Abejas silvestres como estrategia de monitoreo de restauración ecológica en tres veredas del corregimiento La Gallera (Tambo, Cauca), zona de amortiguación del Parque Nacional Natural Munchique (PNNM).

Abstract

Wild bees can be useful elements to monitor the state of ecosystems. This study contributes to the knowledge of these insects in the Department of Cauca and especially in the Corregimiento La Gallera. The composition of wild bees in the area was determined and how this can provide information in the PNNM management plans. Samplings were carried out in two different ecosystems in three districts, El Cóndor (forest and restoration plot of land), El Rosal and La Gallera (forest and forage banks). Four methods were used: entomological insect net, Malaise trap, Van Someren Rydon trap, and artificial baits distributed in two 200 m transects. 432 specimens were collected , grouped into 42 species and four families of bees: Apidae, Halictidae, Megachilidae and Colletidae. 34 species were collected in El Rosal, 18 species were collected in El Cóndor and 9 species were collected in La  Gallera.  Neocorynura and Augochloropsis, were the genus with a greater number of species. Colletidae family had a single representative belonging to the genus Chilicola Spinola which was collected in El Rosal. The greatest richness was registered in El Rosal (81%), followed by El Cóndor with 43% and finally La Gallera with 21%. The species Partamona sp.1, Trigona (Trigona) truculenta,  Parapartamona caliensis  and  Partamona  sp.2 were found in the three districts from which, the three first were the most abundant.
