What is the primary host genus for the Woolly Apple Aphid (*Eriosoma lanigerum*)?
Answer
*Malus* genus
The Woolly Apple Aphid, scientifically known as *Eriosoma lanigerum*, exhibits an overwhelming association and preference for host plants belonging specifically to the *Malus* genus. This genus encompasses domestic apples, which are their most common hosts, as well as crabapples. While woolly aphids generally can infest various woody plants and related species within the broader Rosaceae family might sometimes show infestation, the specific species *E. lanigerum* is overwhelmingly characterized by its specialization on *Malus* species. This host specificity is a crucial factor in determining where monitoring efforts should be concentrated for this particular pest.
