- the arrangement of is the same as the arrangement shown in FIG. 18). All the light sources installed in the same manner were turned on for about 10 minutes, and the number of insects captured by each lighting device was counted for a total of 20 minutes of the two lightings. The test was conducted twice in August 2020, and the number of captured insects was calculated as an average value. In addition, the insect attraction inhibition rate and the insect attraction rate were calculated by the above mathematical formulas in the same manner as in the 2019 test. The test results of each example and comparative example are shown below. From the above test results, the configuration of Example 8 in which the insect attracting light is irradiated within the range of the dark curtain provided assuming the structure is the configuration and structure of Example 9 in which the insect attracting light is irradiated even outside the range of the dark curtain.

- the insect attracting inhibition rate was slightly reduced and the insect attracting rate was slightly increased. It is considered that this is because the directivity angle of the insect attracting light source is increased and the irradiation space of the insect attracting light is expanded.
- Example 13 had the same insect attraction prevention rate as that of Example 14 having the same configuration as that of Example 13 except that a blackout curtain assuming a structure was not provided, but the insect attraction rate was higher. It has decreased. It was confirmed that the insect repellent effect can be enhanced by irradiating the structure with the insect attracting light even when the directivity angle of the insect attracting light source is increased.

Abstract
Description
しかし、人為的に昆虫を駆除することに対して、近年では、自然生態系の保全という観点から望ましくないとの考えが示されている。 It is generally known that insects have the property of moving toward the stimulus of light, that is, phototaxis, and many methods and devices for attracting and exterminating insects using this property have been proposed, and sports facilities. , Stadiums, stores, factories, etc.
However, in recent years, it has been suggested that artificially exterminating insects is not desirable from the viewpoint of conservation of natural ecosystems.
これらの低誘虫又は防虫光源を利用した方法及び装置は、昆虫が積極的に誘引されないようにして所定の場所への昆虫の侵入を低下させるため、自然生態系の保全という観点から望ましい手段である。
しかしながら、これらの低誘虫又は防虫光源を利用する方法及び装置では、低誘虫又は防虫光源を設置した場所の周辺に他の光源が存在しない場合には、昆虫が僅かな光刺激に反応してしまい、低誘虫又は防虫光源を設置した場所の周辺に飛来して来る昆虫が多くなるという問題がある。 On the other hand, an LED lamp (for example, Patent Document 1) that emits low insect attracting light that does not include wavelengths in the ultraviolet region or insectproof light that does not include wavelengths in the ultraviolet region and visible light region that insects are sensitive to, and insects are sensitive. Using a film, sheet, cover, yellow colorant, etc. that blocks light in the wavelength range, low insect attracting light or insect resistant light is extracted from the light emitted from fluorescent lamps, metal halide lamps, LED lamps, etc. (For example,
Methods and devices that utilize these low insect attracting or insect repellent light sources are desirable means from the viewpoint of conservation of natural ecosystems because they prevent insects from being actively attracted and reduce the invasion of insects into a predetermined place. ..
However, in the methods and devices using these low insect repellent or insect repellent light sources, the insects react to a slight light stimulus when there is no other light source around the place where the low insect repellent or insect repellent light source is installed. There is a problem that the number of insects flying around the place where the low insect attracting or insect repellent light source is installed increases.
しかしながら、このシステムで照明用光源として使用される青色光メタルハライドランプは、360°の全方向(反射板なし)又は180°の範囲で(反射板あり)紫外線を放射し、反射板を有するランプでも球技用練習場の外に向けて紫外線を放射するように設置されている。このため、低誘虫又は防虫光源による誘虫阻止効果を補強するという目的とは無関係な昆虫をも誘引するという問題がある。すなわち、低誘虫又は防虫光源の周囲に飛来した昆虫のみならず、球技用練習場の外にいた昆虫も誘引してしまうため、球技用練習場内に飛来する昆虫の数が増大し、メタルハライドランプと低誘虫放電ランプが近接する場合や、球技用練習場内の昆虫が多い場合には、利用者が位置する領域にまで昆虫が飛来することがある。また、球技用練習場内に飛来する昆虫が増加するために、利用者に不快感を生じさせてしまう。 On the other hand, in the lighting system of the practice field for ball games, a low insect attracting discharge lamp is used as a light source for illuminating the area used by the user, and a blue light metal halide lamp is used as a light source for illuminating the area where the user's hit ball flies. A lighting system characterized by using the above has been proposed (
However, the blue light metal halide lamp used as a light source for illumination in this system emits ultraviolet rays in all directions of 360 ° (without reflector) or in the range of 180 ° (with reflector), even a lamp having a reflector. It is installed so as to radiate ultraviolet rays toward the outside of the ball game practice area. Therefore, there is a problem of attracting insects unrelated to the purpose of reinforcing the insect attracting effect of the low insect attracting or insect repellent light source. In other words, not only insects that have flown around the low insect or insect repellent light source, but also insects that are outside the ball game practice field are attracted, so the number of insects that fly into the ball game practice field increases, and the metal halide lamp Insects may fly to the area where the user is located when the low insect repellent discharge lamp is in close proximity or when there are many insects in the ball game practice area. In addition, the number of insects flying into the ball game practice area increases, which causes discomfort to the user.

The insect attracting light source includes an ultraviolet emitting LED having a directivity angle of 45 ° to 120 ° and a maximum peak wavelength of 340 to 400 nm, and is installed at a distance of 10 m or more from the low insect attracting or insect repellent light source. Provided is a method of irradiating an insect light toward a light source. In this embodiment, the insect attractant light source is preferably installed at a distance of 10 m to 15 m from the low insect attractant or insect repellent light source.
低誘虫又は防虫光源としては、例えば、
図4(a)に示すような、紫外線領域の波長を殆ど又は全く含まない光を発する昼白色LED光源、又は紫外線領域及び誘虫効果のある可視光領域の波長を殆ど又は全く含まない光を発する黄緑系LED光源(これらは指向性を有する)、
図4(b)に示すような、蛍光灯、メタルハライドランプ、LED光源などから発せられた光を、紫外線領域又は更に誘虫効果のある可視光領域をカットするフィルター又はシートを通して、低誘虫又は防虫光を発する光源システム、
図4(c)に示すような、蛍光灯、メタルハライドランプ、LED光源などを、紫外線領域又は更に誘虫効果のある可視光領域をカットする色素(例えば、黄色系色素)で覆って、低誘虫又は防虫光を発する光源システム、および
図4(d)に示すような、蛍光灯、メタルハライドランプ、LED光源などを、紫外線領域又は更に誘虫効果のある可視光領域をカットするフィルムで覆って、低誘虫又は防虫光を発する光源システムが挙げられる。 In the present specification, "low insect attracting light" means light containing little or no ultraviolet region having a wavelength of 340 nm to 400 nm, and "insect-proof light" means light having almost no ultraviolet region and visible light region having a wavelength of 340 nm to 480 nm. Or it means light that does not contain at all. For example, as shown in FIG. 16, "low insect attracting light" it does not include the 5 W / m 2 or more peaks in the ultraviolet region of wavelength 340 nm ~ 400 nm, preferably free of 2μW / m 2 or more peaks. Further, "insect light" does not include the 5 W / m 2 or more peaks in the ultraviolet region and the visible light wavelength region of 340 nm ~ 480 nm, preferably free of 2μW / m 2 or more peaks.
As a low insect attracting or insect repellent light source, for example,
A neutral white LED light source that emits light that contains little or no wavelength in the ultraviolet region, as shown in FIG. 4A, or emits light that emits light that contains little or no wavelength in the ultraviolet region and the visible light region that has an insect attracting effect. Yellow-green LED light sources (these are directional),
Light emitted from fluorescent lamps, metal halide lamps, LED light sources, etc., as shown in FIG. 4B, is passed through a filter or sheet that cuts the ultraviolet region or the visible light region that has an insect attracting effect, and has low insect attracting or insect repellent light. Light source system,
Fluorescent lamps, metal halide lamps, LED light sources, etc., as shown in FIG. 4C, are covered with a dye (for example, a yellowish dye) that cuts an ultraviolet region or a visible light region having an insect attracting effect to reduce insect attraction or A light source system that emits insect-proof light, and a fluorescent lamp, metal halide lamp, LED light source, etc. as shown in FIG. 4 (d) are covered with a film that cuts an ultraviolet region or a visible light region that has an insect attracting effect to reduce insect attraction. Alternatively, a light source system that emits insect-proof light can be mentioned.
低誘虫又は防虫光源は、様々な場所に設置することができ、例えば、工場や店舗等の建屋内(図3の(a)参照)、当該建屋内の一部の区画又は部屋の中(図3の(b)参照)、当該建屋とその外の空間との境界(図3の(c)参照)、当該建屋の周辺(図3の(d)参照)、或いはゴルフ練習場や打撃練習場の競技者利用空間、駐車場、野外運動施設などの外に開放されている特定範囲の空間(図3の(e)参照)に設置することができる。
図3の(a)の例では、防虫領域は、工場や店舗等の建屋であり、図3の(b)の例では、防虫領域は、建屋の一部の区画又は部屋である。また、図3の(c)及び図3の(d)の例では、防虫領域は、建屋とその周辺である。この例では、建屋の周辺及び/又は建屋を照らすことが想定されるが、建屋の周辺が低誘虫又は防虫光で照らされると、建屋周辺への昆虫の積極的な誘引は抑制され、その結果、建屋への昆虫の侵入が抑制される。この例では、建屋内の低誘虫又は防虫光源の設置は必須ではなく、建屋内には低誘虫又は防虫光源を設置しない場合もある。従って、これらは、低誘虫又は防虫光源を、防虫領域の一部に設置する例に該当する。また、図3の(e)例では、防虫領域は、通常、利用者が利用する場所である。 A low insect repellent or insect repellent light source provides light in areas where illumination of the insect repellent area is required, while preventing active attraction of insects to the insect repellent area. Therefore, "around the low insect repellent or insect repellent light source" is included in the insect repellent area.
The low insect attractant or insect proof light source can be installed in various places, for example, in a building such as a factory or a store (see (a) in FIG. 3), or in a part of a section or room in the building (Fig. 3 (b)), the boundary between the building and the space outside it (see (c) in Fig. 3), the area around the building (see (d) in Fig. 3), or a driving range or driving range. It can be installed in a specific range of space (see (e) in FIG. 3) that is open to the outside, such as a space used by athletes, a parking lot, and an outdoor sports facility.
In the example of FIG. 3A, the insect repellent area is a building such as a factory or a store, and in the example of FIG. 3B, the insect repellent area is a part or room of a building. Further, in the example of FIG. 3C and FIG. 3D, the insect repellent area is the building and its surroundings. In this example, it is assumed that the area around the building and / or the building is illuminated, but when the area around the building is illuminated with low insect or insect repellent light, the active attraction of insects to the area around the building is suppressed, and as a result. , Insects invasion into the building is suppressed. In this example, it is not essential to install a low insect repellent or insect repellent light source in the building, and there are cases where a low insect repellent or insect repellent light source is not installed in the building. Therefore, these correspond to an example in which a low insect repellent or insect repellent light source is installed in a part of the insect repellent area. Further, in the example (e) of FIG. 3, the insect repellent area is usually a place used by the user.
本願明細書において「誘虫光」とは、波長340~400nmの紫外線領域の光を意味し、好ましくは、340~400nmの範囲に最大ピーク波長を有する光を意味する。誘虫光源としては、前記紫外線領域のみを放射する光源であってもよく、紫外線と可視光を放射する光源であってもよい。誘虫光源はまた、紫外線を放射する光源と可視光を放射する光源を組み合わせた光源でもよい。
昆虫の中には、可視光に対する感度が高い昆虫もあり、紫外線に可視光をブレンドすることにより、様々な種類の昆虫をより効果的に誘虫光源の方に誘引することができる場合がある。 In the system or the like according to the embodiment of the present invention, the insect repellent light source is installed away from the insect repellent area, and the insect repellent light is emitted toward the insect repellent area. Further, in a system or the like according to another embodiment, the insect attracting light source is installed away from the low insect attracting or insect repellent light source, and the insect attracting light is radiated toward the low insect attracting or insect repellent light source.
As used herein, the term "insect light" means light in the ultraviolet region having a wavelength of 340 to 400 nm, preferably light having a maximum peak wavelength in the range of 340 to 400 nm. The insect attracting light source may be a light source that emits only the ultraviolet region, or may be a light source that emits ultraviolet rays and visible light. The insect attracting light source may also be a light source that is a combination of a light source that emits ultraviolet rays and a light source that emits visible light.
Some insects are highly sensitive to visible light, and by blending visible light with ultraviolet light, it may be possible to more effectively attract various types of insects toward the insect attracting light source.
他方、防虫領域又は低誘虫若しくは防虫光源から離れすぎると、誘虫光の強度が低くなり、誘引効果が十分に発揮し得なくなるので、防虫領域又は防虫若しくは低誘虫光源の周辺にいる昆虫を誘引し得る距離で設置する必要がある。また、防虫領域から離れるにつれ、同じ指向角度の誘虫光源を用いても照射範囲が広くなるので、目標とする防虫領域の範囲と用いる誘虫光源の指向角度に応じて、適切な距離を選択する必要がある(この点は後で詳細に説明する)。
このような点から、誘虫光源と防虫領域又は低誘虫若しくは防虫光源との間の距離は、30m以下とすることが好ましく、20m以下とすることがより好ましく、15m以下とすることが特に好ましい。また、設置環境によっては、10m以下としてもよい。
誘虫光源と防虫領域又は低誘虫若しくは防虫光源との距離はまた、建屋等の構造物に向けて誘虫光を放射する場合には、誘虫光が照射される壁の反射率又は反射光の強度を考慮して決めることが好ましい。具体的には、反射光の強度が高い場合には、反射した誘虫光により誘虫効果を生じさせる恐れがあるので、反射率が10%以下となる建屋等の構造物が本発明の適用対象として好ましく選択される。また、同様の観点で、建屋等の構造物に誘虫光を照射した際に、反射光の紫外線領域のピーク波長強度が壁から10cmの位置で10μW/m2以下、好ましくは5μW/m2以下となる距離に誘虫光源を設置することが好ましい。 It is preferable that the insect attracting light source is installed in a place away from the area or a low insect attracting or insect repellent light source so that the insects attracted by the insect attracting light source do not fly to the insect repellent area. From such a point, the distance between the insect attracting light source and the insect repellent region or the low insect attracting or insect repellent light source is preferably 5 m or more, and more preferably 10 m or more.
On the other hand, if the distance from the insect repellent area or the low insect repellent or low insect repellent light source is too large, the intensity of the insect repellent light becomes low and the attracting effect cannot be sufficiently exerted. It is necessary to install it at the distance you can get. In addition, as the distance from the insect repellent area increases, the irradiation range becomes wider even if the insect repellent light source with the same directivity angle is used. (This point will be explained in detail later).
From such a point, the distance between the insect repellent light source and the insect repellent region or the low insect repellent or insect repellent light source is preferably 30 m or less, more preferably 20 m or less, and particularly preferably 15 m or less. Further, depending on the installation environment, it may be 10 m or less.
The distance between the insect attractant light source and the insect repellent area or the low insect attractant or insect repellent light source also determines the reflectance or the intensity of the reflected light of the wall irradiated with the insect attractant light when the insect attractant light is radiated toward a structure such as a building. It is preferable to consider and decide. Specifically, when the intensity of the reflected light is high, the reflected insect attracting light may cause an insect attracting effect. Therefore, a structure such as a building having a reflectance of 10% or less is an object of the present invention. It is preferably selected. For the same viewpoint, when irradiated with insect attracting light to the structure of the building or the like, the peak wavelength intensity of the ultraviolet region of the reflected light at the position of 10cm from the
他方、本発明のシステム等では、防虫領域以外の空間に向けて誘虫光が放射されないようにすることが重要である。このような空間が多くなると、低誘虫又は防虫光の誘虫阻止効果を補強する目的とは無関係な昆虫を誘引してしまい、侵入を防止することが意図される領域へ昆虫が飛来する可能性を高めることになる。 In one embodiment of the present invention, the insect attracting light may be emitted toward the entire insect repellent area or a part thereof. However, even when radiating to a part, it is preferable to radiate to as wide a range as possible. In addition, when a structure such as a store or factory is included in the insect repellent area, it is not necessary to irradiate the structure such as a store or factory with insect attracting light, but even in this case, the insect repellent area is "directed". Corresponds to radiating. Also, in another embodiment of the invention, the insect attracting light is emitted towards a low insect attracting or insect repellent light source. The attracting light from one insect attracting light source emits "toward" the low insect attracting or insect repellent light source whether it is irradiated to one low insect attracting or insect repellent light source or to a plurality of low insect attracting or insect repellent light sources. , Corresponds to.
On the other hand, in the system of the present invention and the like, it is important to prevent the insect attracting light from being emitted toward the space other than the insect repellent area. When such a space increases, insects that have nothing to do with the purpose of reinforcing the insect repellent effect of low insect repellent or insect repellent light are attracted, and there is a possibility that insects may fly to the area intended to prevent invasion. It will be enhanced.
図1は、工場及びトラックヤードエリアが昆虫の侵入を防止するための領域として設定されている実施形態を示す。図1に示す実施形態では、複数の低誘虫又は防虫光源が、工場の搬出入口を有する壁に一定間隔で配置され、トラックヤードエリアを含む工場周辺が低誘虫光又は防虫光で照らされている。この結果、工場周辺に昆虫を積極的に誘引しないようにしている。他方、複数の誘虫光源が、工場の搬出入口を有する壁から約10~15m(トラックヤードから7~12m)離れて設置されている。設置した誘虫光源は、すべて同じ(例えば、45°)指向角度を有し、等間隔で設置されており、工場及びその周辺の一定範囲に向けて誘虫光を放射している。この結果、トラックヤードエリアを含む工場周辺に飛来した昆虫は、誘虫光に反応して誘虫光源に誘引され、工場周辺により昆虫のいない環境が形成され、これにより昆虫が工場内部へ侵入することをより確実に防止することができる。 Here, a typical embodiment of the present invention will be described.
FIG. 1 shows an embodiment in which a factory and a truck yard area are set as areas for preventing the invasion of insects. In the embodiment shown in FIG. 1, a plurality of low insect attracting or insect repellent light sources are arranged at regular intervals on the wall having the entrance / exit of the factory, and the area around the factory including the truck yard area is illuminated with the low insect attracting light or the insect repellent light. .. As a result, we try not to actively attract insects around the factory. On the other hand, a plurality of insect attracting light sources are installed at a distance of about 10 to 15 m (7 to 12 m from the truck yard) from the wall having the entrance and exit of the factory. The installed insect attracting light sources all have the same (for example, 45 °) directivity angles and are installed at equal intervals, and emit insect attracting light toward a certain range in and around the factory. As a result, insects that have flown around the factory, including the truck yard area, are attracted to the insect light source in response to the insect light, creating an insect-free environment around the factory, which prevents insects from invading the inside of the factory. It can be prevented more reliably.
この試験は、低誘虫又は防虫光源、並びに種々の指向角度を有するUVランプ又はそれと昼白色LEDとの組み合わせで構成される誘虫光源を組み合わせて行い、得られた各光源での昆虫の捕獲数から誘虫阻止率及び誘虫率を求めた。各実施例及び比較例での光源の組み合わせを以下の表に示す。 1. 2019 Insect Capture Test This test was conducted by combining a low insect attracting or insect repellent light source, and an insect attracting light source composed of a UV lamp having various pointing angles or a combination thereof and a neutral white LED, and each light source obtained. The insect repellent prevention rate and the insect repellent rate were calculated from the number of insects caught in the plant. The combinations of light sources in each example and comparative example are shown in the table below.
図18に示す通り、この照明装置に、まず、上述した低誘虫又は防虫光源(図示せず)を組み込み、圃場中に、10m間隔で2台配置した。各照明装置15から5m離れた中間点で、暗幕18を張り、各照明装置15からの光が、他の照明装置側15に漏れないようにした。次いで、2つの照明装置15のうち1つに対峙させて、10mまたは15mの距離をあけて、各誘虫光源を組み込んだ照明装置16を配置した。他の1つには誘虫光源を組み込んだ照明装置16を対峙させなかった。設置した光源をすべて約10分間点灯し、各照明装置に取り付けられた粘着シートによって昆虫を捕獲した。その後、誘虫光源を有する照明装置16を移動し、低誘虫又は防虫光源を組み込んだ別の照明装置に対峙させた(1回目の点灯時における各照明装置の配置を図18の左側に示し、2回目の点灯時における各照明装置の配置を図18の右側に示す)。設置した光源をすべて約10分間点灯し、2回の点灯の合計20分間に各照明装置に捕獲された昆虫の数をカウントした。試験は、2019年の7月と9月に2回行い、捕獲虫数は、平均値として求めた。誘虫阻止率および誘虫率は、以下に示す数式により求めた。 The insect capture test was carried out using the

The test results of each example and comparative example are summarized in the table below.
この試験では、防虫領域に構造物を含む場合を想定して、当該構造物と仮定して設けた暗幕及び誘虫光源の設置条件について誘虫阻止率及び誘虫率を調べた。各実施例及び比較例での試験条件は、以下の通りである。
また、各実施例及び比較例の試験手順は、基本的に2019年の試験と同様にして行った。図17に示す照明装置を用い、まず、上述した低誘虫又は防虫光源を組み込んだ照明装置を、圃場中に、10m間隔で2台配置し、構築物を仮定して暗幕を設置する場合には、各低誘虫又は防虫光源のすぐ後ろに、4.1m又は8.2mの暗幕を、各低誘虫又は防虫光源が暗幕の幅の中点に位置するように設置した。次いで、2台照明装置間の直線上で各照明装置から5m離れた中間点で、暗幕を張り、各照明装置からの光が、他の照明装置側に漏れないようにした。次いで、実施例8乃至14では、2つの照明装置のうち1つに対峙させて、10mまたは5mの距離をあけて、各誘虫光源を組み込んだ照明装置を配置した。他方、比較例4では、誘虫光源を組み込んだ照明装置を低誘虫又は防虫光源と対峙させずに、低誘虫又は防虫光源と反対の方向に向けて設置した。設置した光源をすべて約10分間点灯し、各照明装置に取り付けられた粘着シートによって昆虫を捕獲した。その後、誘虫光源を有する照明装置を移動し、低誘虫又は防虫光源を組み込んだ別の照明装置に対峙させた(1回目の点灯時における各照明装置の配置と2回目の点灯時における各照明装置の配置は、図18に示す配置と同様である)。同様に設置した光源をすべて約10分間点灯し、2回の点灯の合計20分間に各照明装置に捕獲された昆虫の数をカウントした。試験は、2020年8月に2回行い、捕獲虫数は、平均値として求めた。また、誘虫阻止率および誘虫率は、2019年の試験と同様にして上記数式により求めた。
各実施例及び比較例の試験結果を以下に示す。
上記の試験結果から、構造物を想定して設けた暗幕の範囲内で誘虫光を照射する実施例8の構成が、暗幕の範囲外へも誘虫光が照射される実施例9の構成や構造物を想定した暗幕を設けなかった実施例10の構成に比べ、誘虫阻止率がやや高くなり、誘虫率は顕著に減少することが理解される。また、誘虫光源を低誘虫又は防虫光源に対峙させず低誘虫又は防虫光源とは反対の方向に向けた比較例4の構成では、誘虫阻止率がコントロールに近似する低値となり、誘虫率は、大きく上昇した。
また、80°の指向角度を有する誘虫光源で、幅8.2mの暗幕のほぼ範囲内で誘虫光を照射する実施例13の構成は、45°の指向角度を有する誘虫光源で、幅4.1mの暗幕のほぼ範囲内で誘虫光を照射する実施例11の構成に比べ、誘虫阻止率がやや低下し、誘虫率がやや上昇した。これは、誘虫光源の指向角度が大きくなることで、誘虫光の照射空間が広がったことによるものと考えられる。他方、実施例13の構成は、構造物を想定した暗幕を設けない以外は、実施例13と同じ構成の実施例14の構成に比べ、誘虫阻止率は同程度であったものの、誘虫率が低下した。誘虫光源の指向角度が大きくした場合であっても、構造物に向けて誘虫光を照射することで防虫効果を高め得ることが確認された。 In the table, the "UV lamp with a directional angle of 45 °" and the "UV lamp with a directional angle of 80 °" are UV-radiating LED lamps (straight tube UV-LED, manufactured by Iida Lighting Co., Ltd.) with a maximum peak wavelength of 365 nm. The lamp is adjusted to 45 ° and 80 °. In addition, an insect repellent LED lamp (Magic Optron LED, manufactured by Taisei Fine Chemical Co., Ltd.) was used as a low insect repellent or insect repellent light source.
In addition, the test procedure of each Example and Comparative Example was basically the same as that of the 2019 test. When using the lighting device shown in FIG. 17 and first arranging two lighting devices incorporating the above-mentioned low insect attractant or insect repellent light source in the field at intervals of 10 m and installing a blackout curtain assuming a structure, Immediately behind each low insect or insect repellent light source, a 4.1 m or 8.2 m blackout was placed so that each low insect or insect repellent light source was located at the midpoint of the width of the blackout. Next, a blackout curtain was set up at an
The test results of each example and comparative example are shown below.
From the above test results, the configuration of Example 8 in which the insect attracting light is irradiated within the range of the dark curtain provided assuming the structure is the configuration and structure of Example 9 in which the insect attracting light is irradiated even outside the range of the dark curtain. It is understood that the insect attraction prevention rate is slightly higher and the insect attraction rate is significantly reduced as compared with the configuration of Example 10 in which the blackout curtain is not provided assuming an object. Further, in the configuration of Comparative Example 4 in which the insect attracting light source is not confronted with the low insect attracting or insect repellent light source and is directed in the direction opposite to the low insect attracting or insect repellent light source, the insect attracting inhibition rate becomes a low value close to the control, and the insect attracting rate is high. It rose significantly.
Further, the configuration of Example 13 in which the insect attracting light source having a directivity angle of 80 ° irradiates the insect attracting light within a substantially range of a blackout curtain having a width of 8.2 m is an insect attracting light source having a directivity angle of 45 ° and a width of 4. Compared with the configuration of Example 11 in which the insect attracting light was irradiated within a substantially range of a 1 m dark curtain, the insect attracting inhibition rate was slightly reduced and the insect attracting rate was slightly increased. It is considered that this is because the directivity angle of the insect attracting light source is increased and the irradiation space of the insect attracting light is expanded. On the other hand, the configuration of Example 13 had the same insect attraction prevention rate as that of Example 14 having the same configuration as that of Example 13 except that a blackout curtain assuming a structure was not provided, but the insect attraction rate was higher. It has decreased. It was confirmed that the insect repellent effect can be enhanced by irradiating the structure with the insect attracting light even when the directivity angle of the insect attracting light source is increased.
