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.
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.
