Pine needle scale

The pine needle scale (Chionaspis pinifoliae Fitch). - Occurs generally in the United States on leaves of pine, and sometimes other evergreens.
Female scale white, narrower than scurfy scale but varying to fit the width of the leaf; male scale much smaller. When abundant, whole branches may appear as though their leaves had been sprayed with whitewash.

Two generations a year, purplish crawling young appearing in the Northern states about the middle of May and the first of September, at which times spray with a miscible oil or with nicotine sulfate as for the oyster-shell scale, but taking care, in the case of the oil, to use one prepared for application to evergreens, as these are more sensitive to oils than deciduous trees.
