Interpretive Summary: Industrial hemp production in the USA is increasing, and with it the list of insects colonizing the crop. In this research, we report new records of three aphid species recovered on industrial hemp in East Lansing, Michigan in 2020. The aphid species identification was completed through morphological characteristics and DNA barcoding. For the suction trap collections, between 2017 and 2020, the number of individual sites detecting cannabis aphid increased, and as well as the number of sites with multiple weeks of detections. The timing of detection changed, from only late season 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. This information is important to hemp growers, consultants of hemp growers, and ecologist and entomologists that are interested in monitoring insect pests over time and geographic space.

Technical Abstract: Industrial hemp (Cannabis sativa L.) production in the USA is increasing, and with it the list of insects colonizing the crop. In this communication, we report new records of Aphis craccivora Koch, Aphis gossypii Glover and Myzus persicae (Sulzer) on industrial hemp in East Lansing, Michigan in fall 2020. The identification was performed through aphids’ morphology, and two male individuals were identified through DNA barcoding, Aphis fabae Scopoli and Aphis spiraecola Patch. About the suction trap collections, between 2017 and 2020, the number of individual sites detecting P. cannabis increased, 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.
