Tomato potato psyllid detection in Western Australia- what it means for TasmaniaTomato potato psyllid (Bactericera cockerelli) was detected in Western Australia at several properties near Perth, Western Australia, early February 2017. This is the first detection of this pest in Australia.Tomato Potato Psyllid (TPP) is a sap-sucking insect that feeds on many plants in the Solanaceae family which includes potato, tomato, capsicum, eggplant and tamarillo and some in the Convolvulaceae family such as sweet potato.Actions are being taken nationally in response to this detection and to minimise the risk of movement of the pest to other parts of Australia.Implications for TasmaniaIf this pest entered Tasmania it would have greatest significance for growers of potato, tomato, capsicum, eggplant and related crops both indoors and outdoors. It also has implications for the nursery industry. As part of a Tasmanian Institute of Agriculture project, a network of yellow sticky traps has operated in Tasmanian potato crops in recent years to obtain early warning should this pest enter Tasmania. The pest has not been detected in Tasmania. However commercial producers and backyard growers are asked to check their crops for signs of the psyllid. Biosecurity Tasmania’s Plant Diagnostic Services can identify suspect material free of charge. If you think the tomato potato psyllid may be present in your crop or backyard plants, you need to report this to Biosecurity Tasmania by phoning the Exotic Plant Pest Hotline on 1800 084 881.About tomato potato psyllidThe tomato potato psyllid causes injury to plants directly by its feeding. It can also transmit a bacterial disease known as zebra chip which poses an additional threat to important horticultural crops, particularly potatoes. Damage to crops is most severe when the insect vector and bacteria coincide. The bacterium has not been detected in Western Australia.The noticeable signs of the tomato potato psyllid include insects jumping from the foliage when disturbed, severe wilting of plants occurs when there are large numbers of psyllids feeding, yellowing of leaf margins and upward curling of the leaves, and honeydew and psyllid sugar make the plants sticky and they often appear dirty. Actions taken by Biosecurity Tasmania thus farImportation pathways for risk produce from Western Australia have been investigated by Biosecurity Tasmania. With some exceptions Tasmania does not receive risk produce directly from Western Australia reducing risk of movement into Tasmania. Where produce may enter, it is via South Australia or Victoria first and must meet those State’s emergency conditions thus buffering risk for Tasmania. Tasmania has had treatment requirements on a range of risk material should any pathway exist, hence mitigating risk. Additional requirements are not deemed necessary at this time.The Chief Plant Health Manager (Tasmania) has declared TPP a List A Pest under the Plant Quarantine Act 1997 enabling regulatory action to be taken if needed. He has also issued an Area Freedom certificate for TPP to support continued access. for Tasmanian produce being exported interstate. An industry information forum will be organised by Biosecurity Tasmania in the near future as additional information comes to hand.As a general reminder, all growers need to practise sound farm biosecurity to prevent the entry, establishment and spread of pests and diseases.

Invasive Animals CRC national release of new strain of Rabbit Haemorrhagic Disease Virus (RHDV1 K5) in Tasmania – 2017
To combat the threat of rabbits within Australia, the national release of a Korean strain of Rabbit Haemorrhagic Disease Virus, known as RHDV1 K5 will commence from the first week of March, 2017. Rabbit Haemorrhagic Disease Virus is also known as rabbit calicivirus.
The release of RHDV1 K5 comes after more than 10 years of testing through the Invasive Animals Cooperative Research Centre RHD Boost project and includes participation by over 600 community groups and land managers across Australia, including ten sites in Tasmania.
Biosecurity Tasmania will administer the RHDV1 K5 bait to the Tasmanian site land managers under permit requirements.
The release sites in Tasmania are:
Barrington, Binalong Bay, Bridgenorth, Falmouth, Jackeys Marsh, Railton and Rowella.
Cambridge, Hobart and Port Arthur.
As part of the project, the public is being urged to get involved by helping to track the spread of the virus through downloading the RabbitScan (FeralScan) smart phone app, where you can easily report evidence of disease to assist land managers across Australia understand the movement of the virus.
To report sightings of rabbits or evidence of disease in your region visit www.rabbitscan.org.au or download via the iTunes or GooglePlay stores through searching for 'FeralScan'.
Visit the PestSmart website for more details on the national release of RHDV1 K5.
RHDV1 K5 only affects European rabbits and is a naturally occurring variant of RHDV1 from Korea. RHDV1 K5 poses no risk to human health or other non-target species. However, domestic rabbits and farmed rabbits may be affected. It is recommended that domestic rabbit owners and commercial rabbit breeders consult their local veterinarian about vaccinations and provide additional protection against the virus by keeping rabbits inside or in insect-proof enclosures.
Later this year (likely to be between May and June 2017), Biosecurity Tasmania expect to undertake another release of Rabbit Haemorrhagic Disease Virus if conditions are favourable for effective release.
For further information on Rabbit Haemorrhagic Disease Virus, please contact Biosecurity Tasmania: Northern Tasmania: 03 6421 7635 and Southern Tasmania: 03 6165 3265.

Biosecurity Advisory 1/2017 - Russian wheat aphid found in Tasmania
Russian wheat aphid, a serious insect pest of wheat, barley and some other cereal crops has been detected in Tasmania near Cressy. It was first detected in Australia 13 May 2016 in South Australia and spread rapidly to Victoria and New South Wales. The National Management Group determined it was not technically feasible to eradicate the aphid for several reasons including its wide distribution soon after detection.It most likely spread to Tasmania on northerly airflows.
Russian wheat aphid, Diuraphis noxia, is a small green aphid whose feeding produces strong plant symptoms due to the injection of saliva into the plant. Symptoms include rolled leaves, chlorotic spots, leaf streaking, trapped awns giving a hooked appearance and stunted crop.These aphids spend their entire life on cereals and grasses. They survive only a few days without feeding on suitable plants. The hosts that are most severely affected are barley and wheat. Other primary hosts include durum wheat, field broom grass, Elymus sp. and jointed goatgrass. Secondary hosts allow the aphid to survive but not reproduce. These include cereal rye, triticale and various grasses such as oats, tall wheat grass and Indian rice grass.
The presence of the aphid is not an export quarantine issue. Russian wheat aphids are best adapted to the dry climate of the mainland Australian wheat belt and are not well adapted to the moist Tasmanian climate.Natural control by brown lacewings, ladybirds and hoverflies is likely to be strong in Tasmania.
What to do if you think you have found Russian wheat aphid
Plant Diagnostic Services in Biosecurity Tasmania (DPIPWE) will identify aphids suspected of being Russian wheat aphid free of charge. Specimens or images can be submitted to a DPIPWE entomologist call 1300 368 550 to be directed to an entomologist.Samples of plants bearing aphids should be secured in sealed double plastic bags along with some absorbent paper towel.

Biosecurity Advisory 29/2016 - Public comment invited on proposal to import Red Panda into Tasmania
The Wildlife Management Branch has received species profile to facilitate risk assessments for the potential import into Tasmania of; Red Panda (Ailurus fulgens) Public comments are invited by 20 January 2017 The Red panda (Ailurus fulgens) is a unique species that occurs in the Himalayas and southern China, ranging from western Nepal and into India, Bhutan, northern Myanmar and through to the Minshan Mountains and upper Min Valley of Sichuan Province in south-central China. . A typical Red panda averages approximately 100cm in length, with a body length of around 60cm and an average tail length of 40cm. Red pandas are quite light for their size and do not display any size sexual dimorphism with both males and females averaging 4-6kg in weight, both in captivity and the wild. The red panda is listed as ‘endangered’ on the International Union for Conservation of Nature (IUCN Red List) since its evaluation in 2015, and is continuing to decline due to habitat loss by deforestation and habitat fragmentation, which also increases vulnerability of the species to predators. The species profile and background information for the risk assessment process is available for viewing on the DPIPWE website at: http://dpipwe.tas.gov.au/wildlife-management/management-of-wildlife/wildlife-imports/species-profiles-for-comment/red-panda-(ailurus-fulgens)
