Aphis pomi
apple aphid, green apple aphid
Aphis pomi, the green apple aphid, is a small sap-sucking insect specialized on pomoideous host plants in the Rosaceae family, particularly apple (Malus domestica). It is autoecious, completing its entire life cycle on a single host species. The species reproduces primarily through parthenogenesis during the growing season, with sexual forms appearing only in autumn to produce overwintering eggs. It is morphologically similar to Aphis spiraecola but can be reliably distinguished by the length of the ultimate rostral segment.
