Résumé :	Egg- baits prepared by the insertion of a 1080 ( sodium fluoroacetate)- treated rhodamine- dyed oat- grain into each egg are used for controlling foxes ( Vulpes vulpes) in Australia. However, the diffusion pattern of 1080 from the inserted oat into the egg and the distribution of 1080 within the egg are unknown. As both factors will influence whether the target species needs to consume the oat to receive a lethal dose, and also the withholding period required before the baits can be laid, we examined the rate of diffusion and the ultimate distribution of 1080 within these baits. Rhodamine oats containing 4.5 mg of 1080 were inserted into the white of intact eggs, or into eggs where the white and yolk was mixed ( scrambled). 1080 rapidly dispersed into the eggs ( but not the yolk of intact eggs) irrespective of which technique was used:
