Recent Studies On Flavor Aversion Learning In Wildlife Damage Management, Russell F. Reidinger Jr. Aug 1995

Recent Studies On Flavor Aversion Learning In Wildlife Damage Management, Russell F. Reidinger Jr.

National Wildlife Research Center Repellents Conference 1995

Flavor aversion learning (FAL) occurs experimentally when a mammal is presented with a distinctive-flavored food followed by a postingestional illness. Birds may learn aversions to visual cues. Aversions follow a single pairing and may be robust. During the past decade, at least four directions were followed in evaluating FAL for managing wildlife damage: compounds already registered for use on crops such as herbicides, insecticides, or fungicides were tested for their abilities to also repel birds and small mammals from crops; naturally occurring compounds such as sucrose or charcoal were similarly evaluated; eggs were treated with different compounds in attempts to …


An Integrated Strategy To Decrease Eared Dove Damage In Sunflower Crops, Ethel N. Rodriguez, Richard L. Bruggers, Roger W. Bullard, Robert Cook Aug 1995

An Integrated Strategy To Decrease Eared Dove Damage In Sunflower Crops, Ethel N. Rodriguez, Richard L. Bruggers, Roger W. Bullard, Robert Cook

National Wildlife Research Center Repellents Conference 1995

Eared doves (Zenaida auriculata) damage mature sunflowers in Uruguay. Although repellents might be useful as a control method, durability and expense have discouraged their use. In the present report, we describe laboratory, aviary, and field research designed to evaluate methiocarb and calcium carbonate as durable, economical repellents. Calcium carbonate (CaCO3) was as effective as CaCO3 /methiocarb in combination in deterring consumption of sunflowers. Moreover, treating field borders with CaCO3 or the CaCO3 /methiocarb combination was as effective as treating the entire field for at least 12 days. This period is sufficiently long to …


Ripening Field Corn Lost To Wildlife In 1993, Alice P. Wywialowski Apr 1995

Ripening Field Corn Lost To Wildlife In 1993, Alice P. Wywialowski

Great Plains Wildlife Damage Control Workshop Proceedings

Ripening field corn lost to wildlife was measured in fall 1993 in 10 midwestern states that have produced 83% of the field corn in the United States over the past 10 years. Sampling of damage was stratified by producer expectation of likely wildlife damage or unlikely wildlife damage. Damage was assessed immediately before harvest. Two plots that measured 4.5 m x 2 rows were assessed in each selected field. Of assessed fields, wildlife damage was present in 340 of 1,259 (27.0%) likely damaged fields and 108 of 1,243 (8.7%) unlikely damaged fields. As a percentage of harvested production, birds (Aves) …


Livestock Herding Dogs: A Unique Application For Wildlife Damage Management, Roger A. Woodruff, Jeffrey S. Green Apr 1995

Livestock Herding Dogs: A Unique Application For Wildlife Damage Management, Roger A. Woodruff, Jeffrey S. Green

Great Plains Wildlife Damage Control Workshop Proceedings

Canada geese (Branta canadensis) and white-tailed deer (Odocoileus virginianus) have caused increasing problems for people both in urban and agricultural environments. In many instances, traditional methods of resolving conflicts caused by these species have proven ineffective or impractical. Some property owners and others have begun to use livestock herding dogs to haze geese and other wildlife from areas where they are not wanted. We report on the applications and effectiveness of this technique as employed on golf courses, farms, and other areas. The use of trained herding dogs appears to be a feasible and effective method …


Advancing Deer Repellent Performance: Fine-Tuning Hinder Applications And Potential Uses For Insecticidal Soaps, Michael J. Fargione, Milo E. Richmond Oct 1993

Advancing Deer Repellent Performance: Fine-Tuning Hinder Applications And Potential Uses For Insecticidal Soaps, Michael J. Fargione, Milo E. Richmond

Sixth Eastern Wildlife Damage Control Conference (1993)

Deer feed on buds, shoots, leaves and fruit (Scott and Townsend 1985), and cause substantial economic losses for many apple producers (Purdy et al. 1987). A variety of mitigation techniques are used to control such damage including deer population reduction via hunting, exclusion fencing and scare devices. However, most commercial apple producers rely on home-made or commercial repellents to control deer damage (Purdy et al. 1987). Despite their popularity, repellents have often provided only limited or highly-variable control (Conover 1984, 1987, Hygnstrom and Craven 1988). There is considerable need to improve the performance of existing repellents, or to identify new …


Status And Management Of Vole Damage To Horticultural Plantings In North Carolina, Peter T. Bromley, William T. Sullivan Jr. Oct 1993

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

Sixth Eastern Wildlife Damage Control Conference (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 …


Deer Damage In Tennessee: Landowner Perceptions And Attitudes, Michael M. King Oct 1993

Deer Damage In Tennessee: Landowner Perceptions And Attitudes, Michael M. King

Sixth Eastern Wildlife Damage Control Conference (1993)

Survey results suggest that the most common perception among Tennessee landowners is that during the last five years the white-tailed deer population has increased. Over 43% of survey respondents indicated that they felt there are more deer now than five years ago. However, in spite of the general agreement that the deer population has increased, less than 20% of the respondents indicated that there was more damage now than five years ago. When asked about amount of damage they had experienced from deer during the last year, 67.3% answered that they had experienced no damage while 32.6% incurred some damage …
