Fenitrothion Residues in Honeybees and Their Products Collected From Forested Areas Sprayed with the Insecticide for Budworm Control

Problem Addressed: Fenitrothion effects on honeybees
Goal(s)/Objective(s): Results and observations made in an extensive three-year study program undertaken in 1972 to determine the effect of fenitrothion applied by aircraft at operational levels on honeybees and its residues, if any, in 122 honeybee, pollen, beeswax and honey samples collected from sprayed forest areas in the provinces of Ontario and Quebec.

Plantation Research: XII. Experimental Applications of Insecticides by Mistblower for Control of Choristoneura fumiferana on White Spruce in Quebec, 1974

Problem Addressed: Spruce Budworm
Key Findings: Applications of commercial preparations of Bacillus thuringiensis at up to 8 BIU per acre did not provide significant levels of foliage protection when timed against peak third-instar larvae.

Final Report on The Effects of Forest Spraying on Reproduction in Smallmouth Bass Populations in Washington County

Problem Addressed: Smallmouth bass waters lie within the proposed spray area for operational control of spruce budworm
Key Findings: No direct fish mortality or physiological and behavioral responses were observed because of the doses used, the low toxicity, and the avoidance of direct application in the lake.

Strategic Chemicals for Protection of Coniferous Forests from insect Pests

Problem Addressed: Pests that are destructive to coniferous forests.
Key Findings: Fenitrothion is the no. 1 strategic chemical, followed by phosphamidon and Matacil, for the protection of coniferous forests from defoliating insects, taking into consideration efficacy against the target insects, safety to the other components of the forest ecosystem, economics, availability, adaptability to various formulations and modes of application

The Biological Side-Effects of Fenitrothion in Forests Ecosystems

Problem Addressed: Fenitrothion was both efficacious against spruce budworm larvae and of low hazard to fish and wildlife compared with its predecessors and with compounds available currently
Key Findings: Fenitrothion presents only negligible environmental impact if used as directed

The Effect of an Experimental Application of Dimiln Upon Selected Forest Fauna

Key Findings: No immediate or short term effects of Dimilin treatment on small forest songbirds or colonies of domestic honey bees. Small mammal populations in the treatment area were too low to assess insecticide impact. Further studies of the short and long term effects of this compound on non-target organisms are recommended, particularly with respect to components of aquatic ecosystems.
Recommendation: Further field and laboratory testing of the effects of Dimilin on non-target organisms

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 Review of Studies in Maine on the Impact of Aerial Applications of Sevin-4-oil on the Macroinvertebrate Fauna of Streams and Ponds

Problem Addressed: Effects of Sevin-4-oil
Key Findings: Evidence of a relatively severe impact on the fauna and persistence of residues in the sediment indicate that ponds as well as streams should be included in future monitoring programs
