Abstract

In an insect pest attraction lighting system which irradiates a field with attraction light for attracting insect pests to keep the insect pests away from a plant, an effect of protection against diurnal insect pests is improved. An insect pest attraction lighting system 1 includes: a setting unit 2 which sets, as an operating time zone, an arbitrary time zone during nighttime; an artificial sunlight source unit 3 which irradiates the entirety of an interior of a plastic greenhouse H1 with artificial sunlight which does not include wavelength components of 500 to 600 nm, in the operating time zone; and an attraction light source unit 4 which irradiates a portion of the interior of the plastic greenhouse H1 with attraction light in the operating time zone. The irradiation of the artificial sunlight during nighttime increases the activity of diurnal insect pests B1, and the attraction light attracts the activity-increased diurnal insect pests B1, whereby the activity-increased diurnal insect pests B1 can be kept away from plants P1. Thus, protection against the diurnal insect pests B1 can positively be provided. In addition, since the artificial sunlight does not include light in a wavelength range of 500 to 600 nm which is reflected by the plants P1, it is made difficult for the diurnal insect pests B1 to visually recognize the plants P1, and therefore, an effect of protection against insects is enhanced further.

Claims

1. An insect pest attraction lighting method for irradiating a field with attraction light for attracting insect pests to keep the insect pests away from a plant, the insect pest attraction lighting method comprising:
