RESUMO:

foresty restoration programs are of great importance for the recovery of degraded areas in caatinga. A possible way forward for the development of restoration techniques would be understand how the diversity of tree species and the composition of the different associations of these species would affect the success of the restoration. Restoration tecniques should also provide colonization of the degraded area by other trophic levels, such as insects. The insect community interferes with the performance of the plants, since the intensity of herbivory can consume the plant in its entirety. Thus, this work has the general objective of analyzing how restored plant communities influence the insect community in the initial stage of restoration. The study was conducted in the Açu National Forest (Açu / RN). The experiment was created in 2016 for the restoration of a caatinga area by planting 4,704 seedlings of 16 native tree species. Planted in 155 plots of 8 x 13 m and presenting five levels of diversity: 1 species, 2 species, 4 species, 8 species and 16 species, per plot. During the months of June and July, rainy session, of 2017, manual collections of the insects that were on the plants transplanted in the restoration project were carried out. To understand how the relationship between plant diversity and richness and abundance of insects works were performed factorial ANOVAs. We found that the diversity and abundance of insects are generally greater for species when they are in plots with low plant diversity (up to 4 plants). This corroborates with our hypothesis that in plots of greater diversity, plants have fewer insects and therefore have less damage due to herbivory. Being favorable to the restoration the implementation of a greater diversity of plants in its programs.
