Spruce Budworm infestations declined in Ontario in 1986. In 1987, moderate-to-severe defoliation is expected to persist throughout most of the area infested in 1986 with some possible expansion along the northern edge of the infestation. The rapid and uniform development of budworm larvae throughout the region and technical problems leading to delays in the program may account for some of the poorer results.
