Abstract: The populations of Bemisia tabaci biotype Q can be divided into four stages including eggs, young nymphs, senile nymphs and adults according to the growth and development process, and the factors of each stage were divided independently. Based on the field surveys on natural populations and laboratory observation on experimental populations of Bemisia tabaci biotype Q, the natural population life table of Bemisia tabaci biotype Q in tobacco was investigated. The results showed that the trend index (I) of natural population of Bemisia tabaci biotype Q was 28.22, indicating that the population of next generation would be 28.22 times of the contemporary population, and the general survival rate was 11%.
