Pineus
Pineus is a genus of adelgids (family Adelgidae) comprising more than 20 described species. These insects are small, sap-feeding hemipterans specialized on conifer hosts, primarily Pinus (pines) and Picea (spruces). Species exhibit complex life cycles with multiple morphological forms, including winged and wingless generations, and some alternate between two host species. Several species are economically significant as pests of forestry and ornamental plantings.
