Effectiveness of the bird repellents anthraquinone and d-pulegone on an endemic New Zealand parrot, the kea (Nestor notabilis)
Contributor(s):: Orr-Walker, Tamsin, Adams, Nigel J., Roberts, Lorne G., Kemp, Joshua R., Spurr, Eric B.
The toxin 1080 (sodium fluoroacetate) is widely used to control introduced mammalian pests in New Zealand. By-kill of non-target native species, particularly birds, does occur including that of the endemic New Zealand parrot, the kea (Nestor notabilis). In large-scale control operations the toxin...
New food baits for trapping house mice, black rats and brown rats
Contributor(s):: Takács, Stephen, Musso, Antonia E., Gries, Regine, Rozenberg, Emma, Borden, John H., Brodie, Bekka, Gries, Gerhard
We have recently developed new food baits (SFU Mouse Bait, SFU Rat Bait) for trapping granivorous house mice, Mus musculus, and black rats, Ramis rattus, and for trapping omnivorous brown rats, Rattus norvegicus. Both baits contain synthetic long-range volatile food attractants that represent...
Natural bait additives improve trapping success of common voles, Microtus arvalis
Contributor(s):: Schlötelburg, Annika, Jakob, Gerhard, Bellingrath-Kimura, Sonoko, Jacob, Jens
Common voles are serious pests in European agriculture, damaging cereals, rapeseed and other crops and causing substantial losses per outbreak. Not only might the usual approach of applying rodenticides for population management have disadvantages for non-target species, these rodenticides also...

A Quantitative Analysis of Kalandars and Captive Bears in Pakistan
Contributor(s):: Thomas P. Rooney, Kendra C. Millam
In 2013, the Bioresource Research Centre (Islamabad, Pakistan) conducted a comprehensive census of the remaining dancing and bear-baiting bears in Pakistan. This involved locating and counting the actual involved bears and bear keepers (kalandars), collecting detailed socio-economic data from the...
Individual hunting behaviour and prey specialisation in the house cat Felis catus: implications for conservation and management
Contributor(s):: Dickman, C. R., Newsome, T. M.
Predators are often classed as prey specialists if they eat a narrow range of prey types, or as generalists if they hunt multiple prey types. Yet, individual predators often exhibit sex, size, age or personality-related differences in their diets that may alter the impacts of predation on...

Conditioned taste aversion in the grey fox ( Pseudalopex griseus), in Southern Argentine Patagonia
Contributor(s):: Nielsen, S., Travaini, A., Vassallo, A. I., Procopio, D., Zapata, S. C.
Attempts to control cougar ( Puma concolor) and culpeo fox ( Pseudalopex culpaeus) populations in Patagonia through poisoning, negatively affects grey foxes ( Pseudalopex griseus) and many other non-target species. It is therefore advisable to develop selective predator control methods. Among a...
Zinc phosphide rodenticide reduces cotton rat populations in Florida sugarcane
Contributor(s):: Nicholas R. Holler, David G. Decker
Rodents cause extensive damage to sugarcane (Saccharum spp. hybrids) in southern Florida (Samol 1972). Losses have been estimated as high as $235/ha (Lefebvre et al. 1978). Cotton rats (Sigmodon hispidus) and roof rats (Rattus rattus) are responsible for most of the damage (Holler et al. 1981)....
Trapping: A continuous integral part of a rodent control programme
Contributor(s):: H.R. Shuyler, R.F. Sun Jr.
Trapping is usually considered a rodent control technique of minor importance. Due to the economic situation in the Dumaguete, Philippines program from which this report is drawn, regular trapping was a biological necessity. Four species of rodents and a shrew were of concern. A continuing daily...
A novel strategy for pocket gopher control
Contributor(s):: Michael E.R. Godfrey
Current techniques for the control of pocket gophers use traps, fumigants or toxic baits. Trapping and fumigation are labor intensive and seldom effective in giving more than short-term relief. Toxic baiting usually uses baits that are rapidly degraded and although the resident gopher may be...
Hazards to wildlife associated with underground strychnine baiting for pocket gophers
Contributor(s):: Paul L. Hegdal, Thomas A. Gatz
Under an Environmental Protection Agency (EPA) contract, we evaluated the hazards associated with strychnine baiting for pocket gophers (Geomys bursarius) with the burrow-builder. On the Sherburne National Wildlife Refuge, Minnesota, we treated 662 ha (1638 acres) with 0.5 percent...
The role of bait manipulation in the delivery of oral rabies vaccine to skunks
Contributor(s):: Stacie J. Robinson, Susan M. Jojola, Kurt C. VerCauteren
The majority of rabies cases reported to the Centers for Disease Control each year occur in wildlife including skunks, raccoons, bats, foxes, and coyotes. Currently, oral rabies vaccination campaigns are employed to immunize coyotes, foxes, and raccoons. Though skunks are vectors of 6 rabies...
Estimation of red-winged blackbird mortality from toxic bait application
Contributor(s):: James F. Glahn, Michael L. Avery
Application of slow-acting toxic bait is one method of reducing local populations of depredating blackbirds. Estimating numbers of birds killed in such baiting operations is difficult because affected birds die off-site and are seldom recovered. We conducted bioassays and flight pen studies of...
Pindone for rabbit control: efficacy, residues and cost
Contributor(s):: Peter C. Nelson, Graham J. Hickling
Toxins are a major component of rabbit control campaigns in New Zealand, with sodium monofluoroacetate (1080) being the primary toxin in use since the 1950s. However, landowners can use 1080 only under the direct supervision of a licensed operator, and rabbit populations in regularly-poisoned...
Metoclopramide hydrochloride did not prevent 1080-induced vomiting in coyotes
Contributor(s):: Jeffrey S. Green
Vomiting is a characteristic, although undesirable effect when using Compound 1080 (sodium monofluoroacetate) as a method of predator control for coyotes. Compound 1080 meat baits with (treatment) and without (control) an antiemetic, metoclopramide hydrochloride (MH), were fed to captive coyotes...

Minimizing harm in possum control operations and experiments in New Zealand
Contributor(s):: Morris, M. C., Weaver, S. A.
Pest control operations and experimentation on sentient animals such as the brushtail possum can cause unnecessary and avoidable suffering in the animal subjects. Minimizing animal suffering is an animal welfare goal and can be used as a guide in the design and execution of animal experimentation...
