The Persistence and Secondary Poisoning Risks of Sodium Monofluoroacetate (1080), Brodifacoum, and Cholecalciferol In Possums
To determine the risk of secondary poisoning for animals preying on sub-lethally poisoned brushtail possums, captive possums were treated with near-lethal doses of sodium monofluoroacetate (1080) or brodifacoum, and toxicant concentrations in blood and tissue were monitored over time. Sodium monofluoroacetate was rapidly eliminated from the blood (within three days). Brodifacoum was retained in...
متن کاملAerial Prefeeding Followed by Ground Based Toxic Baiting for More Efficient and Acceptable Poisoning of Invasive Small Mammalian Pests
Introduced brushtail possums (Trichosurus vulpecula) and rat species (Rattus spp.) are major vertebrate pests in New Zealand, with impacts on conservation and agriculture being managed largely through poisoning operations. Aerial distribution of baits containing sodium fluoroacetate (1080) has been refined to maximise cost effectiveness and minimise environmental impact, but this method is stro...
متن کاملSocial interactions among captive brushtail possums (Trichosurus vulpecula).
A biological control strategy relying on a self-disseminating agent may provide the only affordable long-term technique for reducing brushtail possum (Trichosurus vulpecula) numbers throughout New Zealand. The objective of this study was to determine the frequency and patterns of social interactions in single and mixed-sex groups of possums, in order to identify interactions that may assist in ...
متن کاملSecondary and Tertiary Poisoning Risks Associated with Brodifacoum
The field use of brodifacoum baits (Talon® and Pestoff®) to control brushtail possums (Trichosurus vulpecula) has increased in recent years. This has raised concerns of secondary and tertiary poisoning, resulting from the transfer of this toxicant through the food chain. In New Zealand, feral pigs (Sus scrofa) are known to scavenge possum carcasses and may also gain access to bait stations cont...
متن کاملComparative Effects of Brodifacoum on Rats and Possums
The anticoagulant brodifacoum is widely used overseas as a rodenticide, and in New Zealand to control rodents and brushtail possums (Trichosurus vulpecula). The efficacy, behavioural and pathological changes and times to death were compared between Norway rats (Rattus norvegicus) and brushtail possums poisoned with brodifacoum. Caged animals were given brodifacoum in wax or cereal baits, observ...
