Aquatic Impact Studies by FPMI in Quebec Spruce Budworm Spray Block 305, 1977

Problem Addressed: Use of insecticides to stop spruce budworm
Goal(s)/Objective(s): Determine effect of fenitrothion and aminocarb on lakes and streams
Key Findings: No dramatic adverse effects on lake zooplankton, benthos or fish populations occurred but a significant effect on shallow dwelling baetid mayfly nymphs was indicated.

Aquatic Impact Studies in New Brunswick Forests Treated with Semi-Operational Applications of Matacil Flowable Formulations in 1982

Problem Addressed: Environmental hazards of point source applications of aminocarb flowable formulations to streams.
Goal(s)/Objective(s): Determine impact of double 70.0 g/ha MATACIL 180F + ATLOX 3409F + water and MATACIL 180F + Insecticide Diluent 585 applications under operational conditions to streams within forested areas in New Brunswick.
Key Findings: Effects of applications on stream benthos and indigenous salmonids.

A Preliminary Report on the Effects of a Split Application of Reldan on Aquatic and Terrestrial Ecosystems

Problem Addressed: Application of RELDAN, pesticide
Key Findings: Knockdown of terrestrial invertebrates was slight, involving primarily small flying Diptera, but also Hymenoptera, Araneida and Plecoptera. Effects of the first spray were more pronounced, presumably due to warmer temperatures and increased insect activity.

A History of the Effects of Aerial Forest Spraying in Canada on Aquatic Fauna

Problem Addressed: Pesticide spraying
Key Findings: Much progress has been made in discovering and eliminating undesirable side-effects of forest insect control operation in Canada on aquatic ecosystems, however, the role of many factors related to insecticide toxicity and side-effects still remain vague.

Effect of Pesticides on Cholinesterase from Aquatic Species: Crayfish, Trout and Fiddler Crab

Problem Addressed: Use of pesticides and the development of quantitative assays for low concentrations of these pesticides
Key Findings: Nineteen pesticides were tested for inhibition of cholinesterase activity derived from trout brain, crayfish nervous system and whole fiddler crabs. Inhibition by low concentrations of a few of these pesticides permitted a very sensitive and selective assay. Chlorinated pesticides as a class showed little inhibitory effect on trout and crab cholinesterase. Carbamates strongly inhibit all three enzymes.
