Seeds samples used to make biojewellery was collected and take to Forest Entomology Laboratory at Rural University of Rio de Janeiro, where the damages were observed and the family of the insects were identified. The families were: Scolitydae and Anobiidae. It is possible to decrease the insect damage with appropriate seed store or make use of damage seeds, after heating with the objective of eliminate the insects. To know the viability of seed collection, Leguminosae seeds, used in urban forestry, Albizzia lebbeck (L) Bentham, Cassia fistula L., was collected in Serop?dica (RJ), one sample with 500 fruits of Albizzia lebbeck (L.) Bentham, after processing, were found: 23,38% of the seeds were damaged by insects, 60,41% of the seeds were empty and 16,21% were not damaged by insects. The sample with 100 fruits of Cassia fistula L. was collected in Itagua? (RJ) and 83,35% of the seeds were damaged by insects, 10,96% of the seeds were empty and 5,69% were not damaged by insects. The seeds of both species are damaged by Bruchidae. To check the damage caused by insects Anobiidae in the storage, they were placed in contact with healthy seeds and seeds damaged by insects of Albizzia lebbeck (L.) Bentham and seeds of healthy and mechanically damaged of Adenanthera pavonina L. Twenty adult insects were used and 10 seeds for each situation, using five repetitions. After 60 days there was Anobiidae damage just in damaged seeds / O objetivo desse trabalho foi buscar maiores informa??es sobre danos de insetos em sementes de esp?cies florestais utilizadas para a confec??o de bioj?ias. Amostras de sementes utilizadas para confec??o de bioj?ias de um projeto foram coletadas e levadas ao laborat?rio de Entomologia Florestal da Universidade Federal Rural do Rio de Janeiro, onde se realizou a an?lise dos danos e a identifica??o da fam?lia dos insetos. Foram encontradas duas fam?lias causando danos nas sementes: Scolytidae e Anobiidae. Visando o aproveitamento das sementes atacadas, as mesmas foram tratadas e posteriormente utilizadas para a confec??o de bioj?ias e artesanato. O estudo mostrou que ? poss?vel aumentar o rendimento das sementes, seja com o armazenamento adequado ou at? mesmo aproveitando as sementes atacadas, utilizando o aquecimento para eliminar os insetos. Para conhecer a viabilidade da coleta de leguminosas ex?ticas utilizadas na arboriza??o, Albizzia lebbeck (L) Bentham e Cassia fistula L., coletou-se em Serop?dica (RJ) uma amostra de 500 frutos de Albizzia lebbeck (L.) Bentham, ap?s beneficiamento foram registradas 23,38% de sementes danificadas por insetos, 60,41% de sementes chochas e 16,21% de sementes sadias. A amostra de 100 frutos de Cassia fistula L. foi coletada em Itagua? (RJ) e foram registradas 83,35% de sementes danificadas por insetos, 10,96% de sementes chochas e 5,69% de sementes sadias. As sementes de ambas as esp?cies s?o danificadas por insetos da fam?lia Bruchidae. Para verificar os danos causados por insetos da fam?lia Anobiidae no armazenamento, os mesmos foram colocados em contato com sementes sadias e danificadas por insetos de Albizzia lebbeck (L.) Bentham e sementes sadias e danificadas mecanicamente de Adenanthera pavonina L. Foram utilizados vinte insetos adultos e 10 sementes para cada situa??o, sendo cinco repeti??es. Depois de 60 dias verificou-se dano de Anobiidae somente nas sementes danificadas.
