Phorodon cannabis

Cannabis aphid

General

Although it was first described in 1860, the cannabis aphid (Phorodon cannabis; a.k.a. bhang aphid or hemp aphid) is a very new pest to North America. It was first seen on cuttings originating from Colorado in 2016 and is now widespread throughout that state and Oregon. Its range also includes several other states and parts of Canada. The cannabis aphid closely resembles the hop aphid (Phorodon humuli), to the point that microscopic analysis of the head is required to distinguish them. The hop aphid is common in North American hops production; there have been unconfirmed reports of Phorodon humuli developing on cannabis plants, as well.
