In this article,the rationales of data analysis of group-reared life table and the methods of converting them into individually-reared life table were described.The daily record of group-reared life table is actually the matrix N of the age-stage,two-sex life table,while the record of daily total fecundity of all females is the matrix Ftotal.Based on the matrices of N and Ftotal,the age-stage survival rate matrix S,the fecundity matrix F and the population parameters can be calculated.Using Myzus persicae and Phthorimaea operculella as examples,we clarified the theoretical basis of group-reared life table,proved the parameters obtained from the group-reared life table to be reliable,and introduced a method to convert group-reared life table into individually-reared life table.We also compared the features of group-reared life table and individually-reared life table.The application of group rearing to study insect life tables can not only save a lot of labor,time and cost,but also can be used to design mass-rearing system for the production of natural enemies for biological control,insects as foods for birds and fishes,and edible insects for human.
