Hemp (Cannabis sativa L.) production has increased globally since the 1990s, presenting a need to identify pests in the crop. Many arthropods have been observed in hemp, but economic importance is unclear for many of them. Several pests are more concerning, including corn earworm, Helicoverpa zea (Boddie), Eurasian hemp borer, Grapholita delineana Walker, beet leafhopper, Circulifer tenellus (Bennett), rice root aphid, Rhopalosiphum abdominalis (Sasaki), and hemp russet mite, Aculops cannabicola (Farkas). While, these pests have caused significant damage in some regions, economic thresholds and economic injury levels have yet to be developed. Despite this, integrated pest management principles can be applied to reduce damage. Chemical management is limited, emphasizing the importance of other strategies, including improved breeding efforts for resistance to pests and the use of biological control agents. Several pests of hemp have been more widely researched, including hemp russet mite, providing an ideal case study.
