Phorodon
Phorodon is a genus of aphids in the family Aphididae containing at least two economically significant species: Phorodon humuli (damson-hop aphid) and Phorodon cannabis (cannabis aphid). The genus exhibits host specialization, with P. humuli feeding on hop (Humulus lupulus) and P. cannabis restricted to hemp and cannabis (Cannabis sativa). Both species are recognized agricultural pests in their respective cropping systems. P. humuli has been extensively studied for insecticide resistance mechanisms involving elevated esterase activity, while P. cannabis has emerged as a concern in the expanding North American hemp industry following legalization.
