< Topic > As for the former bee birdhouse the blow hole chip had caused the generation of reservoir sumushi to the sabot, it had left to the defense capacity of the bee and vis-a-vis the invasion of the step foot insect, the capture vessel was installed and/or and vis-a-vis the fly insect or measure such that the nest gate is made narrow was taken. Solutions This invention to be inclined, the sabot for the bee birdhouse directing to the nest gate, because the blow hole chip is discharged to the outside automatically, the blow hole chip does not accumulate and it is cleaning unnecessary, and be able to cut off the invasion of the step foot insect with the hanging bell condition barrel of the perspective body, the fly insect fishes in the sky because the opening has been attached to a state where it goes down is difficult to invade in the lowest section of the approximately center part of the sabot for the bee birdhouse and, with this the former way there is no damage of the damage enemy almost, necessity of inspection of the birdhouse was gone frequently. < Choice figure > Drawing 2【課題】 従来のミツバチ巣箱は巣屑が底板に溜まりスムシの発生を招いていた、そして歩足昆虫の侵入に対してもミツバチの防御能力に任せていた、又飛翔昆虫に対しても捕獲器を取り付けたり又は巣門を狭くするなどの対策を取っていた。【解決手段】 本発明は、ミツバチ巣箱用底板が巣門に向けて傾斜しており自動的に巣屑が屋外に放出されるので巣屑が溜まらず掃除不要である、又歩足昆虫の侵入は透視体の釣鐘状筒体によって遮断でき、飛翔昆虫はミツバチ巣箱用底板の略中央部分の最下部に空中に釣り下がった状態に開口部が付いているため侵入し難い、これによって従来のように害敵の被害が殆ど無く、頻繁に巣箱の点検の必要がなくなった。【選択図】 図2
