Description of Damage Damage is not apparent until large populations have been present for more than 1 or 2 seasons. Occasionally the feeding of scales produces chlorotic, yellowish flecks no the needles, but normally this is not apparent. Heavily infested plants are seriously weakened and may be in a state of decline. Eggs under the scale covers are purplish in color. Crawlers and settled nymphs are reddish brown.
Females are reddish in color beneath the white scale covers.
The first generation crawlers settle on old needles, since new growth is not fully developed until later. Second generation crawlers settle primarily on the current year's growth. Females produce 5-30 reddish purple eggs. Although the number of eggs laid is relatively small, two generations a year permits rapid buildup of infestations. Control Sprays are effective if applied after most eggs have hatched.
