L. S. S.  aDiversity of hemipterans in Eucalyptus spp. plantations in Southeastern Pará, Eastern Amazon, Brazil.h[electronic resource]  c2025  aBrazil has 10.2 million hectares of reforestation, which account for 81% of the timber produced in the country. The order Hemiptera contains the main phytophagous species. The study of population surveys allows the analysis of faunal composition, resource availability, as well as potential pests in future plantations, contributing to sustainable pest management. The objective of this study was to evaluate the diversity of insects of the order Hemiptera in Eucalyptus spp. plantations in southeastern Pará, Eastern Amazon. Yellow adhesive traps were used to collect entomofauna, with 12 collections in total, (6) during the dry season and (6) during the rainy season. A total of 28 traps were installed in areas with clones of Eucalyptus urophylla, Eucalyptus grandis and Eucalyptus urograndis, in three municipalities in Pará. The insects collected were analyzed through the faunal indices of abundance,constancy, dominance and frequency, and diversity of Shanon and Pielou. Principal component analysis (PCA) revealed the families that most infuenced the diferent climatic seasons and in the diferent clones of Eucalyptus spp. A total of 18.320 individuals were collected, distributed in 24 families. The greatest abundance was observed in the dry season, infuencing the seasonality of the families that presented the highest faunal indices. Cicadellidae presented high indices in the three clones, highlighting the clone E. urograndis with the greatest diversity of insects and richness of families, during the dry season, which demonstrates the strong preference of the families for the season and for this species, and indicates a great risk of becoming a potential pest in future commercial plantations, monitoring and preventive actions are recommended to mitigate the impact of these species  aEucalyptus  aForest plantations  aInsect surveys  aEucalipto  aFloresta  aHemíptera  aInseto fitófago  aPhytophagous species  aSazonalidade1 aMACHADO, H.
