Abstract:
The effect of exposure to 0, -5, -10 and -18 °C was investigated on all developmental stages of the stored product insects Tribolium castaneum (Herbst), Oryzaephilus surinamenisis (L.), and Ephestia cautella (Walker). For all three species the estimated time to produce 99% kill of the least sensitive stage of the least sensitive species ranged from 625 h for pupae of E. cautella at 0 °C, 55 h for pupae of E. cautella at -5 °C, 6.1 h for eggs of E. cautella at -10 °C, to 2.6 h for eggs of E. cautella at -18 °C. Interspecific comparisons of mortalities were made at the LT50 level, due to the wide confidence limits at high mortalities especially at the lower temperatures. For T. castaneum the adult was least sensitive at 0 and -5 °C and the pupa at -10 and -18 °C. For E. cautella the least sensitive stage at 0 and -5 °C was the pupa, and at -10 and -18 °C the egg. For O. surinamensis the least sensitive stage at 0 °C was the larva, at -5 and -18 °C the adult, and at -10 °C the pupa. © 1995.
