[0007] The above-described whitefly attractant device makes it easy to efficiently capture large numbers of whiteflies. [Brief explanation of the drawing]

[0008] [Figure 1] Figure 1 is a schematic perspective view showing the external appearance of the whitefly attractant device in Embodiment 1. [Figure 2] Figure 2 is a schematic cross-sectional view showing a part of the whitefly attractant device shown in Figure 1. [Modes for carrying out the invention]

[0009] [Summary of the Embodiment] The whitefly attractant device of this disclosure is a whitefly attractant device for attracting and capturing whiteflies, and comprises a hollow cylindrical pipe section, a base section attached to one end of the pipe section in the longitudinal direction and covering the opening on the one end side, a suction pump attached to the other end of the pipe section in the longitudinal direction and sucking air from inside the pipe section, and a rod-shaped light that extends in the longitudinal direction of the pipe section, is positioned inside the pipe section at a distance from the inner circumferential surface of the pipe section and emits yellow light. The pipe section is provided with a long slit in the longitudinal direction of the pipe section. The width of the slit is 2 mm or more and 20 mm or less. The air velocity of the air sucked in by the suction pump in the region where the slit is located is 2 m / sec or more and 5 m / sec or less.

[0010] According to the whitefly attractant device described herein, a light emitting yellow light is installed inside a hollow cylindrical pipe section with slits. By illuminating the light, whiteflies can be attracted to the space inside the pipe section through the slits. In this case, since the width of the slits is 2 mm or more, the risk of whiteflies getting caught in the pipe section is reduced, allowing them to pass through the slits smoothly. Furthermore, since the air inside the space inside the pipe section is sucked out by a suction pump, the whiteflies that have passed through the slits can be easily collected. In this case, the air velocity sucked out by the suction pump in the area where the slits are located is between 2 m / s and 5 m / s. This allows for more reliable capture and moderate killing of whiteflies that have passed through the slits while suppressing the power consumption of the suction pump. Here, since the width of the slits is 20 mm or less, the suction power of the suction pump can be kept within the above air velocity range without excessively increasing it. Furthermore, with this mechanism, the operator of the whitefly attractant device only needs to turn on the light when attracting and capturing the whiteflies, thus improving work efficiency and enabling efficient capture of whiteflies. Therefore, the above-described whitefly attractant device makes it easy to efficiently capture large quantities of whiteflies.

[0011] In the above-described whitefly attractant device, the suction force of the suction pump may be between 1000 Pa and 5000 Pa. With such a configuration, it is easier to keep the wind speed within the range described above. Therefore, it is possible to more reliably keep the wind speed within the range described above.

[0012] In the above-described whitefly attractant device, the light may include an LED light. With such a configuration, it becomes easier to reduce power consumption, extend the lifespan, and improve maintainability, resulting in greater efficiency.

[0013] In the above-described whitefly attractant device, the air velocity of the air sucked in by the suction pump may be 3 m / second or higher. This makes it easier to reliably kill whiteflies that are caught in the sucked air. Therefore, the collected whiteflies can be dried to suppress decay, making it easier to maintain a more hygienic environment.

[0014] In the above-described whitefly attractant device, the inner surface of the pipe section may be cylindrical. The light may be a solid cylinder. By doing so, it is possible to suppress air stagnation and turbulence inside and outside the pipe section. Therefore, whiteflies can be attracted and collected more efficiently.

[0015] The above-described whitefly attractant may further include a collection lid attached to the opposite side of the suction pump from the pipe section to store the collected whiteflies. This allows the collected whiteflies to be stored and collected in the collection lid, enabling efficient collection of the collected whiteflies. Therefore, it becomes easier to improve maintainability.

[0016] In the above-mentioned small brown planthopper attracting device, a plurality of slits may be provided at intervals in the longitudinal direction of the pipe portion. As the length of the slit increases, the amount of small brown planthoppers collected can be increased, but the strength of the pipe portion may decrease. However, by doing so, the risk of a decrease in the strength of the pipe portion can be reduced, and the risk of damage to the device itself can be reduced.

[0017] [Specific Example of Embodiment] Next, an example of a specific embodiment of the small brown planthopper attracting device of the present disclosure will be described while referring to the drawings. In the following drawings, the same or corresponding parts are denoted by the same reference numerals and their description will not be repeated.

[0018] (Embodiment 1) The configuration of the small brown planthopper attracting device in Embodiment 1 of the present disclosure will be described. FIG. 1 is a schematic perspective view showing the appearance of the small brown planthopper attracting device in Embodiment 1. FIG. 2 is a cross-sectional view schematically showing a part of the small brown planthopper attracting device shown in FIG. 1. FIG. 2 is a cross-sectional view when cut along the cross-section indicated by arrow II-II in FIG. 1.

[0019] Referring to FIGS. 1 and 2, the small brown planthopper attracting device 10 in Embodiment 1 attracts and collects small brown planthoppers. Such a small brown planthopper attracting device 10 is arranged, for example, at a corner inside a vinyl house for cultivating melons and tomatoes. Of course, it can also be installed near the cultivated land of other crops that need to attract and collect small brown planthoppers.

[0020] The thrips attracting device 10 includes a pipe portion 11, a pedestal portion 12, a suction pump 13, a light 14, and a collection lid 15. The pipe portion 11 is in a hollow cylindrical shape. That is, a space 21 is provided inside the pipe portion 11. In the present embodiment, the pipe portion 11 is in a hollow cylindrical shape. That is, the inner peripheral surface 22 and the outer peripheral surface 23 of the pipe portion 11 are circumferential surfaces. As the length of the pipe portion 11 in the longitudinal direction, for example, those having a length of 600 mm or more and 1200 mm or less are preferably used. As the inner diameter of the pipe portion 11, those having an inner diameter of 70 mm or more and 150 mm or less are preferably used, and as the thickness of the pipe portion 11, those having a thickness of 3 mm or more and 20 mm or less are preferably used. As the material of the pipe portion 11, from the viewpoints of portability and low cost, for example, those made of resin, specifically, those made of vinyl chloride are used.

[0021] The pedestal portion 12 is in a flat plate shape. In the present embodiment, the pedestal portion 12 is rectangular when viewed in the thickness direction (the longitudinal direction of the pipe portion 11). The pedestal portion 12 is attached to one end side in the longitudinal direction of the pipe portion 11 and covers the opening on one end side of the pipe portion 11. The thrips attracting device 10 can be made to stand on the ground by placing the pedestal portion 12 on the ground.

[0022] The suction pump 13 is attached to the other end side in the longitudinal direction of the pipe portion 11. In the present embodiment, the suction pump 13 is attached to the upper part of the pipe portion 11. Specifically, the suction pump 13 is directly connected to the other end of the pipe portion 11. In the present embodiment, the opening on the other end side in the longitudinal direction of the pipe portion 11 is covered by the suction pump 13. The suction pump 13 sucks the air in the space 21 inside the pipe portion 11 by supplying electric power. As the suction pump 13, for example, those having a suction force of 1000 Pa or more and 5000 Pa or less are adopted in consideration of the wind speed described later.

[0023] Light 14 is rod-shaped. Light 14 extends in the longitudinal direction of the pipe section 11. Light 14 emits yellow light, that is, light with a wavelength of 550 nm to 590 nm. In this embodiment, light 14 is an LED light. Light 14 is placed inside the pipe section 11, that is, in the space 21. Light 14 is placed at a distance from the inner circumferential surface 22 of the pipe section 11.

[0024] The collection cover 15 is attached to the side of the suction pump 13 opposite to the pipe section 11. The collection cover 15 is mesh-like and flexible. The size of the mesh of the collection cover 15 is such that the collected whiteflies cannot pass through. The whiteflies collected by the suction pump 13 are stored in the collection cover 15.

[0025] Here, the pipe section 11 is provided with slits 24 and 25 that are long in the longitudinal direction of the pipe section 11. Multiple slits 24 and 25 are provided at intervals in the longitudinal direction of the pipe section 11; in this embodiment, two slits are provided. Each of the slits 24 and 25 penetrates the pipe section 11 in the radial direction. The slits 24 and 25 open straight in the longitudinal direction. In this embodiment, the slits 24 and 25 are arranged side by side in the longitudinal direction. The width of the slits 24 and 25, indicated by arrow T1 in Figures 1 and 2, is 2 mm or more and 20 mm or less. Specifically, for example, a width of 2.5 mm is preferably selected for the slits 24 and 25. Also, for example, the longitudinal lengths D1 and D2 of the slits 24 and 25 are preferably selected to be 50 mm or more and 130 mm or less.

[0026] Furthermore, the air velocity drawn in by the suction pump 13 in the region where the slits 24 and 25 are located is between 2 m / s and 5 m / s. More specifically, the air velocity drawn in by the suction pump 13 is 3 m / s or more.

[0027] To explain the operation of this whitefly attractant device 10, the operator turns on the light 14. The light 14 then emits a yellow light. After that, the suction pump 13 is activated to suck in the air in the space 21. After a predetermined time has elapsed, the whiteflies, attracted by the yellow light, fly through the slits 24 and 25 and enter the space 21. The suction pump 13 sucks in the air in the space 21 at a wind speed of 2 m / s to 5 m / s, so the whiteflies are collected on the side of the suction pump 13 and finally stored in the collection lid 15.

[0028] With this type of whitefly attractant 10, a light 14 emitting yellow light is installed inside a hollow cylindrical pipe section 11 with slits 24 and 25. By turning on the light 14, whiteflies can be attracted through the slits 24 and 25 into the space 21 inside the pipe section 11. In this case, since the width of the slits 24 and 25 is 2 mm or more, the risk of whiteflies getting caught in the pipe section 11 is reduced, and they can pass through the slits 24 and 25 smoothly. Furthermore, since the air in the space 21 inside the pipe section 11 is sucked in by the suction pump 13, the whiteflies that have passed through the slits 24 and 25 can be easily collected. In this case, the air velocity sucked in by the suction pump 13 in the area where the slits 24 and 25 are located is between 2 m / s and 5 m / s, so the power consumption of the suction pump 13 can be suppressed while more reliably capturing and moderately killing the whiteflies that have passed through the slits 24 and 25. Here, since the width of the slits 24 and 25 is 20 mm or less, the suction power of the suction pump 13 can be kept within the above range of wind speed without excessively increasing it. Furthermore, with this mechanism, the operator of the whitefly attracting device 10 only needs to turn on the light 14 when attracting and collecting whiteflies, thus improving work efficiency and enabling efficient collection of whiteflies. In summary, the above whitefly attracting device 10 makes it easy to efficiently collect a large number of whiteflies.

[0029] According to this embodiment, the suction force of the suction pump 13 is between 1000 Pa and 5000 Pa. With this configuration, it is easier to keep the wind speed within the above-mentioned range. Therefore, it is possible to more reliably keep the wind speed within the above-mentioned range.

[0030] In this embodiment, the light 14 is an LED light. With this configuration, it becomes easier to reduce power consumption, extend lifespan, and improve maintainability, resulting in greater efficiency.

[0031] In this embodiment, the air velocity of the air sucked in by the suction pump 13 is 3 m / second or more. Therefore, it is easy to reliably kill whiteflies that are caught in the sucked air. Consequently, the collected whiteflies can be dried to suppress decay, making it easier to maintain a more hygienic environment.

[0032] In this embodiment, the inner circumferential surface 22 of the pipe section 11 is cylindrical. The light 14 is a solid cylinder. Therefore, it is possible to suppress air stagnation and turbulence inside and outside the pipe section 11. Consequently, whiteflies can be attracted and captured more efficiently.

[0033] In this embodiment, the whitefly attractant 10 is attached to the opposite side of the pipe section 11 of the suction pump 13 and includes a collection lid 15 for storing the collected whiteflies. Therefore, the collected whiteflies can be stored and collected in the collection lid 15, allowing for efficient collection of the collected whiteflies. Consequently, it becomes easier to improve maintainability.

[0034] In this embodiment, multiple slits 24 and 25 are provided at intervals along the longitudinal direction of the pipe section 11. While increasing the length of the slits 24 and 25 allows for greater whitefly collection, it may reduce the strength of the pipe section 11. However, this approach reduces the risk of reduced strength in the pipe section 11 and thus reduces the risk of damage to the device itself.

[0035] (Other embodiments) In the above embodiment, the suction pump 13 is directly connected to the pipe section 11. However, this is not the only option. For example, a tubular hose may be attached to the other end of the pipe section 11, and the suction pump 13 may be attached to the end of the hose to draw air from the space 21.

[0036] Furthermore, in the above embodiment, the slits 24 and 25 are arranged side by side in the longitudinal direction, but the invention is not limited to this, and the slits 24 and 25 may be arranged at different positions in the circumferential direction. Alternatively, the slits 24 and 25 may be arranged side by side in the circumferential direction. There may be only one slit 24 or 25. Also, in the above embodiment, the slits 24 and 25 are assumed to open straight in the longitudinal direction, but the invention is not limited to this, and the slits 24 and 25 may open at an inclination with respect to the longitudinal direction, or the slits 24 and 25 may meander.

[0037] The embodiments disclosed herein should be understood to be illustrative in all respects and not restrictive in any way. The scope of the present invention is defined by the claims and is intended to include all modifications in the sense and scope equivalent to the claims. [Explanation of symbols]
