摘　　要：荔枝蒂蛀虫(Conopomorpha sinensis Bradley)是影响荔枝生产及出口的重要害虫。由于其具有钻蛀为害的习性,其生态学研究薄弱。以荔枝果核、龙眼果核为饲料,在室内成功饲养了连续3个世代的荔枝蒂蛀虫。并编制了荔枝蒂蛀虫实验种群的特定时间生命表和特定年龄生命表。特定时间生命表参数为:第一世代R0(I)=2.0503,rm=0.0230;第二世代R0(I)=7.5067,rm=0.0538;第三世代R0(I)=0.3104,rm=0.0321。特定年龄生命表参数为:第一世代R0(I)=2.0594,rm=0.0217;第二世代R0(I)=7.5261,rm=0.0559;第三世代R0(I)=0.3114,rm=0.0333。研究了两类生命表参数之间的关系,并进行了相应的换算论证。通过R0≈I的关系,在本例中,两种生命表之间的参数是可以进行换算的。生殖力表不同于特定时间生命表,它丢失了幼期累计存活率而使R0失真。Litchi fruit borer （Conopomorpha sinensis Bradley） is an important pest which affects the litchi fruit production and the exportation. Because it has the damaging habit of drilling. Its ecological research is weak. With the kernel of litchi and longan as a food, litchi fruit borer has been reared continuously for three generations successfully in the room. Furthermore, the experiment population＇s time-specific life table as well as the age-specific life table of the litchi fruit borer has been established. The time-specific life table parameter is： Ro （I） = 2. 0503, rm = 0. 0230 for first generation; R0 （I） = 7. 5067, r = 0. 0538 for second generation; R0 （I） = 0.3104, r = 0. 0321 for third generation. The age-specific life table parameter is ： Ro （I） = 2. 0594, r = 0. 0217 for first generation ; R0 （I） = 7. 5621, r = 0. 0559 for second generation ; R0 （I） = 0.3114, r = 0. 0333 foe third generation. The relations between two kinds of life table parameter have been studied,and the corresponding conversion proof has been carried on. In this case, the conversion of parameters between two kinds of life tables may be carried on through the R0 ≈ I relations. The fecundity table is different with the time-specific life table, R0. is distorted because of the loss of the larval accumulative survival rate.
