Description

本発明は、紫外線を含む光を照射する光照射部を備えた害虫防除装置に関する。   The present invention relates to a pest control apparatus including a light irradiation unit that emits light including ultraviolet rays.

従来から、紫外線を含む光を照射する光源を備えた害虫捕獲用照明装置が知られている（例えば、特許文献１参照）。この装置は、紫外線を含む光を照射することで、光に対して走行性を持つ昆虫（害虫）を捕獲部まで誘引して捕獲する。この装置において、光源から照射される紫外線は、ＵＶ−Ａ（波長成分３２０〜３８０ｎｍ）であり、昆虫のすう光性に合わせた３５０〜３７５ｎｍの波長域にピーク波長を持つ。   2. Description of the Related Art Conventionally, a pest capturing illumination device including a light source that emits light including ultraviolet rays is known (see, for example, Patent Document 1). By irradiating light including ultraviolet rays, this device attracts and captures insects (pests) having a traveling property with respect to the light to the capture unit. In this apparatus, the ultraviolet light emitted from the light source is UV-A (wavelength component 320 to 380 nm), and has a peak wavelength in a wavelength range of 350 to 375 nm that matches the fluorescent property of insects.

この装置から照射される光は、夜間に害虫を誘引するのに有効であるが、太陽光に比べてＵＶ−Ａの紫外線波長成分が少ないので、日中に活動して夜間にほとんど行動しない農業における害虫（以下、昼行性農業害虫という）であるコナジラミ、アザミウマ、ハモグリバエ、カメムシ等の誘引には不向きである。すなわち、この装置は、日中に使用しても昼行性農業害虫に紫外線のコントラストを視認させることができないので、昼行性農業害虫を大量に捕獲することができない。   The light emitted from this device is effective for attracting pests at night, but has less UV-A wavelength components than sunlight, so it is active during the day and does not act much at night. It is unsuitable for attracting whiteflies, thrips, leafhoppers, stink bugs, etc., which are pests in Japan (hereinafter referred to as diurnal agricultural pests). That is, this apparatus cannot capture a large amount of diurnal agricultural pests because it cannot make the diurnal agricultural pests visually recognize the contrast of ultraviolet rays even when used during the daytime.

また、カラー反射板とフェロモン剤を備える害虫捕獲装置が知られている（例えば、特許文献２参照）。この装置は、カラー反射板によって反射された太陽光に含まれる可視光と、フェロモン剤に含まれる集合フェロモンとの組み合わせによって、日中に昼行性農業害虫を誘引して捕獲する。   In addition, a pest capturing apparatus including a color reflector and a pheromone agent is known (see, for example, Patent Document 2). This device attracts and captures diurnal agricultural pests during the day by a combination of visible light contained in sunlight reflected by the color reflector and aggregated pheromone contained in the pheromone agent.

しかしながら、この装置は、市販のカラー反射板の誘引性能が低いことから、日中に昼行性農業害虫を大量に誘引することができないために、害虫防除装置として使用できず、モニタリングのための装置としてしか使用できない。また、この装置は、フェロモン剤に含まれる集合フェロモンでは、特定の昼行性農業害虫しか誘引できないので、昼行性農業害虫を大量に誘引することができない。   However, this device cannot be used as a pest control device because it cannot attract a large amount of diurnal agricultural pests during the day because the attracting performance of commercially available color reflectors is low. Can only be used as a device. In addition, this apparatus cannot attract a large amount of diurnal agricultural pests because the aggregate pheromone contained in the pheromone agent can attract only specific diurnal agricultural pests.

特許第４１９７９６９号公報Japanese Patent No. 4197969 特許第３５４１２１７号公報Japanese Patent No. 3541217

本発明は、上記問題を解決するためになされたものであり、活動が活発な日中に昼行性農業害虫を大量に誘引して捕獲することができる害虫防除装置を提供することを目的とする。   The present invention has been made to solve the above-described problem, and an object of the present invention is to provide a pest control apparatus that can attract and capture a large amount of diurnal agricultural pests during active days. To do.

上記目的を達成するために請求項１の発明は、虫を誘引する光を照射する光照射部と、前記光照射部から照射される光により誘引された虫を捕獲するための捕獲部と、を備えた害虫防除装置において、前記光照射部は、２５０〜３３０ｎｍの波長域のうちの少なくとも一部の光を照射するようにしたものである。   In order to achieve the above object, the invention of claim 1 includes a light irradiation unit that irradiates light that attracts insects, a capture unit that captures insects attracted by light irradiated from the light irradiation unit, In the pest control apparatus provided with the above, the light irradiation unit irradiates at least a part of light in a wavelength range of 250 to 330 nm.

請求項２の発明は、請求項１に記載の害虫防除装置において、虫を誘引する匂いを発生させる匂い発生部をさらに備え、前記匂い発生部は、青葉アルコール及び青葉アルデヒドのうちの少なくとも一つを含む水溶液を匂い源とするものである。   The invention of claim 2 is the pest control apparatus according to claim 1, further comprising an odor generating part for generating an odor that attracts insects, wherein the odor generating part is at least one of green leaf alcohol and green leaf aldehyde. An odor source is an aqueous solution containing.

請求項１の発明によれば、光照射部から照射される光が、太陽光に含まれない光波長成分、及び太陽光に含まれているが照射の弱い光波長成分を有するので、太陽光の照射下でも昼行性農業害虫に紫外線のコントラストを視認させることが可能となるために、日中に昼行性農業害虫を大量に誘引して捕獲することができる。   According to the first aspect of the present invention, the light irradiated from the light irradiation unit has a light wavelength component that is not included in sunlight and a light wavelength component that is included in sunlight but weakly irradiated. Since the diurnal agricultural pests can be visually recognized even under irradiation, the diurnal agricultural pests can be attracted and captured in large quantities during the day.

請求項２の発明によれば、匂い発生部から発生する匂いが、昼行性農業害虫が視認できる範囲よりも遠方の場所から昼行性農業害虫を誘引するので、日中に昼行性農業害虫をより大量に誘引して捕獲することができる。   According to the invention of claim 2, the odor generated from the odor generating part attracts the diurnal agricultural pests from a location farther than the range where the diurnal agricultural pests can be visually recognized. Attract and capture more pests.

本発明の一実施形態に係る害虫防除装置について図面を参照して説明する。図１は、本実施形態の害虫防除装置１の構成を示す。この害虫防除装置１は、農業用のビニールハウス若しくはガラスハウス等の施設栽培、又は露地栽培などにおいて、野菜や花卉などの苗を育成する際に発生する虫（昼行性農業害虫）を防除するために用いられる。   A pest control apparatus according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a configuration of a pest control apparatus 1 of the present embodiment. This pest control apparatus 1 controls insects (daytime agricultural pests) that are generated when growing seedlings such as vegetables and flower buds in agricultural cultivation such as greenhouse greenhouses or glass houses, or outdoor cultivation. Used for.

害虫防除装置１は、苗床に栽培された植物Ｐに光を照射する光照射部２と、光照射部２から照射される光の波長制御を行うフィルタ３と、太陽光を反射する光反射誘引部４と、昼行性農業害虫を誘引する匂いを発生させる匂い発生部５と、誘引された昼行性農業害虫を捕獲する捕獲部６と、を備える。光照射部２と光反射誘引部４と匂い発生部５は、誘引された昼行性農業害虫を捕獲しやすいように捕獲部６の近傍に設けられる。害虫防除装置１は、光照射部２から照射される光によって遠方の場所にいる昼行性農業害虫をより誘引しやすくするために、植物Ｐの上方位置に支柱などによって設置される。   The pest control apparatus 1 includes a light irradiation unit 2 that irradiates light on the plant P cultivated on the seedbed, a filter 3 that controls the wavelength of light irradiated from the light irradiation unit 2, and a light reflection attraction that reflects sunlight. Unit 4, an odor generating unit 5 that generates an odor that attracts diurnal agricultural pests, and a capturing unit 6 that captures the attracted diurnal agricultural pests. The light irradiation part 2, the light reflection attracting part 4, and the odor generating part 5 are provided in the vicinity of the catching part 6 so as to easily catch the attracted diurnal agricultural pest. The pest control apparatus 1 is installed by a support or the like above the plant P in order to make it easier to attract diurnal agricultural pests in a distant place by the light emitted from the light irradiation unit 2.

光照射部２は、２５０〜３３０ｎｍの波長域の少なくとも一部の波長成分を含む光を照射する蛍光灯やＨＩＤランプ等であり、例えば、図２に示されるようなランプ特性を有する蛍光灯のＵＶ−Ｂランプにより構成される。図２の着色した領域である２５０〜３３０ｎｍの波長域には、太陽光に含まれていない光の波長域や、太陽光に含まれているが放射照度が少ない光の波長域が含まれると共に、昆虫すう光性のある光の波長域が含まれる。   The light irradiation unit 2 is a fluorescent lamp, an HID lamp, or the like that irradiates light including at least a part of a wavelength component in the wavelength range of 250 to 330 nm. For example, a fluorescent lamp having lamp characteristics as shown in FIG. It is composed of a UV-B lamp. The wavelength region of 250 to 330 nm, which is the colored region in FIG. 2, includes a wavelength region of light that is not included in sunlight and a wavelength region of light that is included in sunlight but has low irradiance. This includes the wavelength range of insect-sparkling light.

光照射部２は、蛍光灯であるとき、２５０〜３３０ｎｍの波長域の光を積極的に照射することのできるＵＶ−Ｂランプ（パナソニック電工株式会社製、品番ＹＧＲＫＸ２１７９９や、三共電気株式会社製、品番ＧＬ２０Ｅ）等が用いられる。また、光照射部２は、ＨＩＤランプであるとき、２５０〜３３０ｎｍの波長域の紫外線放射成分が多い水銀灯やメタルハライドランプ（パナソニック株式会社製、スカイビーム）、紫外線域に連続した発光スペクトルを有するキセノンランプ、又は２５０〜３３０ｎｍに発光特性を有するＬＥＤ等が用いられる。   When the light irradiation unit 2 is a fluorescent lamp, a UV-B lamp (manufactured by Panasonic Electric Works Co., Ltd., product number YGRKX21799, manufactured by Sankyo Electric Co., Ltd., which can actively irradiate light in the wavelength range of 250 to 330 nm, No. GL20E) is used. In addition, when the light irradiation unit 2 is an HID lamp, a mercury lamp or a metal halide lamp (manufactured by Panasonic Corporation, Sky Beam) with a large amount of ultraviolet radiation components in the wavelength range of 250 to 330 nm, xenon having an emission spectrum continuous in the ultraviolet range. A lamp or an LED having light emission characteristics at 250 to 330 nm is used.

さらに、光照射部２から照射される光は、光照射部２の発光表面における２５０〜３３０ｎｍの波長域の光の合計量が１００μＷ／ｃｍ２以上となるように制御される。この制御によって、害虫防除装置１は、太陽光の照射下でも昼行性農業害虫に紫外線のコントラストを視認させることができるので、昼行性農業害虫を効率よく誘引することができる。 Furthermore, the light irradiated from the light irradiation unit 2 is controlled so that the total amount of light in the wavelength region of 250 to 330 nm on the light emitting surface of the light irradiation unit 2 is 100 μW / cm 2 or more. By this control, the pest control apparatus 1 can cause the diurnal agricultural pest to visually recognize the contrast of ultraviolet rays even under the irradiation of sunlight, and therefore can attract the diurnal agricultural pest efficiently.

光照射部２の発光表面における２５０〜３３０ｎｍの波長域の光の合計量を１００μＷ／ｃｍ２以上に制御する手段は、例えば、調光制御ができるライトコントローラ（図示せず）により構成される。光照射部２は、このライトコントローラにより電気的に制御される。制御手段の構成は、これに限定されず、例えば、フィルタ３、光照射部２のランプに形成した塗膜や蒸着膜、又はこれらの組み合わせによって制御してもよい。 The means for controlling the total amount of light in the wavelength region of 250 to 330 nm on the light emitting surface of the light irradiation unit 2 to 100 μW / cm 2 or more is constituted by, for example, a light controller (not shown) capable of dimming control. The light irradiation unit 2 is electrically controlled by this light controller. The configuration of the control means is not limited to this, and may be controlled by, for example, a filter 3, a coating film formed on the lamp of the light irradiation unit 2, a vapor deposition film, or a combination thereof.

フィルタ３は、ガラスや樹脂などを材料とし、光照射部２、及び光照射部２から照射される光の照射対象である植物Ｐの間に設けられる。フィルタ３は、光照射部２から照射される光のうちのＵＶ−Ａ、すなわち３４０〜３８０ｎｍの光波長成分を殆ど透過しないように構成される。このため、光照射部２から植物Ｐに照射される光は、３４０〜３８０ｎｍの光波長成分がフィルタ３によってカットされて略ゼロとなる。害虫防除装置１は、光照射部２から照射する光のうちの３４０〜３８０ｎｍの光波長成分を略ゼロとすることによって、灰色カビ病などの糸状菌（カビ）の菌糸伸長を助長しないので、植物病害を防除することができる。光束量が比較的多く、かつ、２５０〜３３０ｎｍの紫外線領域の光を比較的多く含むメタルハライドランプ、キセノンランプ等を光照射部２として用いる場合、フィルタ３は効果的である。   The filter 3 is made of glass, resin, or the like, and is provided between the light irradiation unit 2 and the plant P that is an irradiation target of light irradiated from the light irradiation unit 2. The filter 3 is configured so as to hardly transmit UV-A of light irradiated from the light irradiation unit 2, that is, a light wavelength component of 340 to 380 nm. For this reason, the light with which the plant P is irradiated from the light irradiation unit 2 is substantially zero because the light wavelength component of 340 to 380 nm is cut by the filter 3. The pest control apparatus 1 does not promote hyphal elongation of filamentous fungi such as gray mold disease by making the light wavelength component of 340 to 380 nm of light irradiated from the light irradiation unit 2 substantially zero, Plant diseases can be controlled. The filter 3 is effective when a metal halide lamp, a xenon lamp, or the like having a relatively large amount of light flux and a relatively large amount of light in the ultraviolet region of 250 to 330 nm is used as the light irradiation unit 2.

また、３４０〜３８０ｎｍの光波長成分が略ゼロとなるように制御する他の手段としては、フィルタ３を用いることに加えて、上述した光照射部２の発光表面における２５０〜３３０ｎｍの波長域の光の合計量を制御する手段により、３４０〜３８０ｎｍの光波長成分をカットしてもよい。   Further, as another means for controlling the light wavelength component of 340 to 380 nm to be substantially zero, in addition to using the filter 3, the wavelength region of 250 to 330 nm on the light emitting surface of the light irradiation unit 2 described above is used. The light wavelength component of 340 to 380 nm may be cut by means for controlling the total amount of light.

光照射部２は、図３に示されるように、放電によって電子を照射し、その電子のエネルギーを水銀原子が受け取ることによって紫外線を照射し、その紫外線が蛍光体２１に吸収されて光を照射する蛍光灯であってもよい。この蛍光灯により光照射部２が構成される場合、２５０〜３３０ｎｍの波長域で多く発光し、３４０〜３８０ｎｍの波長域で発光しない蛍光体２１を用いることにより、３４０〜３８０ｎｍの光波長成分をカットするようにしてもよい。   As shown in FIG. 3, the light irradiation unit 2 irradiates electrons by discharge, irradiates ultraviolet rays when mercury atoms receive energy of the electrons, and the ultraviolet rays are absorbed by the phosphor 21 and irradiates light. It may be a fluorescent lamp. When the light irradiation unit 2 is configured by this fluorescent lamp, by using the phosphor 21 that emits much light in the wavelength region of 250 to 330 nm and does not emit light in the wavelength region of 340 to 380 nm, the light wavelength component of 340 to 380 nm is obtained. You may make it cut.

光反射誘引部４は、２２０〜３９０ｎｍの光波長成分の反射率を５％以下とする反射板（以下、低ＵＶ反射板という）であり、光照射部２の光が照射される範囲に、地面に対して垂直となるようにして配置される。光反射誘引部４は、光照射部２の光が照射される範囲に光反射誘引部４が配置されることによって、昼行性農業害虫から見たときの圃場内の空間に対する紫外線のコントラストが増加されるので、誘引効果が向上する。なお、光反射誘引部４は、地面に対して水平に設置されてもよい。   The light reflection attraction unit 4 is a reflection plate (hereinafter referred to as a low UV reflection plate) having a reflectance of a light wavelength component of 220 to 390 nm of 5% or less, and in a range irradiated with light from the light irradiation unit 2, Arranged so as to be perpendicular to the ground. The light reflection attraction unit 4 has the light reflection attraction unit 4 arranged in a range where the light irradiation unit 2 is irradiated, so that the ultraviolet contrast with respect to the space in the field when viewed from diurnal agricultural pests is increased. Since it is increased, the attraction effect is improved. In addition, the light reflection attraction part 4 may be installed horizontally with respect to the ground.

光反射誘引部４は、具体的には、カラー反射板（主に黄色であればアゾ系、キノフタロン系など、青色フタロシアニン系、コバルト系など）の表面に、２２０〜３９０ｎｍの光波長成分の反射率を５％以下とするための低反射処理を施すことによって構成される。光反射誘引部４は、昼行性農業害虫によって可視光域の好む色が異なっており、その表面が黄色のとき、コナジラミ、ハモグリバエ等を誘引し、その表面が青色のとき、アザミウマ等を誘引する。   Specifically, the light reflection attraction part 4 reflects a light wavelength component of 220 to 390 nm on the surface of a color reflector (mainly azo, quinophthalone, blue phthalocyanine, cobalt, etc. if yellow). It is configured by performing a low reflection process for setting the rate to 5% or less. The light reflection attracting part 4 has different colors preferred by the daytime agricultural pests. When the surface is yellow, it attracts whiteflies, leafhoppers, etc. When the surface is blue, it attracts thrips, etc. To do.

光反射誘引部４の中でも表面が黄色の低ＵＶ反射板は、図４（ａ）に示されるように、グラフ上の着色した領域である２２０〜３９０ｎｍの波長域における反射率が、表面が黄色の市販の反射板（以下、市販黄色反射板という）に比べて低い。同様に、表面が青色の低ＵＶ反射板は、図４（ｂ）に示されるように、グラフ上の着色した領域である２２０〜３９０ｎｍの波長域における反射率が、表面が青色の市販の反射板（以下、市販青色反射板という）に比べて低い。   As shown in FIG. 4 (a), the low UV reflector having a yellow surface among the light reflection attracting portions 4 has a yellow surface with a reflectance in a wavelength region of 220 to 390 nm which is a colored region on the graph. Compared to a commercially available reflector (hereinafter referred to as a commercially available yellow reflector). Similarly, as shown in FIG. 4B, the low-UV reflector having a blue surface has a reflectance in a wavelength region of 220 to 390 nm, which is a colored region on the graph, and has a blue surface. Low compared to a plate (hereinafter referred to as a commercially available blue reflector).

光反射誘引部４を構成するカラー反射板の材質は、特に限定されないが、カラープラスチックや、カラー塗装が施されたプラスチック板やシート等から成るのが望ましい。低反射処理は、カラー反射板の表面に低屈折率材料（フッ素系など）の膜や多層膜を反射防止のために設けたり、又はカラー反射板の表面に４００ｎｍ〜１ｍｍ程度の凹凸を多重反射させるために設けたりすることによって行う。カラー反射板の表面に４００ｎｍ〜１ｍｍ程度の凹凸を設けることは、安価で効果的な低反射処理であり、樹脂や塗膜表面への凹凸の成型や転写、エッチング等によって行われる。   The material of the color reflection plate constituting the light reflection attraction part 4 is not particularly limited, but it is preferably made of a color plastic, a plastic plate or sheet coated with color, or the like. Low reflection processing is performed by providing a film of a low refractive index (such as fluorine) or a multilayer film on the surface of the color reflector to prevent reflection, or by multiplying irregularities of about 400 nm to 1 mm on the surface of the color reflector. It is done by providing it to make it. Providing irregularities of about 400 nm to 1 mm on the surface of the color reflector is an inexpensive and effective low reflection treatment, and is performed by molding, transferring, etching, etc., irregularities on the surface of the resin or coating film.

光反射誘引部４は、上記特性を有した上でさらに３８０〜６００ｎｍの光波長成分の透過率ピーク波長付近における透過率を１０％以上とする反射板であってもよい。この光反射誘引部４は、カラー反射板の着色剤の添加濃度を調節して作成され、具体的には、カラープラスチックの板厚を調整することによって、又はプラスチック板やシート等の透明材料に施されたカラー塗装の塗膜厚を調整することによって作成される。   The light reflection attracting part 4 may be a reflector having the above characteristics and a transmittance of 10% or more near the transmittance peak wavelength of the light wavelength component of 380 to 600 nm. This light reflection attracting part 4 is created by adjusting the concentration of the colorant added to the color reflector, specifically, by adjusting the thickness of the color plastic, or on a transparent material such as a plastic plate or sheet. It is created by adjusting the coating thickness of the applied color coating.

匂い発生部５は、青葉アルコール又は青葉アルデヒドのうちの少なくとも一部を含む水溶液を匂い源とし、この匂い源をレギュレータ（図示せず）等によって揮発・蒸散濃度を制御して、虫を誘引する匂いを発生させる。匂い源の蒸散は、自然蒸散でもよいが、超音波蒸散や加熱蒸散などであると制御しやすい。匂い源に含まれる青葉アルコール又は青葉アルデヒドの濃度は、圃場の大きさによって可変できるが、特に、０．１〜１０％程度の水溶液希釈が望ましい。また、害虫防除装置１は、匂い源を含浸させた光反射誘引部４を用いてもよく、誘引効果がより向上する。なお、匂い発生部５は、害虫防除装置１の製造コストの上昇を抑えるために設置されなくてもよい。   The odor generating unit 5 uses an aqueous solution containing at least a part of green leaf alcohol or green leaf aldehyde as an odor source, and controls the volatilization / transpiration concentration with a regulator (not shown) or the like to attract insects. Generates an odor. The odor transpiration may be natural transpiration, but it is easy to control if it is ultrasonic transpiration or heat transpiration. The concentration of green leaf alcohol or green leaf aldehyde contained in the odor source can vary depending on the size of the field, but it is particularly preferable to dilute the aqueous solution to about 0.1 to 10%. Moreover, the pest control apparatus 1 may use the light reflection attracting part 4 impregnated with the odor source, and the attracting effect is further improved. Note that the odor generating unit 5 may not be installed in order to suppress an increase in manufacturing cost of the pest control apparatus 1.

捕獲部６は、水盤式、粘着材、ファン式（吸引式）などで構成され、光照射部２、光反射誘引部４及び匂い発生部５によって誘引された昼行性農業害虫を捕獲する。なお、捕獲部６は、表面に粘着剤が塗布された光反射誘引部４のように光反射誘引部４と一体的に構成されていてもよいし、電撃式で構成される殺虫部であってもよい。匂い発生部５は、捕獲部６の周辺に、又は捕獲部６が上記のように光反射誘引部４と一体的に構成されているときは光反射誘引部４の周辺に設置される。   The capture unit 6 is configured by a laver type, an adhesive material, a fan type (suction type), and the like, and captures diurnal agricultural pests attracted by the light irradiation unit 2, the light reflection attracting unit 4, and the odor generating unit 5. The capturing unit 6 may be configured integrally with the light reflection attraction unit 4 such as the light reflection attraction unit 4 having a surface coated with an adhesive, or may be an insecticidal unit configured with an electric shock type. May be. The odor generating unit 5 is installed around the light reflection attracting unit 4 around the capturing unit 6 or when the capturing unit 6 is integrally formed with the light reflection attracting unit 4 as described above.

植物Ｐが比較的密に植えられて栽培される場合、光照射部２が植物Ｐの上方に設置されるだけでは、植物Ｐの影により、近接する植物Ｐの側部及び下部に十分に光が照射されず、植物Ｐの側部及び下部が他の部分よりも害虫を防除しにくくなる虞がある。そのような場合には、図５に示されるように、植物Ｐの上方に配設される害虫防除装置１に加えて、植物Ｐの側方及び下方にそれぞれ同様の害虫防除装置１が配設されることが望ましい。以下、植物Ｐの上方、側方及び下方にある光照射部２をそれぞれ上部光照射部２ａ、側部光照射部２ｂ、下部光照射部２ｃという。なお、これら害虫防除装置１の個数は、１個ずつに限定されず、複数個ずつであってもよい。   When the plant P is planted and cultivated relatively densely, the light irradiation unit 2 is simply placed above the plant P, and the shadow of the plant P causes sufficient light on the side and lower portions of the adjacent plant P. Is not irradiated, and there is a possibility that the side part and the lower part of the plant P are more difficult to control pests than the other parts. In such a case, as shown in FIG. 5, in addition to the pest control apparatus 1 disposed above the plant P, the same pest control apparatus 1 is disposed on the side and below the plant P, respectively. It is desirable that Hereinafter, the light irradiation unit 2 above, on the side and below the plant P is referred to as an upper light irradiation unit 2a, a side light irradiation unit 2b, and a lower light irradiation unit 2c, respectively. In addition, the number of these pest control apparatuses 1 is not limited to one each, and may be plural.

次に、害虫防除装置１の光照射部２ａ、２ｂ、２ｃの平面配置について、図６を参照して説明する。植物Ｐが畝Ｆに合わせて複数植えられている場合には、上部光照射部２ａ、側部光照射部２ｂ及び下部光照射部２ｃが複数個ずつ設けられることが望ましい。上部光照射部２ａは畝Ｆに沿って所定の間隔で設置され、側部光照射部２ｂ及び下部光照射部２ｃは畝Ｆと平行に、すなわち植物Ｐの列と平行に連続して設置される。側部光照射部２ｂ及び下部光照射部２ｃは、例えば、シリンダ等で覆われて防水加工が施された蛍光灯により構成され、畝Ｆと平行に並設される。側部光照射部２ｂ及び下部光照射部２ｃは、ホローライトガイド方式の照明器具、光ファイバ又は細長い形状のＥＬ器具等の光照射部２により構成されていてもよい。このように、上部光照射部２ａ、側部光照射部２ｂ及び下部光照射部２ｃは並べて設置されるので、植物Ｐが広い範囲にわたって列状に植えられている場合においても、植物Ｐの側部及び下部に効率よく光を照射することができる。   Next, the planar arrangement of the light irradiation units 2a, 2b, and 2c of the pest control apparatus 1 will be described with reference to FIG. When a plurality of plants P are planted in accordance with the ridge F, it is desirable to provide a plurality of upper light irradiation units 2a, side light irradiation units 2b, and lower light irradiation units 2c. The upper light irradiation unit 2a is installed along the ridge F at a predetermined interval, and the side light irradiation unit 2b and the lower light irradiation unit 2c are installed continuously in parallel with the ridge F, that is, in parallel with the rows of plants P. The The side light irradiating unit 2b and the lower light irradiating unit 2c are made of, for example, a fluorescent lamp that is covered with a cylinder or the like and is waterproofed, and is arranged in parallel with the ridge F. The side light irradiation unit 2b and the lower light irradiation unit 2c may be configured by a light irradiation unit 2 such as a hollow light guide type lighting device, an optical fiber, or an elongated EL device. Thus, since the upper light irradiation part 2a, the side light irradiation part 2b, and the lower light irradiation part 2c are installed side by side, even when the plants P are planted in rows over a wide range, It is possible to efficiently irradiate light on the part and the lower part.

害虫防除装置１は、照度センサやタイマー等によって光照射が制御され、主に日中に光照射を行う。また、害虫防除装置１は、白色光などの人工光を照射するキセノンランプを組み合わせて用いて、人工光の照射と、光照射部２ａ、２ｂ、２ｃからの光の照射とを同時に行うことで、日中だけでなく夜間に光照射を行ってもよい。   The pest control apparatus 1 is controlled to emit light by an illuminance sensor, a timer, or the like, and performs light irradiation mainly during the daytime. Further, the pest control apparatus 1 uses a combination of a xenon lamp that emits artificial light such as white light, and simultaneously performs irradiation of artificial light and light from the light irradiation units 2a, 2b, and 2c. The light irradiation may be performed not only during the day but also at night.

また、光照射部２ａ、２ｂ、２ｃの配光及び光量は、植物Ｐの生育に合わせて調整してもよい。例えば、初期の生育ステージにおいて植物Ｐがあまり生育しておらず、植物Ｐがまだ小さい場合には、植物Ｐに照射される光量を少なくする。植物Ｐに照射される光量を少なくするには、上部光照射部２ａを消灯させると共に、側部光照射部２ｂ及び下部光照射部２ｃを点灯させ、さらに側部光照射部２ｂ及び下部光照射部２ｃの取付角度などを調整して、配光の広がりを抑えることによって行う。植物Ｐが大きくなるにつれて上部光照射部２ａを点灯させると共に、側部光照射部２ｂ及び下部光照射部２ｃの取付角度などを調整することにより、配光を広くし、植物Ｐに照射される光量を多くする。なお、側部光照射部２ｂ及び下部光照射部２ｃの配光及び光量の調整の仕方は、上述した例に限定されず、上部光照射部２ａの光量が少ない場合や、植物Ｐが比較的多くの光を必要とする場合には、初期の生育ステージにおいても上部光照射部２ａを点灯させても構わない。   Moreover, you may adjust the light distribution and light quantity of the light irradiation parts 2a, 2b, and 2c according to the growth of the plant P. FIG. For example, if the plant P has not grown much at the initial growth stage and the plant P is still small, the amount of light irradiated to the plant P is reduced. In order to reduce the amount of light irradiated to the plant P, the upper light irradiation unit 2a is turned off, the side light irradiation unit 2b and the lower light irradiation unit 2c are turned on, and the side light irradiation unit 2b and the lower light irradiation are further turned on. This is done by adjusting the mounting angle of the portion 2c and the like to suppress the spread of the light distribution. As the plant P becomes larger, the upper light irradiation unit 2a is turned on, and the light distribution is broadened by adjusting the attachment angles of the side light irradiation unit 2b and the lower light irradiation unit 2c, and the plant P is irradiated. Increase the amount of light. In addition, how to adjust the light distribution and the light amount of the side light irradiation unit 2b and the lower light irradiation unit 2c is not limited to the above-described example. When a lot of light is required, the upper light irradiation unit 2a may be turned on even in the initial growth stage.

また、害虫防除装置１は、害虫誘引効果をより確実なものとするために、例えば、太陽光から紫外線、特に、ＵＶ−Ａをカットすることができる機能を有する農業用のビニールハウスやガラスハウス（以下、ハウスという）内に設置されることが望ましい。このようなハウスの中で害虫防除装置１が用いられる場合、太陽光のＵＶ−Ａをカットすることができるので、害虫防除装置１の害虫誘引はより効果的となる。   Moreover, in order to make the pest control effect more reliable, the pest control apparatus 1 is, for example, an agricultural vinyl house or glass house having a function of cutting ultraviolet rays from sunlight, particularly UV-A. It is desirable to install in the house (hereinafter referred to as house). When the pest control apparatus 1 is used in such a house, since the UV-A of sunlight can be cut, the pest attraction of the pest control apparatus 1 becomes more effective.

下記表１は、従来の補虫用ランプの光照射による害虫誘引捕獲数と、本実施形態に係る害虫防除装置１の光照射部２の光照射による害虫誘引捕獲数を示す。この実験において、植物体はバラであり、昼行性農業害虫はアザミウマである。従来の補虫用ランプは、３４０〜３８０ｎｍの光波長成分を有する捕虫器用蛍光灯であるＵＶ-Ａランプ（パナソニック株式会社製、品番：ＦＬ２０ＳＢＬＫ）を用いた。本実施形態の光照射部２は、２８０〜３４０ｎｍの光波長成分を有するＵＶ-Ｂランプ（パナソニック電工株式会社製、品番：ＹＧＲＫＸ２１７９９）と、１００〜２８０ｎｍの光波長成分を有するＵＶ-Ｃランプ（日進電子工業株式会社製、品番：ＳＸ−２０−１２８）を組み合わせて用いた。捕獲部６は、ＵＶ−Ａランプ、ＵＶ−ＢランプとＵＶ−Ｃランプの組み合わせのいずれの場合も、透明粘着シートを用いた。実験は、ハウス中で７日間行われ、日の出から日の入までの日中にランプを点灯させた。
Table 1 below shows the number of insect pests attracted by light irradiation of a conventional insect lamp and the number of insect pests attracted by light irradiation of the light irradiation unit 2 of the pest control apparatus 1 according to this embodiment. In this experiment, the plant body is a rose and the diurnal agricultural pest is a thrips. As a conventional insect lamp, a UV-A lamp (manufactured by Panasonic Corporation, product number: FL20SBLK), which is a fluorescent lamp for an insect trap having a light wavelength component of 340 to 380 nm, was used. The light irradiation unit 2 of this embodiment includes a UV-B lamp (manufactured by Panasonic Electric Works Co., Ltd., product number: YGRKX21799) having a light wavelength component of 280 to 340 nm, and a UV-C lamp having a light wavelength component of 100 to 280 nm ( Nissin Electronics Co., Ltd., product number: SX-20-128) was used in combination. The capture unit 6 used a transparent adhesive sheet in any case of a combination of a UV-A lamp, a UV-B lamp, and a UV-C lamp. The experiment was conducted in the house for 7 days, and the lamp was turned on during the day from sunrise to sunset.

上記実験の結果、ＵＶ-ＢランプとＵＶ−Ｃランプの組み合わせは、ＵＶ-Ａランプに比べて約１１倍の誘引効果があった。そのため、本実施形態の害虫防除装置１は、光照射部２の照射する光が、太陽光に含まれない光波長成分、及び太陽光に含まれているが照射の弱い光波長成分を有するので、太陽光の照射下でも昼行性農業害虫に紫外線のコントラストを視認させることが可能となるために、日中に昼行性農業害虫を大量に誘引して捕獲することができる。   As a result of the above experiment, the combination of the UV-B lamp and the UV-C lamp had an attracting effect about 11 times that of the UV-A lamp. Therefore, the pest control apparatus 1 of the present embodiment has light wavelength components that are not included in sunlight and light wavelength components that are included in sunlight but weakly irradiated. Since the diurnal agricultural pests can be visually recognized by the diurnal agricultural pests even under sunlight, the diurnal agricultural pests can be attracted and captured in a large amount during the day.

下記表２は、従来の反射板による害虫誘引捕獲数と、本実施形態に係る害虫防除装置１の光反射誘引部４による害虫誘引捕獲数を示す。この実験において、植物体はトマトであり、昼行性農業害虫はコナジラミである。従来の反射板は、２２０〜３９０ｎｍの光波長成分の反射率が７％以上である市販黄色反射板（アリスタライフサイエンス株式会社製、商品名：ホリバー）を用いた。本実施形態の光反射誘引部４は、２２０〜３９０ｎｍの光波長成分の反射率が５．０％と３．８％の２種類の黄色の低ＵＶ反射板を用いる。捕獲部６は、市販黄色反射板、黄色の低ＵＶ反射板のいずれの場合も、反射板の表面に塗布した粘着剤とした。実験は、ハウス中で７日間行われた。
Table 2 below shows the number of insect pests attracted by the conventional reflector and the number of insects attracted by the light reflection attracting unit 4 of the pest control apparatus 1 according to this embodiment. In this experiment, the plant body is a tomato and the diurnal agricultural pest is a whitefly. As the conventional reflector, a commercially available yellow reflector (trade name: HORIVER, manufactured by Arista Life Science Co., Ltd.) having a reflectance of a light wavelength component of 220 to 390 nm of 7% or more was used. The light reflection attraction part 4 of this embodiment uses two types of yellow low UV reflectors having a reflectance of 5.0% and 3.8% for light wavelength components of 220 to 390 nm. The capture unit 6 was a pressure-sensitive adhesive applied to the surface of the reflector in both cases of a commercially available yellow reflector and a yellow low UV reflector. The experiment was conducted in the house for 7 days.

上記実験の結果、２２０〜３９０ｎｍの光波長成分の反射率が５．０％の黄色の低ＵＶ反射板は、市販黄色反射板に比べて約２倍の誘引効果があった。また、２２０〜３９０ｎｍの光波長成分の反射率が３．８％の黄色の低ＵＶ反射板は、市販黄色反射板に比べて約４倍の誘引効果があった。そのため、本実施形態の害虫防除装置１は、光反射誘引部４が紫外線をほとんど反射しないので、太陽光と比較して空間における紫外線のコントラストが高くなり、昼行性農業害虫が光反射誘引部４に強く誘引されるために、日中に昼行性農業害虫を大量に誘引して捕獲することができる。   As a result of the above experiment, the yellow low UV reflecting plate having a reflectance of 5.0% of the light wavelength component of 220 to 390 nm had an attracting effect about twice that of the commercially available yellow reflecting plate. Moreover, the yellow low UV reflecting plate having a reflectance of 3.8% of the light wavelength component of 220 to 390 nm had an attracting effect about 4 times that of the commercially available yellow reflecting plate. Therefore, in the pest control apparatus 1 of the present embodiment, the light reflection attracting unit 4 hardly reflects the ultraviolet rays, so that the contrast of the ultraviolet rays in the space is higher than sunlight, and the diurnal agricultural pests are reflected in the light reflection attracting unit. Because it is strongly attracted by 4, it can attract and capture a large amount of diurnal agricultural pests during the day.

下記表３は、従来の反射板による害虫誘引捕獲数と、従来の反射板に本実施形態に係る害虫防除装置１の匂い発生部５を組み合わせたものによる害虫誘引捕獲数を示す。この実験において、植物体はトマトであり、昼行性農業害虫はコナジラミである。従来の反射板は、２２０〜３９０ｎｍの光波長成分の反射率が７％以上である市販黄色反射板を用いた。本実施形態の匂い発生部５は、匂い誘引源が青葉アルコールの１％希釈水溶液であり、加熱蒸散方式のものを用いる。捕獲部６は、市販黄色反射板の表面に塗布した粘着剤とした。実験は、ハウス中で７日間行われた。
Table 3 below shows the number of insect pests attracted by the conventional reflector and the number of insects attracted by the conventional reflector combined with the odor generating part 5 of the insect pest control apparatus 1 according to this embodiment. In this experiment, the plant body is a tomato and the diurnal agricultural pest is a whitefly. As the conventional reflector, a commercially available yellow reflector having a reflectance of light wavelength components of 220 to 390 nm of 7% or more was used. The odor generating unit 5 of the present embodiment uses a 1% diluted aqueous solution of green leaf alcohol as the odor attracting source, and uses a heat transpiration type. The capture unit 6 was an adhesive applied to the surface of a commercially available yellow reflector. The experiment was conducted in the house for 7 days.

上記実験の結果、市販黄色反射板と匂い誘引源が青葉アルコールの１％希釈水溶液である匂い発生部５を組み合わせたものは、市販黄色反射板のみに比べて、約３倍の誘引効果があった。そのため、本実施形態の害虫防除装置１は、匂い発生部５から発生する匂いが、昼行性農業害虫の視認できる範囲よりも遠方の場所から昼行性農業害虫を誘引するので、日中に昼行性農業害虫をより大量に誘引して捕獲することができる。   As a result of the above experiment, the combination of the commercially available yellow reflector and the odor generating part 5 whose odor attracting source is a 1% diluted aqueous solution of green leaf alcohol has an attracting effect about 3 times that of the commercially available yellow reflector alone. It was. Therefore, since the odor generated from the odor generating unit 5 attracts the diurnal agricultural pests from a location farther than the range where the diurnal agricultural pests can be visually recognized, the pest control apparatus 1 of the present embodiment can be used during the day. Can attract and capture more diurnal agricultural pests.

下記表４は、従来の反射板による害虫誘引捕獲数と、本実施形態に係る害虫防除装置１の光照射部２と光反射誘引部４と匂い発生部５を組み合わせたものによる害虫誘引捕獲数を示す。この実験において、植物体はナスであり、昼行性農業害虫はアザミウマである。従来の反射板は、２２０〜３９０ｎｍの光波長成分の反射率が７％以上である市販青色反射板（アリスタライフサイエンス株式会社製、商品名：ホリバー）を用いた。本実施形態の光照射部２は、２８０〜３４０ｎｍの光波長成分を有するＵＶ-Ｂランプ、及び１００〜２８０ｎｍの光波長成分を有するＵＶ-Ｃランプを用いた。光反射誘引部４は、反射率が２２０〜３９０ｎｍの光波長成分の反射率が３．８％の青色の低ＵＶ反射板を用いた。匂い発生部５は、匂い誘引源が青葉アルコールの３％希釈水溶液であり、加熱蒸散方式のものを用いた。捕獲部６は、市販青色反射板、青色の低ＵＶ反射板のいずれの場合も、反射板の表面に塗布した粘着剤とした。実験は、ハウス中で７日間行われ、日の出から日の入までの日中にランプを点灯させた。
Table 4 below shows the number of pests attracted by the conventional reflector, and the number of pests attracted by the combination of the light irradiation unit 2, the light reflection attraction unit 4 and the odor generating unit 5 of the pest control apparatus 1 according to this embodiment. Indicates. In this experiment, the plant body is eggplant and the diurnal agricultural pest is thrips. As the conventional reflector, a commercially available blue reflector (trade name: HORIVER, manufactured by Arista Life Sciences Inc.) having a reflectance of a light wavelength component of 220 to 390 nm of 7% or more was used. The light irradiation unit 2 of the present embodiment uses a UV-B lamp having a light wavelength component of 280 to 340 nm and a UV-C lamp having a light wavelength component of 100 to 280 nm. As the light reflection attraction part 4, a blue low UV reflection plate having a reflectance of 3.8% for a light wavelength component having a reflectance of 220 to 390 nm was used. The odor generating part 5 is a 3% diluted aqueous solution of green leaf alcohol as the odor attracting source, and a heat transpiration system is used. The capturing unit 6 was an adhesive applied to the surface of the reflective plate in both cases of a commercially available blue reflective plate and a blue low UV reflective plate. The experiment was conducted in the house for 7 days, and the lamp was turned on during the day from sunrise to sunset.

上記実験の結果、ＵＶ-ＢランプとＵＶ−Ｃランプ、青色の低ＵＶ反射板、匂い誘引源が青葉アルコールの１％希釈水溶液である匂い発生部５を組み合わせたものは、市販青色反射板に比べて、約２０倍の誘引効果があった。本実施形態の害虫防除装置１は、紫外線（ＵＶ−Ｂ、ＵＶ−Ｃ）を照射する光照射部２と、紫外線（ＵＶ−Ａ、ＵＶ−Ｂ、ＵＶ−Ｃ）をほとんど反射させない光反射誘引部４とを組み合わせて用いることで、空間における紫外線のコントラストをより高くすることができる。そのため、害虫防除装置１は、昼行性農業害虫を光反射誘引部４により強く誘引するので、日中に昼行性農業害虫を大量に誘引して捕獲することができる。また、本実施形態の害虫防除装置１は、光照射部２と光反射誘引部４によって昼行性農業害虫の視認できる範囲にいる昼行性農業害虫し、さらに、匂い発生部５によって昼行性農業害虫の視認できる範囲よりも遠方の場所にいる昼行性農業害虫も誘引するので、日中に昼行性農業害虫をより大量に誘引して捕獲することができる。   As a result of the above experiment, a combination of a UV-B lamp and a UV-C lamp, a blue low UV reflector, and an odor generating part 5 whose odor attracting source is a 1% diluted aqueous solution of green leaf alcohol is combined with a commercially available blue reflector. In comparison, there was an attractive effect of about 20 times. The pest control apparatus 1 of this embodiment includes a light irradiation unit 2 that irradiates ultraviolet rays (UV-B, UV-C), and a light reflection attraction that hardly reflects ultraviolet rays (UV-A, UV-B, UV-C). By using the unit 4 in combination, the ultraviolet contrast in the space can be further increased. Therefore, since the pest control apparatus 1 attracts diurnal agricultural pests strongly by the light reflection attracting unit 4, it can attract and capture a large amount of diurnal agricultural pests during the day. In addition, the pest control apparatus 1 of the present embodiment performs diurnal agricultural pests in a range where the diurnal agricultural pests can be visually recognized by the light irradiation unit 2 and the light reflection attracting unit 4, and further, the odor generating unit 5 performs the diurnal operation. Since diurnal agricultural pests that are located farther than the visible range of pests of agricultural pests are also attracted, it is possible to attract and capture a large amount of diurnal agricultural pests during the day.

下記表５は、従来の反射板による害虫誘引捕獲数と、本実施形態に係る害虫防除装置１の光反射誘引部４による害虫誘引捕獲数とを示す。この実験において、植物体はトマトであり、昼行性農業害虫はコナジラミである。従来の反射板は、２２０〜３９０ｎｍの光波長成分の反射率が７％以上である市販黄色反射板を用いた。本実施形態の光反射誘引部４は、反射率が２２０〜３９０ｎｍの光波長成分の反射率が３．８％の黄色の低ＵＶ反射板と、反射率が２２０〜３９０ｎｍの光波長成分の反射率が３．７％であり、かつ、３８０〜６００ｎｍの光波長成分の透過率付近における透過率が１３％である黄色の低ＵＶ反射板の２種類を用いる。捕獲部６は、市販黄色反射板、黄色の低ＵＶ反射板のいずれの場合も、反射板の表面に塗布した粘着剤とした。実験は、ハウス中で７日間行われ、日の出から日の入までの日中にランプを点灯させた。
Table 5 below shows the number of insect pests attracted by the conventional reflector and the number of insects attracted by the light reflection attracting unit 4 of the pest control apparatus 1 according to this embodiment. In this experiment, the plant body is a tomato and the diurnal agricultural pest is a whitefly. As the conventional reflector, a commercially available yellow reflector having a reflectance of light wavelength components of 220 to 390 nm of 7% or more was used. The light reflection attraction part 4 of this embodiment includes a yellow low UV reflector having a reflectance of 3.8% for a light wavelength component having a reflectance of 220 to 390 nm, and a reflection for a light wavelength component having a reflectance of 220 to 390 nm. Two kinds of yellow low UV reflectors having a transmittance of 3.7% and a transmittance of 13% in the vicinity of the transmittance of the light wavelength component of 380 to 600 nm are used. The capture unit 6 was a pressure-sensitive adhesive applied to the surface of the reflector in both cases of a commercially available yellow reflector and a yellow low UV reflector. The experiment was conducted in the house for 7 days, and the lamp was turned on during the day from sunrise to sunset.

上記実験の結果、反射率が２２０〜３９０ｎｍの光波長成分の反射率が３．８％の黄色の低ＵＶ反射板は、市販黄色反射板に比べて約４倍の誘引効果であった。また、反射率が２２０〜３９０ｎｍの光波長成分の反射率が３．７％であり、かつ、３８０〜６００ｎｍの光波長成分の透過率付近における透過率が１３％である黄色の低ＵＶ反射板は、市販黄色反射板に比べて約６倍の誘引効果であった。そのため、本実施形態の害虫防除装置１は、太陽光が光反射誘引部４を透過することで、光反射誘引部４の太陽に面していない側の面から可視光が照射されるので、この太陽に面していない側の面においても昼行性農業害虫を誘引できるために、日中に昼行性農業害虫をより大量に誘引して捕獲することができる。   As a result of the above experiment, the yellow low UV reflector having a reflectance of 3.8% for the light wavelength component having a reflectance of 220 to 390 nm has an attracting effect about four times that of the commercially available yellow reflector. Moreover, the reflectance of the light wavelength component having a reflectance of 220 to 390 nm is 3.7%, and the transmittance of the light wavelength component having a reflectance of 380 to 600 nm is 13%. The attracting effect was about 6 times that of a commercially available yellow reflector. Therefore, the pest control apparatus 1 of the present embodiment allows visible light to be irradiated from the surface of the light reflection attraction unit 4 that does not face the sun by allowing sunlight to pass through the light reflection induction unit 4. Since the diurnal agricultural pests can be attracted even on the surface not facing the sun, the diurnal agricultural pests can be attracted and captured in a larger amount during the day.

なお、本発明は、上記の実施形態の構成に限られず、発明の要旨を変更しない範囲で種々の変形が可能である。例えば、ＵＶ−Ｂ及びＵＶ−Ｃの照度が強い場合に、人体に害を与える虞があるので、遮光板や人感センサスイッチをハウス内に設置し、それらを害虫防除装置１と電気的に接続させて、光照射部２の光が作業者に照射されないように配光を制御するようにしても構わない。この制御により、ハウス内の作業者の安全確保を図ることが可能となる。   In addition, this invention is not restricted to the structure of said embodiment, A various deformation | transformation is possible in the range which does not change the summary of invention. For example, when the illuminance of UV-B and UV-C is strong, there is a risk of harming the human body. Therefore, a light-shielding plate and a human sensor switch are installed in the house, and they are electrically connected to the pest control apparatus 1. The light distribution may be controlled so as to prevent the worker from being irradiated with the light from the light irradiation unit 2. This control makes it possible to ensure the safety of workers in the house.
