Use of Sodium Fluoroacetate (Compound-1080) in the Control of Dingoes .1. Meat Bait Preparation Techniques

Abstract

Injection and mixing techniques for the preparation of fresh meat baits containing sodium monofluoroacetate (1080) were evaluated. Both techniques produced baits containing variable quantities of 1080. The injection of 1 ml of 6.0-mg ml-1 1080 and 0.5 ml of 13.6-mg ml-1 1080 solution produced baits containing (mean ± SD) 2.9 ± 0.6 and 3.5 ± 0.5 mg of 1080 respectively; the ranges were 1.9-4.1 and 2.1-4.4 mg respectively. Decreasing the injection volume while increasing the 1080 concentration did not increase the percentage of 1080 recovered from baits. Mixed baits prepared by tumbling with 1 ml of 5.7-mg ml-1 1080 and 1 ml of 10-mg ml-1 1080 per bait contained 3.8 ± 1.9 and 5.3 ± 2.1 mg of 1080 respectively, with respective ranges of 1.2-11.3 and 1.2-13.2 mg per bait. The injection method produced baits more uniform with respect to the amount of 1080 in the bait. A significant fraction of the 1080 added in both methods of preparation was not found. Experiments showed that this loss was due to biochemical reaction rather than physical loss.
