The range of five examined temperatures ( 15 to 35°C) had a remarkably stronger effect on all examined parameters than applied range of two relative humidities (75%; 85 or 95%). The highest intrinsic rate of natural increase (rm) and the highest finite rate of increase (lambda) were recorded when temperatures of 25 and 30'C were used. The generation time (T) ranged from approximately 10 weeks at 30"C and 75 or 85% RH to approximately 22 weeks when l 5°C was used. At 35°C there were no survivors of any immature stages of S. granarius regardless of relative humidity, so population parameters could not be counted. A brief narrative is presented on the potential of these environmental variables for control applications.}, type={Article}, title={Population parameters of Sitophilus granarius (L.)
