Abstract

Six weeks of continuous submersion in water of spruce bolts containing larvae and young adults of the spruce beetle resulted in complete mortality. We estimated that 22 days of continuous submersion would be required to kill 50% of the brood. Brood development ceased in the submerged bolts even though water temperature, which increased from 13.3°C to 17.8°C during the experiments, was well above the larval development threshold (6.1°C).
