The forests of Aquitaine, in south-west France, now play host to swarms of the the Asian Hornet, Vespa velutina, which is believed to have arrived there "from the Far East in a consignment of Chinese pottery in late 2004

 

Haxaire said he's now counted 85 "football-shaped" nests across the 40 miles which separate the towns of Marmande and Podensac "in the Lot et Garonne department where the hornets were first spotted".

 Asian hornets will station themselves hovering at about 30cm from the
entrance to the honey bee colony where they pounce on returning
bees that are carrying pollen, fall to the ground with them,
cut off the head with their mandibles and transport them to a tree.  Here they
remove the wings and legs before making a little “meat ball” that they transport
back to their nest to feed their own larvae

Having
found a colony, often a bee hive, they will sometimes arrive in
numbers to take an easy food source one after another. The consequences for the
bee colony can be catastrophic, if the flow of pollen into the
hive is severely disrupted. Over time it will result in the death of some or all
of the larvae and the queen will either stop or reduce
her egg production
. This will lead to the decline of the colony, ageing
bees will die with few or no replacements to take their place.  At best the
colony will be vulnerable to disease due to the dead larvae and the overall
weakness of the colony will lead to robbing. The colony will have little
hope
of over-wintering.

Solutions :

Small nests with only a
queen at the beginning of the season, can be destroyed using a powerful
aerosol wasp spray
with caution.

Larger nests should be
destroyed as a matter of urgency
by a competent person that is equipped
for the job. Your local pompiers may perform this
service, if not they will be able to give you the contact details of someone
that will.

Purpose-made traps as illustrated can be
placed anywhere where the Asian hornets are thought to be present and
importantly near to bee hives. The dimensions are very
important
.

Detection

11. To improve the likelihood of early detection government will continue to raise public, beekeeper and other stakeholder awareness about this pest through a species alert ID/Identification sheet issued in 2011 by the NNSS which requested the public to report sightings to them via alert_nonnative@ceh.ac.uk providing a photograph and details of location. The public are also invited to send a suspect sample to the NBU laboratory for examination. If the evidence supplied by the public or a beekeeper suggests that the pest is likely to be an Asian hornet, a NBU Bee Inspector will investigate the sighting. An ID sheet and Alert poster have also been prepared have been/will be distributed to all relevant stakeholders.


 
 
Materials you will need to make a trap
:

  • 1 x 2 Litre Plastic bottle
  • 1 x 100mm PVC joint (for 100mm PVC pipe)
  • 1 x 100mm PVC screw end cap for joint that will allow you to change the
    attractant without releasing any hornets
  • 1 piece of metal grill to put over the attractant.  This will prevent bees
    and insects falling in the liquid
  • 1 piece of wood 20cm x 20cm
  • Some steel wire, approx 60cm
  • PVC glue
  • Some silicone sealant

The diameter of the aperture prevents the European hornet
from entering – La taille de l’orifice ne permet pas à Vespa crabro de
pénétrer dans le piège


Capture space – Chambre de

Wire mesh grill (to prevent insects falling in the
attractant) – Grille de protection

5.5mm exit holes for other
species to escape. eg honey bees – 5.5mm trou de sortie pour les autres
espèces
