Cinara is a genus of aphids comprising approximately 200-243 species, commonly known as giant conifer aphids. These insects are specialized feeders on conifers in the families Pinaceae and Cupressaceae, including pines, firs, spruces, cedars, and cypresses. Molecular studies indicate their tribe Eulachnini represents the basal group for other aphids. Several species are significant pests of cultivated Christmas trees, particularly Fraser fir production in the southeastern United States.
