Methyl anthranilate (MA), a food grade flavor and fragrance additive, has been reported to be an effective non-lethal bird repellent in a variety of situations. Despite the experimental success of MA, field studies have yielded widely differing levels of efficacy. Diminished efficacy in some field trials prob­ ably results from the failure of specific formulations to retain or protect the active ingredient under natural conditions. Therefore, a clearer understanding of the physical and chemical factors affecting the stability of MA is needed. We undertook a series of laboratory studies on hydrolysis, photolysis and microbial degradation of MA, the results of …


Interaction Between Sensory And Postingestional Repellents In Starlings: Methyl Anthranilate And Sucrose, Larry Clark, J. Russell Mason Jan 1993

Interaction Between Sensory And Postingestional Repellents In Starlings: Methyl Anthranilate And Sucrose, Larry Clark, J. Russell Mason

Ingestion of concentrated sucrose solutions causes sickness in sucrase-defi­ cie_nt birds. As a result, some suggest that sucrose may represent an environmentally safe avian repellent. In the present experiments, we compared the repellency of sucrose to that of methyl anthranilate (MA), a known avian repellent. We also tested mixtures of sucrose and MA to investigate whether repellency could be enhanced, relative to sucrose or MA presentealo'!e. The results showed that the MA was strongly avoided in both drinking anf edmtnals. Conversely, only high sucrose concentrations were avoided, and only in dnnkmg tnals. No combination of MA and sucrose was as …
