• •Insects use a wide variety of chemical and visual cues to avoid encounters with potential predators.•Changes in prey behavior or physiology in response to predation threat are called non-consumptive effects (NCEs).•NCEs can alter prey population dynamics with cascading effects to other trophic levels.•The small scale of current experimentation limits our ability to understand these complex interactions.•Scaling-up experiments in time and space is necessary to inform the use of NCEs for pest management. Non-consumptive effects (NCEs) of predators on prey is an important topic in insect ecology with potential applications for pest management. NCEs are changes in prey behavior and physiology that aid in predation avoidance. While NCEs can have positive outcomes for prey survival there may also be negative consequences including increased stress and reduced growth. These effects can cascade through trophic systems influencing ecosystem function. Most NCEs have been studied at small spatial and temporal scales. However, recent studies show promise for the potential to manipulate NCEs for pest management. We suggest the next frontier for NCE studies includes manipulating the landscape of fear to improve pest control, which requires scaling-up to field and landscape levels, over ecologically relevant time frames.
