Title: Varoa found in Asian honeybee swarm on cargo ship at Sydney port.

Not good news, glad they found it though!

I'm glad they were able to destroy the hive before any bees made it to the mainland.

I seem to remember ... isn't there some sort of quarantine zone around north Queensland to prevent Apis Cerana from coming south? That one boat from Singapore nearly moved the quarantine line about 3000km south overnight.

Thanks for the report, Paul.

Jeanette, A. cerana has already gone south through the quarantine area in QLD.  We actually saw a queenless obs hive of them at the bee meeting last week, and some videos of how to destroy them and a talk from scientists about them.  I did learn a few things.  The best part though was a human demonstration of the waggle dance.

Neil,  we are just about the only country without varroa (except in an australian owned island or two).  I am guessing antarctica doesn't have very many varroa either.  However, A. cerana is a natural host to the mite and have superior hygenic abilities and are able to live with it.  So countries naturally hosting asian honeybees or other non mellifera species really wouldn't be affected.

Although these asians are able to cope better they are not desirable to have here correct?

They are harder to domesticate and produce less honey.

We have a tropical subspecies of A. cerana so there is a possibility they won't migrate all the way south; but that remains to be seen.

The introduction of the Varroa mite into Australia has the potential to badly affect existing apiaries. In 2007, the Australian honey industry estimated that honey bee products were worth about $80 million per year to the economy. However, this pales beside their estimate of pollination services - $3.8 billion per year.

I don't know how much of an impact the Varroa mite would have. Reports vary from increased hive management costs to complete destruction of apiaries.

I would love to see that!  :-D

Jeanette,

I think rawfind was referring to having asian bees here, which we do already.  There is no question of whether varroa is undesirable.  We will bounce back as other countries have but it will be a pain in the meantime.

And yes it was a good waggle dance.  Scientists are not always boring.

That destruction has happened nowhere. It makes much work to professional beekeepers and makes much losses of hives.

What varroa makes is that it kills quickly feral beehives, and Australia have those lots.

Varroa control is laborous in countries where colonies have not brood break.
