I agree, much less hassle, surprised it has not become more popular, instead of just exporting/importing queens, just sell the whole colonies.Originally Posted by mbc

Harder to hide whole colonies in grey envelopes too, or carry them back in your pocket.
Mmm not happening then?
I note that Polish thread has been suspended - sorry about the stushie I caused. Threats to my favourite animal rather get my back up! Perhaps the latest info out of Eurioe might temper my action - I had read this quite edifying item in the Swiss Beekeeper mag., earlier No easy cure and the trapping procedures don't work well ! Situation hopeless!!
The Small Hive Beetle – What beekeepers need to know!
The SHB was initially discovered in September 2014, in southern Italy. This is no reason for panic, however it is a good reason to avoid importing bees! It is also important to find out as much as possible about the Natural History of the Beetle, which could soon reach Switzerland.
Benjamin Dainat and Jean-Daniel Charriere. Agroscope, Centre for Bee Research, National Reference Laboratory for Bee Diseases. Schwarzenburgstrasse 161, 3003 Bern- Liebefeld. Translated from the Schweizwerische Bienen Zeitung, issue 12/2014. PP 18 and 19. by A.E.McArthur MIL
The SHB Aethina tumida was discovered on the 5th September, 2014 in Calibria, in the harbour area of Rosarno. Since then multiple infestations have been located in bee colonies. The infected beehives were all burned. The ground in the immediate vicinity of the affected apiaries was treated with insecticide. The aim is to eliminate the Beetle as swiftly as possible. It is assumed that the Beetle if it becomes established will spread widely throughout Europe.
What is the Small Hive Beetle?
As its name implies – it is a beetle whose life cycle is dependent on honey bees and bumble bees. It can infest bee products especially drawn comb, as well as colonies of bees. The adult beetle is able to fly at least 10 km to find a new colony to infest. Its reproduction cycle is shown in Figure 1 and demonstrates that it is dependent on the bee, even although Aethina is able to feed and live on fruit. Its original habitat is the sub Saharan region of Africa. The globalisation of trade and beekeeping has allowed the beetle to spread to Australia, America and Canada and now to Europe.
Damage to the Bee Colony Small colonies are particularly vulnerable to the beetle. The honey comb is also vulnerable. The beetle lays her eggs in cracks and grooves in the hive and the larvae feed on pollen, brood and even honey. The honey in the combs can ferment due to the distribution of yeasts by the beetle. The SHB can also be a vector for AFB. In the advanced stage of infestation the colony can be weakened and the honey reserves can be totally inedible for both bees and humans. Very strong colonies are able to keep the beetle infestations in check and survive, however even such a colony cannot completely eliminate an infestation.
Prevention Measures
This acute problem demonstrates that even importing bees from neighbouring countries is dangerous. The risks from imports had already been recognised for AFB and EFB and this also applies for the SHB. The most important measure which can be taken regarding the SHB is to avoid importing bees! Every beekeeper who imports bees or bee products not only puts themselves at risk they endanger their whole region. Once the SHB is introduced its spread can be extremely rapid, as we have found to our cost already with Varroa
What can be done should the SHB enter Switzerland?
In order to inhibit spread it is important to cease migrating bees or moving bees and to ensure that no used equipment which can be occupied by the beetle is left lying around and not checked regularly. In cases of suspected infestation the incumbent Bee Inspectorate must be informed immediately and samples should be send to the Reference Laboratory in Liebefeld. The individual beekeeper must learn to practice the necessary biosecurity procedures habitually and intensely.
1 Small colonies which do not develop to more than 6 frames should be culled.
2 As soon as honey combs are filled and sealed they should be removed and centrifuged.
3 Only store a minimal amount of drawn comb and check this comb regularly for beetle activity.
4 Maintain a clean and tidy apiary, clean equipment, do not leave comb lying around especially sacrificial drone comb. Do not leave extracted honey comb out for the bees to clean.
The American collective experience demonstrates that it is important to eliminate weak colonies, since these are easily colonised by the beetle. This new parasite now forces us to maintain large powerful colonies of bees.
Nucleus formation and queen rearing takes on a much more important role in order to avoid importing bees.
Treatment against the SHB? Treatment using the presently available substances is not desirable, since the risk of residue buildup in the hive products is more than possible and the treatments could have a negative effect on colony heath and well being. Trapping is an alternative to chemotherapy. The present stage of trap design is inadequate to be fully effective against the beetle. However the present trap designs used in Australia and America are ideal for diagnosis and discovery of initial infestations.
A number of research studies have indicated that formic and acetic acid are effective against the larval and adult stages of the beetle in the comb.
How Great is the Danger? The discovery of the SHB in Italy is no cause for panic, it must however be taken very seriously. Especially important is the avoidance of importing either bees or second-hand beekeeping equipment. The best bee for any area is the local indigenous bee. This is must from now on!
Hi, well the feedback here in Germany I'm hearing is that it is here now, and it will very probably stay. It's spread may be slowed by natural features like the Alps, but will not be halted. There is a very long list of invasions of all sorts, few were stopped and not much is being done differently to raise any hope this time. A ban on all imports may well the UK's beekeepers only hope.

Hi Calum where are you hearing this from ? Worrying development if confirmed
HiHi Calum where are you hearing this from ? Worrying development if confirmed
this months beekeepers magazine observes that reports of the beetle are now so widespread it can be considered as established in Italy.
It is not hopeless (they say) that it my yet be erradicated.
Our local beekeeping Fachwart (local state expert) is not confident that Italy has the recources to deal with it. Also as the problem has not been kept under control in its first season so expect more spread as a result of colony movement (autumn and spring).
The beekeeping magazine says that strong colonies will be able to cope with this, when treated correctly (medicated), as is the case with varroa.
It will not be the end of beekeping, but it will be another big challange, and will put much more pressure on colony survival.
In colder climes the beatle may not be such a huge issue, as the number of breeding cycles will be reduced, so it my be possible to hold the pest in check.

On the 12th December the EU put in place a ban on the movement of the following items from the region of Calabria and Sicily until 31 May 2015:
(i)
honey bees;
(ii)
bumblebees;
(iii)
unprocessed apiculture by-products;
(iv)
beekeeping equipment;
(v)
comb honey intended for human consumption;

Well if it's already in Germany as Calum is saying then they're shutting the gate after the horse has bolted aren't they?
I read his post differently; more of, 'it's here to stay in continental Europe'.
