Cinara cupressi (Buckton, 1881) - (cypress aphid)
This species of conifer aphids is native to North America, but is now widely distributed in other regions. It is a pest of Cupressus and other Cupressaceae. Pine trees (Pinaceae) may be also attacked. Infestations can lead to chlorosis and necrosis, as well as to defoliation and tree death in severe cases. Damage has been widespread and serious in areas that have been recently invaded by the aphid.
In temperate regions, eggs are laid in autumn, overwinter and hatch in spring. Only female aptera develop at that time which propagate parthenogenetically for several generations. In autumn winged females and males develop. These disperse, mate and lay eggs.
The mature aptera are 2-4 mm long and brown with black marks. Cinara cupressi is part of a group of similar and closely related species which includes Cinara sabinae (Gillette and Palmer) and Cinara canadensis Hottes and Bradley (possibly both are synonyms of C. cupressi). See also Cinara cupressivora.
