PROBLEM TO BE SOLVED: To increase a pest-repelling effect on diurnal pests in a pest attractant lighting system which irradiates attraction light for attracting pests and keeping the pests away from plant to a farm field.SOLUTION: The pest attractant lighting system 1 is equipped with a setting unit 2 for setting an optional time zone at night as an action time zone, pseudo sunlight source sections 3 for irradiating pseudo sunlight containing no wavelength component of 500-600 nm to the entire vinyl house H1 during the action time zone and attracting light source sections 4 for irradiating attraction light to a part in the vinyl house H1. The activity of diurnal pests B1 is activated during the night by pseudo sunlight irradiation at night, and the activated diurnal pests B1 can be attracted by the attraction light and kept away from plant P1. Thereby, the diurnal pests B1 can be aggressively protected. Furthermore, the pseudo sunlight does not contain the light in the wavelength range of 500-600 nm reflected from the plant P1, therefore, the diurnal pests B1 become difficult to visually identify the plant P1, as a result, the pest-repelling effect is further increased.COPYRIGHT: (C)2011,JPO&INPIT【課題】害虫を誘引して植物から遠ざけるための誘引光を圃場に照射する害虫誘引照明システムにおいて、昼行性害虫に対する防虫効果を向上させる。【解決手段】害虫誘引照明システム1は、夜間の任意の時間帯を動作時間帯として設定する設定部2と、上記動作時間帯に500~600nmの波長成分を含まない擬似太陽光をビニルハウスH1内全体に照射する擬似太陽光源部3と、上記動作時間帯に誘引光をビニルハウスH1内の一部に照射する誘引光源部4とを備える。夜間の擬似太陽光照射により夜間に昼行性害虫B1の活動を活発化させ、その活発化した昼行性害虫B1を誘引光により誘引して植物P1から遠ざけることができる。このため、昼行性害虫B1に対して積極的に防虫することができる。また、擬似太陽光は植物P1に反射される500~600nmの波長範囲の光を含ないので、昼行性害虫B1は植物P1を視認し難くなり、従って、防虫効果がさらに高まる。【選択図】図1
