Manipulating the odorscape of insects is a key component of most pest control strategies. It can be achieved using natural chemical products such as those emitted by nonhost plants (Conchou et al., 2019). In particular, companion plants can disrupt the pest olfactory environment, owing to the chemical masking properties and/or repelling effects of non-host volatile organic compounds (VOCs) they naturally emit when associated with focal crops (Parker et al., 2013). Exploiting other sources of non-host plantderived odors can be attained with essential oils (EOs) that provide a wide range of bioactive compounds. Distilled from plants, EOs are highly volatile secondary metabolites that may play a key role in plant-insect interactions, such as alkaloids, amides, chalcones, flavones, kawapirones, lignans, neolignans, or phenols (
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
