摘要/Abstract

摘要： 通过调查研究,组建了以作用因子为组分的春季香蕉假茎象甲(Odoiporuslongicollis Oliver)自然种群生命表,在此基础上运用排除作用控制指数法分析了各种因子对假茎象甲自然种群的作用.结果表明,春季假茎象甲自然种群趋势指数成长蕉株上平均为4.3481,留头蕉茎上平均为3.6628.捕食及其它因子对该虫种群控制作用最大,排除作用控制指数成长蕉株为1.9256,留头蕉茎上为2.3577;自然死亡作用次之,成长蕉株为1.3607,留头蕉茎上为1.3554;寄生或疾病因子作用最小,成长蕉株为1.1988,留头蕉茎上为1.1668.捕食及其他是该虫种群增长的重要控制因子.

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.
