Small walnut aphid (Chromaphis juglandicola (Kaltenbach) (Hemiptera: Aphididae) is important pest in walnut orchards in Lake Van Basin, Turkey. In this study, the life-table parameters reflecting population growth rate and predation rate of Chrysoperla carnea (Stephen) (Neuroptera: Chrysopidae), which is one of the important predators of the pest, were determined. Life table parameters were estimated according to age-stage, two-sex life table method. Variances and standart errors of population parameters were obtained according to Bootstrap method. The values obtained for the intrinsic rate of increase (r), finite rate of increase (λ), net reproductive rate (R0) and mean generation time (T) were 0.072 d−1, 1.070 d−1, 62.48 offspring and 57.16 d, respectively of C. carnea fed on Chromaphis juglandicola. The net predation rate (C0) was determined as 212.9 aphids. Pradation projection was performed by using timing program to prevent the predator’s decrease in predation capacity and to determine the most appropriate release quantities and the appropriate interval between releases (to fill predation gaps) for biological control. The possible effects of the findings on the bio-controls of Chromaphis juglandicola by C. carnea were discussed. Results obtained can be used in pest management program that will be prepared for this pest.

捕食率与以小核桃蚜虫 (Chromaphis juglandicola) (Kalt.) 为食的 Chrysoperla carnea (Stephen)（神经翅目：Chrysopidae）的生命表相关联（半翅目：蚜科）：具有种群和捕食预测

净捕食率 (C0) 确定为 212.9 只蚜虫。捕食预测是通过使用计时程序进行的，以防止捕食者捕食能力下降，并确定最合适的释放量和释放之间的适当间隔（以填补捕食间隙）以进行生物控制。讨论了这些发现对 C. carnea 对 Chromaphis juglandicola 的生物防治可能产生的影响。获得的结果可用于为此害虫准备的害虫管理计划。讨论了这些发现对 C. carnea 对 Chromaphis juglandicola 的生物防治可能产生的影响。获得的结果可用于为此害虫准备的害虫管理计划。讨论了这些发现对 C. carnea 对 Chromaphis juglandicola 的生物防治可能产生的影响。获得的结果可用于为此害虫准备的害虫管理计划。
