Tetranychus ludeni damages the sweet potato. Pest development can vary between plant genotypes. The objective was to identify the preference of Tetranychus ludeni for Ipomoea batatas genotypes, from the germplasm bank at the Universidade Federal dos Vales do Jequitinhonha e Mucuri (UFVJM). Natural infestations of this mite were observed on 54 sweet potato genotypes in potted, in a greenhouse. Three mite-infested leafs of each genotype were collected and analyzed. The red mite showed different population density rate in genotypes. The BD 29 genotype was found to be highly susceptible, the BD 08, BD 57, BD 17 and Espanhola genotypes were moderately susceptible, and the others forty-nine genotypes showed low susceptibility to the mite.
卢德叶螨会损害甘薯。害虫的发育在不同植物基因型之间可能会有所不同。目的是从热基蒂尼奥尼亚和穆库里河谷联邦大学（UFVJM）的种质库中确定卢德叶螨对甘薯基因型的偏好。在温室中，对54种盆栽甘薯基因型上这种螨的自然侵染情况进行了观察。收集并分析了每种基因型的三片螨害叶片。红螨在不同基因型中表现出不同的种群密度率。发现BD 29基因型高度易感，BD 08、BD 57、BD 17和西班牙基因型中度易感，其他49种基因型对该螨表现出低易感性。
