Threats to food security require sustainable agriculture practices for insect pest management. Conservation biological control (CBC) relies on pest control services provided by local populations of arthropod natural enemies. This review discusses past strategies using chemical ecology in CBC and proposes future directions, including leveraging induced plant defenses and genetically engineered crops.
Threats to food security require novel sustainable agriculture practices to manage insect pests. One strategy is conservation biological control (CBC), which relies on pest control services provided by local populations of arthropod natural enemies. Research has explored manipulative use of chemical information from plants and insects that act as attractant cues for natural enemies (predators and parasitoids) and repellents of pests. In this review, we reflect on past strategies using chemical ecology in CBC, such as herbivore-induced plant volatiles and the push-pull technique, and propose future directions, including leveraging induced plant defenses in crop plants, repellent insect-based signaling, and genetically engineered crops. Further, we discuss how climate change may disrupt CBC and stress the importance of context dependency and yield outcomes.
