  However, the insect trapping device disclosed in Patent Document 1 increases the amount of ultraviolet rays on the adhesive paper by the reflector, so that the trapping efficiency of insects is increased, but the amount of ultraviolet rays irradiated around the device is reduced, so that the insect attracting efficiency is increased. Is low. Moreover, although the insect capture device shown by patent document 2 provided the transparent collision board, the capture efficiency of the insect in an adhesion trap goes up, but the reflecting plate itself was equipped with the structure for improving insect attractance etc. As a result, there was no significant difference in insect attracting efficiency compared to existing attractant trapping devices.

  The present invention solves the above-mentioned problem, and can attract insects effectively by irradiating insect light over a wide range, and also attracts insects that can efficiently capture the attracted insects. An object is to provide an apparatus.

  In order to solve the above problems, the invention of claim 1 is attracted by a light source that emits insect light that attracts flying insects, a reflector that reflects light from the light source, and light from the light source. An insect capturing device comprising: a capturing unit that captures insects, wherein the reflector has a total reflectance of about 50% or more and a diffusivity of about 30% or more with respect to light having a wavelength of about 340 to 380 nm. It is comprised so that it may become.

  According to a second aspect of the present invention, in the attracting insect capturing apparatus according to the first aspect, the reflection plate is configured such that a total reflectance for light having a wavelength of about 380 to 470 nm is about 50% or more. Is.

  According to a third aspect of the present invention, in the insect capturing device according to the first or second aspect, the capturing unit is provided at a position below the light source, and is configured by a member having the same reflection characteristics as the reflecting plate. It is what.

  According to a fourth aspect of the present invention, in the attracting insect capturing device according to any one of the first to third aspects, the diffusivity increases as the reflecting plate comes closer to the capturing portion. It is what.

  According to a fifth aspect of the present invention, in the attracting insect capturing apparatus according to any one of the first to fourth aspects, a transparent adhesive sheet is adhered to the surface of the capturing unit.

  According to the first aspect of the present invention, the light having a high attractant wavelength of about 340 to 380 nm can be diffusely reflected by the diffuse reflector and irradiated with a wide range of attractant light, so that the conventional diffusivity is low. Insects can be attracted more effectively than when a reflector is provided.

  According to the invention of claim 2, since light having a wavelength including visible light of 380 to 470 nm is reflected, more insects are attracted and the user can visually recognize the lighting of the light source.

  According to the invention of claim 3, since the capture part itself functions as a diffuse reflector, and the attracting property of the capture part is enhanced, the insect is attracted effectively, and the attracted insect is efficiently captured. Can do.

  According to the invention of claim 4, the diffuse reflection of light having a high insecticidal property is increased in the vicinity of the capture unit, and the insect is attracted to the vicinity of the capture unit, so that the attracted insect is easily captured in the capture unit.

  According to the invention of claim 5, due to the reflection spectral characteristics of the surface of the capture part by sticking the transparent adhesive sheet, the diffuse reflection of the highly attracting light in the capture part increases, and the insect attracted to the transparent adhesive sheet increases. Therefore, the attracted insect can be captured more efficiently.

  Hereinafter, the insect trapping apparatus according to the first embodiment of the present invention will be described with reference to FIGS. 1A and 1B, taking a wall-mounted insect trapping apparatus as an example. A wall-mounted insect capturing device 10 includes a device main body 1 fixed to a wall, a light source 2 that irradiates insect light that attracts flying insects, and a reflector 3 that reflects light from the light source 2. A capturing unit 4 for capturing insects attracted by the light emitted from the light source 2 is disposed below the light source 2.

  The device body 1 is a housing having an open front and bottom surface, and screws and bolts (not shown) for fixing the insect capturing device 10 to a wall surface are arranged on the back surface, and a power source and ballast (not shown). The electronic equipment required for lighting control of the light source 2 is provided. Further, as the material of the apparatus main body 1, for example, a metal material having sufficient strength and durability against wind and rain such as stainless steel SUS is used.

  The light source 2 is a light source capable of irradiating light having a wavelength of about 340 to 380 nm, and a general-purpose fluorescent lamp (UV-A lamp) for insect traps is used. In general, the visual acuity sensitivity with respect to the wavelength characteristics of nocturnal insects is approximately 240 to 580 nm, and light having a wavelength of approximately 360 nm is considered to have the highest insect attractivity. Therefore, the light source 2 used as the attracting light needs to be able to irradiate at least ultraviolet light having a wavelength of about 340 to 380 nm. Preferably, a light source capable of attracting more insects and capable of emitting purple-blue light on a longer wavelength side (380 to 470 nm) so that the user can visually recognize the lighting of the light source 2 is preferable. However, a light source that emits yellow light having a wavelength of 500 nm or more, particularly near 580 nm, is not preferable because it has insect repellent properties.

The reflector 3 is disposed so as to reflect the light emitted from the light source 2 toward the front opening of the apparatus main body 2. For example, an aluminum diffuse reflector, a Nisshin Steel stainless steel NSS431DP-2 diffuse reflector, or a multilayer diffuse reflector is used as the reflector 3. FIG. 2 shows the reflection spectral characteristics of these diffuse reflection plates and conventional reflection plates. In the same figure, A is the reflection spectral characteristic of the aluminum diffuse reflector used for the reflector 3, B is the reflective spectral characteristic of Nisshin Steel stainless steel NSS431DP-2 diffuse reflector, and C is the reflection of the multilayer diffuse reflector. Spectral characteristics, D is the reflective spectral characteristic of a stainless steel SUS-304 reflective plate, which is a conventional reflective plate, and E is the reflective spectral characteristic of a white melamine-coated reflective plate. The diffusive reflector used for the reflector 3 is configured such that the total reflectance for light having a wavelength of about 340 to 380 nm is about 50% or more, and preferably about 65% or more. On the other hand, the conventional reflector has a total reflectance of about 30% or less with respect to light having a wavelength of about 340 to 380 nm. That is, the reflection plate 3 of the present embodiment configured so that the total reflectance for light having a wavelength of about 340 to 380 nm is about 50% or more can efficiently reflect highly attracting light. The insect attracting efficiency can be improved as compared with the conventional reflector. In addition, the reflection plate 3 of the present embodiment is configured so that the total reflectance for light having a wavelength of about 380 to 470 nm is also about 50% or more, and the visible light irradiated from the light source 2 is totally reflected. More insects can be attracted, and the user can visually recognize the lighting of the light source 2. In addition to the diffuse reflectors shown in the above A to C, a UV reflective fine particle (BaSO ₃ ) -coated white reflector, an Rh (rhodium) plated diffuse reflector, or the like may be used.

  The reflector 3 is configured such that the diffusivity with respect to light having a wavelength of about 340 to 380 nm is about 30% or more. Here, the diffusivity is obtained by the following equation.

  Table 1 below shows the trapping ratio of insects in each reflector (Examples 1 to 8 and Comparative Example 1) in which the total reflectance is approximate but the diffusivity varies stepwise. Table 1 shows the average values of total reflectance and diffusivity with respect to light having a wavelength of about 340 to 380 nm. Moreover, the capture ratio in the reflectors of Examples 1 to 8 is represented by a comparison when the insect trapping amount in the reflector of 1.5% diffusivity shown in Comparative Example 1 is 100%.

  As is clear from Table 1, the reflectors (Examples 1 to 5) having a diffusivity of about 30% or more were 1.5 times or more than the reflectors (Comparative Example 1) having a diffusivity of 1.5%. In particular, the reflectors (Examples 1 to 3) having a diffusivity of about 50% or more showed a capture ratio of about twice. The above results show that a reflector with low diffusivity reflects light only in a specific direction, so the light irradiation area is narrow, but a diffuse reflector with high diffusivity diffuses and reflects light in multiple directions. It is considered that irritating light can be irradiated over a wider range, and the worming efficiency can be improved. Therefore, by using the diffusive reflecting plate having the above diffusivity of about 30% or more, it is possible to provide an attracting insect trap with a further improved trapping ratio.

  Further, it is more desirable that the diffusivity of the reflecting plate 3 is configured so as to increase as it approaches the capturing unit 4. For example, as shown in FIGS. 1 (a) and 1 (b), the reflector 3 has a diffusivity of 94% in the proximity part a of the capture part 4, 70% in the intermediate part b, and 50% in the remote part. It is comprised so that. Since the reflector 3 is configured as described above, the highly attracting light diffuses and reflects more in the vicinity of the capture unit 4, so that the insects attracted by the light source 2 gather in the vicinity of the capture unit 4. This improves insect trapping efficiency.

  The capturing unit 4 includes a cover 5 disposed on the bottom surface of the apparatus body 1, an adhesive sheet 6 that captures attracted insects, and an adhesive sheet receiver 7. The cover 5 is a housing whose upper surface is open, and is formed so that its opening matches the bottom opening of the apparatus main body 1. As the material of the cover 5, methacrylic resin (PMMA), polycarbonate resin (PC), vinyl chloride or the like without an ultraviolet absorber is used. The pressure-sensitive adhesive sheet 6 is made of a transparent sheet base made of polyethylene terephthalate (PET), polypropylene, methacrylic resin (PMMA) or polyethylene and coated with butylene, urethane or natural rubber as a pressure-sensitive adhesive.

As shown in FIG. 1A, the adhesive sheet receiver 7 is disposed below the light source 2 so as to face the light emitted from the light source 2. The adhesive sheet receiver 7 includes an aluminum diffuse reflector, a Nisshin Steel stainless steel NSS431DP-2 diffuse reflector, a multilayer diffuse reflector, a white reflective plate coated with UV reflective fine particles (BaSO ₃ ), or a Rh (rhodium) plated diffuse reflector. A plate or the like is used. That is, the adhesive sheet receiver 7 has a reflection spectral characteristic that has a total reflectance of about 50% or more and a diffusivity of about 30% or more with respect to light having a wavelength of about 340 to 380 nm, as in the case of the reflector 3 described above. It is comprised from the material which has. Therefore, the attracting light of the light source 2 is diffusely reflected in the pressure sensitive adhesive sheet receiver 7 and the insect trapping efficiency by the pressure sensitive adhesive sheet 6 is improved. In addition, by providing the sheet base of the pressure-sensitive adhesive sheet 6 with the same reflection spectral characteristic as that of the reflective plate 3, the insect attracting property can be improved as in the case of the pressure-sensitive adhesive sheet receiver 7.
