The Prospects And Associated Challenges For The Biological Control Of Rodents, Grant R. Singleton
The Prospects And Associated Challenges For The Biological Control Of Rodents, Grant R. Singleton
Proceedings of the Sixteenth Vertebrate Pest Conference (1994)
Biological control using macro- or micro-parasites is a promising research area for control of rodents. The largest impediment to progress is a dearth of high quality research, under field conditions, on wild rodents and their diseases. A major challenge is to identify a candidate control agent which is sufficiently pathogenic, has a high transmission rate and is target specific. Once this has been done, ecological studies of both the host and the disease agent, and of the epidemiology of transmission, are required. Whether the desired pathogenicity is via increased mortality and/or reduced fertility will depend on the agent and on …
Using Geographic Information Systems For Tracking An Urban Rodent Control Program, Matt Von Wahlde, Bruce A. Colvin
Using Geographic Information Systems For Tracking An Urban Rodent Control Program, Matt Von Wahlde, Bruce A. Colvin
Proceedings of the Sixteenth Vertebrate Pest Conference (1994)
Geographic information system technology is being used to help coordinate an urban rodent control program initiated as part of the Central Artery/Tunnel Project in Boston. Databases with neighborhood survey data, surface and subsurface baiting data, sanitation code violations, and public complaints are linked to base mapping, land parcel, and utility graphics. This integrated approach helps Project biologists plan control strategies and evaluate the relatedness of rodent activity to environmental conditions. Spatial querying techniques and the ability to graphically display and map variables, such as bait stations and sanitation deficiencies, help ensure that control resources are effectively targeted and tracked. This …
Biological Management (Control) Of Vertebrate Pests-Advances In The Last Quarter Century, Scott E. Hygnstrom, Kurt C. Vercauteren, Thomas R. Schmaderer
Biological Management (Control) Of Vertebrate Pests-Advances In The Last Quarter Century, Scott E. Hygnstrom, Kurt C. Vercauteren, Thomas R. Schmaderer
Proceedings of the Sixteenth Vertebrate Pest Conference (1994)
In 1967, Howard provided a review of biological control of vertebrate pests. The term "biological control" was borrowed from the field of entomology, where it has been traditionally defined as "the reduction in number or density of pests through biological processes such as predation, pathogens, habitat modification, and fertility control." Current philosophy in wildlife damage management advocates "the reduction of damage to a tolerable level" rather than "the reduction of the number or density of vertebrate pests." Therefore we abdicate the term "biological control" and encourage the use of a new term, "biological management" of wildlife damage. Advances in science …
The Role Of Predators In The Ecology, Epidemiology, And Surveillance Of Plague In The United States, Kenneth L. Gage, John A. Montenieri, Rex E. Thomas
The Role Of Predators In The Ecology, Epidemiology, And Surveillance Of Plague In The United States, Kenneth L. Gage, John A. Montenieri, Rex E. Thomas
Proceedings of the Sixteenth Vertebrate Pest Conference (1994)
Predators play important roles in the ecology, epidemiology, and surveillance of plague in the United States. Most predators are accidental hosts of plague and, with the possible exception of grasshopper mice (Onychomys spp.), are not important sources of infection for feeding fleas. However, predators undoubtedly do play an important role in the natural cycle of plague by transporting infected fleas between different populations of plague-susceptible rodents. Predators are known to be at least accidental hosts for 40 of the 50 flea species that have been found to be naturally infected with plague in the U.S. Carnivores, including domestic cats, …
California Ground Squirrels At Concord Naval Weapons Station: Alternatives For Control And The Ecological Consequences, Ivette Loredo-Prendeville, Dirk Van Vuren, Amy J. Kuenzi, Michael L. Morrison
California Ground Squirrels At Concord Naval Weapons Station: Alternatives For Control And The Ecological Consequences, Ivette Loredo-Prendeville, Dirk Van Vuren, Amy J. Kuenzi, Michael L. Morrison
Proceedings of the Sixteenth Vertebrate Pest Conference (1994)
This paper presents a methodological approach that was recently developed to determine alternatives for control of California ground squirrels (Spermophilus beecheyi) and the resulting ecological consequences at the Concord Naval Weapons Station (CNWS). The U.S. Navy initiated this study upon determining a need to control ground squirrels for safety reasons. The squirrel's ecological role at CNWS was examined by estimating squirrel abundance and distribution throughout CNWS, analyzing predator diets, and determining the squirrel's relationship to the California tiger salamander (Ambystoma californiense). In addition, the efficacy of live capture and translocation of squirrels as a possible control …
