Disaccharide Intolerance Of European Starlings, Leonard R. Askham
Disaccharide Intolerance Of European Starlings, Leonard R. Askham
Proceedings of the Seventeenth Vertebrate Pest Conference 1996
The use of disaccharides to discourage bird depredation to agricultural crops has elicited some interest during the last few years. Data developed in these trials indicate that several avian species are intolerant to sucrose because of the lack of sucrase enzymes in their digestive systems. Based on this research it is hypothesized that progressively increasing rates and volumes of solutions would elicit consistent adverse stress reactions. Furthermore, that if birds were intolerant to sucrose, because of their co-evolutionary development with plants, then they should lack the ability to digest lactose. The data developed in these trials does not support either …

Introducing The National Wildlife Research Center, Richard D. Curnow
Proceedings of the Seventeenth Vertebrate Pest Conference 1996
The paper summarizes the background and historical events leading to the creation of the National Wildlife Research Center (NWRC) and describes the status of its research program and facilities development in Fort Collins, Colorado. Also, the relationship of the NWRC to the Denver Wildlife Research Center is presented.
Nest Material As A Delivery Method For Avicides: Preliminary Tests With African Weaver Finches, Stephen A. Shumake, Peter J. Savarie
Nest Material As A Delivery Method For Avicides: Preliminary Tests With African Weaver Finches, Stephen A. Shumake, Peter J. Savarie
Proceedings of the Seventeenth Vertebrate Pest Conference 1996
To evaluate the potential of using nesting material as a medium for avicide delivery, five organophosphates (Dasanit®, Volaton®, fenthion, parathion, and Cyanophos®) were tested on small groups of paired male-female quelea (n = 4 to 9). Toxicants were presented to each pair of birds on five 13-cm strands of cotton string after a preliminary screening for male nest weaving behavior. Tested concentrations ranged from 100% technical grade to 0.003 % compound diluted with acetone. Dasanit® was found to be the most effective candidate with some lethal effects noted at 0.012%. An optimal concentration …

Plant Secondary Chemicals As Non-Lethal Vertebrate Repellents, Richard W. Watkins, David P. Cowan, Elaine L. Gill
Proceedings of the Seventeenth Vertebrate Pest Conference 1996
Few effective repellents are currently available for the non-lethal management of vertebrate pests. This is perhaps not surprising considering the ad hoc nature of past applications which assumed that the target pest species would have the same attraction/aversion preferences as man. A more rational approach is to identify compounds that have real biological significance for the pest species. Plants have evolved an array of defense chemicals (secondary plant compounds) that inhibit the feeding of vertebrate herbivores, because they are either innately aversive or they generate a conditioned aversion. These compounds are, therefore, ideally suited for use in the reduction of …
