Abstract

Different methodologies are usually employed to evaluate Teredinidae wood-boring activity. Many authors using panels made of solid wood, estimated density by counting Teredinidae punctures on the wood surface or using x-ray techniques. However this technique does not allow the identification of species. A second approach, employing a collecting device made of sheets of wood, can be more effective for quantitative and qualitative analyses. The present paper compares density, species composition and diversity when using both solid and sheet panels. In addition different methods of estimating density were analysed. The results show that the evaluation of Teredinidae activity can change according to the methodology employed.
