Abstract: The active factor life tables of natural population of banana pseudostem weevil were built,and the controlling effect of active factors was evaluated by using exclusion index of population control (EIPC). The results showed that the population trend indices in growing and harvested banana trunks were 4.3481 and 3.6628,and the EIPCof predation and others were 1.9256 and 2.3577,respectively. The EIPCof natural death were 1.3607 and 1.3554,and that of parasitism and disease in growing and harvested banana trunks were 1.1988 and 1.1668, respectively. The factor of predation and others was important.
