BACKGROUNDPhthorimaea absoluta, a highly destructive invasive pest, poses a significant threat to tomato production globally. Exploring alternative control methods, such as host plant resistance can contribute to diminish reliance on insecticides and promote sustainable integrated pest management (IPM) practices. Thus, the identification of new P. absoluta‐resistant tomato cultivars and potential wild sources for breeding programmes remains imperative. We evaluated the effect of 19 tomato genotypes, comprising 16 domesticated varieties and three wild tomato species, on oviposition output of female P. absoluta, as well as on larval performance under no‐choice conditions using detached leaves. We also characterized and quantified glandular and nonglandular trichomes, exploring their potential correlation with the response of P. absoluta to the tomato plants.RESULTSGenerally, fewer eggs were oviposited on domesticated plants, whereas the wild tomatoes Solanum arcanum and S. neorickii and the domesticated tomato Corona F1 impaired larval development. The pest larvae consumed a limited area of leaflets from S. arcanum and S. neorickii compared to other genotypes, leading to the lowest weights in both male and female pupae. All tomato plants exhibited a prevalence of nonglandular over glandular trichomes, except for S. arcanum, which exhibited a higher abundance of glandular trichomes. Although higher trichome density correlated with longer larval settlement on the leaflets, it did not influence female oviposition.CONCLUSIONOur findings demonstrate that the wild tomatoes S. arcanum and S. neorickii could be considered as potential sources for breeding programmes, and the domesticated Corona F1 could offer IPM options against P. absoluta. © 2024 The Author(s).

番茄潜叶蛾 Phthorimaea absoluta 对野生和驯化番茄基因型的响应


背景Phthorimaea absoluta 是一种极具破坏性的入侵性害虫，对全球番茄生产构成重大威胁。探索替代控制方法，例如寄主植物抗性，有助于减少对杀虫剂的依赖，并促进可持续的有害生物综合治理 （IPM） 实践。因此，确定新的抗 P. absoluta 番茄栽培品种和潜在的野生来源以进行育种计划仍然势在必行。我们评估了 19 种番茄基因型（包括 16 个驯化品种和 3 个野生番茄品种）对雌性 P. absoluta 产卵量的影响，以及使用分离叶在无选择条件下的幼虫性能。我们还表征和量化了腺体和非腺体毛状体，探讨了它们与 P. absoluta 对番茄植株的反应的潜在相关性。结果一般来说，驯化植物的产卵较少，而野生西红柿 Solanum arcanum 和 S. neorickii 以及驯化西红柿 Corona F1 损害了幼虫发育。与其他基因型相比，害虫幼虫消耗的来自 S. arcanum 和 S. neorickii 的小叶面积有限，导致雄性和雌性蛹的重量最低。所有番茄植株都表现出非腺毛多于腺毛的普遍性，除了 S. arcanum，它表现出较高的腺毛丰度。尽管较高的毛状体密度与较长的幼虫在小叶上的定居时间相关，但它不会影响雌性产卵。结论研究结果表明，野生西红柿 S. arcaneum 和 S. neorickii 可以被视为育种计划的潜在来源，驯化的 Corona F1 可以提供针对 P. absoluta 的 IPM 选择。© 2024 作者。 由John Wiley & Sons Ltd代表化学工业协会出版的《害虫管理科学》。
