摘要
通过在28℃恒温条件下的饲养观察,组建了竹织叶野螟实验种群的特定年龄生命表和生殖力表。结果表明:竹织叶野螟各虫态的存活率变幅在64%~96%,其中以卵期存活率最高,三龄幼虫存活率最低,且种群存活曲线呈PriceⅣ型分布;种群趋势指数为35.62,世代平均历期为53.926 d,内禀增长能力为0.062,周限增长率为1.064。
Based on the observation of the breeding of Algedonia coclesalis at a constant temperature of 28℃,the life table of this experimental population was constructed.The survival rate in each developmental period was from 64 % to 96%,of which the highest survival rate was at the egg phase and the lowest at the 3rd instar larva phase.The population survivorship curve fitted Price′s type Ⅳ,the population trend index(Ⅰ) was 35.62,the average generation period(T) was 53.926 days,and the innate capacity(rm) and finite rate(λ) of population increase were 0.062 and 1.064,respectively.
