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.
Tb129: Chemical Control Of Balsam Gall Midge Paradiplosis Tumifex Gagne (Diptera: Cecidomyiidae), R. L. Bradbury, E. A. Osgood
Tb129: Chemical Control Of Balsam Gall Midge Paradiplosis Tumifex Gagne (Diptera: Cecidomyiidae), R. L. Bradbury, E. A. Osgood
Technical Bulletins
This study was undertaken to test new insecticides for control of the balsam gall midge and to determine effectiveness of later insecticide application in order to expand the effective period for control.
Tb124: Chemical Control Of Balsam Twig Aphid, Midarus Abietinus Koch (Homoptera: Aphididae), R. L. Bradbury, E. A. Osgood
Tb124: Chemical Control Of Balsam Twig Aphid, Midarus Abietinus Koch (Homoptera: Aphididae), R. L. Bradbury, E. A. Osgood
Technical Bulletins
This study was initiated to provide Christmas tree growers with a selection of insecticides capable of effective control of balsam twig aphid (Mindarus abietinus Koch) on balsam fir. Low rates of active ingredients were tested to assure minimal environmental impact and reduced chemical costs
