Termites a major threat to Victoria
Subterranean termites pose a major threat to dwellings and other vital infrastructure throughout Victoria according to a report released today by CSIRO Forestry and Forest Products (CFFP) scientist, Jim Creffield.
Mr Creffield says that in order to effectively manage the pest, all municipalities state-wide must immediately be ’termite declared’.
The report draws upon the expertise of the CSIRO Termite Group - comprised of ensis (a recently formed joint venture of CFFP and Forest Research, New Zealand) and CSIRO Entomology.
The annual cost of repair of damage to timber-in-service caused by termites in Victoria has been estimated to be in excess of $200 million.
Of the state’s 78 municipalities, 30 are not currently designated as being at risk of termite infestation of homes and other private and public structures. "However, no municipality in metropolitan Melbourne, for example, is devoid of infestation by termites," Mr Creffield says. He says redesignation of undeclared (unprotected) municipalities to ’declared’ status should be enacted through state legislation or individual council motion.
It is estimated that 650,000 Australian homes have been infested by termites over the last five years. The cost of treatment and repair of the resultant damage has been estimated at $3.9 billion. In undeclared areas, builders are not required to install termite management systems (TMS) during construction. "It is far more economical to have a TMS or barriers installed, than to incur damage and consequent restoration costs," Mr Creffield says. "Normal building insurance does not cover damage caused by termites - it is the responsibility of the owners."
Mr Creffield has over 30 years experience in the biology and control of termites and believes that regardless of the type of construction, without an adequate TMS termite infestation will almost certainly occur at some stage during the life of the structure.
A mature nest of termites can consist of over a million insects headed by a queen capable of laying up to 2000 eggs per day. Termites can feed on timber and timber products at up to 100m from their nests and can travel greater distances when provided with access to gaps, cracks, crevices or construction materials including pipes and cables. Termites will even attack electrical wiring cables, conduits and power points.
An infestation is often not detected until it is so severe that structural damage has occurred and substantial repairs and material replacement are required.

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
