Abstract: Abstract: The objective of this study was to control the damage on tobacco from Tribolium confusum Jacquelin du Val. The irradiation effects of 60Co γ-rays on the adults of Tribolium confusum Jacquelin du Val in tobacco were studied. The results showed that the adults of Tribolium confusum Jacquelin du Val irradiated by the doses over 100Gy could prevent offspring reproduce; larvaes could be found after 150 Gy irradiation for adults, but the larvaes couldn’t develop into adults; there were almost no feeding of adults after irradiation by the doses no less than 200Gy, and the adults completely died finally. So 200 Gy was the effective dosage of 60Co γ-rays for the control on the adults of Tribolium confusum Jacquelin du Val in tobacco.
