Summary

Larvae of the pyralid Ephestia elutella, a pest of stored products, were exposed to low temperatures from 5 to -10 deg C after different periods of acclimation. Accelerating the rate of temperature fall during acclimation increased the effectiveness of low temperatures in achieving kill. A 12-week exposure to a temperature cycling between 0 and -5 deg C caused little mortality. The survivors of low-temperature exposure emerged faster and with increased synchrony compared with those in control batches. To achieve control in practice, temperatures need to be reduced to well below -5 deg C for several weeks and to avoid insect acclimation, the fall needs to be rapid.
