Plodia interpunctella larvae were obtained from established laboratory cultures, field infestations, and outdoor containers simulating normal storage conditions. Supercooling points were measured by surface contact thermometry and recorded as the lowest temperature reached before crystallization. Plodia interpunctella is one of the most cold hardy stored product pests, overwintering as a mature larva in locations subject to great temperature fluctuations. Results and their potential use in non-chemical control will be discussed.
