Aphis illinoisensis
grapevine aphid
Aphis illinoisensis, commonly known as the grapevine aphid, is a phytophagous insect native to North America that has become invasive in Mediterranean regions and other grape-growing areas worldwide. It is a documented vector of Grapevine vein clearing virus (GVCV), transmitting the pathogen from wild Vitaceae to cultivated grapevines. The species exhibits holocyclic life cycle characteristics with documented overwintering on Viburnum species. Its invasive expansion across Europe, North Africa, and the Middle East has prompted biocontrol research using native parasitoids and entomopathogenic bacteria.
