New developments in vertebrate pest control technologies
‘Silver bullets’ and better mouse traps capture the imagination of pest managers, but while development of new technologies for eff ective pest control is one important aspect of Landcare Research’s science programme, pest control is much more complex than ‘new tools’ or ‘just killing animals’.
Developing species-selective novel control tools for pest control
Most vertebrate pest control has been achieved through the use of acute poisons and first- and second-generation anticoagulants. Collectively, these poisons have varying degrees of success but one common disadvantage – they are all broad-spectrum and pose primary and secondary non-target risks to humans, domestic pets, wildlife, and livestock.
Sex pheromone attractants to improve the trapping and monitoring of mammal pests at low densities
Janine Duckworth has been investigating whether sex pheromone lures increase the encounter and interaction rates of possums and stoats with traps or monitoring devices.
Camera traps for monitoring cat, stoat and hedgehog populations
Camera traps (trail cameras) are useful for monitoring wildlife, but until recently have only been used to monitor relatively large animals. Their use with small animals presents some challenges.
The Trojan Female Technique: a novel nonlethal approach for pest control
The Trojan Female Technique is a novel and cost-effective technology platform for the specific (i.e. no potential for non-target effects), persistent, non-lethal and non-GMO (genetically modified organism) control of vertebrate and invertebrate pests.
Improving baiting for rabbit control and minimising risks to non-target animals
Research into improvements to the cost-efficacy of aerial baiting for rabbit control, and reassessment of the non-target risks associated with this control method.
Repellents to protect native birds from 1080 baits
New research on bird repellents may provide a means to further reduce the risk of deaths of native birds from aerially sown baits for possums and rats.
Precision aerial sowing of baits for possum control
Aerial baiting is a crucial technology in possum and rat control, and for over 20 years has involved sowing from a helicopter along GPS-guided parallel flight paths 100–200 m apart.
Evaluating and prioritising community-based biodiversity conservation projects
Tools that evaluate the costs and benefits of environmental projects and allow them to be compared and ranked are used to evaluate and prioritise community-led species conservation projects from the perspective of potential tool users.
Remote monitoring of traps and vertebrate pests
Remotely monitoring traps and other detection devices could significantly reduce servicing costs and provide near-real-time information from the field.
Trapping stoats and ship rats – a low-cost option for their control
The modified Victor® Easy Set® trap provides a low-cost, low-weight, humane trapping option for community groups to control stoats and ship rats.
Using radio frequency identification technology to measure possum interaction rates with traps
Using radio frequency identification technology to measure possum interaction rates with traps.
Single or multiple capture traps – what should you buy?
Deciding what is the most cost-effective option requires an understanding of how many captures a trap might have at a single site over the time between checks.
Lynne Freeman talks to Dr Andrea Byrom (Landcare Research), Devon McLean from the Predator Free New Zealand Trust, Forest and Bird's Kevin Hackwell, and Paul Jansen about the feasibility of a Predator Free New Zealand.
