Duration of Life-Cycle of the Death-Watch Beetle

  title={Duration of Life-Cycle of the Death-Watch Beetle},
  author={Ronald C. Fisher},
So far as published accounts record, the death-watch beetle (Xestobium rufovillosum, De G.) has never been bred in the laboratory and no study has, therefore, been possible of the factors affecting its development and the duration of its life-cycle. In discussing the treatment of timber roofs attacked by Xestobium, Lefroy1 summarised in 1924 the knowledge of the biology of the insect up to that time and pointed out how little was known of its life-histo and habits. 

Host selection behaviour of deathwatch beetle, Xestobium rufovillosum: Oviposition preference choice assays testing old vs new oak timber, Quercus sp.

Adult female deathwatch beetles were offered two dendrochronologically dated wood blocks from oak timber and showed a clear preference for ovipositing on old wood dating from the 13th to 19th centuries rather than new wood from the 20th century.

Behavioral Responses of Adult Deathwatch Beetles, Xestobium rufovillosum de Geer (Coleoptera: Anobiidae), to Light and Dark

Video tracking equipment was used to quantify the behavior of adult deathwatch beetles, Xestobium rufovillosum in a light/dark choice chamber, and results show that both male and female insects 1–12 days old prefer the light zone.
