Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) is a serious pest originating from South America that affects tomato production in many countries, particularly in Iran (since 2010). In this study, by using age-stage, two-sex life-table parameters, the resistance of seven tomato cultivars, namely, 'Primo Early', 'Rio Grande', 'Cal JN3', 'Petomech', 'Early Urbana Y', 'Super 2270', and 'Super Strain B' to T. absoluta, was evaluated under laboratory conditions (25 ± 1 °C, 60 ± 5% RH, and a photoperiod of 16:8 (L:D) h). Larval and pupal periods were longest on Early Urbana Y, 13.86 and 6.52 d, respectively, and shortest on Cal JN3, 10.92 and 5.5 d, respectively. The longest and shortest development times of immature stages lasted 26.42 and 20.83 d on Early Urbana Y and Cal JN3, respectively. Male and female adult longevity was longest on Early Urbana Y, 30.42 and 38.52 d, respectively, and shortest on Cal JN3, 11.67 and 18.8 d, respectively. The net reproductive rate (R0) ranged between 80.94 (Cal JN3) and 45.87 (Primo Early) offspring. The lowest and the highest values of the intrinsic rate of increase (r) and finite rate of increase (λ) were on Early Urbana Y and Cal JN3, 0.1052 and 0.1522 and 1.1109 and 1.1644 d-1, respectively. The mean generation time (T) on different cultivars varied from 30.47 to 37.28 d. Our results indicated that Cal JN3 was the most susceptible to infestation and Primo Early and Early Urbana Y were the most resistant to T. absoluta among the tomato cultivars tested.
番茄潜叶蛾（Tuta absoluta (Meyrick)）（鳞翅目：麦蛾科）是一种原产于南美洲的严重害虫，影响许多国家的番茄生产，尤其是在伊朗（自2010年以来）。在本研究中，通过使用年龄-阶段两性生命表参数，在实验室条件（25±1°C、60±5%相对湿度、光周期16:8（光照：黑暗）小时）下评估了七个番茄品种，即‘Primo Early’、‘Rio Grande’、‘Cal JN3’、‘Petomech’、‘Early Urbana Y’、‘Super 2270’和‘Super Strain B’对番茄潜叶蛾的抗性。幼虫期和蛹期在‘Early Urbana Y’上最长，分别为13.86天和6.52天，在‘Cal JN3’上最短，分别为10.92天和5.5天。未成熟阶段最长和最短的发育时间在‘Early Urbana Y’上为26.42天，在‘Cal JN3’上为20.83天。雄性和雌性成虫寿命在‘Early Urbana Y’上最长，分别为30.42天和38.52天，在‘Cal JN3’上最短，分别为11.67天和18.8天。净生殖率（R0）在80.94（‘Cal JN3’）至45.87（‘Primo Early’）个后代之间。内禀增长率（r）和周限增长率（λ）的最低值和最高值分别在‘Early Urbana Y’和‘Cal JN3’上，分别为0.1052和0.1522以及1.1109和1.1644 d-1。不同品种的平均世代时间（T）在30.47至37.28天之间变化。我们的结果表明，在测试的番茄品种中，‘Cal JN3’最易受侵害，‘Primo Early’和‘Early Urbana Y’对番茄潜叶蛾最具抗性。
