    Neodiprion sertifer (Geoffroy) larval populations were treated with high and low doses of a nucleopolyhedrosis virus (NPV) product, Neochek-S. Larval population reduction due to Neochek-S was well over 90% in all sprayed plots 28 days after application, whereas overall protection of Pinus resinosa (Ait.) foliage was 94.0 ± 1.6%. The difference between doses was insignificant with respect to population reduction or foliage protection. A dose rate of 2.5 x 109 polyhedral inclusion bodies of N. sertifer NPV/ha, by ground application, provided acceptable control in a plantation infested with moderate to dense populations of the insect.
