Nonlethal Bird Repellents: In Search Of A General Model Relating Repellency And Chemical Structure, Larry Clark, Pankaj Shah

Larry Clark

Identification of potential repellents through molecular modeling has implications for the devel­ opment of commerciaUy viable, ecologically sound. nonlethal bird repellents. We tested isomers (ortho, meta, para) and moieties (amino, hydroxy, methoxy) of acetophenones for their effectiveness as bird repellents to better understand the nature of repellency in birds. ChemicaUy, basicity of a substituted phenyl ring, as de&ned by the electron-donating substituent, probably is an important feature infiuencing repellency; i.e., more basic substituents result in more potent repellents. Isomeric position of the electron-donating substituent, which leads to resonance of lone pairs of electrons.• is also an important feature of repellency; …
