Tb151: The Balsam Gall Midge--An Economic Pest Of Balsam Fir Christmas Trees, E. A. Osgood, R. L. Bradbury, F. A. Drummond
Tb151: The Balsam Gall Midge--An Economic Pest Of Balsam Fir Christmas Trees, E. A. Osgood, R. L. Bradbury, F. A. Drummond
Technical Bulletins
This technical bulletin summarizes all previous published research on the balsam gall midge. Also included are new data on the effect of late bud burst on midge oviposition and the degree of population regulation of the gallmaker by its inquiline.
Tb149: Wood Property-Age Relationships Of Natural And Plantation-Grown Red Pine, Robert K. Shepard, James E. Shottafer
Tb149: Wood Property-Age Relationships Of Natural And Plantation-Grown Red Pine, Robert K. Shepard, James E. Shottafer
Technical Bulletins
This study examined changes in specific gravity, modulus of rupture, and modulus of elasticity with age for a natural stand and two plantations. It also examined differences in wood properties between the three stands and the effects of important variables on, and their interactions with, wood properties. Wood property data were obtained from microbending specimens selected at breast height from five trees in each stand.

Mp716: New Forestry In Eastern Spruce-Fir Forests: Principles And Applications To Maine, Robert S. Seymour, Malcolm L. Hunter Jr.
Miscellaneous Publications
Eastern North America's spruce-fir forests have a unique ecological and human history which is reflected in their current vegetation, ownership patterns, and forest management practices. Furthermore, there are important differences within the region between the true boreal forest and the sub-boreal Acadian forest; this paper emphasizes the Acadian forest. Applying New Forestry to this region will require a modified approach which we outline by describing three basic principles. First, to provide the landscape context for New Forestry, we propose a triad of forest land allocation in which reserves and plantations would co-exist, surrounded by and embedded within a landscape managed …
Tb141: Nitrogen Fertilization Effects On Growth And Value Of Eastern White Pine Sawlog Stands On Till And Outwash Soils, Robert K. Shepard, Gregory A. Reams
Tb141: Nitrogen Fertilization Effects On Growth And Value Of Eastern White Pine Sawlog Stands On Till And Outwash Soils, Robert K. Shepard, Gregory A. Reams
Technical Bulletins
Diameter growth response functions were developed using data collected from nitrogen fertilization study plots in eastern white pine stands on till and outwash soils. These functions were combined with height measurements and used to evaluate stand volume and value growth. White pine diameter growth functions were developed for application rates of 0, 50, 100, and 200 lb of nitrogen/ac, but only those for the 0 and 100 lb/ac treatments were compared because it was evident that the 100 lb/ac treatment would provide a larger financial return than either 50 or 200 lb/ac. The mean increase in sawtimber volume due to …
B837: New Approaches To Chemical Control Of White Pine Weevil Damage, John B. Dimond, Richard L. Bradbury
B837: New Approaches To Chemical Control Of White Pine Weevil Damage, John B. Dimond, Richard L. Bradbury
Bulletins
There has been little recent research on control of damage by the white pine weevil, and available insecticides have been few and have become obsolete. Tests in Canada suggested that the insect growth-regulating chemical diflubenzeron was effective, and we have successfully repeated those tests in Maine using several formulations of Dimilin and several ground application systems. Aerial trials have not succeeded; the probable reasons for their failure are discussed. We present a general description of the weevil and its damage, approaches to control of damage, and specific recommendations for use of ground applications of Dimilin, which has recently become registered …
Tb148: Alternative Forage Plants For Native (Wild) Bees Associated With Lowbush Blueberry, Vaccinium Spp., In Maine, C. S. Stubbs, H. A. Jacobson, E. A. Osgood, F. A. Drummond
Tb148: Alternative Forage Plants For Native (Wild) Bees Associated With Lowbush Blueberry, Vaccinium Spp., In Maine, C. S. Stubbs, H. A. Jacobson, E. A. Osgood, F. A. Drummond
Technical Bulletins
To determine potentially suitable alternative food sources for important native bee pollinators of blueberry, the primary objectives of the present research were (1) to compile the published North American nectar, pollen, and flower records; (2) to analyze the pollen loads of native bees associated with Vaccinium spp. in Maine; and (3) to survey distribution and abundance patterns of native bee populations in Maine blueberry fields.
