Insect fauna epiedaphic in areas of ecological restoration of the parque ecológico cantarrana (Bogota D.C.)

Se caracterizó de manera preliminar la diversidad de la entomofauna del Parque Ecológico Cantarrana con énfasis en los insectos caminadores del suelo y de la hojarasca. Para el muestreo del área se subdividió en tres zonas (Alta, Media, Baja), cada una con diferente estado de desarrollo de la vegetación, siendo principalmente arbórea o arbustiva. Para este fin se emplearon tres métodos de recolección de insectos: la captura directa diurna durante 3 horas; extracción a partir de 18 muestras de hojarasca empleando el embudo Berlesse y 30 trampas de caída por cada zona distribuidas en 3 transectos de 100 metros, para un total de 90 trampas. Se realizó un muestreo entre la tercera semana de Julio y el mes de Agosto en la época húmeda. Se recolectaron 1776 individuos representados en 9 ordenes, 44 familias y 53 morfoespecies. En la edafofauna encontrada predominaron las familias Staphylinidae (Coleoptera), Forficulidae (Dermaptera) y Formicidae (Hymenoptera), siendo organismos de hábitos saprófagos, fitófagos, depredadores y omnívoros. Por último, se encontró la diversidad general de la entomofauna muestreada no se diferenció significativamente entre las zonas comparadas, sin embargo, se observa una tendencia a mayor diversidad en la zona con predominio de vegetación de porte arbustivo.Insect fauna of the “Parque Ecológico Cantarrana”, with emphasis in soil and litter, was preliminarily characterized. Sampling are was subdivided in three zones (High, Medium, Low) each with different vegetation age and size mainly arboreal or shrubby. Three insect collecting methods were used: direct diurnal capture for 3 hours; extraction from 18 litter samples using Berlesse funnels and 30 pitfall traps per zone. Traps and sampling was conducted in three transects, of 100 meters each, which gave a total of 90 traps. Sampling was performed during the third week of July and the month of August during the wet season. A total of 1776 insects were collected, represented in 9 orders, 44 families and aprox. 53 morphospecies. Staphylinidae (Coleoptera), Forficulidae (Dermaptera) and Formicidae (Hymenoptera) families, predominated in the sampling, wich are organisms with saprophagous, phytophagous, predatory and omnivorous habits. Finally, it was established that the general diversity of the insect fauna sampled did not differed significantly among the sampled areas, however, there is a tendency towards greater diversity in the areas predominated by shrubby vegetation.Jardín Botánico Jose Celestino Muti
