Diversidad de escolítidos (Coleoptera: Curculionidae: Scolytinae: Xyleborini) en bosque natural y en plantaciones de balsa (Ochroma pyramidale).

The present research project was carried out in three Yakusinchi forest locations located in the La Mana canton, EET Pichilingue located in the Mocache canton and the raft plantation located in the Vergel area of the Valencia canton. The objectives of the research were to identify the species of Escolítidos and to compare the diversity of Escolítidos in primary forest, secondary and a plantation of raft. 30 flight intersection traps were installed at a height of 1.30 m, traps were primed with ethyl alcohol (90%) and hand disinfecting gel (10%). The collection was performed every 15 days. A total of 18327 insects were collected, corresponding to 7258 individuals in the Yakusinchi primary forest, 5815 individuals in TSE Pichilingue secondary forest and 5254 individuals in the balsa plantation. The total number of individuals is grouped into 18 genera and 84 species, being the most abundant genera Xyleborus, Hypothenemus, Xylosandrus, Corthylus, and the most abundant species Xyleborus 02, Xyleborus affinis, Xylosandrus morigerus, Hypothenemus 19, Xyleborus volvulus, Hypothenemus 18, Corthylus 01. In the primary forest, the Shannon and Simpson index was 2.28 and 0.843 respectively, in the TSE secondary forest Pichilingue was 1.82 and 0.755 respectively, while in the balsa plantation it was 2.51 and 0.847 respectively, indicating that there is diversity in the three ecosystems. The richness index in the Yakusinchi primary forest, secondary to the Pichilingue TSE and the balsa plantation were 6.749, 5.768 and 7.004 respectively, indicating that the three ecosystems studied present a high number of pupils.
