Mp: 766 Roadside Rights-Of-Way As Pollinator Habitat: A Literature Review, Brianne Du Clos
Miscellaneous Publications
Pollination of crops and naturally-occurring flowering plants is a critical ecosystem service provided by managed and unmanaged animal pollinators. Insects are the most studied pollinators, particularly managed honey bees, unmanaged wild bees, and butterflies. Bees and butterflies thrive in early-successional habitat featuring grasses, exposed soil, wildflowers, and shrubs, which is consistently found within transportation and utility rights-of-way (ROW). However, intensive management of ROW can reduce the amount of high-quality pollinator habitat; such practices include frequent mowing, broadcast herbicide use, and planting non-native cool season grasses. Here, we review peer-reviewed academic and non-peer reviewed gray literature describing ROW management practices and …

Miscellaneous Reports
Bees are crucial to pollination in unmanaged ecosystems and some crops, and their roles are increasingly understood in four states in the Northeastern U.S., abbreviated “NNE” in this paper: Maine (ME), Massachusetts (MA), New Hampshire (NH), and Vermont (VT). The four states have in common many native bee and plant species, forest types, and natural communities. They share drought events and risk of wildfire (Irland 2013). They are exposed to many of the same major storms (e.g., hurricanes, Foster 1988), pollution events (Hand et al. 2014), and effects ascribed to climate change (Hayhoe et al. 2008). Beekeeping enterprises (the western …

Technical Bulletins
Bioblitzes have become a popular approach to involve scientists and the public in studying biodiversity. They reinforce the idea that natural areas are resources of scientific and educational value and are a way of engaging the public in experiencing the natural world. A bioblitz is typically conducted over a 24-hour period in a targeted area, with the goal of documenting the presence of as many species as possible. Scientists and “weekend naturalists,” along with other individuals who enjoy being in the field, are asked to attend bioblitzes as volunteers to help in finding and identifying as many species as possible. …

Tb199: Ant–Homopteran Relationships: Relevance To An Ant Invasion In Maine, Katherine E. Mcphee, Eleanor Groden, Francis A. Drummond
Technical Bulletins
The richness and diversity of native ant species on Mt. Desert Island, Maine, have been reduced in areas infested with Myrica rubra (European red ant). In general, the success of invasive ant species has been attributed to interference and exploitative competition coupled with the ants’ opportunistic diets. In field experiments on Mount Desert Island, Maine, M. rubra discovered and recruited to baits faster than native ants. This study also showed that M. rubra displaced most native ant species from food resources (Garnas 2005). This, together with M. rubra’s aggressive defense of invaded territories, has led to fewer native ants in …

Tb191: Conservation And Management Of Native Bees In Cranberry, Jennifer L. Loose, Francis A. Drummond, Constance Stubbs, Stephen Woods
Technical Bulletins
Threats to agriculturally important pollinators have serious implications for human beings. A loss of bees translates to less successful crop pollination, thus reduced yield and poorer quality fruits. Native bees have the potential to serve as commercial pollinators. A diverse pollinator complex comprised of both honey bees and native bees should result in stable pollination levels and should be resistant to threats such as disease, fluctuating honey and crop prices, and honey bee transportation costs. Adding the goal of native bee conservation to land management increases the ecological integrity of an ecosystem by conserving a unique biological interaction that is …

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 …

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 …
