Lmmunocontraception In White-Tailed Deer, John W. Turner Jr., Jay F. Kirkpatrick, Irwin K.M. Liu

Contraception in Wildlife Management

lmmunocontraception may have management application for white-tailed deer populations in parks and preserves. where hunting 1s illegal or impractical. This study examines physiological aspects of immunocontraception with porcine zonae pellucidae in 53 fertile white-tailed does. In separate studies, we employed protocols of three and two porcine zonae pellucidae (PZP) injections as well as two different protocols using one injection. Each one-injection vaccination consisted of one dose of porcine zonae pellucidae as in other protocols plus a second controlled-release dose of the material delivered via an osmotic minipump implant or injected, biodegradable polymer microspheres. We monitored fawn production for 1 to …

Lmmunosterilization For Wild Rabbits: The Options, C.H. Tyndale-Biscoe

Contraception in Wildlife Management

Control of wildlife pest populations by sterilization could be more effective than conventional mortality agents, provided that two conditions are met: (1) the endocrine function of affected animals is not compromised, so as to exploit the natural suppression of reproduction of subordinate members of the population that occurs in many species; and (2) the incidence of sterility is sufficient to lower population recruitment and growth. Both conditions could, theoretically, be met by use of an infectious recombinant virus, expressing genes for specific reproductive antigens. Using the rabbit, I describe the research required to test the concept and discuss the legal …

Research And Field Applications Of Contraceptives In White-Tailed Deer, Feral Horses, And Mountain Goats, Robert J. Warren, Richard A. Fayrer-Hosken, Lisa I. Muller, L. Paige Willis, Robin B. Goodloe

Contraception in Wildlife Management

This paper reviews our applications of long-acting implantable steroids and immunocontraceptives in selected wild ungulates. We implanted captive white-tailed deer does with levonorgestrel but did not successfully prevent conception. We also evaluated antisperm immunocontraceptives delivered remotely via biobullet. Does immunized with plasma membrane proteins isolated from deer or porcine sperm showed persistence of antisperm antibody titers for 5 months, but these titers did not cause infertility. Our research also has included applications via biobullet or antigonadotropin-releasing hormone (GnRH), antisperm, and antiporcine zona pellucida (ZP) vaccines in female horses. Although the biobullet was effective in delivering immunocontraceptives at distances of ≤ …

Changes In Ovulation Rate, Uterine Capacity, Uterine Dimensions, And Parity Effects With Selection For Litter Size In Swine, Luis L. T. Gama, R. K. Johnson

Department of Animal Science: Faculty Publications

This study was conducted with random samples of pigs of a line (LS) selected for eight generations for litter size and a randomly selected control line (RS) in the Nebraska Gene Pool population and of crosses of these lines with a Large White- Landrace composite line (I) that was selected for an index of ovulation rate and embryonic survival to 50 d of gestation. Two experiments were done to obtain information on ovulation rate, uterine dimensions, and uterine capacity. In Exp. 1, 103 gilts were slaughtered 9 to 16 d after their second estrus to obtain reproductive tracts for evaluation …

Status And Management Of Vole Damage To Horticultural Plantings In North Carolina, Peter T. Bromley, William T. Sullivan Jr.

Eastern Wildlife Damage Control Conference: 6th (1993)

A trapping study in 1979 indicated that voles (Microtus pinetorum and M. pinetorum) were distributed widely in North Carolina. In 1991, Extension Agents with the North Carolina Cooperative Extension Service were surveyed to determine the distribution, nature and severity of vole damage to horticultural plantings, home orchards, and other plantings. Data from the statewide trapping survey and the poll of agents coincided to indicate that voles, particularly pine voles, caused damage from the mountains to the coast. Existing, legal control methods were judged grossly inadequate by agents. Pursuant to the surveys, the North Carolina Pesticide Board and the North Carolina …

Dispersal Of Ring-Billed Gull Nesting Colonies In New York State, James E. Forbes, Maury W. Bedford, William W. Beck, Brian V. Archuleta

Eastern Wildlife Damage Control Conference: 6th (1993)

Ring-billed gulls (Larus delawarenis) are adapting to rooftop nesting habitats throughout the Northeast and the Great Lake States. Presently, six such colonies exist in New York State. Noise, plus accumulations of droppings, feathers and nesting material, cause unsanitary conditions, structural damage, health problems, traffic problems and have lead to Occupational Safety and Health Administration citations. We began a 3-year project in 1991 at two locations, Niagara Falls and Syracuse, New York, to relocate nesting gulls to other nesting sites. Eight lethal and nonlethal control alternatives were considered and three nonlethal alternatives were selected. We concluded that: (1) the nonlethal techniques …

Propagation Of Bamboo As Blackbird Lure Roost Habitat, Richard D. Flynt, James F. Glahn

Eastern Wildlife Damage Control Conference: 6th (1993)

Bamboo and native cane species have been suggested as optimal lure roost habitat for shifting blackbird winter roosts away from objectionable urban/suburban sites. As the second phase in developing this potential concept of alleviating conflicts with blackbirds, we report on information gathered from the literature, consultations with bamboo horticulturists, and on-site visits to previously developed bamboo plantations to select desirable species of bamboo for this purpose, and to identify preferred propagating techniques. Bamboo species Phyllostachys rubromarginata and P. nigra henonis ranked highest in terms of greatest cold tolerance, greatest propensity for lateral spreading, and most suitable structure characteristics for maintaining …

Effects Of A Bird Hazard Reduction Force On Reducing Bird/Aircraft Strike Hazards At The Atlantic City International Airport, Nj, Andy J. Montoney, H. Christopher Boggs

Eastern Wildlife Damage Control Conference: 6th (1993)

Bird-aircraft strikes at the Atlantic City International Airport (ACY) increased from 18 in 1989 to 37 in 1990. The number of bird-aircraft strikes involving gulls (Larus spp.) during this time rose from 6 to 27, a 350% increase. The predominant species involved in bird strikes was the laughing gull (L. atricilla). Pursuant to an interagency agreement between the U.S. Department of Transportation (USDOT), Federal Aviation Administration (FAA) and the U.S. Department of Agriculture (USDA)l Animal and Plant Health Inspection Service (APHIS)/Animal Damage Control (ADC), ADC established a Emergency/Experimental Bird Hazard Reduction Force (BHFF) at ACY in 1991. An Environmental Assessment …

An Evaluation Of Floating Ropes For Reducing Cormorant Damage At Catfish Ponds, Donald F. Mott, Richard D. Flynt, Junior O. King

Eastern Wildlife Damage Control Conference: 6th (1993)

A floating rope system consisting of lengths of 9.5 mm (3/8 in) yellow polyethylene rope and foam floats was evaluated for reducing double-crested cormorant (Phalacrocorax auritus) depredation on farm raised channel catfish (Ictalurus punctatus) Mississippi. The ropes were placed at 15-17 m intervals across 2 ponds (4.6 and 6.0 ha) perpendicular to the prevailing winds. Helium-filled balloons were used in an attempt to enhance the effect of the ropes. Cormorant numbers entering both test ponds were recorded during pretreatment, treatment, and posttreatment periods. The floating ropes were effective in reducing cormorant numbers on ponds (by at least 95%) during the …

Evaluation Of Max-Flex Fast Fence(Tm) For Reducing Deer Damage To Crops, John T. Owen, James B. Armstrong, H. Lee Stribling, M. Keith Causey

Eastern Wildlife Damage Control Conference: 6th (1993)

A 2-year study was undertaken to assess the effectivenesS of Max-Flex Fast FenceTM electric fencing materials (polytape) for reducing damage to crops. Specifically, our goal was to look at the efficacy of this product for the borne gardener. In the first phase of the project, plots of approximately 1/40 acre were established in areas of historically high deer densitieS. Each plot was planted with soybeans and randomly assigned to 1 of 4 fencing configurations or to the open control group. Within each plot, 6' wide strips were tilled across the length. These tilled areas were checked for the presence of …

Status Of Alpha Chloralose And Other Immobilizing/Euthanizing Chemicals Within The Animal Damage Control Program, Paul P. Woronecki, William L. Thomas

Eastern Wildlife Damage Control Conference: 6th (1993)

In 1992 the U.S. Department of Agriculture (USDA), Animal and Plant Health Inspection Service, Animal Damage Control (ADC) program was granted approval from the U.S. Food and Drug Administration (FDA), under a continuing Investigational New Animal Drug agreement, to use Alpha-chloralose (A-C) nationwide for capturing nuisance waterfowl, coots, and pigeons. FDA and ADC have imposed several requirements, restrictions and conditions on the operational use of A-C. Training and certification are required to use A-C and other approved immobilizing and euthanizing agents.

Strategies To Address Human Conflicts With Raccoons And Black Bears In New Hampshire, Marsha E. Barden, Dennis Slate, Robert T. Calvert, Paul W. Debow

Eastern Wildlife Damage Control Conference: 6th (1993)

The Cooperative Animal Damage Control program in New Hampshire has received increasing requests for assistance over the past 5 years. This trend is due largely to changing public concern over black bears (Ursus americanus) in residential areas and an epizootic of the Mid-Atlantic strain of rabies in raccoons (Procyon lotor). A growing number of requests is related to improper garbage storage and feeding of songbirds during late spring and summer. Some traditional methods, especially livetrapping and relocation, are not generally appropriate to resolve these conflicts. In this paper we discuss trends in requests for assistance from 1988 to 1992 and …

A Survey Comparison Of Pest Control And Nuisance Wildlife Control Operators In Kentucky, Thomas G. Barns

Eastern Wildlife Damage Control Conference: 6th (1993)

A variety of factors including increased urbanization decreased funding for governmental animal damage programs, and increases in some urban wildlife populations have resulted in a greater demand for urban nuisance wildlife control. Historically, this demand was met by Cooperative Extension Service (San Julian 1987), state fish and wildlife agency, or federal wildlife damage control employees (Bollengier 1981) These agencies provided educational materials, consultations, an-or physically removed animals. Recently, there is an increased demand for physical animal removal evidenced by increasing numbers of private Pest control operators (PCO), companies that do general pest or insect control work, specializing in the removal …

Balancing The Needs Of Society: A Perspective For Wildlife Damage Management In The ’90s, Jack H. Berryman

Eastern Wildlife Damage Control Conference: 6th (1993)

This is a moment when the new direction of wildlife damage management, an increase in needs for services and an emerging philosophy of resource use all come together: It is important to seize the moment and keep the momentum going. We are at one of those times when circumstances and favorable conditions present both challenge and opportunity. Broadening the view of “balance” and “need” to go beyond material, ecological and economic considerations and to recognize the total public interest is the real need in “balancing the needs of society.” It is the challenge and opportunity for the future

The Role Of The Nuisance Wildlife Control Practitioner In Urban Wildlife Management And Conservation, Lynn A. Braband

Eastern Wildlife Damage Control Conference: 6th (1993)

Private sector involvement in nuisance wildlife control has evolved from primarily part-time trappers to full-time firms with their own professional organization, the National Urban Wildlife Management Organization (NUWMA). The private sector plays a key role in urban wildlife management by providing an effective service in addressing human/wildlife conflicts. This role can be improved and expanded by enabling nuisance control practitioners to provide accurate information on wildlife biology, damage prevention, and even wildlife habitat promotion. Both government agencies and private organizations, such as NUWMA, can facilitate this by developing appropriate training, regulations, licensing procedures, standards of ethics, and continuing education programs.

Similarities Between Big Game Repellent And Predator Urine Repellency To White-Tailed Deer: The Importance Of Sulfur And Fatty Acids, Rebecca Lewison, N. Jay Bean, Evgeny V. Aronov, John E. Mcconnell Jr., J. Russell Mason

Eastern Wildlife Damage Control Conference: 6th (1993)

In the present experiment, we evaluated the repellency of Big Game Repellent® (BGR), whole coyote urine, coyote urine with sulfur compounds removed, and water. Each stimulus was applied to an ornamental plant (hostas, Alba marginata) at 5 sites in the vicinity of Poughkeepsie, N.Y. At weekly intervals for 5 weeks, damage was recorded, treatments were reapplied, and plants were replaced when necessary. There was no damage to plants treated with either BGR or whole coyote urine. This was not true for plants sprayed with sulfur-free urine or water. We conclude that the repellency of coyote urine is largely a consequence …

Can We Landscape To Accommodate Deer? The Tracy Estate Research Garden, Helen H. Heinrich, Susan Predl

Eastern Wildlife Damage Control Conference: 6th (1993)

The Morris County Park Commission, manager of hundreds of acres of open space in this central New Jersey county, realized that the white-tailed deer residing on park land were having a detrimental effect on the vegetation on these properties. A Wildlife Management Advisory Committee to the Commission was formed to measure the dimensions of the problem and to find ways to mitigate the effects of the deer population of deer. One recommendation of the Committee was to determine if a landscape design could be developed to use plantings less attractive to the deer; planted in ways that might discourage heavy …

Predator Depredations On Sheep In Pennsylvania, Gary W. Witmer, Arnold Hayden, Michael Pipas

Eastern Wildlife Damage Control Conference: 6th (1993)

The eastern coyote (Canis latrans) has become common and widespread in many eastern states. We surveyed 331 sheep producers in Pennsylvania (PA); 22% reported predator losses in 1991, primarily to dogs and coyotes. Losses were heaviest in the southwest part of PA and producers reporting losses tended to have more sheep and more acreage in pasture. To reduce losses, producers used lambing sheds, fences, guard dogs and donkeys, confinement of sheep, trapping, and shooting. It appears that we can expect greater depredations in the future because of increased coyote numbers and a relatively low level of protection of sheep; however, …

Vegetative And Reproductive Biomass Accumulation In Field Corn: Response To Root Injury By Western Corn Rootworm (Coleoptera: Chrysomelidae), L. D. Godfrey, Lance J. Meinke, Robert J. Wright

Department of Entomology: Faculty Publications

A 2-yr field study was conducted to evaluate the effects of larval injury by western corn rootworm, Diabrotica virgifera virgifera LeConte, on vegetative and reproductive biomass accumulation of field corn, Zea mays L. Studies in 1989 were conducted in irrigated, silty clay loam soil, whereas in 1990, the possible interacting effects of soil texture (silty clay loam, loam, and sandy loam) and soil moisture (furrow-irrigated and dryland) were examined. In both years, during the early phases of injury (feeding by first and second instars), the vegetative biomass was detrimentally affected. Larval infestations reduced leaf area and leafwet weight by up …

Efficacy And Persistence Of Steinernema Carpocapsae (Rhabditida: Steinemematidae) Applied Through A Center-Pivot Irrigation System Against Larval Corn Rootworms (Coleoptera: Chrysomelidae), Robert J. Wright, J. F. Witkowski, G. Echtenkamp, R. Georgis

Department of Entomology: Faculty Publications

We evaluated control of natural and artificially infested populations of larval com rootworms (Diabrotica virgifera virgifera LeConte and D. barberi Smith & Lawrence) in corn (Zea mays L.) treated with entomopathogenic nematodes, Steinernema carpocapsae (Weiser); All strain, applied after planting through a center-pivot irrigation system at 2.5 and 1.2 x 10⁹ infective juvenile nematodes per hectare. We compared control achieved with nematodes with that achieved with planting time applications of terbufos (Counter 15G [granular]; 9.9 kg [AI]/ha) and chlorpyrifos (Lorsban 4E [emulsion]; 1.12 kg [AI]/ha) applied after planting through an irrigation system, and with an untreated (water …

Closure To "Darcy-Weisbach Roughness Coefficients For Gravel And Cobble Surface", John E. Gilley, Eugene R. Kottwitz, Gary A. Wieman

Department of Agricultural and Biological Systems Engineering: Faculty Publications

The writers appreciate the interest expressed by the discussers in this manuscript, and are pleased to have the opportunity to further discuss this material. The discussion states that the writers have generally examined a condition already investigated in other previous studies. Reynolds number values and roughness element size for the articles referenced by the discussers are shown in Table 5. Since flow rate and Reynolds number values were not given by Ferro and Giordano (1991), data from this study are not included in Table 5.
It can be seen from Table 5 that the roughness element sizes examined by Bathurst …

Patterns Of Morphological Variation Of Salsuginus Yutanensis (Monogenea: Ancyrocephalidae) Over Space And Time, Michael T. Ferdig, Mary Ann Mcdowell, John J. Janovy Jr., Richard E. Clopton

John J. Janovy, Jr. Publications

Salsuginus yutanensis occurs on the gills of the Plains topminnow Fundulus sciadicus Cope. The fish of this species have been found to vary morphologically and biochemically among disjunct populations. Morphological characteristics of the sclerotized parts of S. yutanensis were examined from three localities in Nebraska, over a 2-yr collecting period. Analysis of variance was used to assess morphological variation with respect to site and date. Worms from two localities, Keith and Saunders counties, differed significantly for most characters considered. A third site, also in Keith County, contained worms for which measurement means tended to be intermediate between those in the …

Host Specificity Of Calyptospora Funduli (Apicomplexa: Calyptosporidae) In Atheriniform Fishes, John W. Fournie, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Calyptospora funduli has a broad host specificity, infecting at least 7 natural and 10 additional experimental definitive hosts, all atheriniform fishes within 5 families, but most in the genus Fundulus. Barriers, apparently innate ones, prevent any development of C. funduli in perciform fishes but allow incomplete or abnormal development of the parasite in a few unnatural atheriniform hosts. In the freshwater species Fundulus olivaceus and Fundulus notti, these abnormalities consisted of asynchronous development, degeneration of the parasite in early stages of development, and the formation of numerous macrophage aggregates. Rivulus marmoratus has the ability to eliminate infections with …
