Tetranychus urticae Koch (Acari: Tetranychidae) is a major pest species in numerous crops including hop (Humulus lupulus L.). Substantial T. urticae infestation was observed to occur in this recently introduced crop in Brazil. The adoption of less suitable cultivars to the pest species is highly desirable for integrated pest management. We used free-choice trials and two-sex life table analysis to determine the preference and population growth of T. urticae under laboratory conditions using three of hop cultivars currently expanding in Brazil (Mantiqueira, Victoria, and Yakima Gold). We also estimated the density of non-glandular trichomes and lupulin glands found on the abaxial leaf surface of these cultivars and correlated them with performance parameters of T. urticae. Mantiqueira appeared to be the least preferred by adult females for attractiveness and oviposition suggesting existence of antixenosis on this cultivar. Female immature stages developed slower on Yakima Gold and Mantiqueira, but no difference was observed between the latter and Victoria. Fecundity and longevity were significantly lower on Mantiqueira than on Victoria and Yakima Gold. No significant differences were observed among cultivars for intrinsic rate of increase (r), finite rate of increase (λ), and net rate of reproduction (R₀), suggesting the absence of antibiosis. Although, lupilin gland densities were higher on Mantiqueira and Yakima Gold than on Victoria, no significant correlations were observed between these defensive traits and performance parameters of T. urticae. However, 30-day population simulations of T. urticae suggest that Yakima Gold is the least susceptible, Mantiqueira is moderately susceptible, and Victoria is highly susceptible.

Tetranychus urticae Koch（Acari：Tetranychidae）是包括啤酒花（Humulus lupulus L.）在内的多种作物的主要害虫物种。观察到在巴西最近引进的这种作物中发生了大量的荨麻疹。采用不太适合害虫物种的栽培品种对于综合害虫管理是非常可取的。我们使用自由选择试验和两性生命表分析来确定荨麻疹的偏好和种群增长在实验室条件下，使用目前在巴西扩展的三种啤酒花品种（Mantiqueira、Victoria 和 Yakima Gold）。我们还估计了在这些品种的背面叶表面上发现的非腺毛状体和羽扇豆腺的密度，并将它们与T. urticae 的性能参数相关联。Mantiqueira 似乎是成年雌性最不喜欢的，因为它的吸引力和产卵表明该品种存在抗毒素。雌性未成熟阶段在 Yakima Gold 和 Mantiqueira 上发育较慢，但后者和 Victoria 之间没有观察到差异。Mantiqueira 的繁殖力和寿命明显低于 Victoria 和 Yakima Gold。品种间内在增长率无显着差异（r)、有限增长率 ( λ ) 和净繁殖率 ( R ₀ )，表明不存在抗生素。尽管 Mantiqueira 和 Yakima Gold 上的羽扇豆腺密度高于 Victoria，但在这些防御性状与T. urticae 的性能参数之间没有观察到显着的相关性。然而，T. urticae 的30 天种群模拟表明，Yakima Gold 是最不敏感的，Mantiqueira 是中度易感的，而 Victoria 是高度易感的。
