Utilização de insetos deterioradores da madeira na avaliação da restauração florestal em Mata Atlântica

Abstract

The insects have been used to establish the anthropic interference in diverse ecosystems. Timber deteriorative insects can be used as bioindicators of environmental quality fragments and reforestation. This study aimed to synthesize ecological assessment of ecological restoration carried out in the Atlantic Forest in the basin of Guapiaçu River in Cachoeiras de Macacu, RJ. Six sampling points were placed along the Guapiaçu River basin, five points inferred in reforestation carried out in the basin and a point in control area, upstream of the Guapiaçu River. For timber deteriorative Coleoptera capture, samples were taken every 15 days, with the trap Carvalho-47 model. The trap was introduced into the forests to 1.5 meters away from the road about 70 meters, 3 traps were used per study area, totaling 18 traps. To capture Isoptera, quantitative samples were marked into six transects, one at each sample point, distant from one another at least 100 m. The collection period was started in January 2013, ending in December 2015. Through qualitative and quantitative data, there was a greater density of Coleoptera, Scolytinae during periods of high temperature and humidity and in areas with high density of pioneer species used in forest restoration. For Isoptera, areas with high density of pioneers showed the largest gradient Timber deteriorative insects. After the monitoring, an evaluation model was proposed for timber deteriorative Coleoptera focusing on FO%, entitled TTWBEM (Taxa Table of Woodboring Beetles for the Environmental Monitoring) and Isoptera, a monitoring model was proposed based on the food niche .
