Tb113: A Field Test Of Mating-Suppression Using The Spruce Budworm Sex Pheromone, J. B. Dimond, D. G. Mott, W. P. Kemp, J. H. Krall
Technical Bulletins
Spruce budworm sex pheromone was dispersed from aircraft over forest land in Maine in late June, 1980. A major goal was to sample pheromone concentrations in air to determine whether the formulation would provide the steady, sustained release of chemical believed required for interfering with the mating process of the moths. Since pheromone was going to be applied for purposes of analyses of air, we believed we should also study some behavioral effects on spruce budworm populations. The principal body of data involved the ability of male budworm moths to orient to point sources of pheromone in pheromone-treated and untreated …

Black flies have been long-time residents of Maine and cause extensive nuisance problems for people, domestic animals, and wildlife. The black fly problem has no simple solution because of the multitude of species present, the diverse and ecologically sensitive habitats in which they are found, and the problems inherent in measuring the extent of the damage they cause. To improve the understanding of the nature of the black fly problem, an inventory of black fly species and habitats was made throughout the state. Previous black fly surveys in Maine have been geographically limited. In the present survey, black flies were …
Tb90: The Effects Of Spraying With Sevin-4-Oil® On Insect Pollinators And Pollination In A Spruce-Fir Forest, E. R. Miliczky, E. A. Osgood
Tb90: The Effects Of Spraying With Sevin-4-Oil® On Insect Pollinators And Pollination In A Spruce-Fir Forest, E. R. Miliczky, E. A. Osgood
Technical Bulletins
The use of chemical insecticides is presently accepted as the most effective means of keeping damage by spruce budworm in Maine at an acceptable level. Unfortunately, broad-spectrum chemicals such as Sevin-4-oil® affect non-target organisms as well, and this can have serious consequences. The significance of these effects can only be determined by monitoring populations of non-target organisms and assessing the overall impact on the environment. This study was undertaken to determine the effects of operational spraying of carbaryl insecticide, Sevin-4-oil® on the abundance of insect pollinators in a spruce-fir forest.

Tb84: Controlling The Saratoga Spittlebug In Young Red Pine Plantations By Removal Of Alternate Hosts, J. P. Linnane, E. A. Osgood
Tb84: Controlling The Saratoga Spittlebug In Young Red Pine Plantations By Removal Of Alternate Hosts, J. P. Linnane, E. A. Osgood
Technical Bulletins
The Saratoga spittlebug, Aphrophora saratogensis (Fitch), is a major pest of young red pine (Pinus resinosa Ait. ) and jack pine (Pinus banksiana Lamb. ) plantations in the Lake States, Ontario, and more recently in the Northeast. Although insecticides are successful in controlling the Saratoga spittlebug, the biology of the insect raises the possibility of an alternative method of control. The spittlebug requires an alternate host to complete its nymphal development. The objective of this study was to investigate the feasibility of using herbicides to control nymphal host plants of the spittlebug in red pine plantations.
