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.

Why is it slow ?
1. high mountain range 2. 10 species in Korea : Native species have high ecological niche

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
