Status of Products Under Development & Research Trials Proposed for the 1981 Field Season

Goal(s)/Objective(s): Review the status of a number of the pest control products at various stages in the Institute's mill at Sault Ste. Marie and propose for further testing and development during the 1981 field season.
Key Findings: New methodologies for carbamate insecticides have been developed and studies on the accumulation of fenitrothion in forestry substrates for up to 5 consecutive years of application. The studies suggest that it takes several years of treatment before significant amounts accumulate.

Long-term Effects of Fenitrothion Spray Programs on Non-Target Terrestrial Arthropods

Problem Addressed: Use of insecticides as spruce budworm control
Goal(s)/Objective(s): Describe the methods of approach and the interim results to questions regarding spray programs against spruce budworm
Key Findings: The perennial trends of densities in this array of predatory, phytophagous, and fungivorous arthropods do not support the hypothesis that fenitrothion has a profound influence on the community resident in balsam fir crowns.
