There has been a resurgence in the cultivation of industrial hemp, Cannabis sativa L., in the United States since the recent legalization of the crop. This increased cultivation is expected to facilitate increased population and spread of several arthropods (pest and beneficial) associated with the plant. Arthropod pests of hemp will facilitate a decline in the quality of industrial hemp used for several purposes including production of fiber, grain, and cannabidiol (CBD). The pests target highly marketable parts of the plant such as flower, stalk, and leaves. Thus, proper management of the pests is essential to achieve a substantial yield of the crop. Pest management strategies for this crop in the United States was earlier reviewed by different authors. In this review, we provide updates on various arthropods associated with industrial hemp in the United States and examine the potential impact of climate change on corn earworm, a major insect pest of the plant. The arthropods reviewed here are from 49 families. Most of them are pests to hemp plants, some are beneficial, while the status of others is yet to be determined as either pests or beneficials on the plant. The identified key pests include corn earworm, Eurasian hemp borer, cannabis aphid, hemp russet mite, grasshoppers, and many other phytophagous species.
