Description |
Adult - female approximately 3 mm long; elongated white body with one yellowish-orange tip. |
Importance |
Pine scale populations often become noticeable, especially on ornamental trees. High population levels and feeding damage may lead to dead foliage and branches. |
| Number of Generations: |
1
or 2 generation per year. |
Signs
of Infestation |
Discoloration of foliage: reddish-yellow to gray. Pine needles may appear white due to high density of scales on the foliage. |
Control |
Predators, parasites, and unfavorable weather usually keep scale populations at low levels. Population flare-ups do occur, but generally subside due to natural control factors. Use an approved insecticide for high-value trees or especially damaging scale population. |
