عنوان انگلیسی Effect of Eight Cucumis Genotypes on Life Table and Population Growth Parameters of Melon Aphid: An Approach to Assess Antibiosis Resistance
چکیده انگلیسی مقاله The effect of eight Cucumis L. (Cucurbitaceae) genotypes, including native cucumber genotypes (Hormozgan, Bushehr and Gilan), greenhouse cucumber genotypes (Girtap, Negeen, Sepehr and Pouya) and Armenian cucumber (Cucumis melo var. flexuosus) was studied on the life table and population growth parameters of Aphis gossypii Glover to evaluate antibiosis resistance. The experiment was conducted at 25±1°C, 60±10% RH and a photoperiod of 16:8 hour (L:D). The data were analyzed by Two-Sex MSChart program. The most pre-adult mortality (22.6 %) and the shortest total life span (14.5 days) were recorded for ‘Bushehr’. The net Reproductive rate (R0) ranged from 43.70 for ‘Bushehr’ to 92.39 nymphs per individual in the case of ‘Pouya’. The lowest value of the intrinsic rate of increase (r) and the finite rate of increase (λ) was observed in ‘Gilan’ (0.378 and 1.460 day−1, respectively) and the highest in ‘Pouya’ (0.471 and 1.602 day−1, respectively). The maximum and minimum mean generation Times (T) were 10.20 and 9.23 days in ‘Gilan’ and ‘Negeen’, respectively. On the basis of these parameters, ‘Gilan’ had the highest antibiosis resistance to A. gossypii. Information on life table of pests and subsequent host resistance evaluation improves IPM programs and leads us to genotype selection for crop breeding programs.
