Chemical communication between plants and insects

The chemical communication between plants and insects plays a pivotal role in shaping plant-insect interactions and ecological networks,making it a vital component in both natural and agricultural ecosystems.Despite the considerable advancements in the field of chemical ecology(Meinwald&Eisner,2008),numerous challenges remain due to its interdisciplinary nature(encompassing evolutionary biology,neurobiology,chemistry,animal behavior,and network ecology),as well as the complexity of chemical communication(including mediating mutualistic and antagonistic relationships,and multifunctional roles at the community level).In this special issue of the Journal of Systematics and Evolution,we present a collection of 10 papers addressing these challenges through original research and comprehensive reviews of relevant subfields.
