Evaluation of a Bio-dynamic Technique for Possum Pest Control
نویسندگان
چکیده
Bio-dynamic control involves burning pest tissue or organs and spreading the ash on areas to be protected. In New Zealand, bio-dynamic methods have been suggested for repelling possums where they damage forests or spread disease. We assessed the repellent effects of five bio-dynamic tinctures. First we tested these materials on possums in pens and noted their effects on foraging behaviour, food consumption, and body weight. Then we monitored bait consumption from treated and untreated feeder stations in the field. Although an orthodox herbivore repellent significantly deterred possums, we detected no behavioural or repellent effects of the biodynamic tinctures in any of our trials. We are unable to recommend these tinctures for possum control.

Ship rat demography and diet following possum control in a mixed podocarp–hardwood forest
Control of one pest species may permit increases in abundance of other pests, thereby reducing the overall net benefit from pest control. We provide evidence that control of introduced possums (Trichosurus vulpecula) may increase ship rat (Rattus rattus) abundance in some New Zealand native forests. Ship rat abundance in a podocarp–hardwood forest was assessed using simple interference indices ...
متن کاملThe Development of Long Term Management Plans for Bovine Tb Possum Control
In parts of New Zealand the beef and dairy industry is being threatened by possums spreading bovine tuberculosis to cattle. As a result new strategies for the long term control of possum populations have been developed. For these strategies, management plans are prepared which detail the control programme for each area. New control strategies are being developed which include long term annual c...
متن کاملA review of the potential of fertility control to manage brushtail possums in New Zealand
Brushtail possums (Trichosurus vulpecula) were introduced into New Zealand from Australia in the mid-1800s and became a major invasive pest. They damage native biodiversity by browsing and predation, and they are a disease risk to the livestock industry by acting as vectors of bovine tuberculosis (TB). Management of possums includes their eradication from some offshore islands and control by tr...
متن کاملThe Evaluation of Alternative Toxins to Sodium Monofluoroacetate (1080) for Possum Control
Possum control in New Zealand is dependent on the use of sodium monofluroacetate (1080) and cyanide. Although 1080 is highly effective, its use is restricted to government staff. Cyanide is available for a wider group of licensed operators, but cyanide "shyness" reduces its effectiveness. An acute toxicity programme has been set up to identify nonanticoagulant toxins that could be used safely b...
متن کاملManaging and eradicating wildlife tuberculosis in New Zealand
Tuberculosis (TB) due to Mycobacterium bovis infection was first identified in brushtail possums (Trichosurus vulpecula) in New Zealand in the late 1960s. Since the early 1970s, possums in New Zealand have been controlled as part of an ongoing strategy to manage the disease in livestock. The TB management authority (TBfree New Zealand) currently implements three strategic choices for disease-re...
