Environmental Studies in the Use of Accothion for Spruce Budworm Control (1971)

Problem Addressed: Effect on wildlife from spraying against Spruce Budworm

Goal(s)/Objective(s): Effects of the insecticide Accothion birds, mammals, fish, and amphibians

Key Findings: Observations in the spray area were made on reactions to Accothion of a great variety of species of flora and fauna present. Accothion showed observable effects on some insects but not on other insects; nor on plants, birds, minnows in a confined pool, tadpoles, frogs, toads, and salamanders.

Monitoring the Effects of Spraying for Spruce Budworm on Songbirds in Maine, 1979

Problem Addressed: Effect on Maine songbirds by spraying against Spruce Budworm

Goal(s)/Objective(s): Test sampling techniques developed by US. Fish & Wildlife Service for measuring bird populations over large regions will suffice, compare areas whose past histories are known to see differences in songbird populations, and establish baseline against which to compare data gathered in future years to see whether secular trends occur in songbird populations and whether differential changes occur in the populations of species more vs. less exposed to the pesticides.
