Species Pseudophilippia quaintancii

Description
Adult -- female approximately 2 mm long; hemispherical and greenish-brown body; covered with a thick layer of fleecy white wax.
Importance
Woolly pine scale populations occasionally become noticeable on single or small groups of trees. Severe feeding damage can cause branch dieback. Death is rare unless accompanied by other stress factors.
Number of Generations: 1 or 2 generation per year.
Signs of Infestation
Masses of woolly wax at base of needles and on shoots. Sooty mold fungi may blacken needles and shoots.
Control
Natural control factors usually keep scale populations at low levels. Promote tree vigor and health to aid recovery. Use an approved insecticide for high value trees or especially damaging scale populations.
