Animal Welfare And The Control Of Vertebrates, Harry V. Thompson

Vertebrate Pest Conference Proceedings: 14th (1990)

The relationships between man and other animals have attracted increased attention and some controversy in recent years. Their importance in biomedical research, farming, and wildlife control are discussed in the United Kingdom context.

Rodents As A Food Source, Lynwood A. Fiedler

Vertebrate Pest Conference Proceedings: 14th (1990)

Rodents, one of several kinds of vertebrates included in the human diet, are very suitable as human food. More than 71 genera and 89 species of rodents, mostly hystricomorphs, have been consumed by man. Some have even been domesticated for private or commercial production of food for human consumption. Rodents in the temperate world serve only as a supplement to the regular diet of humans; but in the tropical world, they are widely accepted and a popular source of protein. Although harvesting field rats for human food is beneficial, it is not an effective pest control strategy. Consuming rodents in …

The Human Element In Wildlife Damage Situations, Ron J. Johnson

Vertebrate Pest Conference Proceedings: 14th (1990)

The field of prevention and control of wildlife damage is changing and evolving along with clientele needs, pressures from user and non-user groups, and other factors. A theoretical overview of the field may offer an action model regarding changing trends and potential responses. I propose that three things happen every time a wildlife damage problem occurs: 1) A human activity, desire, or need is interfered with, 2) the experience fosters an opinion about a wild animal - usually negative, and 3) a decision is made to tolerate the situation or to control it. If control is selected, availability and effectiveness …

Rabies Control For Urban Foxes, Skunks, And Raccoons, Richard C. Rosatte, Michael J. Power, Charles D. Macinnes, Kenneth F. Lawson

Vertebrate Pest Conference Proceedings: 14th (1990)

Rabies is currently enzootic in many cities of southern Ontario. The Ministry of Natural Resources is utilizing two different tactics for the control of rabies in urban wildlife rabies vectors-oral immunization with baits (foxes) and vaccination by injection following live-capture (skunks and raccoons). Between 47 and 79% of the skunks and 61 and 76% of the raccoons were captured and vaccinated (Imrab) in a 60-km2 urban area of Metropolitan Toronto during 1987, 1989. Only three cases of rabies in skunks have been reported since control began in 1987. Population increases of 120% for skunks and 40% for raccoons were noted …

Exclusionary Methods And Materials To Protect Plants From Pest Mammals--A Review, Rex E. Marsh, Ann E. Koehler, Terrell P. Salmon

Vertebrate Pest Conference Proceedings: 14th (1990)

Protecting individual plants or small clumps of plants with some type of protective material or device represents a positive nonlethal approach to damage prevention that is often much less expensive than fencing an entire garden or crop or netting over the entire area to prevent damage by such species as deer (Odocoileus spp.), rabbits (Lepus spp., Sylvilagus spp.), and ground squirrels (Spermophilus spp.). This review article does not include fencing or the netting or screening of entire crops, which are subjects unto themselves.

Use Of Alpha-Chloralose To Remove Waterfowl From Nuisance And Damage Situations, Paul P. Woronecki, Richard A. Dolbeer, Thomas W. Seamans

Vertebrate Pest Conference Proceedings: 14th (1990)

From 1988 through early 1990 alpha-chloralose (A-C) was successfully used in the United States to immobilize and remove 70 Canada Geese (Branta canadensis), 315 mallard, domestic and hybrid ducks (Anas platyrhynchos), and 348 coots (Fulica Americana) from 17 commercial and residential sites including golf courses, pools, and ponds. Field trials and baiting techniques with bread and corn are described. The optimum dose of A-C for geese, ducks, and coots, using orally administered bread and corn baits, was about 20-30 mg/kg. We are currently pursuing registration of A-C as a bird control chemical with the …

Frightening Methods And Devices/Stimuli To Prevent Mammal Damage-- A Review, Ann E. Koehler, Rex E. Marsh, Terrell P. Salmon

Vertebrate Pest Conference Proceedings: 14th (1990)

Various frightening stimuli, primarily visual and acoustic, have been used to prevent or alleviate damage by depredating mammals (e.g., deer (Odocoileus spp.), raccoons (Procyon lotor), tree squirrels (Sciurus spp.), coyotes (Canis latrans). Frightening methods are most appropriate for use where a crop or situation needs protection from pest mammals for only a period of a few days or weeks. The ability of animals to habituate to such stimuli limits their long-term usefulness. Against nocturnal species, various types of lights and noisemakers are the most useful. Combining acoustic and visual stimuli can enhance effectiveness, while …

Communal Starling Roosts: Implications For Control, Donald F. Caccamise

Vertebrate Pest Conference Proceedings: 14th (1990)

Roosting behavior is common to most avian pests of agriculture. Movements from highly aggregated distributions in roosts to highly dispersed distributions on foraging grounds determine pattern and severity of avian pest problems. This research seeks an understanding of how roosting behavior influences the dispersion of avian agricultural pests and the damage they cause. My focus is on why birds form communal roosts and how communal roosting influences the selection of foraging sites. I document patterns of roosting behavior in European starlings (Sturnus vulgaris) through population level studies, followed by analysis of individual behavior using radio telemetry. Starlings maintain …

Planning Rodent Control For Boston's Central Artery/Tunnel Project, Bruce A. Colvin, A. Daniel Ashton, Wellard G. Mccartney, William B. Jackson

Vertebrate Pest Conference Proceedings: 14th (1990)

A comprehensive rodent control program is being planned for a $4.4 billion highway-construction project in Boston, MA This IPM program will include broad participation by project personnel, city and state agencies, and community groups. Surveys, public education, and sanitation improvements will begin more than a year before construction; baiting will begin approximately 3 months before construction. All control activities will be maintained until construction is complete. Mitigation of community impacts during construction projects is a growing concern, and improved approaches to construction-related rodent control are needed.

Differential Toxicity And Taste Aversion To Strychnine Of Three Subspecies Of The California Ground Squirrel (Spermophilus Beecheyi), Walter E. Howard, Stephen D. Palmateer, Rex E. Marsh

Vertebrate Pest Conference Proceedings: 14th (1990)

Three subspecies of the California ground squirrel (Spermophilus beecheyi) were studied. In the first test of Experiment 1, Beechey (S. b. beecheyi), Douglas (S. b. douglasii), and, for comparative purposes, Sierra (S. b. sierrae) ground squirrels were each offered a drinking tube containing one of three H₂0 solutions of strychnine sulfate (0.01, 0.05, or 0.5%) after being deprived of water for 23 hr. In Test 2 the survivors of Test 1 were offered for 24 hr a free choice of distilled water and two of the above concentrations of strychnine …

The Use Of Rainfall Patterns In Predicting Population Densities Of Multimammate Rats, Mastomys Natalensis, H. Leirs, R. Verhagen, W. Verheyen

Vertebrate Pest Conference Proceedings: 14th (1990)

During 3 years we studied a population of multimammate rats, Mastomys natalensis (Smith 1834), in Morogoro, Tanzania. Data were collected in both removal and capture-recapture schemes. We present evidence that patterns of growth and reproduction were related to onset and abundance of rains. This partially explains differences in densities. Additionally, we investigated available literature data and related them with climatological data. A scenario is presented which enables us to predict how densities of multimammate rats may evolve in the following year and whether there will be a risk of outbreaks. The use and implications of this scenario in planning control …

The Development Of A Policy For The Management Of Dingo Populations In South Australia, R. J. Downward, J. E. Bromell

Vertebrate Pest Conference Proceedings: 14th (1990)

Competing concerns between conservation and sheep-growing interests in South Australia over problems associated with the naturalized dog,Canis familiaris dingo, prompted the development of a policy for the management of this subspecies. The background to the development of this policy is outlined. The policy provides for a compromise between the need to protect the livestock industry while ensuring the continued survival of the dingo as a wildlife species.

Cycloalexy: A New Concept In The Larval Defense Of Insects, Pierre Jolivet, Joao Vasconcellos-Neto, Philip Weinstein

Insecta Mundi

Anyone who has ever seen a Western will be familiar with the defensive tactics employed by the pioneers: The wagon train is formed into a ring, women and children on the inside, with the men firing out at the circling Indians. The larvae of some Coleoptera and Hymenoptera have long employed similar tactics, in defense against their predators (ants, bugs) and parasitoids (wasps, flies).

Distribution Of Polyploid Variation In Big Bluestem (Andropogon Gerardii, Poaceae) Across The Tallgrass Prairie Region, Kathleen H. Keeler

Kathleen H. Keeler Publications

The objective of this research was to describe the distribution of polyploid cytotypes of the grass big bluestem (Andropogon gerardii Vitman) along an east-west transect across the tallgrass prairie region, as an integral part of understanding the function of intraspecific polyploid polymorphism. Andropogon gerardii shows intraspecific variation in amount of nuclear DNA as a result of intraspecific poly-ploidy. Nearly 600 plants from 15 prairies in 5 states were collected and nuclear DNA was determined by flow cytometry. In the eastern part of the tallgrass prairie region, higher polyploids were rarely found. However, at the western edge of the tallgrass …

Viral Hemorrhagic Septicemia Of Fishes, Philip E. Mcallister

United States Fish and Wildlife Service: Publications

Viral hemorrhagic septicemia (VHS), a systemic infection of various salmonid and a few nonsalmonid fishes, is caused by a rhabdovirus designated as the viral hemorrhagic septicemia virus (Office International des Epizooties 1963). The virus infection occurs in salmonids and certain other fishes of any age and may result in significant cumulative mortality. Fish that survive may become carriers. Viral hemorrhagic septicemia has been reported under various names, of which "Egtved disease" and "Infektiose Nierenschwellung und Leberdegeneration" are the best known. The viral etiology of the disease was established by Jensen (1965), and several serotypes of the virus (also known as …
