Abstract
Field studies and bounty records indicate that foxes (Vulpes fulva and Urocyon cinereoargenteus) may be effective agents in the reduction and control of weasels (Mustela frenata nove-boracensis, M. cicognanii, and M. rixosa allegheniensis) in Pennsylvania. Bounty figures (1930 to 1951) for both weasels and foxes show*that an inverse relationship exists between the number of foxes and the number of weasels killed annually. Individual counties exhibited this same trend. An analysis of bounty figures also revealed that counties with an annual weasel kill between 1 and 99 had an average weasel-fox ratio of 1:9.33, but this ratio was gradually reduced until counties killing 500 or more weasels annually had a weasel-fox ratio of 1:0.99.This publication has 0 references indexed in Scilit:
