It is believed that mammalian chemosensory initants are not aver sive to birds and vice versa. Nevertheless, few avian repellents have been tested against mammals. For that reason, we evaluated the efficacy of 1.0% w/v methyl anthranilate, orthoaminoacetophenone, 2-amino-4' ,5 '-methoxy acetophenone, 2-methoxyacetophenone, and veratryl amine as mouse repel lents in 3-hr no-choice drinking tests. Relative to ingestion of plain water, all test substances significantly reduced (P < 0.05) intake. Orthoaminoacetophenone was the most effective repellent, with intake reduced to levels statistically indistinguishable from zero.

At least some anthranilates (e.g., methyl anthranilate), and ace tophenones (e.g., orthoaminoacetophenone) are aversive to mice as well as to birds. Here we systematically examined nine acetophenone isomers (ortho, meta, para) and moieties (amino, hydroxy, methoxy) previously tested as drinking and feeding repellents for European starlings (Sturnus vulgaris). All nine substances reduced intake by mice in single-bottle tests. When molecular characteristics were examined, amino group reactivity and, to a lesser extent, isomeric position (i.e., resonance), were related to the strength of the avoid ance response. Unlike effective avian repellents, the presence of intramo lecular hydrogen bonds did not appear to …
