Abstract:The stored product insects Sitophilus granarius (L.) and Tenebroides mauritanicus (L.) survived temperatures down to 0°C for 40 days or more and continued to develop and reproduce when the temperature was brought up to 25°C. The tolerance of the insects to methyl bromide increased 25- to 35-fold when the temperature dropped from 25° to −6.7°C, so that a concentration of more than 500 mg/liter was required for complete control of the most tolerant species, T. mauritanicus. Insects preconditioned at a low temperature and treated at a higher temperature showed similar tolerance to methyl bromide as those preconditioned at the higher temperature. Both uptake of fumigant and respiration of the insects declined steadily as the temperature dropped from 25° to 0°C.
