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

Abstract

Application of synthetic fermented egg (SFE), via aerosol, to the surface of bait stations increased site visitation by wild dogs and foxes when compared with the use of buried baits alone. An associated increase in bait uptake by foxes at SFE-treated bait stations was observed when compared with bait uptake at untreated stations, although this effect diminished with time, possibly due to the use of non-lethal baits leading to the discovery of all bait stations and the habituation of animals to sites of reward. Bait uptake by wild dogs, although limited, occurred only at stations treated with SFE. Use of an aerosol based form of SFE allowed an ease of field application not previously associated with the use of synthetic lures.

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).…”

“…We hypothesized that 1) baits with strawberry-flavored feed additive would be specific to feral swine, based on previous findings (Campbell and Long 2008); 2) baits with FeralMonet attractant (Pestat; Proprietary Limited Company, Bruce, Australian Capital Territory, Australia), an aerosolized formulation of synthetic fermented egg, would display high feral swine removal, following findings for carnivores from Australia (Hunt et al 2007); and 3) buried baits would be more specific to feral swine because of the greater below-ground foraging abilities of feral swine compared to nontarget animals.…”

Feasibility of using Scent-Baited Hair Traps to Monitor Carnivore Populations in Peninsular Malaysia

“…, 25]. As the attractiveness of lures can also vary with season and location [25, 26], further work is required to determine whether our lack of dhole detection was an artifact of our sampling regime.…”

“…Animals which travel to investigate the 'call lure' would move into the range of the 'trap lure' and hopefully interact with the hair trap [e.g., 25]. As the attractiveness of lures can also vary with season and location [25,26], further work is required to determine whether our lack of dhole detection was an artifact of our sampling regime.…”
