However, if this method is adopted, there is a concern that pests will be made resistant to chemical pesticides
In addition, when chemical pesticides are not properly applied to the area where the pests are present, the pests are not adequately repelled
In particular, in the case of spider mites, most of the spider mites exist on the underside of leaves, and it takes a lot of labor for the spreaders to spread chemical pesticides even in such a place.
Biopesticides mentioned as other repelling methods are difficult to select the time and place of application that can improve the effect, and because of the need for regular injection, the cost is high

Embodiment Construction
[0034] A lighting device for exterminating pests (hereinafter referred to as a lighting device) according to an embodiment of the present invention will be described with reference to the drawings. figure 1 The structure of the lighting device 1 of this embodiment is shown. The lighting device 1 includes: a lamp body 2 for irradiating ultraviolet rays to plants P; a dimmer 3 for dimming and controlling the lamp body 2 . The lighting device 1 is a device for irradiating ultraviolet rays to the plant P in order to repel the pest B1 parasitic on the plant P. As the pest B1 to be repelled, in particular, spider mites are assumed, and herbivorous insects and white butterflies are also assumed. tiny insects. Among the spider mites, there are included Tetranychus urticae, Tetranychus kamizawa, Tetranychus citrus, and the like.
[0035] The lamp body 2 has: a light source 21 for emitting light containing ultraviolet rays; a housing 22 for accommodating the light source 21 ; and a su...

The present invention relates to a lighting device for expelling pests, which can reliably exterminate pests such as spider mites. The lighting device for exterminating pests includes a light source and a control circuit for controlling lighting of the light source. The light source emits ultraviolet rays, and the ultraviolet rays include a wavelength of 260 to 305 nm, or have a peak wavelength in a wavelength range of 260 to 305 nm. The control circuit performs dimming control on the above-mentioned light source so that the radiation intensity of ultraviolet light emitted by the light source changes with time in the range of 0.1-50 μW / cm2, and the change is repeated. According to this, especially when the pests are spider mites, by irradiating the action of the spider mites at a low intensity, the movement of the spider mites is slowed down, and then by radiating ultraviolet rays at a high intensity, it is possible to use the spider mites without letting the spider mites go. The continuous irradiation of high-intensity ultraviolet rays to spider mites can kill spider mites. Thus, spider mites can be reliably repelled. Furthermore, the reliability of the insecticidal effect can be improved by repeating changes in the radiation intensity of ultraviolet rays.
Description
technical field [0001] The present invention relates to a lighting device for exterminating pests that irradiates plants with ultraviolet rays for exterminating pests. Background technique [0002] As a method of expelling pests parasitic on plants, a method of spraying chemical pesticides on plants is generally used. However, if this method is employed, there is a concern of imparting resistance to chemical pesticides to pests. In addition, when the chemical pesticides are not properly applied to the places where the pests are present, the repelling of the pests is insufficient. In particular, in the case of spider mites, most spider mites exist on the underside of leaves, and it takes a lot of labor for the spreaders to spread chemical pesticides even to such places. The biopesticides mentioned as other repelling methods are difficult to select the time and place of application that can improve the effect, and because they need to be injected regularly, the cost is high....
