Threat abatement plan to reduce the impacts of tramp ants on biodiversity in Australia and its territories establishes a national framework to guide and coordinate Australia’s response to tramp ants, identifying the research, management, and other actions necessary to ensure the longterm survival of native species and ecological communities affected by tramp ants. It identifies six national priority species as an initial, but flexible, list on which to focus attention. They are the red imported fire ant (Solenopsis invicta), tropical fi re ant (S. geminata), little fire ant (Wasmannia auropunctata), African big-headed ant (Pheidole megacephala), yellow crazy ant (Anoplolepis gracilipes), and Argentine ant (Linepithema humile) (Commonwealth of Australia. 2006a).
The background document to the Threat abatement plan to reduce the impacts of tramp ants on biodiversity in Australia and its territories provides supporting information on a range of issues such as tramp ant biology, population dynamics, spread, biodiversity impacts and management measures (Commonwealth of Australia. 2006b).
Kakadu National Park
P. megacephala was eradicated from Kakadu National Park in northern Australia using
broadcast applications of Amdro at 2.5 kg/ha (Hoffmann & O'Conner, 2004 in Warner et al., 2008).
It has been reported that one application of Amdro on Moku‘auia islet off O‘ahu successfully eradicated P. megacephala (Krushelnycky et al., 2005 in Wetterer, 2007).
The aim of the Invasive ant pest risk assessment project was to assess the threat to New Zealand of a wide range of ant species not already established in New Zealand and identify those worthy of more detailed assessment. A Preliminary invasive ant risk assessment was conducted and a risk assessment scorecard was developed to quantify the threat to New Zealand of a range of ant species, and aid selection of those worthy of more detailed assessment. 75 taxa were scored and grouped into high, medium, or low threats. A summary was prepared for each taxa, outlining why it was considered for assessment, and the mitigating factors that affect its risk to New Zealand. Please see Ranking for more details.
As part of the pest risk assessments, the threat each ant posed to New Zealand was considered in terms of: likelihood of entry; likelihood of establishment; likelihood of spread; and the detrimental consequences of its presence in New Zealand. The scores are compared with two species already established in New Zealand, Linepithema humile (a relatively widespread and abundant pest) and Pheidole megacephala (restricted in distribution and not currently considered a significant pest). Comparison was also made to Solenopsis invicta, which is widely recognized as a significant threat to New Zealand and other countries in Oceania and for which a risk assessment had already been conducted before this project.
Each pest risk assessment contains information under the following sections: Pest information; Likelihood of entry; Likelihood of establishment; Likelihood of spread after establishment; The environmental, human health and economic consequences of introduction; Likelihood and consequences analysis.
Key points that have been drawn from the risk assessment of by the authors are: "S. invicta has a similar score to Linepithema humile, which is already established in New Zealand and is a significant pest. Unlike S. invicta, L. humile does not have medical consequences associated with its presence, but S. invicta is likely to have a more restricted distribution and it is uncertain where it will establish and become abundant".
Please see Information sheet for more details of this species.
Systematic chemical eradication using hydramethylnon in Jabiru commenced 2002, nothing elsewhere.
Tanzania, United Republic of
Control of P. megacephala was achieved for about 5 months using Amdro bait in a coconut plantation in Zanzibar (Zerhusen & Rashid, 1992 in Warner et al., 2008)

Résumé: AntWeb illustrates ant diversity by providing information and high quality color images of many of the approximately 10,000 known species of ants. AntWeb currently focusses on the species of the Nearctic and Malagasy biogeographic regions, and the ant genera of the world. Over time, the site is expected to grow to describe every species of ant known. AntWeb provides the following tools: Search tools, Regional Lists, in-depth information, Ant Image comparision tool PDF field guides maps on AntWeb and Google Earth and Ant genera of the world slide show.

Series of unpublished Landcare Research contract reports to Biosecurity New Zealand. BAH/35/2004-1.
Résumé: The invasive ant risk assessment project, prepared for Biosecurity New Zealand by Landcare Research, synthesises information on the ant species that occur in New Zealand (native and introduced species), and on invasive ants that pose a potential threat to New Zealand.
There is a great deal of information in this risk assessment on invasive ant species that is of global interest, including; biology, distribution, pest status, control technologies.
The assessment project has five sections.1) The Ants of New Zealand: information sheets on all native and introduced ants established in New Zealand
2) Preliminary invasive ant risk assessment: risk scorecard to quantify the threat to New Zealand of 75 ant species.
3) Information sheets on invasive ant threats: information sheets on all ant species scored as medium to high risk (n = 39).
4) Pest risk assessment: A detailed pest risk assessment for the eight species ranked as having the highest potential risk to New Zealand (Anoplolepis gracilipes, Lasius neglectus, Monomorium destructor, Paratrechina longicornis, Solenopsis geminata, Solenopsis richteri, Tapinoma melanocephalum, Wasmannia auropunctata)
5) Ranking of high risk species: ranking of the eight highest risk ant species in terms of the risks of entry, establishment, spread, and detrimental consequences.
NB. The red imported fire ant (Solenopsis invicta) is considered to be the worst ant pest in the world. However, Solenopsis invicta was specifically excluded from consideration in this risk assessment as this species has already been subject to detailed consideration by Biosecurity New Zealand
(This invasive ant pest risk assessment was funded by Biosecurity New Zealand and Foundation for Research, Science and Technology. Undertaken by Landcare Research in collaboration with Victoria University of Wellington and Otago Museum)
