◾ Vespa velutina nigrithoax Buysson, 1905
Asian Hornet
Yellow-legged Asian Hornet
Asian black hornet
◾ Korean common name: Black thorax wasp
Social problem
“Honeybee Killer” or “Killing wasp” ◾ People
Killing V.v fire fighter died by V.v
◾ Beekeeping industry
It damages about $144,000,000
◾ Natural ecosystem disturbance
Dominant species chage: V.crabro, V s. simillima V.v
2003
2004
Southern China
V.v was introduced to have Korea from southern China in 2003
The influx of wasps is estimated to be caused by traders such as wood.
V.v was first discovered near Busan Port in 2003.
Busan port
First discovered
3.5km
V.v nest when first discovered First discover area in Busan
The beekeeper has been inquiring that the new wasp damages the honeybee In Busan, 2008 In 2009, study on wasp control began for apiculture industry Korea common name: Black wasp
2016 First reported region
2016 2014
: Regions reported before 2012 : 2014 confirmed region
Why is it slow ?
1. high mountain range 2. 10 species in Korea : Native species have high ecological niche
Korea France

Year of Invasion
2003 2004
Speed(km/yr) 12.4±6.77 < 67.3±25.43
Max Speed(km/yr)
26.4 < 154.5
The spread speed coefficient
increases by time.
Estimating Economic Damage
1) Labor force used for wasp control During for Control
: 40,000 beekeeper x $50 x 100/2days
$10,000,000
2) Colony loss 30 % loss $ 7,500,00
Economic damage
$ 17,500,000
1. Bite trap oak tree + sugar + fruit + juice + wine
2. Contact pesticide
3. Direct killing
Increased damage
