Abstract: Studies were undertaken to establish the effects of low temperatures on the growth of cigarette beetle.The results showed that the larvae had the highest tolerance to low temperature,followed by adults and eggs. At the temperature of－20℃,the death rate of cigarette beetle of all life stages were 100%. At the temperature of－10℃,the eggs and adults were died by treated 1 h,and the larvae need 72 h. The eggs of cigarette beetle can not hatched by treated 72 h at 5℃. At the temperature of 5℃,the nymphosis of larvae and the eclosion of adults were affected,but can not be killed. At all of the temperatures tested,the final eclosion rate and the amount of spawned egg were all zero. The highest eclosion rate is 41. 67% at 5℃and 0℃. In contrast,the final eclosion rate of larvae was 77% and the final hatching rate of egg was 52%.
