Abstract: The litchi fruit borer Conopomorpha sinensis Bradley is one of most serious pests in litchi orchard. The life tables of the litchi fruit borer population feeding on litchi variety Feizixiao were constructed according to the effects of the active factors in different development stages of the litchi fruit borer in this paper. The results showed that the fecundity of the litchi fruit borer feeding on litchi fruit were 160.3 eggs/female obviously higher than 99.6 eggs/female feeding on young shoots. The survival rate of litchi fruit borer feeding on litchi young shoots were 96.4%, while the survival rate was 90.7% for the borer feeding on litchi fruits. The life tables of litchi fruit borer feeding on litchi shoots and fruits in liboratory were constructed according to the effect of the active factors at different development stages of the litchi fruit borer. The trend indices of population of litchi fruit borer were 43.68 and 25.12 respectively at feeding periods of fruits and shoots.
