“…The ones included here stand out in that all but one of them use none of the methods we scored for, merely include the phylogeny itself, and mostly simply compare its topology to a dendrogram based on VOCs. One study instead reconstructs compounds on the phylogeny (Guitton et al, 2018), and one includes them to improve tree inference (Mercer et al, 2015). All but two of these studies find that VOC clustering more or less mirrors phylogenetic relationships (e.g., Jiang et al, 2006; Xavier et al, 2021), suggesting that species do not only have unique VOC bouquets but that those also seem to reflect shared ancestry (i.e., more closely related species have more similar bouquets).…”

The astonishing diversity of plants and insects and their entangled interactions are cornerstones in terrestrial ecosystems. Co-occurring with species diversity is the diversity of plant secondary metabolites (PSMs). So far, their estimated number is more than 200 000 compounds, which are not directly involved in plant growth and development but play important roles in helping plants handle their environment including the mediation of plant-insect interactions. Here, we use plant volatile organic compounds (VOCs), a key olfactory communication channel that mediates plant-insect interactions, as a showcase of PSMs. In spite of the cumulative knowledge of the functional, ecological, and microevolutionary roles of VOCs, we still lack a macroevolutionary understanding of how they evolved with plant-insect interactions and contributed to species diversity throughout the long coevolutionary history of plants and insects. We first review the literature to summarize the current state-of-theart research on this topic. We then present various relevant types of phylogenetic methods suitable to answer macroevolutionary questions on plant VOCs and suggest future directions for employing phylogenetic approaches in studying plant VOCs and plant-insect interactions. Overall, we found that current studies in this field are still very limited in their macroevolutionary perspective. Nevertheless, with the fast-growing development of metabolome analysis techniques and phylogenetic methods, it is becoming increasingly feasible to integrate the advances of these two areas. We highlight promising approaches to generate new testable hypotheses and gain a mechanistic understanding of the macroevolutionary roles of chemical communication in plant-insect interactions.
