Vespa velutina: a new hornet
for Europe and Korea

• Before 2004: 22 Vespa species in Asia and only 2 in Europe
• Introduction from China (near Shanghai) to Korea and France
through horticultural trade.

Impact on honeybees

• Asian bees have developed an efficient defensive heat-balling behaviour

• European honeybees stop foraging when facing hawking hornets (bee carpet)
• Such paralysis behaviour can lead to bee colony’s death during winter

Impact on honeybees
ECOBEE project (INRA-CNRS South West of France since 2008):
a long-term bee colony monitoring in intensive agroecosystems
RISQAPI project (2013-2016): spatial relationships between use of
pesticides and risks of bee colony decline
Work task: Vespa velutina as stress factor:
- assess hornet impacts (as predator and bee colony disruptor)
in relation to bee colony health status
(624 records, 90 days, 54 apiaries, 118 hives)
- using BEEHAVE model of bee colony dynamics
(Becher et al 2014)
Colony can colapse :
- when beehives are already weakened before hornet attack
- when beehives react with strong paralysis behavior

Q
• Worker sighting: a colony at < 2 km from capture point (foraging distance)
• Sexual sighting: no proof of colony presence near the capture point
sexuals can fly over much longer distances (> 40 km)
