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.

Distribution and presistence of fenitrothion residues in foliage, soil and water in larose forest.

Problem Addressed: Insecticide residues in Larose forest.
Goal(s)/Objective(s): Summarize an operational experiment carried out in Larose Forest to study the persistence of aerially applied fenitrothion and its metabolites (the oxon analgue and 4-nitro-cresol) in white spruce foliage, soil and water samples collected from sprayed areas.
Key Findings: Degradation and persistence of fenitrothion findings are in reasonable agreement with those for the same chemical used in N.B. forests.

Reduction of Reproductive Potential in Spruce Budworm (Lepidoptera: Tortricidae) by a Chitin-Inhibiting Insect Growth Regulator

Goal(s)/Objective(s): Examine the potential of UC-62644 to reduce the reproductive capabilities of spruce budworm that have been exposed to sublethal concentrations of this chemical during the last larval instar.
Key Findings: The dosages of UC-62644 incorporated into the test diets were sublethal and did not adversely affect larval or pupal survival.
