PROBLEM TO BE SOLVED: To provide a hot water pest control device having a novel structure, stabilizing a hot water tapping temperature to a setting temperature by suppressing operating/stopping frequency of heating means, thereby reducing stress on crops due to excessive heat and moisture, etc. of hot water, and advantageously exhibiting pest control effects on a pest damage.SOLUTION: A pest control device 10 comprises: storage means 20 including a hot water storage area 34 storing hot water and a water storage area 36 storing water, in which the hot water storage area 34 and the water storage area 36 are arranged so as to flow across hot water and water to each other and control means 22, based on a temperature difference between a setting temperature and the temperature of hot water, storing hot water only in the hot water storage area 34 in the storage means 20, storing hot water in the hot water storage area 34 as well as storing water in the water storage area 36, or flowing one of the hot water in the hot water storage area 34 and the water in the water storage area 36 across to the other, thereby controlling the hot water storage amount in the hot water storage area 34 and the water storage amount in the water storage area 36.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】加熱手段の発停回数を抑えることで、出湯温度を設定温度に安定化させて、温水の過剰な熱や湿度などに伴う農作物のストレスを軽減させつつ、病虫害の防除効果が有利に発揮される新規な構造の温水防除装置を提供する。【解決手段】温水防除装置10には、温水を貯留する温水貯留領域34と水を貯留する水貯留領域36とを備え、温水貯留領域34と水貯留領域36とは温水および水が相互に越流可能に配置されている貯留手段20や、設定温度と温水の温度との差に基づいて、貯留手段20において温水貯留領域34にだけ温水を貯留させたり、温水貯留領域34に温水を貯留させると共に水貯留領域36に水を貯留させたり、あるいは温水貯留領域34にある温水と水貯留領域36にある水との一方を他方に越流させたりすることで、温水貯留領域34の温水貯留量と水貯留領域36の水貯留量を制御する制御手段22が設けられている。【選択図】図1
