An Update On Rozol For Orchard Mouse Control, Sol Pitchon Feb 1978

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 …


The Hudson Valley's Experience Securing Endrin For Use In 1977, Warren H. Smith Feb 1978

The Hudson Valley's Experience Securing Endrin For Use In 1977, Warren H. Smith

Eastern Pine and Meadow Vole Symposia

The year 1977 was eventful for Hudson Valley fruit growers who are troubled by pine voles. In March when the snows melted it was clearly evident that serious vole damage to area orchards had taken place and immediate action was necessary to eradicate this menace. Cooperative Extension played a major leadership role organizing grower committee activities, and the North Eastern Fruit Council, a newly formed grower group, represented the industry during these activities. Steve Clark, a Milton, New York fruit grower, was chosen as chairman of the North Eastern Fruit Council grower action committee.


A Grower's Experience In Pine Mice Control - 1973 Through 1977, Philip Glaize Feb 1978

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.

Recent Vole Research In New York's Hudson Valley, Jonathan Bart, Milo E. Richmond

Eastern Pine and Meadow Vole Symposia

During fall, 1977, four potential chemical methods for controlling pine voles (Pitymys pinetorum) were evaluated on 12, one hectare plots in three apple orchards in the lower Hudson River valley. Each plot consisted of 45 trees. Three plots were treated with endrin, applied at the recommended rate of 1.5 lbs. per acre; two were treated with 2% technical Vacor (RH 787), applied in an unpelletized meal formulation at a rate of 60-70 gms per tree; two received 10% Vacor in an egg-sugar mix (marketed for human consumption as "Marshmallow Fluff") applied at the rate of 5-10 grams per …


Reproductive Patterns In The Pine Vole, Margaret Horsfall Schadler Feb 1978

Reproductive Patterns In The Pine Vole, Margaret Horsfall Schadler

Eastern Pine and Meadow Vole Symposia

Reproductive potential in the pine vole is low compared with other small rodents including other species of voles. Age of maturity is late. Males do not reach puberty before 51 days and females before 77 days. Estrus and ovulation are not spontaneous but tend to be induced by mature males. Gestation is long (24 days). Litter sizes are small (2.8 young weaned per female). Litters are produced less frequently because, although females mate and conceive within 3 days of parturition, prolonged gestation insures a minimum of 24-27 days between litters. Only dominant females in a group carry litters to term …

Status Of Pp581 (Volak) Rodenticide Development, Dale E. Kaukeinen Feb 1978

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 Extension Trapper Program, Jerry Riedel Dec 1977

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 …

Trapper Education And Furbearer Management, Edward K. Boggess Dec 1977

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 Dec 1977

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).

Usda Research On Impacts Of Predation, Russell L. Gum, Richard S. Magleby

Great Plains Wildlife Damage Control Workshop Proceedings

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?


The Effects Of Coyote Control Operations On Non-Target Species In New Mexico, Gary Lee Nunley Dec 1977

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.

The project is directed from Denver, with several biologists and technicians at field stations located in Twin Falls, Idaho; Uvalde, Texas; and Rawlins, Wyoming, as well as in Denver. This is a brief summary of our efforts during the past 12 months and should be considered an informal progress report.


A Mammalogist's View Of Current Mammal Damage Control Trends, Sydney Anderson Dec 1977

A Mammalogist's View Of Current Mammal Damage Control Trends, Sydney Anderson

Great Plains Wildlife Damage Control Workshop Proceedings

Different mammalogists have different views on this subject. The following are mine. Historically, there was considerable controversy in the American Society of Mammalogists around 1930 on the question of predator control. The primary reasons for these different views, then and also now, are different value judgements. Science without non-scientific value judgements is not sufficient to lead one to a single view or set of views. Science embodies certain value judgments such as honesty, the public value of human knowledge, objectivity, the desirability of formulating testable hypotheses, and the examination of all relevant and available evidence. Scientists are human beings and …


Predation On Furbearers And Management Alternatives, Ronald D. Andrews Dec 1977

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 …

Youth Fur Harvest Programs, Edward K. Boggess Dec 1977

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 …


Aspects Of Reproduction And Population Dynamics Of Bobcats In Wyoming, Douglas M. Crowe Dec 1977

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 …

Coydogs In Nebraska, Brian R. Mahan Dec 1977

Coydogs In Nebraska, Brian R. Mahan

Great Plains Wildlife Damage Control Workshop Proceedings

Skulls of 44 suspected coyote (Canis latrans) x dog (C. familiaris) hybrids, "coydogs" were collected in Nebraska from September 1975 through April 1976. Each skull was compared statistically with skulls of known coyotes, dogs, coydogs, gray wolves (C. lupus), and red wolves (C. rufus) for identification. Thirty-two males were identified as: 5 coyotes, 2 dogs, 25 coydogs; 12 females were identified as: 4 coyotes, 2 dogs, 6 coydogs. Three concentrations of hybrids were located in southeastern Nebraska.
