Influence Of The Number Of Repellent-Treated And Untreated Food Or Water Containers On Intake By The European Starling, Arla G. Hile, Michael G. Tordoff
Influence Of The Number Of Repellent-Treated And Untreated Food Or Water Containers On Intake By The European Starling, Arla G. Hile, Michael G. Tordoff

The availability of multiple sources of food and drink has a profound influence on choice behavior in rodents. It is not known how other taxa might respond to the same kind of variation in availability. We tested European starlings (Sturnus vulgaris) with various combinations of unadulterated and repellent-treated (0.025% citronellyl acetate) resources. In Experiment 1, birds drank more plain than repellent-treated water than when given (a) 2 bottles of plain water and 2 of repellent-water, or (b) 3 bottles of plain water and 1 of repellent-water. However, they drank more repellent than water when given 3 bottles of repellent-water and …
Effects Of Taste Stimuli (Quinine And Sucrose) In Pelleted Granulated, And Wax Block Baits On Feeding Preferences Of Northern Pocket Gophers (Thomomys Talpoides), Stephen A. Schumake, Geraldine R. Mccann
Effects Of Taste Stimuli (Quinine And Sucrose) In Pelleted Granulated, And Wax Block Baits On Feeding Preferences Of Northern Pocket Gophers (Thomomys Talpoides), Stephen A. Schumake, Geraldine R. Mccann
Vertebrate Pest Conference Proceedings: 18th (1998)
A two-choice, taste preference study was conducted using 18 northern pocket gophers to evaluate pelleted sorghum, granulated sorghum, and wax block baits containing either 0.01 to 0.05 % quinine or 0.10 to 5.0 % sucrose. Bait consumption was significantly higher across treatments (P≤.001) for granulated sorghum, followed by pelleted sorghum, and wax blocks. Gophers also showed a high frequency of moving the granulated bait in their cheek pouches to be deposited at alternate locations within their cages. Although increasing sucrose concentration did not produce significantly (P ≥.10) enhanced consumption for any of the baits, a trend toward increasing preference with …

Mammal Repellents: Options And Considerations For Development, J. Russell Mason
Vertebrate Pest Conference Proceedings: 18th (1998)
Repellents include chemical substances, visual displays, and sonic and ultrasonic deterrent systems. The use of electric shock also can be considered as a repellent category. Each of these categories is discussed, together with their respective utilities, constraints on their usefulness, and possibilities for future development. Economic considerations that may impede or expedite the development of new strategies are presented. Repellent effectiveness depends upon a complex of variables, including the palatability of protected and alternative foods, weather conditions, and the number of animals causing problems. Invariably, repellents are most useful when used as components of integrated pest management strategies

Chemical Signals And Repellency: Problems And Prognosis, Gary K. Beauchamp
National Wildlife Research Center Repellents Conference 1995
The chemical senses (olfaction, gustation, and chemical irritation or pain) were likely the first to evolve. Their functions are among the most basic-to attract and to repel. Attracting compounds often signal food or sex; repelling compounds presumably signal danger. Among the chemical senses, only olfaction appears to have several functional roles, two of which are modulation of social behaviors and identification of food. Whether an odor attracts or repels often depends to a large degree on learning. Consequently, dissociated olfactory stimuli may be relatively poor candidates for repellents since, after repeated exposure, pest animals are likely to ignore them. Taste, …
Development Of A Bait For The Oral Delivery Of Pharmaceuticals To White-Tailed Deer (Odocoileus Virginianus), J. Russell Mason, N.J. Bean, Larry S. Katz, Heidi Hales

Contraception in Wildlife Management
Solid and liquid baits were tested for the delivery of drugs to white-tailed deer. The solid bait was compromised of a mineral block paired with apple, peanut butter, or acorn extract. The liquid bait was compromised of water, apple juice, glycerine, salt, and either peanut butter or apple odor. Although both solid and liquid baits were attractive to deer, the latter may be more useful because consumption can be measured directly, ingestion by nontarget animals is minimized, and bait degradation by weathering is reduced.
