The Toxicity of Sodium Monofluoroacetate to Wild Rabbits, Oryctolagus Cuniculus (L.), From Three Sites in Western Australia.

Abstract

The LD50 of sodium monofluoroacetate for wild rabbits was determined in the field at three well separated sites in Western Australia, and in the laboratory using rabbits from one of the sites. At one site the rabbits had not been exposed to fluoroacetate, while at the other two it occurred naturally in native plants of the genera Gastrolobium and Oxylobium, as well as having been used in rabbit-control baits. No differences were detected in LD50 values from the three sites. Pressures for selection for tolerance to fluoroacetate in wild rabbits are discussed.
