Ortho-Aminoacetophenone Repellency To Birds: Similiarities To Methyl Antrhanilate, Russell Mason, Larry Clark, Pankaj Shah

Larry Clark

Methyl anthranilate is an effective bird repellent at concentrations 2:1.0% (g/g). Ortho-ami­ noacetophenone (OAP) has an odor similar to that of methyl anthranilate and is chemically (structurally) similar. Coincidentally, OAP is present in the scent gland secretions of mustelid species that prey on birds. For these reasons, we chose to test the bird repellency of this material and 3 isomers to European starlings (Stumus vulgaris). Ortho-aminoacetophenone was repellent at concentrations :50.01% in both choice and no-choice feeding tests. The other structural isomers (meta-, para-, alpha-) were less effective. Chemically, the results suggest that hydrogen-bonded ring structure formation and basicity predict …
