PROBLEM TO BE SOLVED: To provide insecticidal facilities and an insecticidal method which can easily kill insect pests infesting plants only by injecting total amount of carbon dioxide gas without using chemical agrochemical and a complicated control device.SOLUTION: In the insecticidal method, an insecticidal bag 1 which is composed of a bag or a container made of material blocking carbon dioxide gas, has an inner gas circulation fan 4, and comprises a carbon dioxide gas injection part 6, is used. The method kills insect pests for a prescribed time by injecting total amount of carbon dioxide gas of a carbon dioxide gas cylinder and a carbon dioxide gas mini gas cartridge 10 and homogenizing the concentration of carbon dioxide gas with an inner gas circulation fan 4 while keeping the concentration range of carbon dioxide gas and a prescribed temperature range.COPYRIGHT: (C)2016,JPO&INPIT【課題】植物についた害虫を化学農薬や複雑な制御装置を使用せず、炭酸ガスを全量注入することで簡単に殺虫することができる害虫殺虫用装置と殺虫方法を提供する。【解決手段】炭酸ガスを透過しない素材で作られた袋や容器からなり、内部ガス循環用ファン4を有し、炭酸ガス注入部6を設定した害虫殺虫バッグ1を使用し、炭酸ガスボンベや炭酸ガスミニガスカートリッジ10の炭酸ガスを全量注入し、内部ガス循環用ファン4を用いて炭酸ガス濃度を均一化し、所定炭酸ガス濃度範囲内かつ所定温度範囲内に保ったまま所定時間で殺虫する害虫殺虫方法。【選択図】図1
