<First Embodiment>
First, the first embodiment will be described. Fig.1 (a) (b) shows the structure of the light attracting insect trap system which concerns on 1st Embodiment. In order to prevent damage to the crop 11 in the field 10 by flying pests such as insects, the light attracting and catching insect system 1 attracts and captures the flying pests in the field 2 with light.

  The light-attracting insect trap system 1 includes one light-attracting trap 2 that attracts flying insects by light and traps them, and two auxiliary light sources 3a and 3b that assist in attracting the flying insect to the light-attracting trap 2 I have. In the present embodiment, the field 10 to which the light attracting insect capturing system 1 is applied has a substantially rectangular shape.

  The light attracting insect trap 2 includes an attracting light source 21 that emits attracting light for attracting flying pests, a reflector 22 that reflects the attracting light emitted from the attracting light source 21, and a catching container 23 that captures the flying pests. , Equipped with an electric striker (not shown) that ignites flying pests approaching the attracting light source 21, and is installed at an end in the field 10.

  The attracting light source 21 emits light having a peak of a light wavelength component at a wavelength of 300 to 400 nm, as in the past (see FIG. 13), as attracting light for attracting flying pests. The reflecting plate 22 reflects the attracting light emitted from the attracting light source 21 toward the center side of the field 10. The insect catching container 23 is provided at a position where the flying insect pest is dropped by an electric shock. An adhesive paper or adhesive liquid is provided in the insect trapping container 23 so that the flying flying pests cannot escape.

  The light attracting insect trap 2 having such a configuration irradiates the attracting light for attracting the flying pests from the end in the field 10 toward the central side by the direct light from the attracting light source 21 and the reflected light from the reflecting plate 22. As a result, the flying pests in the field 10 are attracted to the attracting light source 21. Then, the flying pest approaching the attracting light source 21 is lighted by an electric shocking device, and the falling flying pest is captured by the insect capturing container 23.

  Each of the auxiliary light sources 3a and 3b has a light wavelength component having the same wavelength of 300 to 400 nm as the attraction light emitted from the attraction light source 21 as the attraction auxiliary light for assisting the attraction of flying pests to the light attraction trap 2. Light weaker than the attracting light emitted by the attracting light source 21 is emitted. The attracting auxiliary light emitted from the auxiliary light sources 3a and 3b only needs to include a light wavelength component having a wavelength of 300 to 400 nm, and does not need to have a peak of the light wavelength component at a wavelength of 300 to 400 nm. The radiation output (light emission intensity) of the auxiliary light sources 3a and 3b is preferably 1/30 to 1/2 of that of the attracting light source 21, and the auxiliary light sources 3a and 3b have a low wattage. The ultraviolet lamp and ultraviolet LED of (w) can be used.

  The auxiliary light source 3a is installed at the height of Ha, and the auxiliary light source 3b is installed at the height of Hb. The auxiliary light sources 3 a and 3 b are both installed above the crop 11 in the field 10 and within the irradiation range of the attracting light by the attracting light source 21. The auxiliary light sources 3a and 3b are both installed at a position higher than the installation height Ho of the attracting light source 21 (Ha, Hb> Ho), and the installation height Ha of the auxiliary light source 3a and the installation of the auxiliary light source 3b. The height Hb is substantially the same.

  Further, in the auxiliary light source 3a and the auxiliary light source 3b, the auxiliary light source 3a is installed closer to the attracting light source 21. The auxiliary light source 3a closer to the attracting light source 21 is preferably installed within a range where the distance La from the attracting light source 21 is approximately 5 to 10 m and the attracting light from the attracting light source 21 is irradiated. The auxiliary light source 3b farther from 21 is preferably installed in a range where the distance Lb from the auxiliary light source 3a is approximately 5 to 10 m and the attracting auxiliary light from the auxiliary light source 3a is irradiated. The auxiliary light sources 3a and 3b are installed between the troughs 12.

  The light attracting insect trap system 1 is in a state where the attracting light source 21 of the light attracting insect trap 2 and the auxiliary light sources 3a and 3b are always lit during the operation for attracting and capturing the flying pests.

  According to the light-attracting insect trap system 1 having such a configuration, even if there is a place where the attracting light from the attracting light source 21 of the light-attracting insect trap 2 is not irradiated, for example, in the shade of the crop 11, the place is supplemented. Attraction assist light from the light sources 3a and 3b can be irradiated. Thereby, the flying pest in a place where the attracting light from the attracting light source 21 is not irradiated is attracted to the auxiliary light sources 3a and 3b by the attracting assist light from the auxiliary light sources 3a and 3b. The auxiliary light sources 3a and 3b are installed within the irradiation range of the attracting light from the attracting light source 21, and since the radiation output of the auxiliary light sources 3a and 3b is weak in the radiation output of the attracting light source 21, the auxiliary light sources 3a and 3b The flying pest attracted to 3b is further attracted to the attracting light source 21 by the strong attracting light from the attracting light source 21, and is captured by the light attracting insect trap 2.

  Thus, according to the light attracting insect capturing system 1, the flying light pests can be actively attracted, fixed and guided to the attracting light source 21 by the auxiliary light sources 3a and 3b, without installing the auxiliary light sources 3a and 3b. Compared with the case where one light attracting insect trap 2 is installed alone, the flying pests in the field 10 can be attracted and captured efficiently.

  Moreover, by making the radiation output of the auxiliary light sources 3a, 3b 1/30 to 1/2 of the attracting light source 21, the flying light pests can be effectively attracted from the auxiliary light sources 3a, 3b to the attracting light source 21 and attracted. It is possible to prevent the flying pest from reversing from the light source 21 to the auxiliary light sources 3a and 3b, and to attract and capture the flying pest more efficiently. In addition, by placing the auxiliary light source 3a closer to the attracting light source 21 in a range of a distance La from the attracting light source 21 of about 5 to 10 m, the flying light pest is attracted from the auxiliary light source 3a to the attracting light source 21 more effectively. In addition, it is possible to more effectively prevent the flying pest from reversing from the attracting light source 21 to the auxiliary light source 3a, and the flying pest can be attracted and captured more efficiently. Furthermore, by making the installation heights Ha and Hb of the auxiliary light sources 3a and 3b higher than the installation height Ho of the attracting light source 21, it is possible to attract the flying pests to the attracting light source more effectively and attract the flying pests more efficiently. I can capture it.

  An embodiment of the light-attracting insect trap system 1 having such a configuration will be described below. A light attracting insect trap 2 having a radiation output of 20 w of the attracting light source 21 is used, and an ultraviolet lamp of 5 w (1/4 radiation output of the attracting light source 21) is used for each of the auxiliary light sources 3a and 3b. Is installed at the end of the field 10 as in the above embodiment, the installation height Ho of the attracting light source 21 is 1 m, the installation height Ha of the auxiliary light source 3a is 2.5 m, and the installation height Hb of the auxiliary light source 3b is = The light attracting insect capturing system 1 was carried out with 2.5 m, the distance La = 5 m from the attracting light source 21 to the auxiliary light source 3a, and the distance Lb = 8 m from the auxiliary light source 3a to the auxiliary light source 3b.

  As a result, when only one light attracting insect trap 2 (the radiation output of the attracting light source 21 is 20 w) without installing the auxiliary light sources 3a and 3b, only 219 flying pests could be captured. In contrast, in this example, 890 flying pests could be captured. As described above, in this embodiment, the effect of attracting and capturing flying pests in the field 10 is significantly greater than when only one light attracting insect trap 2 is installed without installing the auxiliary light sources 3a and 3b. Improved.
