The thermal death point of Callosobruchus maculatus Fabricius

ILOBA, B:N. and OSUJI, F.N.C.

ABSTRACT: A thermal death point of 51.5°C for 15 minutes exposure and 47.5°C for 4 hours exposure was determined for Callosobruchus maculatus F. Weight
loss was lower at higher humidities. Death after 12 hours exposure at 46°C was due to both high temperature and the loss of moisture by evaporation, and is therefore not regarded as a true thermal death point.
