Abstract

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.
