The author examined the systemic affiliation, morphology, occurrence and significance of the damage incurred in historical monuments by the death-watch beetle (Anobium punctatum De Geer). The article discusses the possibility of reducing local death-watch populations in wooden buildings by resorting to parasites and predatory insects, and describes the characteristic reactions of the deathwatch larvae to certain poisons contained in wood protection agents and physical factors used for combating the pest. Emphasis is placed on the absence of suitable research concerning pertinent wood protection agents, discernible during last decade.
