The Effects of Fenitrothion, Matacil and Orthene on Frog Larvae

Problem Addressed: Effects of insecticides used for spruce budworm control on other wildlife.
Goal(s)/Objective(s): Discuss the behavioral repertoire of Rana clamitans tadpoles in the laboratory.
Key Findings: Concentrations detrimental to anuran larvae would never be encountered under normal operational applications of these chemicals.

Impact of the 1974-81 Spruce Budworm Infestation on the Forests of Cape Breton Island

Problem Addressed: Spruce budworm infestation on Cape Breton Island, Nova Scotia beginning in 1974.
Goal(s)/Objective(s): Determine what the overall effects of the SBW infestation on the Island forests was.
Key Findings: Volume of merchantable spruce/fir growing stock was reduced, degree of damage varied by covertype, and over half of the projected living merchantable spruce and fir trees died either during or immediately following the SBW attack.

Report of the 1986 Midcycle Resurvey of the Spruce-Fir Forest in Maine

Problem Addressed: Budworm outbreak effecting 1980 survey of supply and demand for spruce-fir in Maine.
Goal(s)/Objective(s): Validate the earlier forecasts and to update them to account for new or unexpected developments.
Key Findings: Maine forests, at least within the survey region, are adequately stocked with young trees.

Recommendations for Improvement of Spruce Budworm Population and Damage Survey Methods in the State of Maine

Problem Addressed: Spruce budworm in Maine
Goal(s)/Objective(s): Describe egg mass and defoliation survey; to check results of the egg mass survey, obtain more detailed information on budworm populations, and predict damage in the coming year.
Recommendation: Eliminate any branch beating surveys for spruce budworm and not using light trap data when populations are high.

Measurement of Vapour Pressure and Volatility from Foliage of Fenitrothion and Aminocarb

Problem Addressed: Use of insecticides against spruce budworm
Goal(s)/Objective(s): Describe measurements of the vapour pressures of pure and formulated fenitrothion and aminocarb from quartz sand, glass surfaces and plant foliage.
Key Findings: In our initial determinations of VP's from sand saturators, a doubling of the loading with either fenitrothion or aminocarb resulted in ≤2% change in the vapour pressures obtained. This indicated that the vapour space around the quartz particles was saturated and that the values obtained experimentally were equilibrium values under the conditions used.

Getting off the Treadmill: Some Public Concerns About Our Spruce Budworm Program

Problem Addressed: Spruce budworm
Goal(s)/Objective(s): Describe the position and what to do about the issues of the state's responsibility in controlling budworm damage to privately owned forest lands, whether we are on an endless treadmill of spraying, what is being done to the environment and public health in the long term
Key Findings: Spraying of the private sector will end by 1981, will begin promotion of the development of a forest less susceptible to budworm, and will cease using any insecticide that poses distinct dangers to fish or any other nontarget animal or plant.
