N2  - K hapra beetle, Trogoderma granarium (Everts) (Coleoptera, Dermestidae) is qne of primary insects on stored grains. To control this pest with non-chemical methods, all stages (eggs, larvae, pupae and adults) of the pest were exposed to low and high temperature for different periods. Results revealed that mortality of all stages of T. granarium reached 100% after 7 and 5 days freezing at -10 and -15 °C, respectively. Eggs were more sensitive to low temperature than the other stages. On the other hand, high temperatures of 50 and 60 °C caused 100% mortality for all stages of the same pest after 6 hours of exposure. The increase of high temperature to 70 °C, the decrease of exposure period to 4 hours. Both low and high temperatures significantly affected germination and chlorophyll contents of wheat grains
