This study aimed to verify the occurrence of insects in experimental reforestation with Schizolobium parahyba var. amazonicum (Fabaceae) known as paricá, Racosperma mangium (Fabaceae) known as acacia and Tectona grandis (Lamiaceae) known as teca in the region of Pau d'Arco, Pará State, Brazil associating the seasonal and ontogenetic effects in plantations. The study was conducted from May 2006 to June 2007 and consisted of monthly surveys of insects associated with plantations aging 3 to 16 months. There was a positive association between the occurrence of insects and their injuries with seasonality and plant development. At least one population peak of defoliators, sucking and / or pollinators were observed in three tree species. Cluster analysis confirmed the association between the occurrence of insects, rainy season and plant age, especially (a) lepidopteran in T. grandis, (b) defoliators beetles in S. parahyba, (c) acridids and lepidopteran in R. mangium (d) cicadellids in S. parahyba and T. grandis, and (e) apids in R. mangium.
