RESUMO:

The largest coconut producers are in Southeast Asia, Brazil ranks fourth in the world, holding 15.3% of all world production. This entire cocoa production chain is directly affected by insects, being they decomposers, pests and natural enemies. Therefore, it is important to know the entomofauna of the place, to know if there is a balance between these groups of insects. The objective of this work is to know and compare the insect biodiversity of the general entomofauna and coleopterofauna, associated to the commercial coconut plantation in the northeast of Paraense (eastern Amazonia) in different seasons, environments and planting ages. The experiment was carried out in the municipality of Santa Isabel-Pará, with pitfall traps, in a commercial coconut plantation, for the installation, seven plots of different planting ages were used (being two of 2011, three of 2012, one from 2013 and one from 2014) and an area of riparian forest. There are eight areas monitored in each period (dry and rainy), with 40 traps each, totaling 640 in total. A multivariate classification using cluster analysis was conducted to measure the degree of affinity between the effects of collection area and also on insects collected. To measure the similarity between insects, the similarity of the Euclidean distance index was used to measure the abundance of the areas. A qualitative similarity method (Jaccard index) and quantitative similarity were used to measure dominance (BrayCurtis index ). Diversity analyzes were used in order to justify the similarities of cluster clusters, such as the Shannon index (H ') (Diversity), Simpson index (D) (dominance) and Pielou index (J') ( equitability). A total of 252,313 individuals were found, with 118 different families, divided into 10 orders. In both the dry and rainy periods, there was a dominance of formicidae, especially in the dry period. The other most frequent families in the 8 areas were Drosophilidae, Staphylinidae, Bostrichidae, Phoridae, Nitidulidae, Scolytidae Tenebrionidae, Scarabaeidae, Ceratopogomidae, Platyogastridae and Gryllidae. The riparian forest was the one with the greatest diversity, along with it, in the analysis of similarity is the A1 and A4 in the dry period and A3 and A5 in the rainy season, being these areas of plantations with greater diversity. A6 x A7 were to the areas that had greater similarity to have greater dominance of families, less equitability and less abundance, being more propitious to agricultural pests. The most abundant insects were the formicides, Drosophilideae, Brostechidae, Escolytidae and Staphylinidae; The riparian forest has a greater diversity and a smaller species dominance, when compared to the planted areas; The most diversified planting areas were A1 and A4 in the dry period and A3 and A5 in the rainy season; Older plantings are more diversified; The most pest-prone areas were A6 and A7; Seasonality influenced the flow of insects, with a larger number of specimens due to smaller amount of family in the dry period, less quantity of specimens by a larger amount of family in the rainy season.
