Aerial Application of Spruce Budworm Baculovirus: Tests of Virus Strains, Dosages and Formulations in 1977

Problem Addressed: Spruce budworm
Goal(s)/Objective(s): Five plots with a total area of 148 ha were treated with spruce budworm nuclear polyhedrosis virus to test 3 formulations, 2 dosages and 2 strains of virus against the spruce budworm
Key Findings: 750 billion polyhedra/ha gave a population reduction of 92% which is the best result obtained to date with a nuclear polyhedrosis virus treatment on spruce budworm.

Aerial Spraying Operations Against Blackheaded Budworm on Vancouver Island, 1973

Problem Addressed: Spruce budworm and blackheaded budworm outbreak
Goal(s)/Objective(s): An aerial spray project conducted by the Council of Forest Industries of British Columbia and the Province of British Columbia to protect 29,000 acres of hemlock forest on northern Vancouver Island from additional defoliation by an outbreak of blackheaded budworm.
Key Findings: Monitoring of the effects of the operations on non-target organisms revealed that populations of juvenile salmon, songbirds and small mammals suffered no immediate ill effects. However, there was considerable mortality of several families of aquatic and terrestrial insects.

Pilot Control Project to Determine Efficacy of Acephate, Carbaryl, and Trichlorfon Against the Spruce Budworm (Choristoneura fumiferana (Clem.)) in Maine — 1976

Problem Addressed: Insecticide use against spruce budworm
Goal(s)/Objective(s): Conduct a pilot control project to evaluate the efficacy of three different insecticides in reducing larval populations of the budworm and minimizing the amount of defoliation to host trees.
Key Findings: Each of the insecticides could be effectively used against the spruce budworm with minimal and transitory effects on the environment.
