Durabilidade natural do estipe de pupunha (Bactris gasipaes Kunth, Arecaceae) II: insetos

The durability of the stipe of Bactris gasipaes Kunth (Peach palm) when under attack by xylophage insects, is evaluated in the present paper, through forest and urban environment field tests. Five palms with spines and five without spines from the Tabatinga population (Putumayo landrace) were used i...

Five palms with spines and five without spines from the Tabatinga population (Putumayo landrace) were used in the experiment. Disks approximately 30 cm thick were taken from the butt, middle and top portions of each palm and distributed at random in a forest area near the INPA Peach Palm Germoplasm Bane (2º38'S 60º03'W). The time of permanence of the samples was 18 months, and in this period the disks were checked every three months to evaluate the degree of deterioration and collection of insects. In the urban condition, the same procedure was adopted, however each disk was halved to remove the centre and each half was distributed at random, one in a concave and the other in a convex position, on a wooden framework situated in the INPA's campus, Manaus, and checked bimonthly for one year. The results in the forest condition indicated that most of the disks were deteriorated by termites, and useful life of the butt portions varied around 18 months, the middle and the top around 15. The main species of termites were: Heterotermes tenuis (Hagen) (Rhinotermitidae) attacked the butt, middle and the top parts; Nasutitermes similis Emerson (Termitidae) that infested the area of the base and of the middle; Anoplotermes sp. (Termitidae) and Nasutitermes tatarandae (Holmgren) (Termitidae) attacked the medium part of the stipe. In the urban condition, the beetle Dinoderus bifoveolatus Wollston (Bostrichidae), was the most responsible for the deterioration of the samples, followed by the termite N. similis.", 'en Neste trabalho estão apresentados os resultados da durabilidade natural do estipe (madeira) de Bactris gasipaes Kunth (pupunha), quando submetido ao ataque de insetos xilófagos, em ensaios em ambiente florestal e urbano. Foram utilizados dez palmeiras, cinco com espinhos e cinco sem espinhos, de plantios da Fazenda Experimental da Universidade Federal do Amazonas, localizada no km 40 da rodovia Manaus-Boa Vista (BR 174). De cada uma das palmeiras foram cortados três discos de aproximadamente 30 cm de espessura, retirados da base, do meio e do topo. No ambiente florestal, os discos foram distribuídos aleatoriamente, em área próxima ao plantio, no espaçamento de 0,5m, permanecendo durante 18 meses, período no qual foram efetuadas seis inspeções trimestrais para avaliar o grau de deterioração e coleta de insetos. Para o ensaio em condição urbana, os discos foram secionados axialmente para a retirada da medula e distribuídos aleatoriamente, nas posições côncava e convexa, sobre uma estrutura de madeira, localizada no Campus do INPA em Manaus, e inspecionados bimestralmente por um ano. Os resultados do ensaio no ambiente florestal indicaram que a maioria dos discos foi deteriorada por térmitas e a vida útil da base foi em torno de 18 meses, a do meio e do topo em torno de 15. As principais espécies de cupins foramHeterotermes tenuis (Hagen) (Rhinotermitidae) responsável pela deterioração da parte basal, mediana e o topo; Nasutitermes similis Emerson (Termitidae) que infestou a região da base e do meio; Anoplotermes sp.(Termitidae) e Nasutitermes tatarandae (Holmgren) (Termitidae) responsáveis pela infestação da parte mediana do estipe. No ambiente urbano, o principal responsável pela deterioração das amostras foi o besouro Dinoderus bifoveolatus Wollston (Bostrichidae), e em seguida, o térmita N. similis. 2020-04-24T15:15:24Z 2020-04-24T15:15:24Z 2004 Artigo https://repositorio.inpa.gov.br/handle/1/13163 10.1590/S0044-59672004000300011 pt_BR Volume 34, Número 3, Pags. 459-465 Attribution-NonCommercial-NoDerivs 3.0 Brazil http://creativecommons.org/licenses/by-nc-nd/3.0/br/ application/pdf Acta Amazonica
