Pemphigus populiramulorum
Poplar Twig Gall Aphid
Pemphigus populiramulorum is a gall-forming aphid in the family Aphididae, known from poplar (Populus) hosts. It induces distinctive twig galls on its primary host. The species has a complex life cycle involving host alternation, though specific secondary host details are not well documented in available sources. It has been confused with other root-feeding Pemphigus species in informal literature.
