PROBLEM TO BE SOLVED: To provide a device which keeps an Asian giant hornet from a hive gate so that an European honey bee is protected from the attach of the Asian giant hornet, and keeps the European honey bee from battling against the Asian giant hornet.SOLUTION: Two metal gratings 2 are installed upright back and forth with an interval of 25-30 mm so that the Asian giant hornet cannot come closer by neither flying nor walking toward the hive gate. The respective gratings are connected to the positive and the negative of a battery 4 to be energized. Both a power distribution fence and a nest box are raised up to the fixed height with the fixed distance therebetween so that the European honey bee does not get outside of the device, and battle against the Asian giant hornet. The device is covered with a net 6 so that the Asia giant hornet cannot get in.COPYRIGHT: (C)2012,JPO&INPIT【課題】セイヨウミツバチをオオスズメバチの襲撃から護るためにオオスズメバチを巣門に近づけないようにすると同時にセイヨウミツバチをオオスズメバチに立ち向かわせないようにする装置を提供する。【解決手段】オオスズメバチが巣箱に飛んでも歩いても近づけないように、2枚の金属格子2を25~30ミリの間隔で前後に立てて装着し、それぞれを電池4の正負につなぎ通電する。また、セイヨウミツバチが装置の外に出てきてオオスズメバチに立ち向かわないように、通電柵と巣箱の両方を一定の高さに上げ、一定の距離を置く。側面からオオスズメバチが入れないように網6で覆う。【選択図】図1
