Abstract
Acclimation for a few days in cold resulted in a remarkable increase o f cold hardiness in an early spring active coccidophagous ladybird bee tle, Exochomus quadripustulatus (Linnaeus, 1758). The supercooling poi nt decreased from -9.1 degrees C in postdiapause, warm-acclimated adul ts to -17.2 degrees C in reacclimated individuals. Survival correspond ed to the supercooling point.
