Latreille (Chrysomelidae, Galerucinae, Alticini) is a very large genus of phytophagous insects, with more than 700 species distributed in all zoogeographical regions. Patterns of host use have been a central topic in phytophagous insect research. In this study a first assessment is provided to test the hypothesis that host-plant association is phylogenetically conserved in Western Palaearctic species. Maximum Likelihood and Bayesian Inference methods were used to infer a phylogeny based on DNA sequence data from two mitochondrial genes from 52 species from the Western Palaearctic. In agreement with the host phylogenetic conservatism hypothesis, a strict association between most of the recovered clades and specific plant families was found, except for species associated with Boraginaceae. Low phylogenetic resolution at deep nodes limited the evaluation of whether closely related clades are associated with the same plant family or to closely related plant families.
拉特瑞叶属（叶甲科，叶甲亚科，跳甲族）是一个非常大的植食性昆虫属，有700多种分布在所有动物地理区域。寄主利用模式一直是植食性昆虫研究的核心主题。在本研究中，我们进行了首次评估，以检验寄主植物关联在古北界西部物种中在系统发育上具有保守性这一假设。我们使用最大似然法和贝叶斯推断法，基于来自古北界西部52个物种的两个线粒体基因的DNA序列数据推断系统发育。与寄主系统发育保守性假设一致，我们发现除了与紫草科相关的物种外，大多数恢复的分支与特定植物科之间存在严格关联。深层节点处较低的系统发育分辨率限制了对密切相关分支是否与同一植物科或密切相关植物科相关联的评估。
