Appropriate Amounts of 1080 Poison in Baits to Control Foxes, Vulpes-Vulpes

摘要

Data are presented on the sensitivity of foxes to 1080 poison which, although not meeting thenrequirements for calculation of a precise LD 50, provide a basis for determining the appropriate amountnof 1080 to use in baits to control foxes. Amounts of 2.5 mg per bait appear ample, based on the lethalndose of c. 0.15 mg kg-' for foxes, but further trials may be necessary to confirm whether this providesnsufficient allowance for possible reduced bioavailability and reductions in 1080 concentration in meatnbaits under different environmental conditions.
