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.

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.

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.

The Spruce Budworm in Maine in 1968

Problem Addressed: Spruce budworm in Maine in 1968
Goal(s)/Objective(s): Check on budworm development, larval and egg mass surveys, and aerial surveys for defoliation
Key Findings: The spruce budworm infestation can be expected to continue and probably intensify in the Oxbow area during 1969, given favorable weather conditions for the insect.

The Uptake of Sevin by Pacific Oysters and Bottom Muds

Problem Addressed: The insecticide Sevin's effects
Key Findings: While Sevin residue in bottom mud was present at a higher level than in oysters following direct application, it declined rapidly to a barely detectable level in 8 days and disappeared by the 16th day.

Zectran Pilot Test to Control Spruce Budworm in Belmont and Chamberlain Creeks, Blackfood River Drainage, Montana

Problem Addressed: Spruce Budworm
Goal(s)/Objective(s): Determine the aerial transport of smoke within the spray areas, and optimum spray time.
Key Findings: Budworm population was reduced 47.8 ± 5.5 in Chamberlain Creek and 70.0 ± 4.2 in Belmont Creek.
