THE dreadedtomato potato psyllid has been found in Western Australia.

Earlier today the Department of Agriculture and FoodWestern Australia reported that it is conducting surveillance in commercial crops and backyard gardens following the detection of the vegetable pest in the Perth area.

Department acting chief plant protection officer, Sonya Broughton, said officers were working with the horticulture industry to respond to the exotic plant pest, tomato potato psyllid (Bactericera cockerelli).

“A pest has been detected in a capsicum crop in a commercial property north of Perth, backyard tomatoes and eggplants in Belmont and backyard tomatoes at two properties in Mount Hawthorn and in chillies at a property in Palmyra,” Dr Broughton said.

“The department has quarantined the impacted properties to restrict the movement of vegetable and plant material off these properties.

“DNA barcoding results today have confirmed the presence of the pest. This is the first time the psyllid has been detected in Australia.”

This insect pest is a significant production pest in other countries where it is present, including the USA, Central America and New Zealand.

Tomato potato psyllid attacks a range of plants in the Solanaceae family including potato, tomato, eggplant, capsicum, chilli and tamarillo, along with sweet potato.

DETECTED: Tomato potato psyllid nymphs on the under side of a tomato leaf.

It’s another blow to the WA vegetable industry after cucumber green mottle mosaic virus (CGMMV) was discovered in a commercial cucumber crop in near Geraldton in July.

It has since been found in Carnarvon.

Dr Broughton said department officers were surveying properties within the wider metropolitan area to determine the location of the pest.

Commercial vegetable producers and backyard growers are urged to check for signs of the psyllid and report any unusual detections to the department’s MyPestGuide Reporter app.

Reporting options are also available from mypestguide.agric.wa.gov419论坛 or by contacting the department’s Pest and Disease Information Service [email protected]论坛 or 1800 084 881.

“Tomato potato psyllid is a tiny sap-sucking insect. Adult psyllids resemble small winged aphids in appearance and are about 3mm long,” Dr Broughton said.

“The body is brownish and has white or yellowish markings on the thorax and a broad white band on the abdomen. Its wings are transparent and held vertically over the body.

“Symptoms of damage on plants can include stunting, yellowing and purpling of leaves, distorted leaf growth and stem death.

“Growers who suspect the pest is on their property are advised not to spray for the pest or disturb plants until their crops have been surveyed and an appropriate treatment has been identified.”

The tomato potato psyllid can carry the bacterium “Candidatus Liberibacter solanacearum”, causing the ‘zebra chip’ disease in potato. The bacterium has not been found in any samples taken to date.

VegetablesWA CEO John Shannon said WA’s horticulture industry was critically important to the State’s economy.

“We have access to international expertise which will help us to best respond to this new pest and we will be work closely with the department to share this expertise with growers,” Mr Shannon said.

Music breaks stigma

By |

TALENT: Paul Corfiatis in his home studio at Montello where he composes original music.
Nanjing Night Net

Paul Corfiatis is a gifted music composer on a mission to break the stereotype of people with autism.

The 35-year-old Montello resident composes music on a computer at his home studio.

His work has been played at stage shows and his goal is to spread his sound across the nation and then the world.

“I want people to hear my music because I think it’s unique,” he said.

“It’s about creating a unique sound and making something original for people to enjoy.”

While Paul is on the spectrum he does not like to be seen as an autistic person.

“Ijust want to be seen as a normal person,” he said.

“I think a lot of people just see me as a talented composer.

“Some people might think he’s got autism, he’s amazing –maybe they think autistic people are dumb but actually a lot of autistic people are very smart.”

Paul will perform at Prism in Rosny Farm on April 2.

Prism will be a celebration of the diverse talents of autism.

The aim is toshowcase what is possible, inspire and motivate young people on the autism spectrum and build a new awareness of autism in the community.

Paul has been composing music since about 1998 after taking an interest in the expanding digital horizons.

“I knew as Igrew up the technology would get better and computers would get faster,” he added.

He started out only wantingtowrite files for computer games.

“I thought Icould expand this further and in 2001 Iwent into a recording studio and started to learn how to do mixing and sampling and all that stuff,” he said.

For 17years he has composed a variety of music from techno, trance, psychedelic and ambient genres.

With the North-West Coast’s arts and social change company,Big hART, Paul’s music has been played across the region.

His composing skills have been refined and now Paul is aiming high.

“My goal is to start playing my original music live and hopefully I can expand that maybe around Australia and then the world,” he said.

“We need more original artists, especially electronic artists, here in Tasmania.”

It is Paul’s goal to find the right forum to play his music on the North-West Coast andthrough his skills, Paul will continue to challenge the autism stereotype.

Liberals support solar thermal power

By |

ENERGY: State Shadow Energy Minister Dan van Holst Pellekaan says the SA Liberal energy policy will not kill off a solar thermal power plant in Port Augusta..The South Australian Liberal Party’s plan to scrap South Australia’s Renewable Energy Target (RET)will not scare away solar thermal power investors from a development in Port Augusta, according to state Shadow Energy Minister Dan van Holst Pellekaan.
Nanjing Night Net

It follows state Opposition Leader Steven Marshall’s calls on Monday February 13 which promised to, “abolish Labor’s dangerous plan to rapidly increase the volume of unreliable and intermittent renewable energy in South Australia.”

“Until there are viable storage options for intermittent renewable energy, South Australia must reject the Weatherill Labor Government’s dangerous target of 50 per cent,” he said.

Repower Port Augusta Campaigner Dan Spencer said this move will create ‘more uncertaintyfor investors’.

“This fresh policy uncertainty risks turning away investment in solutions like solar thermal in Port Augusta which the South Australian Liberals have advocated for and other renewable storage” Mr Spencer said.

“We want to see the South Australian Liberals announce their plans to support the next generation of clean power with storage like solar thermal in Port Augusta. Disappointingly today’s attack was more politics than solutions.”

In a letter to state Energy Minister Tom Koutsantonis on Friday February 10, Mr van Holst Pellekaan said any major and innovative plan to address South Australia’s ‘extremely serious energy problems’ must include a solar thermal power station at Port Augusta.

“Renewable energy with dispatchable storage must be part of the solution,” the lettersaid.

“ …The tender to supply the state government’s own electricity demand (484GWH/yr) is an extremely good fit with a new solar thermal generator (110 Megawatt capacity) as it would be both a new generator and a renewable generator as requested by the government.”

The tender applications closed on January 6, 2017, with the winner expected to be announced by mid-year 2017.

In the letter Mr van Holst Pellekaan asked Mr Koutsantonis to consider extendingthe tender’s time frame from 10 yearsto 20 years to allow a proponent to attract finance.

Mr Koutsantonis said, “the Department advised that a 10 year contract was sufficient to incentivise investment in new electricity generation.”

He said the assessment panel is independent of government and will make recommendations to cabinet before the results of the tender are announced, and criticised Mr van Holst Pellekaan.

“The tender is technology agnostic and aims to bring additional generation into the market that is despatchable around the clock. This will put downward pressure on power prices in South Australia,” he said.

“Mr Pellekaan’s policy to scrap the RETand allow a federal government that hates renewables to dictate South Australian policy would kill any prospect of solar thermal development in Port Augusta.”

South Australia’s RETis 50 per cent by 2025 and renewbale energy currently accounts formore than 40 per cent of the state’senergy mix.

Mr Koutsantonis said SA’sRETis aspirational, “which means there is nomechanism or incentive in place to drive the uptake of renewables.”

Mr van Holst Pellekaan said scrapping that state RETgives‘greater certainty’ to potential investors of renewable energy storage projects and said Mr Koutsantonis is‘100 per-cent wrong’ on this issue.

“The reality is our policy does not include the federal government dictating what the Renewable Energy Target would be,” he said.

“Our policy is that the federal government and states jointly would determine a national target.”

Research finds healthy vision lies in great outdoors

By |

Outside benefits: Researchers have found that play time outside is beneficial for children’s health – including their eyesight.How often do your children play outside?
Nanjing Night Net

I would not be surprised if you said it was not very often given the heat wave we are having and the well-known effects of too much sun.

However it is important that children have time outside each day.

There are lots of benefits of all kinds to be gained from spending time outside regularly.

Research shows that children who engage in outdoor play are healthier, and the opportunities for large body movements offered outside (running, jumping, playing on the trampoline etc) contribute to better body shape and body image, and help improve children’s sleep.

Outdoor play also offers opportunities for children to connect with nature and there is a lot of evidence now to show that connection with nature helps improve children’s health and wellbeing.

A recent study from the Queensland University of Technology introduced me to a new (to me) idea about the importance of outdoor play.

The studyshowed that twohours a day spent outside helps protect children’s eyes and helps prevent short-sightedness (myopia).

Myopia is the name for the condition where the lens in the eye does not focus the image onto the retina, rather it focuses the image in front of the retina. That means when looking at something in the distance, the image is blurry.

Children with myopia struggle to read what is written on the blackboard at school, and may not be able to read signs or recognise people when they are far enough away from them (I’ve spent my whole life worrying that people might think I am rude because I fail to recognise them when passing in the street!)

It has been predicted that within the next 30 years, nearly half of all the world’s population will have myopia.

Those of us who live in relatively affluent nations like Australia manage our myopia with glasses and/or contact lenses, although many parents struggle to cover the costs of providing these for their children, particularly when the glasses are lost or broken regularly.

However, there are many peoplein the world who do not have the financial resources to provide visual aids for their condition, and this can make a huge difference to children in school and in their lives outside of school.

The researchers from the Queensland University of Technology said their results showed that even for children who already have myopia, spending time outside every day can help slow the deterioration of their sight.

These QUT researchers are not alone in their conclusion – a large study from China has also indicated that increased myopia was associated with longer times spent indoors.

Clearly, we need to carefully create opportunities for children to play outside, juggling sun safe requirements with the need to expose children’s eyes not only to outdoor light but to the wide vistas the outdoor environment provides to stimulate our vision.

As long as our summer continues as it is, that juggle is going to be difficult but it is very important that we keep up our juggling act.
