An overview of the biology of the wharf borer beetle (Nacerdes melanura L., Oedemeridae) a pest of wood in marine structures

Abstract

The UK distribution of N. melanura is reported, based on records from museum collections, government laboratories and a field survey of wooden marine structures and driftwood along the English and Welsh coastlines. The global distribution is also reported, based on a questionnaire survey. The life cycle of the wharf borer under different environmental conditions is described and the environmental conditions over the adult emergence period presented. The cellulase complex, xylanase and a range of dissacharases were present in the larval digestive tract when tunnelling archaeological oak.
