Update Of Pine Vole Research At The Kearneysville Experiment Farm, Roger S. Young

Eastern Pine and Meadow Vole Symposia

As reported in the 1979 Proceedings of the Third Eastern Pine and Meadow Vole Symposium, an air and ground broadcast and hand placement in runs and mouse-ateria bait stations (tubes) experiment was started on December 5, 1978. Treatments were to apply brodifacoum (Volak) at 10. 0 lb. /A and diphacinone (Ramik-Brown) at 10. 0 lb. and 20. 0 lb. /A air broadcast and 10. 0 lb. /A ground broadcast and hand placement. The air broadcast treatments were not evenly distributed. Ground catch of the air broadcast of brodifacoum resulted in one portion of the treated area receiving 24% more toxicant. …

Current Research Related To Pine And Meadow Vole Damage Control, Mark H. Merson, Ross E. Byers

Eastern Pine and Meadow Vole Symposia

This paper will outline some of the research related to pine and meadow vole damage control which is currently underway at the Winchester Fruit Research Laboratory and outline some of the areas which we will be pursuing in the future. One question which must be answered whenever a chemical is used to control a pest organism is how that chemical is impacting non-target organisms. A study was initiated in the fall of 1979, with the objective of determining by use of radiotelemetry the fates of birds of prey in the vicinity of orchards treated with Brodifacoum, an anticoagulant rodenticide. A …

Field Evaluation Of Candidate Rodenticide, Milo E. Richmond, Pamela N. Miller

Eastern Pine and Meadow Vole Symposia

During autumn of 1978 and 1979 the New York Cooperative Wildlife Research Unit continued its program of research and management aimed at the pine vole (Pitymys pinetorum) and meadow vole (Microtus pennsylvanicus). Two herbicides, Ammate-X (E.I. Dupont de Nemours) and Kerb (Rhom S Haas Corp.) along with 4 candidate rodenticides, Bromadiolone and Chlorophacinone (Chempar Inc.), Volak (I.C.I. Chemicals Inc.) and zinc phosphide (Bell Laboratories Inc.) were tested in both orchard and laboratory situations. This work is being conducted in conjunction with a separate research unit project aimed at evaluating the potential of using populations of the …

Rodenticide Use In Apple Orchards, Walter L. Ferguson

Eastern Pine and Meadow Vole Symposia

The preliminary data presented in this paper were obtained from the 1978 Survey of Pesticide Use on Deciduous Fruits (Figure 1). The survey was conducted by the Economics, Statistics and Cooperatives Service, USDA.

The purpose of this paper is to present information on: (1) rodenticides used in controlling meadow and pine voles, (2) method and timing of applications and type of coverage, (3) tree losses due to vole injury by region, and (4) growers perceived efficacy of chemicals versus cultural and mechanical controls. These data are based on the aggregated responses of the surveyed apple producers.

Disposition Of The Endrin Rpar, Lawrence S. Ebner, Harvey S. Gold

Eastern Pine and Meadow Vole Symposia

Following a comprehensive three-year Rebuttable Presumption Against Registration ("RPAR") review of endrin, on July 25, 1979 the U.S. Environmental Protection Agency announced its decision to continue federal approval of endrin for control of pine voles in the East and meadow voles in the West among other uses. See 44 Fed. Reg. 43,637-8. The Agency concluded that with additional safety precautions and procedures, endrin can be applied safely and effectively, and that the benefits of usage outweigh any risks. The stringent new safe¬guards being required by EPA, including new usage restrictions and directions, equipment specifications, and warnings to female applicators, are …

Movement Types And Weather Correlates In Free-Ranging Meadow Voles, Dale M. Madison

Eastern Pine and Meadow Vole Symposia

Meadow voles (Microtus pennsylvanicus) were radiotracked in their natural environment from June through August 1974, 1975 and 1978. Four different types of movement were observed: residency, shifting, wandering and dispersal. Next to the residency pattern, wandering was the most common form of movement and probably was important during breeding activities. Dispersal was a rare event and is probably confused with wandering in the existing literature.

A total of 17 weather variables were analyzed for correlations with vole movement. Male voles showed a distinct tendency to move more widely during periods of dry weather. The latter was attributed to …

Textural And Taste Influences On Gnawing By Pine Voles, Lynette A. Geyer, James N. Cummins

Eastern Pine and Meadow Vole Symposia

Pine voles and meadow voles exhibited differential preferences for various Malus clones. When damage to dormant stems in a 24-hr test was assessed by either a graded damage scale or percentage consumption by weight, pine voles preferred Golden Delicious, M.9, and M.26 and consistently avoided M.x sublobata PI 286613 ("613") and related clones and Robusta 5. Dehydrating stems magnified the disparity among cultivars, as attractive stems continued to suffer extensive damage, while 613 became even less palatable. In the autumn phase all varieties showed increased acceptance. Meadow voles, like pine voles, exhibited differential acceptance of cultivars, but their preferences differed …

Preliminary Field Observations Of Meadow Vole Preferences Among Selected Apple Clones, Karen Pearson, J. N. Cummins, John Barnard

Eastern Pine and Meadow Vole Symposia

Damage by voles has continued to be a major cause of tree mortality American orchards despite nearly universal use of herbicides and rodenticide. (1,7). To reduce damage done by voles in infested orchards, one valuable tool could be use of a stock system that voles found highly unattractive. Having such stock systems in place would be particularly valuable during periods when the orchardist could neither bait nor spray for control.

A cooperative VPI/Cornell research project initiated in 1974 identified a few cultivars with relatively high levels of resistance to pine voles, as expressed in free-choice tests under laboratory conditions. This …

Pine Vole Control In 1979 Field Plots, Ross E. Byers

Eastern Pine and Meadow Vole Symposia

Broadcast treatments of Volak (Brodifacoum) applied at rates of approx. 20 lbs/acre gave 98% control of voles when active ingredient levels were from 0.005% to 0.0005% in the bait. Of the two Rozol (Chlorophacinone)formulations tested, the French (Lipha) pelleted formulation appeared to be slightly better than what is currently being marketed in the USA. The Maki (Bromodialone) bait formulated in the same wax bait carrier as the Rozol-USA gave no better control than Rozol. Ramik-Brown (Diphacinone) did not appear to be as good as the other anticoagulants tested when applied either as a broad¬cast or as a hand placed bait. …

Effective Vole Control With Zp Rodent Bait Ag, Edward F. Marshall

Eastern Pine and Meadow Vole Symposia

Since the loss of DDT, Vacor (DPL 787) and other acute rodenticides and the serious use restrictions placed upon strychnine and 1080 for field use, it has become quite apparent that control of field rodents, more particular pine and meadow voles, with standard anticoagulants has become a difficult task, and in some instances impossible.

Bell Laboratories, Inc. has chosen to take a very serious look at many of the older compounds and rework and reformulate these compounds into palatable and efficacious finished baits. After 5 years of research and development. Bell Laboratories, Inc. has recently registered, with the Environmental Protection …

Management Model For Pine Voles: Preliminary Report, John F. Coyle, Alan R. Tipton

Eastern Pine and Meadow Vole Symposia

The use of computer models in scientific research has grown by leaps and bounds in the past decade. One of the primary reasons for this growth is the increased realization that computers and more specifically computer models, can be useful tools in synthe¬sizing large amounts of information and providing insight into problem areas of research and management.

Numerous books and papers have been written on the justification for modeling, the philosophy of modeling, and model development and utilization. Recent reviews of small mammal population models are given by Conley and Nichols (1978) and Stenseth (1977). This paper will not address …

An Environmental Study Of The Origin, Distribution, And Bioaccumulation Of Selenium In Kentucky And Barkley Lakes, B. E. Mcclellan, Kenneth J. Frazer

KWRRI Research Reports

Many samples of water, bottom sediment, and fish were analyzed for toxic metal ion content. The samples were collected from several selected sites along Kentucky and Barkley Lakes as well as the Cumberland River and several sub-impoundments along these aquatic systems. Emphasis was placed on selenium, although several other metal ions were determined. The results showed that there are no serious pollution problems with As, Cd, Cr, Cu, Hg, Pb, Se, Sr, Zn, or Zr at any of the sites examined. Actually, none of the trace metals examined even come close to the EPA limits on fish, with the exception …

A Comparative Water Quality Study Of Man-Made Drainage And Natural Streams, Kent W. Boyum

Journal of the Minnesota Academy of Science

The effects of man-made drainage systems on the water quality of receiving bodies Is relatively unknown. During the ice-free season of 1979, thirteen drainage ditches and f our rivers were sampled at intervals of three to eight days. With increasing flow, total orthophosphatephosphorous, total Kjeldahl-nitrogen, nitrate-nitrogen and total dissolved solids increased, but not proportionately to f low, with total orthophosphate-phosphorous showing the least proportionality. Variation was observed in each ditch and river when broken down seasonally for each parameter. Generally, when the percentage of flow was greater in one of the three seasons, the percentage of each of the other …

Oil And Gas Development On Georges Bank: The Responsibility Of Federal Agencies For Assessment And Mitigation Of Potential Impacts On The Ecosystem, Carolyn A. Griswold

Marine Affairs Theses and Major Papers

Is it possible to provide adequate protection for the Georges Bank ecosystem as oil and gas exploration begins? The fishing industry and environmentalists say "no," but it is the resource managers who are faced with the task of predicting, assessing and mitigating impacts of development while at the same time managing resources and protecting fishery habitats. Much of this responsibility falls within NOAA; however, legislative mandates and agency responsibilities and goals mean that several other federal agencies are involved as well. This paper is an attempt to describe the potential impacts of oil and gas exploration on the Georges Bank …

Toward Restructuring The Nova Scotia Fishing Fleets As A Result Of The Establishment Of Canada's 200-Mile Fishery Zone, Blaine Gillis

Marine Affairs Theses and Major Papers

The first step in redeveloping the Nova Scotia fishery is the restructuring and rebuilding of the various Nova Scotia commercial fishing fleets. In this paper, the evolution of the Nova Scotia fishery and fleets is outlined as background for discussion of concerns, issues, and conflicts of the various participants involved in determining the future structureand composition of the Nova Scotia fleet mix. It is concluded that whatsoever the structure and composition of the fleet, there remains the need to protect a critical balance among the various sectors of the Nova Scotia fishery.

Adaptative Alteration In Phospholipid Composition Of Plasma Membranes From A Somatic Cell Mutant Defective In The Regulation Of Cholesterol Biosynthesis, Michael Sinensky

Faculty Publications, Biological Sciences

A somatic cell mutant (CR1) of a Chinese hamster ovary cell (CHO-K1) which has previously been shown to be defective in the regulation of cholesterol biosynthesis accumulates more cholesterol than the parental cell line in plasma membranes. Although such an increase in membrane cholesterol should lead to an increase in the order parameter of these membranes, as measured with an electron spin resonance spin probe, the order parameters of mutant and wild-type plasma membranes are identical--apparently because of an adaptive alteration in membrane phospholipid composition. The phospholipid compositions of mutant and wild-type cell plasma membranes are compared and the mutant …
