The mealy almond aphid, Hyalopterus amygdali (Hemiptera: Aphididae), is an important pest that causes severe damage to almond in Iran. This research studied the life table and population growth parameters of H. amygdali on five almond cultivars: ‘Mamaei’, ‘Rabie’, ‘Ferragnes’, ‘Shahrood 7’, and ‘Shahrood 21’. The experiment was conducted in an incubator at 25 ± 1 °C, 50 ± 5% RH, and a photoperiod of 14:10 hours (L:D). The data were analyzed using the Two-Sex MSChart program. Based on the results, the longest lifespan of the adult aphid was recorded on ‘Mamaei’ (4.11 days), while the shortest was on ‘Shahrood 21’cultivar (1.89 days). The net reproductive rate (R0) ranged from 6.42 for ‘Mamaei’ to 0.2 nymphs per individual in ‘Shahrood 21’. ‘Mamaei’ cultivar showed the highest values of the intrinsic rate of increase (rm) and the finite rate of increase (λ) (0.245 and 1.278 day−1, respectively), along with the shortest duration of the immature stages (5.79 days). In contrast, ‘Shahrood 21’ showed the lowest values of rm and λ (-0.183 and 0.832 day−1, respectively) and the longest duration of the immature stages (7.72 days). Based on the findings, ‘Mamaei’ and ‘Shahrood 21’ cultivars were considered the most suitable and unsuitable hosts for the development and reproduction of H. amygdali, respectively.
