activo, activo avanzado y esqueletal. Se colectaron 6845 especimenes adultos de 73 especies, 39 familias y 10 órdenes. El medio ambiente de cada condición de exposición condicionó la duración de los estados de descomposición y la entomofauna asociada a los mismos. Los insectos de importancia forense fueron Chrysomya rufifacies y Cochliomyia macellaria (Diptera: Calliphoridae), Hydrotaea aenescens y Fannia pusio (Diptera: Muscidae y Fannidae), Dermestes maculatus, Necrobia rufipes, Philontus hepaticus (Coleoptera: Dermestidae, Cleridae y Staphylinidae). Las hormigas Solenopsis geminata, Odontomachus haematoda y Camponotus sexguttatus fueron los depredadores principales que redujeron la población de huevos y larvas. Se obtuvo un patrón en la sucesión de la entomofauna que demuestra que esta herramienta puede utilizarse para la resolución de casos forenses en Puerto Rico.en_US
