摘要/Abstract

摘要： 通过在(26±1)℃恒温条件下的饲养观察，组建了广聚萤叶甲实验种群的特定年龄生命表和生殖力表。结果表明：广聚萤叶甲卵、幼虫、蛹和产卵前期的历期分别为7.51、12.14、7.67和4.75 d；各虫态的存活率变幅在77％~94％，其中以卵期存活率最高，3龄幼虫存活率最低，且种群存活曲线呈DeeveyⅡ型分布；单雌平均产卵量为193.8粒；种群趋势指数为36.95，世代平均历期为31.37 d，内禀增长能力为0.095，周限增长率为1.10。

Abstract: Through the breeding and observation at constant temperature (26±1) ℃, the life table of laboratory population of Ophraella communa was constructed. The development duration of egg, larva, pupa, and preoviposition of O. communa was 7.51, 12.14, 7.67, and 4.75 days, respectively. The survival rate in each developmental period was from 77% to 94%, being the highest for egg, and the lowest for the 3rd instar larva. The population survivorship curve fitted Deevey’s type Ⅱ, the number of eggs laid per female was 193.8, the population trend index (I value) was 36.95, the average generation period (T) was 31.37 days, and the innate capacity (γ_m) and finite rate (λ) of population increase were 0.095 and 1.10, respectively.
