A Cooperative Pilot Study of the Insecticide Sumithion

Problem Addressed: Insecticide effects
Goal(s)/Objective(s): Evaluate the effectiveness of a selected treatment of Sumithion in controlling the spruce budworm and the effect of Sumithion on birds, fish, and aquatic invertebrates
Key Findings: The stonefly larvae seem to have suffered the greatest reduction.
Recommendation: In late spring of 1969, samples of aquatic insects in the test and control stream should be undertaken to determine the recovery of fish food organisms.
