Life table demography and population growth of dusky-veined walnut aphid, Panaphis juglandis (Goeze) (Hem., Callaphididae) on different walnut cultivars

Abstract: The effect of five cultivars of walnut on the life table demography and population growth of dusky-veined walnut aphid were tested at 25 ± 1 °C, 60 ± 10% r.h. and 16 L:8 D photoperiod in a controlled temperature room. Experiments were carried out using potted walnut plants and plexiglas clip-cells (20 x 10 mm) with their upper side covered by muslin. Developmental time, survival and fecundity data were analyzed based on the age-stage, two-sex life table. Results showed that aphids had the lowest performance on the Fernor cultivar.
