Description

[0001] This invention patent application is a divisional application of the invention patent application with national application number 202080033611.X (international application number PCT / JP2020 / 001656) and invention name “Insect Trap”. Technical Field

[0002] The present invention relates to an insect trap for driving away pests in a farm in order to reduce the pests' eating of cultivated crops. Background Art

[0003] In orchards where fruit trees such as strawberries and peaches are grown, or farms where crops such as spinach and chrysanthemums are grown, pests need to be driven away in order to reduce their eating by fruit trees and crops.

[0004] Therefore, the following methods have been proposed: for example, using an attracting light source using a blue fluorescent lamp to attract the pests, killing them by electrical stimulation, or attracting and capturing them by a blower.

[0005] For example, in Patent Document 1 (Japanese Patent Laid-Open No. 2005-229997), Figure 1 In this connection, an insect trap is disclosed, which is composed of a light source for attracting 2 and reflectors 4 and 5, and further a flying unit and a killing and capturing unit composed of a motor 6, a fan 7 and a white insect catching net 8. In such an insect trap, the reflectors 4 and 5 are used to make insects attracted by the light of the light source 2 slide down, and the blowers 6 and 7 located therebelow attract and kill the insects so that the insects fall into the capturing net 8.

[0006] [Patent Document 1] Japanese Patent Application Publication No. 2005-229997 Summary of the invention

[0007] [Problems to be Solved by the Invention]

[0008] In conventional insect traps, there is a problem that the light from the attracting light source 2 cannot reach the area below the reflector 5, and the probability that the pests in this area are attracted by the attracting light source 2 and captured / repelled becomes very small.

[0009] Previous insect traps had the following problem: even if the number of uncaptured pests was very small, depending on the type of pest, some pests reproduced very quickly, and there were many cases where their numbers increased exponentially over time. Therefore, even if the probability of extermination was slightly reduced, the damage to fruit trees, vegetables, and crops would increase.

[0010] In addition, in tall crops, there are problems such as cold air stagnating near the roots, which increases the incidence of diseases and makes it difficult to produce fruits near the roots, resulting in reduced production. However, conventional insect traps have not solved such problems.

[0011] [Methods for solving the problem]

[0012] The present invention is completed to solve the above-mentioned problems. The insect trap of the present invention is characterized in that it includes: an attracting light source, which emits light to attract insects; a mortar-shaped portion, which is arranged vertically below the attracting light source, and the opening diameter decreases toward the vertical direction; a cylindrical portion, which is arranged vertically below the mortar-shaped portion and extends from the mortar-shaped portion; a fan, which generates an airflow that is sucked into the cylindrical portion from the opening of the mortar-shaped portion; a transparent long cylindrical portion, which is arranged vertically below the cylindrical portion to allow light to pass through; and a net, which is arranged vertically below the transparent long cylindrical portion to capture insects.

[0013] Furthermore, the insect trap of the present invention is characterized in that an attractant for attracting insects is arranged near the mortar-shaped portion.

[0014] Furthermore, the insect trap of the present invention is characterized in that an adhesive is applied to the transparent elongated cylindrical portion.

[0015] Furthermore, the insect trap of the present invention is characterized in that a cylindrical protective net is arranged so as to surround the outer circumference of the transparent long cylindrical portion.

[0016] In addition, the insect trap of the present invention is characterized in that, on the protective net, the adhesive sheet is arranged on the outside or inside of the protective net.

[0017] In addition, the insect trap of the present invention is characterized in that the attracting light source has a radiation wavelength region of 500 nm to 750 nm, and has a maximum radiation peak wavelength in the range of 540 nm to 630 nm.

[0018] In addition, the insect trap of the present invention is characterized in that it also has an auxiliary light source having a maximum radiation peak at a radiation wavelength of approximately 565 nm.

[0019] In addition, the insect trap of the present invention is characterized in that the attracting light source has a radiation wavelength region of 300 nm to 500 nm, and has a maximum radiation peak wavelength in the range of 340 nm to 450 nm.

[0020] In addition, the insect trap of the present invention is characterized in that it further includes an auxiliary light source having a maximum radiation peak wavelength in a radiation wavelength of not less than 340 nm and not more than 450 nm.

[0021] In addition, the insect trap of the present invention is characterized in that it further includes an auxiliary light source having a maximum radiation peak wavelength at a radiation wavelength of not less than 540 nm and not more than 630 nm.

[0022] [Effects of the Invention]

[0023] The insect trap of the present invention has a transparent elongated cylindrical portion that allows light to pass therethrough vertically below the cylindrical portion. According to the insect trap of the present invention, since the light from the attracting light source also reaches the area on the lower side via the transparent elongated cylindrical portion, the pests located in the area are attracted by the attracting light source and captured / expelled, thereby further improving the probability of expelling the pests and suppressing the damage of the pests to fruit trees, vegetables and crops.

[0024] Furthermore, according to the insect trap of the present invention, warm air can be supplied from the transparent long cylindrical portion to the vicinity of the roots of crops, the incidence of crop diseases can be reduced, and crops can be made strong near the roots, thereby increasing the yield of crops.

[0033] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Figure 1 1 is a diagram for explaining the outline of the insect trap 100 according to the first embodiment of the present invention. Figure 2 It is a figure explaining the insect catching effect of the insect trap 100 according to the first embodiment of the present invention.

[0034] The insect trap 100 is assumed to be used by being suspended by, for example, a hanging wire 110. The main structure of the insect trap 100 is a substantially symmetrical structure centered on an imaginary axis OO' through which the hanging wire 110 passes. For example, the attracting light source 210 is substantially annular.

[0035] The conical portion 150 is suspended from the down-hanging wire 110 . Moreover, the chemical substance dispensing unit 130 is attached to the down-hanging wire 110 above the conical portion 150 .

[0036] Fixing metal fittings 151 are provided at three locations on the upper side of the peripheral surface of the conical portion 150 so as to extend from the peripheral surface. The three fixing metal fittings 151 support the attracting light source 210 .

[0037] In addition, the number of the fixing fittings 151 provided on the peripheral surface of the conical portion 150 is not limited to three as described above.

[0038] The above-mentioned attracting light source 210 is a fluorescent tube that emits light through a stabilizer (not shown) and has a predetermined radiation wavelength region. In addition, in the first embodiment, the description is based on the example of using a fluorescent tube as the attracting light source 210, but other light sources such as incandescent lamps, mercury lamps, sodium lamps, LEDs, etc. can also be used as the attracting light source. If the attracting light source 210 emits light, it functions as a light source for attracting pests.

[0039] Support rods (not shown) extend from three locations at the bottom of the conical portion 150, and the mortar-shaped portion 160 and the conical portion 150 are connected by these support rods. The space between the bottom of the conical portion 150 and the mortar-shaped portion 160 except for the support rods becomes a gap, and pests can be attracted from the gap, or light from the attracting light source 210 can enter the lower side. The cylindrical portion 170 extends vertically downward from the bottom of the mortar-shaped portion 160.

[0040] The mortar-shaped portion 160, the conical portion 150, the cylindrical portion 17, etc. are made of materials such as iron or stainless steel. Furthermore, it is preferable that each of these components is coated with a weather-resistant paint.

[0041] In addition, a transparent elongated cylindrical portion 180 made of a synthetic resin material is installed on the lower side of the cylindrical portion 170. The light from the attracting light source 210 entering from the gap between the mortar-shaped portion 160 and the conical portion 150 irradiates the lower side of the insect trap 100 from the transparent elongated cylindrical portion 180 as the irradiation light t. In addition, a capture net 310 is installed vertically below the transparent elongated cylindrical portion 180. The attracted pests are captured and driven away by the capture net 310.

[0042] It is also a preferred embodiment to prepare the transparent long cylindrical portion 180 of different lengths and appropriately change the length of the transparent long cylindrical portion 180 to different lengths as the crop grows.

[0043] A fan 190 driven to rotate by a motor (not shown) is provided in the cylindrical portion 170. The rotation of the fan 190 generates an airflow in the gap between the conical portion 150 and the mortar-shaped portion 160 that sucks the mortar-shaped portion 160 vertically downward.

[0044] The pests attracted by the attracting light source 210 are guided to the capturing net 310 via the cylindrical portion 170 and the transparent long cylindrical portion 180 by the airflow generated by the fan 190 and sucked into the cylindrical portion 170 from the opening of the mortar-shaped portion 160 .

[0045] When the attracting light source 210 emits light, the oblique line portion of the conical portion 150 disposed vertically below the attracting light source 210 functions as a reflection surface, thereby forming reflected light r1.

[0046] In addition, when the attracting light source 210 emits light, the inner surface of the mortar-shaped portion 160 disposed vertically below the attracting light source 210 functions as a reflecting surface, thereby forming reflected light r2.

[0047] In addition, the attraction light source 210 emits light to form irradiation light t from the transparent elongated cylindrical portion 180. Pests in the area below the mortar-shaped portion 160 are also attracted by the attraction light source and are attracted by the airflow generated by the fan 190 and captured.

[0048] In this way, according to the insect trap 100 of the present invention, since the light from the attracting light source 210 also reaches the area on the lower side via the transparent long cylindrical portion 180, the pests located in this area are attracted by the attracting light source 210 and captured / expelled, thereby further improving the probability of expelling the pests and suppressing the damage of the pests to fruit trees, vegetables and crops.

[0049] In addition, since the irradiated light t has the same effect on crops as increasing the sunshine time, it can also contribute to increasing the yield of crops.

[0050] As the attracting light source 210, a light source having an emission wavelength range of 500 nm to 750 nm and a maximum emission peak wavelength range of 540 nm to 630 nm can be used. With such an attracting light source 210, whiteflies, grasshoppers, flies, and aphids can be efficiently attracted.

[0051] The attracting light source 210 having such spectral characteristics can be formed by forming a coating on the surface of a fluorescent tube (white fluorescent lamp; color temperature 4200K). The coating on the surface of the fluorescent tube functions as a filter, blocking the radiated light with a wavelength shorter than about 500nm and allowing the radiated light in the longer wavelength region to pass efficiently. Such a coating is formed by applying a mixture of a hydroxyl-containing acrylic resin and benzimidazolone, an epoxy resin, a varnish, a curing agent (isocyanate compound), and a diluent to the fluorescent tube.

[0052] The attracting light source 210 formed by applying the coating as described above is particularly preferably an attracting light source having two local emission peaks at emission wavelengths near 545nm and near 575nm, but the attracting light source 210 may also be a light source having two local emission peaks at emission wavelengths from near 500nm to near 650nm.

[0053] In addition, as the attracting light source 210, a light source having a radiation wavelength region of 300 nm to 500 nm or more and a maximum radiation peak wavelength region formed in a wavelength region of 340 nm to 450 nm or more may be used. As the attracting light source 210 having such spectral characteristics, a black light bulb, a black light fluorescent lamp, a black light LED, etc. may be used. According to such an attracting light source 210, it is possible to efficiently attract thrips, flies, noctuidae, stink bugs, and feather lice.

[0054] Here, in this specification, for example, when the peak wavelength is set to 545nm with high precision, a deviation of about ±15nm of the wavelength is also included. Thus, in this specification, the wavelength range is defined as the specified wavelength and the range of ±15nm of the wavelength. The reason for defining the wavelength as a range is that even for the same type of insects, there are differences based on regions, etc., and the insect catching effect of the wavelength of the light source, for example, varies from region to region.

[0055] Furthermore, in the first embodiment, the case where the attracting light source 210 has a substantially annular shape has been described, but in the insect trap 100 of the present invention, the shape of the light source is not limited to this.

[0056] In addition, in the first embodiment, one type of attracting light source 210 is provided as an attracting light source, but more types of attracting light sources may be used. For example, if two types of attracting light sources with different radiation wavelength regions are used as the attracting light source 210, the types of pests that can be attracted by the attracting light sources are increased, the probability of pest expulsion can be further improved, and the damage of pests to fruit trees, vegetables, and crops can be suppressed.

[0057] In addition, it is preferable to use a mesh size of about 0.1 mm to 0.3 mm for the capture net 310. Alternatively, the capture net 310 may be used in duplicate with mesh sizes of different sizes.

[0058] For example, as the capture net 310, a capture net with a mesh size of about 0.1 mm to 0.3 mm and a capture net with a mesh size of about 5 mm are also preferred embodiments. Even when a relatively large insect is captured, since the large mesh portion will not be bitten by the insect to form a hole, the captured pest will not escape from the net, which can further increase the probability of pest expulsion and inhibit pest damage to fruit trees, vegetables, and crops.

[0059] In the insect trap 100 of the first embodiment, a chemical substance arrangement portion 130 where chemical substances can be installed is provided on the downline 110. As the chemical substances arranged in the chemical substance arrangement portion 130, it is preferable to use an attractant such as a sex pheromone agent, an aggregation pheromone agent, or a lactic acid bacteria secretion agent that attracts pests. In this case, a synergistic effect with the attracting effect of the attracting light source 210 can be expected.

[0060] The location where the chemical substance dispensing section 130 is provided does not necessarily have to be the downline 110 , and may be any location as long as it can appropriately attract pests near the mortar-shaped section 160 .

[0061] On the other hand, an insect repellent may be used as the chemical substance disposed on the chemical substance disposing portion 130. In this case, even if undesirable insects are not allowed to approach the farm or orchard, the insects that damage crops can be captured / expelled based on the attracting effect of the attracting light source 210 on the insects.

[0062] In the first embodiment, the insect trap 100 is suspended by the downline 110 so that the imaginary axis OO' is parallel to the vertical direction. However, depending on the type of fruit trees, vegetables, and crops, the insect trap 100 can also be used in a manner such that the imaginary axis OO' of the insect trap 100 is parallel to the horizontal plane.

[0063] However, in crops with high height, there are problems such as the incidence of diseases increases due to cold air stagnation near the roots, and it is difficult to produce fruits near the roots, which reduces the production. The insect trap 100 involved in the present invention also has a structure in which the air (W) at a higher temperature layer sucked into the mortar-shaped part 160 is supplied to the vicinity of the roots of the crops by the fan 190. Figure 3 It is a figure explaining the air circulation effect of the insect trap 100 according to the first embodiment of the present invention.

[0064] like Figure 3As shown, the ability to supply warm air (W) even to the roots of tall crops largely depends on the use of the transparent long cylindrical portion 180 in the first embodiment. Although it depends on the crops, the transparent long cylindrical portion 180 is preferably 1 m or more.

[0065] According to the insect trap 100 of the present invention, warm air can be supplied from the transparent long cylindrical portion 180 to the vicinity of the roots of crops, the incidence of crop diseases can be reduced, and crops can be made strong near the roots, thereby increasing the yield of crops.

[0066] Next, other embodiments of the present invention will be described. Figure 4 It is a figure explaining the insect trap 100 of the second embodiment of the present invention. Figure 4 (A) is a diagram showing the vicinity of the transparent long cylindrical portion 180 of the insect trap 100 of the first embodiment described above, Figure 4 (B) is a diagram showing the vicinity of the transparent long cylindrical portion 180 of the insect trap 100 of the second embodiment. In the following description of other embodiments, the differences from the insect trap 100 of the first embodiment are mainly described. In addition, the characteristic points of the various other embodiments described below can also be combined with any embodiment of the insect trap 100 described in this specification.

[0067] There is no particular study on the transparent long cylindrical portion 180 itself of the insect trap 100 of the first embodiment, but an adhesive 270 is applied to the transparent long cylindrical portion 180 of the insect trap 100 of the second embodiment.

[0068] The case where the irradiation light t from the transparent elongated cylindrical portion 180 is formed by the light emission of the attracting light source 210 has been described. Pests are often caused to stay in the transparent elongated cylindrical portion 180 itself by such irradiation light t. Therefore, in the insect trap 100 of the second embodiment, the adhesive 270 is applied to the transparent elongated cylindrical portion 180, and pests are captured by the transparent elongated cylindrical portion 180 itself. In such a second embodiment, it is also assumed that pests are also captured in the capture net 310, and the number of pests captured as a whole can be increased by the capture amount in the adhesive 270 in addition to the capture amount in the capture net 310.

[0069] Next, other embodiments of the present invention will be described. Figure 51 is a diagram illustrating an insect trap 100 according to a third embodiment of the present invention. In the insect trap 100 according to the second embodiment, since an adhesive 270 is applied to the outer periphery of the transparent elongated cylindrical portion 180, leaves of crops or hair of agricultural workers may adhere to the adhesive 270. Therefore, in the third embodiment, a cylindrical protective net 280 is arranged so as to surround the outer periphery of the transparent elongated cylindrical portion 180. As a fixing unit for the protective net 280, an arm member (not shown) extending from the cylindrical portion 170 or the transparent elongated cylindrical portion 180 can be used. In addition, the mesh size of such a protective net 280 is preferably 5 mm to 10 cm.

[0070] According to such an embodiment, the number of captured pests as a whole can be increased by the capture amount in the adhesive 270 in addition to the capture amount in the capture net 310, and adhesion of leaves of crops, hair of agricultural workers, etc. can be prevented.

[0071] Next, other embodiments of the present invention will be described. Figure 6 1 is a diagram illustrating an insect trap 100 according to a fourth embodiment of the present invention. In the second and third embodiments, an adhesive 270 is applied to the outer periphery of the transparent elongated cylindrical portion 180. In contrast, in the insect trap 100 according to the fourth embodiment, a cylindrical protective net 280 is arranged so as to surround the outer periphery of the transparent elongated cylindrical portion 180, and an adhesive sheet 285 is wound around the protective net 280 from the outside. According to such an embodiment, there are advantages that pests lured by the irradiated light t are captured by the adhesive sheet 285, and such an adhesive sheet 285 can be easily replaced.

[0072] On the other hand, the adhesive sheet 285 may be disposed inside the protective net 280. Then, pests are captured by the adhesive sheet 285 inside the protective net 280. In this case, it becomes difficult to replace the adhesive sheet 285, but the probability of leaves of crops or hair of agricultural workers adhering to the adhesive sheet 285 can be reduced.

[0073] Next, other embodiments of the present invention will be described. Figure 7 It is a figure explaining the outline of the insect trap 100 which concerns on the 5th Embodiment of this invention.

[0074] The insect trap 100 of the fifth embodiment is different from the insect trap 100 of the first embodiment in that, in addition to the light source 200, an auxiliary light source 220 is disposed in the middle of the hanging line 110. In addition, in the present embodiment, the chemical substance dispensing unit 130 is disposed below the auxiliary light source 220, but the chemical substance dispensing unit 130 may be disposed above the auxiliary light source 220. Alternatively, the chemical substance dispensing unit 130 may be disposed on both sides of the upper side and the lower side of the auxiliary light source 220.

[0075] The auxiliary light source 220 is different from the light source 200 used in the first embodiment. The attracting light source 210 used in the first embodiment uses, for example, a fluorescent lamp with a predetermined coating applied thereto. The auxiliary light source 220 preferably uses an LED (Light Emitting Diode) element.

[0076] In addition, the auxiliary light source 220 is preferably arranged in the middle of the hanging line 110, for example, but the manner of arranging such an auxiliary light source 220 is not limited thereto. The auxiliary light source 220 uses a plurality of LED elements 223. Generally, the light emitted from the LED element 223 has directivity. If there is directivity, it is not possible to attract pests efficiently, and therefore, a transparent light-diffusing resin 230 is provided as a light-diffusing unit for diffusing the light emitted from the LED element 223. The light-diffusing means that can be used in the present invention is not limited to transparent resins, and light-guiding materials such as glass can also be used.

[0077] When a light source having a radiation wavelength range of 500 nm to 750 nm is used as the attracting light source 210, the auxiliary light source 220 used in the fifth embodiment preferably uses a light source having a maximum radiation peak at a radiation wavelength near 565 nm. In this case, the light source composed of the attracting light source 210 and the auxiliary light source 220 can more effectively guide whiteflies, thrips, aphids (Pterygota), miners, and flies.

[0078] On the other hand, when the above-mentioned attracting light source having a radiation wavelength range of 300 nm to 500 nm is used as the attracting light source 210, the auxiliary light source 220 used in the fifth embodiment preferably uses a light source having a maximum radiation peak wavelength of 340 nm to 450 nm. In this case, the light source composed of the attracting light source 210 and the auxiliary light source 220 can more effectively attract grasshoppers, flies, noctuids, stink bugs, and feather lice.

[0079] However, as the auxiliary light source 220, a light source having a maximum radiation peak wavelength of 540 nm to 630 nm may be used instead of a light source having a maximum radiation peak wavelength of 340 nm to 450 nm. Alternatively, a light source having a maximum radiation peak wavelength of both sides may be used as the auxiliary light source 220.

[0080] According to the insect trap 100 of the fifth embodiment as described above, in addition to the effect of the attraction light source 210 functioning as the main light source, the effect of the auxiliary light source 220 can be expected to increase the number of captured pests.

[0081] Next, other embodiments of the present invention will be described. Figure 8 It is a figure explaining the outline of the insect trap 100 which concerns on 6th Embodiment of this invention.

[0082] In the fifth embodiment, the auxiliary light source 220 is arranged on the hanging wire 110, but in the sixth embodiment, a support member 240 is provided on the lower end side of the transparent long cylindrical portion 180, and the auxiliary light source 220 for irradiating the vertically upward direction is arranged on the support member 240. Here, the spectral characteristics of each of the attracting light source 210 and the auxiliary light source 220 can be the same as those described in the fifth embodiment.

[0083] In the sixth embodiment, the transparent elongated cylindrical portion 180 is illuminated from the lower side by an auxiliary light source 220, so when the insect trap 100 of the sixth embodiment is combined with an embodiment in which an adhesive 270 is coated on the outer periphery of the transparent elongated cylindrical portion 180, or an embodiment in which an adhesive sheet 285 is arranged on the protective net 280, pests can be captured more effectively.

[0084] As described above, the insect trap involved in the present invention has a transparent long cylindrical portion that allows light to pass through the cylindrical portion vertically below the cylindrical portion. According to such an insect trap involved in the present invention, since the light from the attracting light source also reaches the area on the lower side through the transparent long cylindrical portion, the pests located in the area are attracted by the attracting light source and captured / expelled, thereby further improving the probability of expelling the pests and suppressing the damage of the pests to fruit trees, vegetables and crops.

[0085] Furthermore, according to the insect trap of the present invention, warm air can be supplied from the transparent long cylindrical portion to the vicinity of the roots of crops, the incidence of crop diseases can be reduced, and crops can be made strong near the roots, thereby increasing the yield of crops.

[0086] Industrial applicability

[0087] The present invention relates to an insect trap for attracting and expelling pests in order to reduce the pests from eating cultivated crops in a farm. In such an insect trap, there is the following problem: in the past, the light from the attracting light source could not reach the area on the lower side, and the probability that the pests in this area were attracted by the attracting light source and captured / expelled became very small. In addition, in crops with high height, there is the following problem: since cold air is retained near the roots, the incidence of diseases increases, and it is difficult to produce fruits near the roots, and the production volume decreases, but the conventional insect traps have not solved such problems.

[0088] The insect trap of the present invention has a transparent elongated cylindrical portion that allows light to pass through, located vertically below the cylindrical portion. According to such an insect trap of the present invention, since the light from the attracting light source also reaches the area on the lower side via the transparent elongated cylindrical portion, the pests located in the area are attracted by the attracting light source and captured / expelled, thereby further improving the probability of expelling the pests and suppressing the damage of the pests to fruit trees, vegetables, and crops. Furthermore, according to the insect trap of the present invention, warm air can be supplied from the transparent elongated cylindrical portion to the vicinity of the roots of the crops, the incidence of diseases of the crops can be reduced, and the crops can be hardened near the roots, and the production of the crops can be increased, and the industrial applicability is very large.
