Tomato plants are highly susceptible to pests. Among the control methods, genetic improvement with introgression of resistance genes from wild accessions into commercial tomato lines is the best alternative for an integrated pest management (IPM). Thus, the objective of this study was to select tomato genotypes in advanced populations (FBC), with higher levels of acylsugar content, greater recurrent parent genome recovery, and resistance to and inherited from . For pest resistance, bioassays were assessed: nine high-acylsugar genotypes, four low-acylsugar genotypes, and the parents, or 'Redenção', and LA-716. Glandular and non-glandular trichomes were quantified. A negative correlation was measured between acylsugar content in the leaflets and pest behavior. Pest resistance was found in the selected FBC genotypes with high-acylsugar content, indicating that this allelochemical was efficient in controlling the arthropod pests.
番茄植株极易受到害虫侵害。在防治方法中，将野生种质的抗性基因渗入商业番茄品系进行遗传改良是综合害虫管理（IPM）的最佳选择。因此，本研究的目的是在高级群体（FBC）中选择番茄基因型，这些基因型具有较高水平的酰基糖含量、更高的轮回亲本基因组回收率，以及从[未提及的种质]遗传而来的对[未提及的害虫]和[未提及的害虫]的抗性。对于害虫抗性，进行了生物测定：九种高酰基糖基因型、四种低酰基糖基因型，以及亲本[未提及的亲本1]或‘Redenção’和[未提及的亲本2]LA - 716。对腺毛和非腺毛进行了定量分析。在小叶中的酰基糖含量与害虫行为之间测得负相关。在所选的高酰基糖含量的FBC基因型中发现了害虫抗性，这表明这种化感物质在控制节肢动物害虫方面是有效的。
