Feral swine (Sus scrofa) are one of the most threatening mammalian pest species in North America owing to the damage they cause to natural habitats and agroecosystems, and the risk of disease transmission they pose to wildlife, livestock, and humans. The long-term (> 1 year) effects of lethal control efforts on feral swine populations at local scales are largely unknown. Using a panel of molecular markers, we assessed the effects of lethal control efforts on selected populations of feral swine in southern Texas. We collected tissue samples from two sites during removal campaigns, extracted and amplified DNA, and …

There are no registered toxins available for use on Feral Swine (Sus scrofa, Linnaeus) in the United States. HOGGONE is a proprietary bait matrix under development in Australia that delivers toxic levels of sodium nitrite to feral swine. However, one challenge is to develop a species-specific oral delivery system to deliver toxins to feral swine in the USA while minimizing non-target wildlife exposure. The HOGHOPPERTM is a lightweight and portable bait delivery system that could overcome this problem. Our objective was to compare non-toxic HOGGONE removal by wildlife that visited HOGHOPPERS during acclimation periods (doors open; free-feeding …

After the reproductive period, blackbirds in the northern Great Plains aggregate in large flocks that feed on ripening crops, especially sunflower. At today’s prices, blackbirds eat about $8–12 million of sunflower annually in northern Great Plains, with most of this damage occurring in North Dakota and South Dakota (Peer et al. 2003). Additional expenditures are incurred by producers trying to protect their crop, including the costs in time, travel, and materials for hazing blackbirds. A chemical feeding repellent would be ideal for protecting sunflower from blackbirds because it would not only cut the amount of losses from foraging but also …
