Preparation and evaluation of a synthetic fermented egg coyote attractant and deer repellent

Strawberry‐Flavored Baits for Pharmaceutical Delivery to Feral Swine

Interestingly, coyotes avoided removing bait types with FeralMone attractant added, which was surprising in that FeralMone is based on a proprietary formulation of synthetic fermented egg (Bullard et al 1978) found to increase visitation and bait removal by red foxes (Vulpes vulpes) and wild dogs in Australia (Hunt et al 2007). Also surprising was our observation of visitation and removal of baits with FeralMone attractant by whitetailed deer because synthetic fermented egg has previously been determined to repel deer (Bullard et al 1978).…”

Also surprising was our observation of visitation and removal of baits with FeralMone attractant by whitetailed deer because synthetic fermented egg has previously been determined to repel deer (Bullard et al 1978). Our third hypothesis was that buried baits would be more specific to feral swine because of the greater below-ground foraging abilities of feral swine compared to nontarget animals in southern Texas.…”

Effect of a synthetic lure on site visitation and bait uptake by foxes (Vulpes vulpes) and wild dogs (Canis lupus dingo, Canis lupus familiaris)

“…Canid lure research undertaken in the United States (Bullard et al 1978, the UK (Saunders and Harris 2000) and Australia (Jolly and Jolly 1992;Mitchell and Kelly 1992) identified that peak performance of canid lures appears to occur during the breeding season of target animals. This may help to explain the lower interest by foxes during the initial Currango trial, which occurred during an extended period of high temperature before fox breeding season.…”

“…In the United States the effective use of organic and synthetic scents to lure coyotes (Canis latrans) to control points has been well documented (Linhart et al 1977;Bullard et al 1978Bullard et al , 1983Roughton and Bowden 1979;Phillips et al 1990;Kimball et al 2000), with similar work in Australia and the UK identifying the potential use of synthetic scent lures for canids (Jolly and Jolly 1992;Mitchell and Kelly 1992;Saunders and Harris 2000). The three latter studies all identified synthetic fermented egg (SFE) as having potential as a wild dog and/or fox lure.…”

The Application of Drift Spectroscopy to the Multicomponent Analysis of Organic Chemicals Adsorbed on Montmorillonite

“…Mixtures containing a wide range of organics such as carboxylic acids, amines, aldehydes, alcohols, alkyl aromatics, esters, ketones, terpenes and organo-sulphur compounds have been found to be attractive to coyotes in the United States of America (Preti et al 1976;Bullard et al 1978;Turkowski et al 1983) and to Dingoes in Australia (Mitchell and Kelly 1992). Controlling the rate of odor generated may be possible by initial adsorption of these chemicals onto montmorillonite, from which they would subsequently desorb over time.…”
