Grapholita delineana
Eurasian hemp moth, hemp moth, hemp borer
Grapholita delineana, commonly known as the Eurasian hemp moth or hemp borer, is a tortricid moth species in the family Tortricidae. It has emerged as a significant economic pest of hemp (Cannabis sativa) in the United States following the crop's legalization for commercial production. The species is native to Eurasia but has established populations in North America where it can cause substantial damage to hemp crops, particularly those grown for cannabidiol (CBD) production.
Phorodon cannabis
Cannabis Aphid, Hemp Aphid
Phorodon cannabis is a monophagous aphid pest specialized on hemp (Cannabis sativa), causing significant damage in field and greenhouse cultivations. Native to Eurasia and North Africa, it was first detected in North America in 2016 and has since spread to multiple U.S. states and Canada. The species feeds on phloem sap, causing plant wilting, yellowing, and yield reduction, and transmits Cannabis Streak Virus. Optimal development occurs at 25°C, with mild abiotic stress paradoxically stimulating reproduction via hormesis.
