In order to monitor the temperature change inside and outside No.1 storehouse of tobacco raw materials in Yan'an City,Shaanxi Province,and to explore the relationship between it and the mortality of tobacco beetle larvae.In this experiment,tobacco beetle larvae were exposed to different low temperature environments in winter,and their survival rate,fecundity and behavior changes were observed by different treatment time.The experimental results showed that the survival rate of tobacco beetle outdoors was 0 when the temperature entered the range of-20～-10℃for more than 14 hours,and the survival rate of tobacco beetle larvae was 0 when the temperature entered the range of-10～0℃for more than 54 hours.The survival rate of tobacco beetle larvae was as high as 75%when the temperature entered the range of 0～4℃for more than 360 hours.In addition,low temperature also affected the fecundity and behavior ability of tobacco beetle.
