Industrial hemp (Cannabis sativa L.) production in the USA is increasing, and with it the list of insects colonizing the crop. In this article, we report new records of Aphis craccivora Koch 1854, Aphis fabae Scopoli, Aphis gossypiiGlover 1763, Aphis spiraecola Patch 1914 and Myzus persicae (Sulzer 1776) on industrial hemp in East Lansing, Michigan in fall 2020. In addition, between 2017 and 2020, the number of suction trap sites detecting P. cannabisincreased, and as well as the number of sites with multiple weeks of detections. The timing of detection changed, from only late season (fall migrants) in 2017, to catches spanning spring, summer, and fall in 2019 and 2020. These changes likely reflect the increase in industrial hemp production in the landscape in the Midwestern US.
