Abstract


Phorodon humuli Schrank, 1801 (Hemiptera: Aphididae), the damson-hop aphid is the most important pest of superterrestrial organs of hop (Humulus lupulus Linné, 1753). The damages produced by this aphid, could be considerable sometimes compromising the yields. The studies on the morphology of this key-pest carried out until present, has contributed to clearing up of some classical aspects of these problems. The research concerning the morphology of damson-hop aphid were carried out between 1998-2019 in Cluj-Napoca (Romania). The various forms of aphid's life cycle were captured, prepared, photographed and measured, with the corresponding description.
