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

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 …

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. …

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 …

HIGHLIGHTS OF THE FOURTH EASTERN PINE AND MEADOW VOLE SYMPOSIUM
The Fourth Eastern Pine and Meadow Vole Symposium was held in Hendersonvi1le, North Carolina February 21 and 22, 1980 for the primary purpose of assessing the current status of research and extension pro¬grams relating to the problem of vole damage to fruit trees. The meeting was designed to be informative and to create an atmosphere whereby growers and various agencies such as EPA, USDA, USDI, the chemical industry and university personnel could observe the current thrust of vole research programs and their potential impact on future control methods. …

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 Experimental Monitoring And Advisory Service In Orchard Vole Control, Don W. Hayne, William T. Sullivan Jr.
Eastern Pine and Meadow Vole Symposia
The North Carolina integrated, pest and. orchard, management project (IPOMS) has moved, from the data-gathering phase into an experimental information delivery system. We present here for possible comment the •written directions for vole monitoring that we prepared, for use by the orchard, specialists who will implement the monitoring and advisory system.
IPOMS started, in 1976 as a joint effort of a number of subject matter departments under the North Carolina Agricultural Research Service. A brief description of this cooperative effort of horticulturists, entomologists, plant pathologists, economists, zoologists and soil and weed. scientists has been presented to this group (Hayne 1978). …

The Status Of The Endrin Rpar, Kyle R. Barbehenn
Eastern Pine and Meadow Vole Symposia
The Agency's "Preliminary Determination" published in the Federal Register on November 2, 1978 proposed that the use of endrin to control voles in apple orchards be continued providing that several modifications in the label be made. What I would like to discuss briefly are (1) some of the bases for the decision, (2), one of the new requirements, and (3) comments received from the Office of Endangered Species, U.S. Fish and Wildlife service.

The Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) has recently been amended by the passage of The Federal Pesticide Act of 1978 (Public Law 95-396, passed September 30, 1978). While many aspects of the FIFRA have been amended, the changes of most immediate relevance to those interested in developing data in support of products used in the control of orchard voles are the authorities given the EPA Administrator to grant conditional registrations and to waive efficacy data requirements.

The Vole Control Program That Is Too Expensive, John E. Crumpacker
Eastern Pine and Meadow Vole Symposia
We have had some success for the past two years in controlling voles on a commercial scale at our orchards in Virginia. For years, vole control would vary from not acceptable to marginal control using various cultural methods and using ground sprays, such as Endrin and Chlorophacinone.

Eastern Pine and Meadow Vole Symposia
In the fall of 1977, New York fruit growers in the state's Hudson Valley region were given a temporary permit to use endrin in an effort to curb an increasing vole damage problem. The approval of endrin for this use was the first such large scale release of a chemical in this class since the banning in 1971 of most chlorinated hydrocarbons in this state. With approval for limited use came the obligation to monitor the Hudson Valley region for 1) efficacy of the material, 2) non-target effects on aquatic and terrestrial wildlife and 3) persistence in the orchard environment. …

Results Of Pine Vole Control Studies In 1978, Ross E. Byers
Eastern Pine and Meadow Vole Symposia
Broadcast treatments of a number of anticoagulant baits were found to be effective for the control of pine voles in orchards. Rates necessary for good control were: Volak - 15 lbs/A; Bromodiolone 15 lbs/A; Rozol - 20 lbs/A; two applications of Ramik-Brown - 20 lbs/A each. At least 3 days of good weather appeared to be required for good vole control. Cellophane packeted baits of Volak placed at each tree in vole runways under cinder blocks gave excellent control. Bait remained in excellent condition for long periods of time or until opened by voles. An electromagnetic device was evaluated for …
Impact Of Spacing Behavior And Predation On Population Growth In Meadow Voles, Dale M. Madison
Impact Of Spacing Behavior And Predation On Population Growth In Meadow Voles, Dale M. Madison
Eastern Pine and Meadow Vole Symposia
Free-ranging, sexually mature meadow voles (Microtus pennsylvanicus) were tracked using radiotelemetry from June through August 1974, 1975 and 1978. Up to 20 voles were monitored concurrently to derive estimates of intraspecific spacing and natural predation in an effort to clarify processes involved in the limitation of population growth. The daily ranges of the males, as compared to those of the females, were larger, more variable in size, and changed location more from one day to the next. Adult females usually maintained territories free of other females; males overlapped considerably among themselves. Males temporarily moved into the areas occupied by estrous …

Embryo Rejection In The Pine Vole, Kenneth J. Marks, Margaret Horsfall Schadler
Eastern Pine and Meadow Vole Symposia
When a pregnant pine vole is placed in a cage with a strange (unfamiliar) male, one that did not cause her pregnancy, this female goes into "heat", indicating she has rejected the embryos she was carrying. This pine vole can later be impregnated by the strange, or second male. This phenomenon of pregnancy termination, called the "Bruce effect", was first noticed by Hilda Bruce, who saw it occur in labratory mice. Many investigators have noted it in a variety of labratory mice, deer mice, and other species of voles. We set out to see if the Bruce effect was reproducible …

Vole Management Studies-1978, Jay Mcaninch
Eastern Pine and Meadow Vole Symposia
Earlier studies at the Cary Arboretum (McAninch, 1978) have described mowing and general cultural management practices as key elements in vole management programs. During the 1978 growing season, studies were initiated to quantify several soil parameters and vegetative elements in fruit orchards and correlate these characteristics to the distribution and abundance of vole populations. Although a great deal of additional orchard-vole data has been generated, only the associations described above will be discussed in this paper.

Eastern Pine and Meadow Vole Symposia
Because of the lack of long-term studies on the population dynamics of pine voles in Pennsylvania orchards, a study intended to collect various population parameters was initiated in Adams County in November 1973 and continued until November 1977. Two orchards, 0.3 km apart, were chosen for study. Pine voles in Orchard A were live-trapped, and those in Orchard B were snap-trapped. Population density estimates were determined from capture-recapture data from Orchard A, and information on age structure, reproduction, and physical condition were recorded from necropsied voles from Orchard B. Both orchards were maintained and treated by orchard personnel with Endrin …
Cost Of Controlling Pine Voles By Different Methods, William T. Sullivan Jr.
Cost Of Controlling Pine Voles By Different Methods, William T. Sullivan Jr.
Eastern Pine and Meadow Vole Symposia
A question often raised by apple growers, researchers, and agencies is "What does it cost on a per-acre basis to control pine and meadow voles?". In most cases this question refers to the methods and techniques presently known. At the Second Pine and Meadow Vole Symposium we described a new long-term study (Sullivan and Hayne 1978). This study provides answers to some of these basic cost questions. This year I am presenting some cost figures for the 1977 and 1978 seasons, recorded in treating the orchards in the study described at Beltsville. The efficacy of the treatments in controlling voles …

An experiment was established to evaluate the following methods of toxicant application: 1. A 25 ft. band broadcast ground application with Lely Spreader. 2. A 25 ft. band broadcast aircraft application with Grumman Ag-Cat. 3. Hand placement in runways. 4. Hand placement in plastic tube bait stations (' Mouse-ateria'). The following toxicants and application rates were desired: 1. Brodifacoum (Volak) applied at 10.0 lb./A. 2. Diphacinone (Ramik-Brown) applied at 10.0 lb. and 20.0 lb./A broadcast and 10.0 lb./A hand placement with one repeat application.

In July, 1976 the U.S. Environmental Protection Agency issued a "Notice of Rebuttable Presumption Against Registration and Continued Registration of Pesticide Products Containing Endrin" (41 Fed. Reg. 31,316). The purpose of this Notice was to initiate an "RPAR" review to determine whether continued usage of endrin, including the use of endrin for vole control, poses a "substantial question of safety" necessitating cancellation proceedings under Section 6(b) of the Federal Insecticide, Fungicide and Rodenticide Act ("FIFRA").
Behavioral Responses Of Pine Vole Young And Adults To Olfactory Cues, Lynette A. Geyer
Behavioral Responses Of Pine Vole Young And Adults To Olfactory Cues, Lynette A. Geyer
Eastern Pine and Meadow Vole Symposia
Ultrasonic vocalization rates of young pine voles are highest when pups begin to move into and out of nests and exhibit olfactory directed movement. As olfactory preferences become established and movement is coordinated, a decline in vocalization appears in pine vole. In the presence of home shavings young pine voles emit high rates of vocalization, while rat pups emit calls at a low rate. This contrast may relate to the intensive attachment of young pine voles to the mother in early life. In preliminary studies of adults, priming either the male or female with the odor of a prospective social …

The Third Eastern Pine and Meadow Vole Symposium was held in New Paltz, New York, February 14-15, 1979 to further create an awareness of the fruit growers' serious tree girdling problem. The meeting served to focus attention on a diversity of information on animal biology, control strategies and information dispensing mechanisms. Research funding sources, chemical and cultural control methods, clearance of new materials, and governmental involvement in pine vole problems were discussed.

At last year's meeting in Beltsville, William T. Sullivan, Jr., read a paper describing an experiment we had set up to compare vole control methods (Sullivan and Hayne 1978). In particular, this investigation attempts to measure the effect of clean orchard culture. This year I am describing some of our experiences with this experiment, with a preliminary appraisal of the different methods of study. Obviously, our observations must be accepted as very tentative, made as they are so early in the experiment.

Progress Report To The Second Pine Mouse Symposium On Control Measures By New York Growers, Steve Clark
Eastern Pine and Meadow Vole Symposia
In the past year, The Pine Mouse Action Committee of the North Eastern Fruit Council, mounted a successful campaign to secure a state label for endrin. This was a temporary state label for special use in pine vole infested orchards. Warren Smith, Extension Agent, will explain in more detail how this was done and what restrictions were imposed. To most of you, this may not seem like we made much progress, but this is the first time a persistent chemical has been returned to the active list. We feel the endrin will give us the needed vole control in orchards …
