Use of freeze disinfection for the control of the common furniture beetle Anobium punctatum
L Stengård Hansen
The common furniture beetle Anobium punctatum is an extremely widespread pest of wooden objects in Danish museums. In order to develop non-chemical methods of controlling the pests, experiments were conducted to elucidate the lower lethal temperature of Anobium punctatum. The egg stage was used for the experiments as it is considered the most temperature resistant stage. Groups of Anobium punctatum eggs were exposed to temperatures of -14, -18, -22, -26 and -30°C. Freezing durations were 8 hrs, 24 hrs and 48 hrs, respectively. Preliminary results of the experiments are presented.
