Abstract:

Sevin 4-oil, an oil suspension of carbaryl, was applied by helicopter to forested areas infested by Orgyia pseudotsugata (McDunnough), in western Montana and northern Idaho. Dosage was 2 lb AI/O.75 gal of carrier/acre. Spray was applied to 1st instars in Montana and 3rd and 4th instars in Idaho. Treatments provided a high degree of insect mortality and measurable foliage protection; the residual population did not produce egg masses in sufficient quantity to repopulate infested areas.
