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

Aerial Photographic Techniques for Assessing the Impact of Spruce Budworm Defoliation in Maine

Goal(s)/Objective(s): Development of remote sensing techniques to better evaluate current feeding, tree and forest condition from past feeding, forest recovery after spraying, and mortality location from spruce budworm defoliation and other causes.
Key Findings: Tree and forest stand condition from past feeding was best interpreted on the CIR fall photos at scales of 1320 ft/in and larger

Determination of Fenitrothion Residues in Honeybees and Their Products

Goal(s)/Objective(s): Describe the development of a gas-liquid chromatographic (GLC) method of analysis of the parent insecticide, its oxon and the cresol hydolysis product in honeybees (Apis mellifera L.) pollen, beeswax and honey from forested areas which had been treated with fenitrothion applied by aircraft.
Key Findings: Average recovery for the insecticide ranged from 84% in bees to 93% in honey.

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.
