Hyalopterus
Mealy Plum-Reed Aphids
Hyalopterus is a genus of aphids in the family Aphididae, commonly known as mealy plum-reed aphids. Species in this genus are cosmopolitan pests of stone fruit trees in the genus Prunus, causing damage through direct feeding and virus transmission. The genus has undergone recent taxonomic revision, with molecular and morphometric analyses supporting at least three distinct species: H. pruni, H. amygdali, and H. persikonus (the latter described in 2006). Species boundaries are strongly correlated with host-plant associations.
