[...]the survival status of L. serricorne in tobacco leaf threshing and redrying process under diferent conditions of temperature, humidity and duration had not been studied, so experiments were carried out to provide data suppor for the pre- vention and control of L. serricorne in tobacco leaf threshing and redrying workshop. 2 Materials and methods 2.1 Pest monitoring 2.1.1 Time. According to the biological characteristics studied by Wang et al. According to the leaf tobacco-threshing and redrying-technical specification in Tobacco Industry Standard of the People's Republic of China % YC/T 146-2010 & , the conditions of humidity 70% and 90% were simulated by artificial climate box, and the humidity of 0 was simulated by electric heating blast drying box. After the test, they were put back to the feeding conditions to continue feeding, and the number of deaths was checked after 48 h. 2.3 Data analysis Mortality rate % % & = % Number of dead insects/Number of test insects & X 100; Corrected mortality rate % % & = % Mortality rate of treatment group - Mortality rate of control group & / % 1 - Mortality rate of control group & X 100.
