    Apologies C4u, you're absolutely right about the geography ... it was Portugal. However, whether or not they found adults, I think the description of the destruction visited on the apiary was correct. The absence of adults would mean that this wasn't really an "introduction" so the statement about once here, never removed, no longer needs qualifying.

    There was a consignment of queens from the US destroyed by the authorities in NI a few years ago as well. These were from Georgia, ie a SHB area. The beekeeper was let off with a slap on the wrist.

    The destination apiary was destroyed, yes. The ground around it was treated with insecticide, yes. Ploughed over? That bit is new to me. Also not clear is whether the queens ever reached the hives in question. The terms used in the description of the event was 'intercepted' in a consignment of illegally imported queens from Texas. That tends to imply they never reached the hives and that the destruction was a precaution in case this import route had been used before.

    At the time you could easily buy queens from a French vendor under the name 'Navatex'. They werte a primary importer from Weavers in Texas, and if you look up where they come from you will see how the name was derived. They sold them in their thousands to all parts of Europe, at a time when the USA was already a banned source, including to the UK. The same company also offered pure Caucasians from Georgia, and a range of specialist queens from the USA.

    More recently queens from Chile have been offered.

    I'll try and find the original review article ... it's around here somewhere.

    I don't think this was the original article, but it gives a good indication of what was done ...

    Key points ...

    1. it looks like the imports were legal as approval was obtained in advance from the National Veterinary Service (of Portugal)
    2. queens were transferred from original transport cages to introduction cages
    3. queens were introduced to nucs
    4. transport cages were inspected and found to contain 2 larvae
    5. all nucs/colonies in the two receiving apiaries were destroyed
    6. soil for 4 metres around the hives was removed and "deep buried"
    7. apiary ground was covered with plastic sheeting
    8. the apiary soil was soaked with permethrin
    9. the beekeeper was compensated for actual and predicted future losses


    Page 9 has got pics of the entire process ... the soil removal was done with a tractor, but with the front loader, so not 'ploughing' as such. Dates etc. are in the article, but the queens arrived on 17/9/04 and the permethrin soak was applied on 21/10/04.

    What we know from experimental work is that they *can* complete the pupal phase at temperatures which occur through much of the year in parts of Scotland and all year in parts of S England. We also know that they prefer damp soil rather than dry soil.

    These are the reasons for wanting to keep it out. It might be true that it will not thrive anywhere in the UK, but we don't know that is true.
    Living in the currently fairly frigid 'not Scotland' with a wet clay soil, my concern is that it's the perfect environment for SHB to thrive if it should arrive.

    This notification on the OIE website has just been drawn to my attention

    Surveillance of Aethina tumida in Italy in 2016

    Four new small hive beetle outbreaks have been detected in Calabria on 25th, 27th and 28th July 2016. They are roughly 100 km from the first protection zone established in Gioia Tauro in September 2014.

    The first outbreak in Cosenza was discovered in the framework of the surveillance for Aethina tumida carried out in the Calabria region in an apiary composed of 12 nuclei. Only Aethina tumida adults were observed. The epidemiological investigation carried out after the confirmation led to identify three other apiaries owned by the same beekeeper. Three of them were infested with adults and two of them also with larvae. All the outbreaks are within a 3 km radius. Ban of movements is enforced in a 10 km radius zone from the primary outbreak. The outbreaks are roughly 100 km from the first protection zone established in Gioia Tauro in Reggio Calabria province in September 2014 where all the outbreaks have been discovered so far. Clinical controls are being carried out in other apiaries in a 1 km radius zone from the primary outbreak with negative results so far. Epidemiological investigation is under way to ascertain the path of introduction in the primary outbreak.”

    This information has been disseminated by the World Animal Health information system (WAHIS): http://www.oie.int/wa…/public/wahid....report/Review…

    In all, six colonies out of the 128 present were found infested. All colonies of the apiaries were destroyed.

    On the new maps available from the Italian NRL on 15thJuly 2016, 35 apiaries have been inspected in Calabria and 376 in Sicilia (green dots). Nuclei (purple dots) were settled particularly in locations where apiaries had been previously found positive and destroyed. They aim at detecting the remaining presence of coleopterans in the environment.

    Two Aethina tumida adult specimens have been detected in in one sentinel apiary on 05th July 2016 located in the protection zone in the municipality of Candidoni in Calabria (purple cross). Adult and larva specimens have been previously detected in the apiary on 17th June 2016.

    To date, no SHB have been detected in Sicily in 2016.

    !Nothing about this on the official Italian website (IZS Venezie) or Beebase as yet, but I presume there will be shortly....

    Thanks, M. Great to have the latest news even if it is bad news, especially for the beekeepers in this new area.
