| Sumario: | The research provided information about the abundance and diversity of insects Scolytinae in primary and secondary formation within the protective Murocomba Forest enclosure belonging to Valencia canton province of Los Rios, the objective was to evaluate the differences in the diversity of insects Coleopteran: Curculionidae, Scolytinae formations in primary and secondary forest. A Journey was conducted within forest formations to proceed to the location of 20 traps (10 per forest formation) intercepting flight according to the methodology Jiri, considering the tree species where the trap was located, with a mixture of ethyl alcohol with antiseptic gel (Carbopol-Triet-Alcohol) 90% and 10% water with a volume of 100 ml per container. The collection of specimens was conducted during a period of 10 days with a total of 6 records for the identification laboratory used taxonomic keys described by Wood. A total of 18 species of insects were reordered Corthylus 1 Corthylus 2 and Xyleborus affinis which registered greater presence, Corthylus 1 presented greater abundance in the secondary forest, in primary forest 17 species were recorded being Corthylus 1 and Xyleborus affinis species greater presence and Corthylus 1 the most abundant were recorded. Diversity indices of Shannon and Simpson in secondary forest formation recorded greater diversity for traps located on the tree species T. cumingiana and T. micrantha while M. grandifolia species, P. xanthochyma for the formation of primary forest. Jaccard index revealed a value of 0.842 x 100% similarity, which describes a high percentage of insect species associated between the primary and secondary forest. The diversity of Scolytinae species formations between secondary and primary forest showed significant differences. The proposal of using scolytinae insects as bioindicators of anthropic disturbances exposes the tribe Premnobius cavipenis as the indicator insect with presence in the formation of disturbed forest. |
