摘　　要：Ecological interactions between plants and insects are of paramount importance for the maintenance of biodiversity and ecosystem functioning.Herbicides have long been considered a threat to plant and insect populations,but global increases in intensive agriculture and availability of herbicide-resistant crops have intensified concerns about their full impact on biodiversity.Here,we argue that exposure to sublethal herbicide doses has the potential to alter plant-insect interactions as a result of disruptions in their chemical communication.This is because herbicides interfere with biosynthetic pathways and phytohormones involved in the production of several classes of plant volatiles that mediate plant-insect chemical communication.Sublethal herbicide doses can modify the morphological and life-history plant traits and affect interactions with insects.However,the potential changes in plant volatiles and their consequences for plant-insect chemical communication have not yet received as much attention.We discuss how target-site(disruptors of primary metabolism)and non-target-site(synthetic auxins)herbicides could alter the production of plant volatiles and disrupt plant-insect chemical communication.We suggest research avenues to fill in the current gap in our knowledge that might derive recommendations and applied solutions to minimize herbicides'impacts on plant-insect interactions and biodiversity.
