Resumen
The high Andean forest in Colombia is between 2,800 and 3,200 meters high and is distinguished by its wide biological diversity. However, this ecosystem has been affected by anthropic activities such as grazing and agriculture that have drastically reduced its area in the country. In the Forest Park Embalse del Neusa you can see an example of this ecosystem and the disturbances it has suffered. The Pontificia Universidad Javeriana has developed an ecological restoration project implementing restoration strategies such as nucleation. The present work intends to estimate the structure of the entomofauna present in the vegetation nuclei of the Laureles sector. The sampling was carried out in the month of September 2017, using an entomological network for 15 minutes on the vegetation of 6 Controls and 6 Nuclei chosen at random. Indices of Simpson Dominance, Shannon-Wiener equity, Pilou equitability, principal component and multiple correspondence analysis, and a Bray-Curtis similarity test were performed. 32,988 insects were collected, being Chironomidaesp1 the most abundant morphotype in nuclei and Cicadellidaesp1 in controls. The nuclei presented 110 morphotypes and the controls 101. The dominance was low in controls and nuclei, the equity was medium as well as the equitability in both zones. Aphissp, Acrididaesp1 and Cicadellidaesp1 were associated to controls and Chironomidaesp1 to nuclei. The outer zones of nuclei present a greater association of morphotypes. The outer zone of nucleus 3 and 6 presented the greater similarity with 79.16%. The insects collected were classified into trophic guilds.
