为综合评价核桃品种对核桃暗脉蚜Panaphis juglandis（Goeze）的抗性，在田间条件下收集了5个核桃品种（Akca I、钱德勒、Fernette、Fernor和Pedro）上饲养的核桃暗脉蚜Panaphis juglandis（Goeze）生命表数据。发育时间，存活率和繁殖力的原始数据进行了分析，使用年龄阶段，两性生命表，占变量的发展速度和阶段分化的个体。由于该物种的未成熟发育时间较长，成年寿命较短，繁殖期较短，繁殖力较低，净繁殖率（R-0 = 5.9后代），内在增长率（r = 0.0983d（1）），有限速率（λ = 1.1034 d（1））在Fernor品种上饲养时最低，而在Akca I品种上饲养的蚜虫表现出最高的种群参数（R-0 = 18.0子代，r = 0.2031 d（-1），λ = 1.2252 d（-1））。根据种群特性，弗诺是一个不太适合核桃的发育和繁殖的品种。我们还展示了使用自举法分析发育时间，寿命，繁殖力和其他参数的标准误的优势。我们的研究结果表明，害虫的发展，生存和繁殖的基础上的龄期，两性生命表的人口统计分析提供了一个全面的评估害虫生长潜力的不同作物品种。
To provide a comprehensive evaluation of walnut cultivar resistance to the dusky-veined walnut aphid, Panaphis juglandis (Goeze), we collected the life table data of this aphid reared on five cultivars of walnut ('Akca I,' 'Chandler,' 'Fernette,' 'Fernor,' and 'Pedro') under field conditions. The raw data of the developmental time, survival rate, and fecundity was analyzed using the age-stage, two-sex life table to account for the variable developmental rate and stage differentiation among individuals. Due to the species' longer immature developmental time, shorter adult longevity, shorter reproduction period, and lower fecundity, the net reproduction rate (R-0 = 5.9 offspring), intrinsic rate of increase (r = 0.0983 d (1)), and finite rate (lambda = 1.1034 d (1)) were the lowest when aphids were reared on the Fernor cultivar, while those reared on Akca I exhibited the highest population parameters (R-0 = 18.0 offspring, r = 0.2031 d(-1), and lambda = 1.2252 d(-1)). Based on the population characteristics, Fernor is a less favorable cultivar for the development and reproduction of P. juglandis. We also demonstrated the advantages of using bootstrapping for the analysis of standard errors of developmental time, longevity, fecundity, and other parameters as well. Our results indicated that demographic analysis of pest development, survival, and reproduction based on the agestage, two-sex life table offers a comprehensive assessment of pest growth potential on different crop cultivars.
