The total area of forest crops in Brazil is 9.55 million hectares, of which 7.5 million hectares are . These crops are the most productive in the world, but may suffer losses due to exotic pests, including Moore (Hemiptera: Aphalaridae) found in Brazil since 2003. Interactions between plants and insect pests may led to the selection of resistant genotypes. species are either susceptible or resistant to this pest group, but the damage they suffer needs to be evaluated. The objective was to determine possible leaf anatomy indicators of different species associated with infestations, focusing on plant resistance to this pest. The study was carried out with , , and saplings infested or not by eggs and nymphs. Eighteen anatomical characteristics of the leaves of these plants were analyzed. The number of stomata on the adaxial and abaxial sides and the glandular area in the central leaf vein are associated with greater or lesser infestation by in the genotypes.
巴西的林木作物总面积为 955 万公顷，其中 750 万公顷为桉树。这些作物的生产力在世界上是最高的，但可能因外来害虫而遭受损失，包括自 2003 年以来在巴西发现的 Moore（半翅目：蚜科）。植物和昆虫之间的相互作用可能导致抗性基因型的选择。某些物种对该害虫群体敏感或有抗性，但需要评估它们所遭受的损害。本研究的目的是确定与 Moore 侵染相关的不同桉树品种的可能叶片解剖学指标，重点是植物对这种害虫的抗性。该研究使用了桉树苗进行，这些树苗被 Moore 卵和若虫侵染或未侵染。分析了这些植物叶片的 18 个解剖学特征。叶片上、下表面的气孔数量和中央叶脉的腺区与桉树基因型中 Moore 侵染的严重程度有关。
