PROBLEM TO BE SOLVED: To improve control effects on diurnal insect pests damaging flowers in a lighting system for insect pest attraction to irradiate a field with attraction light so as to attract insect pests and to keep the insect pests away from plants.SOLUTION: The lighting system 1 for insect pest attraction includes a setting part 2 for setting an arbitrary time zone at night as an action time zone, a light source part 3 of pseudo-sunlight and an attraction light source part 4. The light source part 3 of pseudo-sunlight irradiates the whole of the inside of a plastic greenhouse H1 with pseudo-sunlight not including a wavelength component of 400-500 nm in the action time zone and the attraction light source part 4 irradiates a part of the inside of the plastic greenhouse H1 with attraction light in the action time zone. Diurnal insect pests B1 are activated at night by irradiation with pseudo-sunlight at night, attracted by attraction light and kept away from plants P1. Since light at wavelength of 400-500 nm is blue light that the diurnal insect pests B1 damaging flowers like and the pseudo-sunlight does not include a component of the blue light, a reflection by the plants P1 does not include a blue light component, therefore, the diurnal insect pests B1 are hardly attracted to the plants P1.COPYRIGHT: (C)2012,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、花に加害する昼行性害虫に対する防除効果を向上させる。【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、擬似太陽光源部3及び誘引光源部4とを備える。擬似太陽光源部3は上記動作時間帯に、400~500nmの波長成分を含まない擬似太陽光をビニルハウスH1内全体に照射し、誘引光源部4は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。夜間の擬似太陽光照射により昼行性害虫B1は夜間に活発化し、誘引光により誘引され植物P1から遠ざかる。400~500nmの波長範囲の光は、花に加害する昼行性害虫B1が好む青色であり、擬似太陽光はその青色光の成分を含まないので、植物P1による反射光も青色光成分を含まず、従って、昼行性害虫B1が植物P1に誘引され難くなる。【選択図】図1
