Honey bees are responsible for pollinating hundreds of thousands of hectares of crops,http://ginasbloomingfantasies.com/wp-image.php?catalog/product/Mens_Denver_Broncos_DeMarcus_Ware_Nike_Orange_Limited_Jersey, fruit trees,http://www.agrolangeland.dk/settings.php?633-Copa-America-2015-Fodboldtr%25C3%25B8jer/639-Ecuador-Fodboldtr%25C3%25B8jer, nuts and vegetables; a service worth between $4 billion and $6 billion to the country's agriculture and horticulture sector.
A spokeswoman for Plant Health Australia,http://verdensbedstenogensinde.dk/wp-feed.php?tag/fodbold-i-london/, which manages the national honey bee pest surveillance program,http://www.chamika-tours.de/wp-searches.php?trikots/gruppe-f/argentinien-trikot-2014/, said 20 remote hives had been successfully trialled around high-risk ports in Brisbane,http://rentasgastronomicas.com/wp-diff.php?mundial-alemania-c-4_7_31.html, Darwin, Weipa,http://www.saspilot.no/phpinfo.php?adidas-fotballdrakt-fc-chelsea-john-terry-26-langermet-3rd-bortedrakt-2014-2015-v-1037.html, Cairns and Gladstone.

The surveillance program, which is jointly funded by the horticultural and honey bee industry and the government,http://www.nidelv-hestesenter.no/back-compat.php?Barcelona-Tredje-Drakt-2013-2014-Xavi-Gi-Billig, also manages a network of sentinel bee hives at ports such as Port Botany. Bees in those hives are regularly examined for diseases or pests.
Landcare wants to raise enough money to place 378 hives around 42 ports. Each hive costs $800 to build and deliver.
Dave Alden,http://hellenicstudiescsus.com/wp-atom.php?angola/, a senior program manager at the Rural Industries Research and Development Corporation,http://michaelzeki.com/wp-feed.php?guide-en-dag-i-qpr-land/, said the new hives were more efficient because they only required a person to check them when bees had been trapped inside.
Dr Alden said the consensus among research scientists was that varroa would arrive in Australia at some point.
But the longer we can keep it out the better,http://www.bucapositano.it/css.asp?chemlea-c-44_99.html, he said.
While a good surveillance system boosted the chance that pests would be intercepted,http://klassiksportwagen.de/plugins.php?Afrika/, nothing was foolproof.
Australia is the last continent to be varroa free. That's testament to the fact that surveillance has been working,http://cabincrewcertificate.co.uk/wp-links.php?replica-iwc-da-vinci-watches-outlet.htm, he said.
