Rodent Repellent studies. III. Advanced Studies in the Evaluation of Chemical Repellents
Autor: Ervin Bellack, James B. DeWitt
Publikováno v: Journal of the American Pharmaceutical Association (Scientific ed.). 39:197-202
In order to bridge the gap between preliminary screening of chemicals for potential rodent repellency and the application of these compounds to paper cartons, more advanced studies in the evaluation of promising materials have been carried out. These

Rodent-repellent Studies. I. Method for the Evaluation of Chemical Repellents
Autor: Ervin Bellack, James B. De Witt
Publikováno v: Journal of the American Pharmaceutical Association (Scientific ed.). 38:109-112
A biological assay procedure and a method for the numerical expression of results have been devised for the determination of the repellency to rodents of different chemical compounds. The procedure is based upon the degree of acceptability of foods c
