A Grower's View Of Vole Control Methods, R. N. Barber
A Grower's View Of Vole Control Methods, R. N. Barber
Eastern Pine and Meadow Vole Symposia
Barber Orchards has been an operating orchard since 1903. Our number one problem as far as pests are concerned has been the loss of trees due to mice — pine and meadow vole.
In the 20's, 30’s, and 40's, we consistently lost from 300 to 500 trees per year, even though we were putting out and using every known conventional bait station and bait known to the various states growing apples in a commercial way. We used poisoned oats, wheat, chufers, peanuts and apples which we placed in the runs and holes, as well as under one yard squares of …
A Grower's Experience In Pine Mice Control - 1973 Through 1977, Philip Glaize
A Grower's Experience In Pine Mice Control - 1973 Through 1977, Philip Glaize
Eastern Pine and Meadow Vole Symposia
By 1973 Endrin in Virginia was pro-Ting ineffective. Mice were resistant to Endrin in Most orchards.
Dr. Horafall had started work with Chlorophaclone (C.P.N.) just prior to 1973 and Virginia had cleared it for experimental use.
In November we purchased a considerable amount of the first that was manufactured.
The first C.P.N. that was applied at the recommended rate of .2 lbs. per acre was very effective. The weather was fairly warm and according to our checks we had 90 percent control.
Unfortunately, part of our C.P.N. separated due to a bad formulation and we could not complete the job.
The Meadow, Prairie, And Pine Vole Problem In Ohio, Charles L. Mcgriff
The Meadow, Prairie, And Pine Vole Problem In Ohio, Charles L. Mcgriff
Eastern Pine and Meadow Vole Symposia
Fruit growers, nurserymen, and Christmas tree growers in Ohio suffer economic loss each year if tree-girdling mice are present and not con¬trolled. Unfortunately, in Ohio as elsewhere we have no practical method for arriving at the total value of loss from mouse damage. The grower's reports of losses are merely estimates.
Populations of meadow, prairie, and pine voles are present in Ohio, with pine voles most common in the Southern part. It is essential that the grower identify the species present, because control methods differ, and the same materials are not equally effective for all species.

HIGHLIGHTS OF THE SECOND EASTERN FINE AND MEADOW VOLE SYMPOSIUM
The Second Eastern Pine and Meadow Vole Symposium met at Beltsville, Maryland, February 23-24, 1978, to discuss various solutions to the serious damage caused by these rodents to fruit trees in the Eastern United States. Fruit growers, local, state, and federal research and extension specialists from many universities, Environmental Protection Agency, U. S. Department of Agriculture, U. S. Department of Interior, and the chemical industry participated in the program.
The purpose of the second symposium was to focus attention on one of the most serious cultural problems facing the fruit …
Pine Vole Control Studies In Virginia - 1977, Ross E. Byers
Pine Vole Control Studies In Virginia - 1977, Ross E. Byers
Eastern Pine and Meadow Vole Symposia
Hand placed baits of Rozol (Chlorophacinone, CPN), Ramik-Brown (Diphacinone, DPN), and Talon (Brodifacoum, BFC) gave excellent control of pine voles in 1977. Vacor (RH 787) did not give adequate control when a meal preparation was hand placed at 10 lbs/A.
Talon and Rozol broadcast at 25 and 22 lbs/A, respectively, gave 100% and 967. control of pine voles. Five lbs/A of hand placed Talon gave equivalent control. A second broadcast experiment of LM 637, Rozol and Talon at 15 lbs/A each was followed by rain the next day but gave 21%, 66%, and 93% control, respectively.

Status Of Pp581 (Volak) Rodenticide Development, Dale E. Kaukeinen
Eastern Pine and Meadow Vole Symposia
In the Proceedings of the first Eastern Pine and Meadow Vole Symposium (March 1977, Winchester VA), ICI was introduced and basic technical information on PP581 presented. PP581 is a second-generation anticoagulant rodenticide, with the approved common chemical name of brodifacoum. The compound is also known as TALON™ in the form of 50 ppm (0.005%) grain-base pelletized bait as developed for control of commensal rodents. The proposed trade name for the orchard formulation of PP581 is VOLAK™. Brodifacoum has been seen to possess several novel characteristics in work with commensal and other rodent species, suggesting a considerable general potential for control …
An Update On Rozol For Orchard Mouse Control, Sol Pitchon
An Update On Rozol For Orchard Mouse Control, Sol Pitchon
Eastern Pine and Meadow Vole Symposia
ROZOL- continues its advance in establishing itself as a reliable product for controlling orchard mice.
ROZOL GROUND SPRAY CONCENTRATE is still the only alternative to Endrin, not only from the persistence point of view, but for its effectiveness. Environmentally, ROZOL GROUND SPRAY CONCENTRATE is proving to be a desirable product because shortly after it controls the mice, it degrades into non-toxic metabolites, thus lacking the residue problems that exist with Endrin.
Furthermore, mouse resistance to Endrin has developed after many years of orchard use. Clear field data has established that ROZOL GROUND SPRAY CONCENTRATE is more effective than Endrin in …
Five Years Of Controlling Meadow And Pine Vole With Ramik Brown, J. G. Connell, W. B. O'Neal
Five Years Of Controlling Meadow And Pine Vole With Ramik Brown, J. G. Connell, W. B. O'Neal
Eastern Pine and Meadow Vole Symposia
Testing of Ramik for control of orchard mice was begun in 1972 in New York. By 1974 there were many test locations all over the Northeast, and by 1975 tests were conducted all over the country. Analyzing the results of some of the early testing suggested some refinements of application technique and formulation. These changes were made to better adapt Ramik to the conditions found in the orchard, and to make it more attractive to the voles. Some of the parameters examined are outlined below:
1. Bait flavor
2. Weather effects on the bait
3. Pellet size
4. Toxicant concentration …

Brief Summary Of Prebaiting Study For Prairie Dog Control, Ken Seyler
Brief Summary Of Prebaiting Study For Prairie Dog Control, Ken Seyler
Great Plains Wildlife Damage Control Workshop Proceedings
Attached are two tables summarizing data collected during a pre-baiting study for prairie dog control. The study was conducted in the Pryor, Montana area of Big Horn County, July 13-21, 1977, and in the Tongue River area of Custer County, Montana, August 24-September 3, 1977, and October 17-24, 1977. Applications of strychnine oats (Sebesta's .44%) and zinc phosphide oats (U.S. Fish and Wildlife Service, Pocatello Suppy Depot, 2%) with and without prebait (steamrolled oats) were compared for effectiveness in the control of prairie dogs.

Coyote And Dog Depredations, Joe Schaefer, Ronald D. Andrews
Coyote And Dog Depredations, Joe Schaefer, Ronald D. Andrews
Great Plains Wildlife Damage Control Workshop Proceedings
The objective of this study is to determine the impact of coyote and dog depredation on the sheep industry in southern Iowa and to evaluate the livestock husbandry practices associated with these losses. In order to obtain background information on sheep management practices and the number of alleged livestock losses caused by coyotes and dogs in southern Iowa, a questionnaire was sent to 3,173 sheep producers. Sixty-nine percent of the 1,260 respondents indicated that they did not have any problem with coyote depredations during 1975. However, the major cause of mortality was reported to have been coyote predation which accounted …

Predation On Furbearers And Management Alternatives, Ronald D. Andrews
Predation On Furbearers And Management Alternatives, Ronald D. Andrews
Great Plains Wildlife Damage Control Workshop Proceedings
Most of the presentations from other members of the panel have discussed direct predation of one animal upon another with evidence and data to support it. Their presentations indicate that in some instances, considerable data has been collected that substantiates the fact that predation has been and can be a limiting factor in sustaining certain local animal populations. Suggestions have also been made concerning management alternatives that might help to reduce this predatory impact when desirable. Predation on furbearers and its impact is considerably more ambiguous and abstract. Facts and data concerning significant predation on furbearers, except for mink on …
Aspects Of Reproduction And Population Dynamics Of Bobcats In Wyoming, Douglas M. Crowe
Aspects Of Reproduction And Population Dynamics Of Bobcats In Wyoming, Douglas M. Crowe
Great Plains Wildlife Damage Control Workshop Proceedings
Distribution of the bobcat includes the 48 contiguous United States and limited occupance of southern Canada and northern Mexico. There are 11 subspecies, the one in Wyoming being Lynx rufus pallescens. Bobcats inhabit an amazing variety of habitat types, from northern boreal forests, southern swamp, and cane regions to the below sea level desert of Death Valley, California. Throughout this vast area, they utilize a wide variety of prey species. One study in Wyoming revealed at least 18 different species in the stomachs of bobcats; the cottontail rabbit being predominant. A similar study in New England revealed 20 different …

Youth Fur Harvest Programs, Edward K. Boggess
Youth Fur Harvest Programs, Edward K. Boggess
Great Plains Wildlife Damage Control Workshop Proceedings
Youth fur harvest programs in Kansas have been developed as one phase of an overall series of youth education projects on ecology and the environment. Currently, the series includes Ecology, Acres for Wildlife, Kansas Mammals, Birds Around You, Reptiles and Amphibians, Fur Harvest, and Fishing. Basically, the fur harvester project was developed because, although many young people in the state are interested in trapping, few good sources of information or instruction were available to most young trappers. Because many objectionable trapping abuses are unintentionally caused by young or inexperienced trappers, it was hoped that this project would encourage ethical and …
Trapper Education And Furbearer Management, Edward K. Boggess
Trapper Education And Furbearer Management, Edward K. Boggess
Great Plains Wildlife Damage Control Workshop Proceedings
Modern concepts of furbearer harvest on a controlled, sustained-yield basis are in accordance with recognized principles of wildlife management and natural resource conservation. Steel traps, in the hands of private citizens and regulated by state fish and game agencies, have been the primary tools used in this country for managing furbearers. Fur resource managers recognize that traps are important tools not only in furbearer management, but also in some programs of wildlife damage or disease control. Traps also provide a major source of outdoor recreation for many people.

The Use Of Aversive Agents For Predator Control, M.P. Botkin
Great Plains Wildlife Damage Control Workshop Proceedings
The studies have continued in the search for potentially aversive compounds and mixtures. To date, undecenovanillylamide is the most effective substance found and is most effective in a mixture with p-dichlorobenzene. Three materials which have been tested actually appear to stimulate attack by coyotes on the treated animal. These are: Skatol (a fecal compound), Naphthalene and Thiomalic acid ( a foul sulpher-like odor).

This research by the U.S. Department of Agriculture, Economic Research Service, was done at the direct request of Congress, and with special funding in fiscal years 1974 and 1975. Basic questions guiding the research were: 1. How sizable are predation losses? How many producers are effected? 2. What effect has predation had on the decline of the sheep industry? 3. What are benefits and cost of predator control programs?
Skunk Rabies Control And Surveillance In Central And Eastern Montana, Gary Nesse, Kenneth Seyler
Skunk Rabies Control And Surveillance In Central And Eastern Montana, Gary Nesse, Kenneth Seyler
Great Plains Wildlife Damage Control Workshop Proceedings
A skunk rabies control and surveillance program was initiated by the Department of Livestock, Vertebrate Pest Control Bureau, within designated areas of Fergus, Fallon and Richland counties between January 1, 1975 and July 30, 1975. The use of strychnine eggs employed by trained, licensed government pesticide applicators plus cooperation of local citizens proved to be a safe and selective method for conducting such a program. Of the 83 skunks diagnosed rabid by the Fluroescent Antibody Test as the Department of Livestock Diagnostic Laboratory in Bozeman, 72 percent were taken from control areas; however, of 284 skunks examined from control areas, …

The Effects Of Coyote Control Operations On Non-Target Species In New Mexico, Gary Lee Nunley
Great Plains Wildlife Damage Control Workshop Proceedings
In February of 1972 the use of compound 1080, sodium cyanide, and strychnine in Federal coyote control programs and on Federal lands was halted as directed by Executive Order 11643. Shortly thereafter, the Environmental Protection Agency cancelled the registration of these same toxicants as used in predator control. These actions were taken at the recommendation of the Advisory Committee on Predator Control in their report to the Council of Environmental Quality and to the Department of the Interior.
An Extension Trapper Program, Jerry Riedel
An Extension Trapper Program, Jerry Riedel
Great Plains Wildlife Damage Control Workshop Proceedings
South Dakota's Extension Trapping Program originated in July 1971 when the Department of Game, Fish and Parks initiated this type of animal damage control program for the eastern one-half of South Dakota. The funding for this program is derived by assessing a surtax on all farmers and ranchers at a rate of 1 cent per head on all cattle and 4 cent per head on all sheep. The monies gained here is then annually matched by the Game, Fish and Parks through hunting, fishing and trapping license by the Game, Fish and Parks. However, for the last two years a …
