Seven isolates of entomopathogenic fungi, Isaria fumosorosea (IFCF-H and IFCF-L), Beauveria bassiana s.l. (Bb02 and Bb04) and Metarhizium anisopliae s.l. (Ma01, SM076 and M09), were selected for their pathogenicity against Solenopsis invicta as well as feeding preference of S. invicta. When ants were treated with a conidial suspension at a concentration of 1×108 conidia/ml, the median lethal times (LT50) of IFCF-H, IFCF-L, Bb02, Bb04, Ma01, SM076 and M09 were 3.4, 162.6, 7.3, 2.8, 3.8, 7.3 and 2.7 d, respectively after 10 days. The median lethal concentrations (LC50) on the tenth day after inoculation were 1.20×107, 1.56×1010, 4.23×107, 3.04×106, 6.13×106, 2.90×107 and 9.90×105 conidia/ml, respectively. Furthermore, S. invicta consumed significantly less solution flavored with Bb04 conidia than the control, which was demonstrated by the lowest preference index (PREF = 0.09). S. invicta did not have a significant feeding preference for other fungal isolates. The pathogenicity (LC50) of fungal isolates was not significantly correlated (R2=0.013) with the PREF of S. invicta. However, in the paired choice experiments between different virulent isolates belonging to the same genera, S. invicta tended to select the solution flavored with conidia of relatively lower pathogenic isolates such as IFCF-L, Bb02 and SM076. We conclude that the pathogenicity of congeneric fungi may affect the feeding preference of S. invicta. Red imported fire ants might adjust their feeding response to entomopathogenic fungi based on the profile of microbial volatile organic compounds.

Invasive alien tramp ants are a diverse group of species originating from many regions of the globe which arrive at Australia's doorstep through a variety of transport pathways. They share genetic, behavioural, and ecological attributes that influence their probability of entry, establishment and spread, ecological dominance, and high impact.

While their impacts on biodiversity in Australia are not well quantified, many tramp ants have the ability to affect Australia's native biodiversity. Their impacts may be felt directly through predation upon or competition with native animals, or indirectly by modifying habitat structure and altering ecosystem processes. Most tramp ants have multi-sectoral impacts, and can affect plant and animal health, social and cultural values, and human health.

The effective and appropriate management of threats from tramp ants poses a formidable challenge to Australia, testing the continuum of biosecurity, from pre-border surveillance through to pest management. Individual tramp ant species are at varying stages in the invasion process, so the nature and scale of management responses will vary accordingly.

The tramp ant threat abatement plan 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 long-term survival of native species and ecological communities affected by tramp ants.

The goal of the plan is to minimise the impact of invasive tramp ants on biodiversity in Australia and its territories by protecting threatened native species and ecological communities, and preventing further species and ecological communities from becoming threatened.

The department hasn't established a specific implementation team for tramp ants. Initially there was the National Tramp Ant Committee (NTAC) which did have a wide mandate and occasionally assisted with elements of the TAP, but the NTAC has ceased and has been replaced by the Tramp ant consultative committee, which focuses on emergency responses to tramp ant issues.

Since the Red Imported Fire Ant Solenopsis invicta was found in late 2004 in Mainland China, researchers have paid much attention to this new invasive species. Here we summarise a series of studies on this serious invasive pest, including research on reproductive biology and ecology, ecosystem impacts, quarantine techniques, potential distribution and risk of spread, besides monitoring and management techniques. To date, S. invicta has been found in five provinces in South China and has the potential to spread further north, not only by natural dispersal but also by human transportation. The total S. invicta population increases greatly in spring and autumn, and causes serious ecological impacts because of its high population density in South China. Besides quarantine techniques intended to prevent the fire ant from further dispersal, chemical control has been the main management method until a more effective biological control agent is found. In some areas control strategies have achieved promising results.
