To determine the effect of the factors of the environment (temperature, relative humidity, and food) on the population growth of Tribolium brevicornis, different levels of temperatures from 17.5°C - 37.5°C were used. Effect of these IeveIs of temperatures was tested upon both pre-embryonic and post-embryonic development. No hatching occurred at 17.5°C, but the threshold temperature (the minimum temperature for the development) was just before 17.5°C. The optimum temperature for the embryonic development was found to be between 32.5°C - 35°C.
