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

Silviculture and the Spruce Budworm in Maine

Problem Addressed: Spruce Budworm
Key Findings: Fir, the primary host of the budworm, is here to stay and while we may reduce its representation in our stands, it will always be sufficient to provide a food source for the budworm; silvicultural practices may reduce the losses from budworm attack, and can reduce the impact of the budworm on our total production by promoting rapid growth in new stands.

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.
