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.

Response of Breeding Birds to Aerial Sprays of Trichlorfon (Dylox) and Carbaryl (Sevin-4-Oil) in Montana Forests

Goal(s)/Objective(s): Report the results of a pilot control project with trichlorfon (Dylox) and carbaryl (Sevin-4-Oil), with particular reference to the effects of the chemicals on 20 bird species.
Key Findings: No significant effects of trichlorfon or carbaryl sprays on the numbers of breeding pairs, bird abundance, nest success, mortality rates, or the activities of brain cholinesterase in the breeding population were detected.

Spruce Budworm Defoliation in Relation to Introgression in Red and Black Spruce

Goal(s)/Objective(s): Rating branch samples for severity of budworm damage to 1968 foliage, using 10 defoliation categories ranging from rating one for no defoliation to rating ten for complete defoliation.
Key Findings: Post-cutting regeneration techniques would favor the less shade-tolerant black spruce.

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.
