Description

  The present invention relates to a pest control tool for preventing damage from pests that eat horticultural crops such as vegetables and fruit trees.

  In general, in horticultural crops such as vegetables and fruit trees, pests suck fruit juice at night or lay eggs on leaves, and then hatched larvae eat leaves, flowers and fruits. Typical examples of nocturnal pests that cause these damages are giant tobacco, hornbill, and weevil, which are particularly damaging to cabbage, broccoli, and tomatoes.

  As an anti-insect measure against the above-mentioned nocturnal pests, the method of illuminating the field at night has long been known, and it is famous to illuminate the field with a yellow fluorescent lamp.

  And the insect pest control system provided with the said yellow fluorescent lamp has already been proposed. This system includes an annular yellow fluorescent lamp, a reflector disposed on the back side of the yellow fluorescent lamp, and a leg that supports the reflector (see, for example, Patent Document 1).

Japanese Patent Laying-Open No. 2005-46018 (see paragraph 0023, FIG. 2)

"Cell engineering separate volume Plant cell engineering series 16 Light sensing of plants" published on October 1, 2001, see Shujunsha, Shozo Wada et al., P10-p55

  The yellow light from the yellow fluorescent lamp has a great influence on the flower bud formation of the plant, and may adversely affect the growth of the plant, and is difficult to employ (for example, see Non-Patent Document 1).

  In addition, since the pest control system of Patent Document 1 is a fluorescent lamp, not only a power source required to turn on the fluorescent lamp is required, but also this power source is connected to the fluorescent lamp via an electric wire. Connection work is required, and the installation work is troublesome and troublesome, and since the fluorescent lamp is a large ring, it cannot be placed in a narrow space between the ridge and the ridge, for example. For this reason, fluorescent lamps are arranged on the outer periphery of the plants in the greenhouse. In this case, the distance from the fluorescent lamp to the plants is farther as the plant located in the center of the greenhouse becomes larger. It was difficult to apply uniform light to all the plants.

  In view of the above-mentioned situation, the present invention intends to solve the problem that the growth of the plant is not adversely affected, the installation work can be performed quickly and the light for pest control is applied to all the target plants. It is an object of the present invention to provide a pest control device that can uniformly irradiate a worm.

  In order to solve the above-mentioned problems, the pest control device of the present invention irradiates green light by a solar battery that generates power using sunlight, a storage battery that stores the power generated by the solar battery, and power supply from the storage battery. A plurality of light emitting diodes, and a light irradiating portion is configured by arranging the light emitting diodes at least in the vertical direction on a vertically configured substrate, and the solar cell is disposed at an upper end of the light irradiating portion. It is characterized in that it is disposed and provided with means capable of self-supporting in the light irradiation part.

  By providing a plurality of light emitting diodes that emit green light as described above, the growth of the plant is not adversely affected, and it has a longer life and lower power consumption than a fluorescent lamp. In addition, since the light emitting diode is configured to emit light by the solar battery, connection work such as connecting the power source and the fluorescent lamp with an electric wire as in the fluorescent lamp becomes unnecessary, and the installation work can be performed easily and quickly. In addition, since the light irradiating unit is provided with a means capable of being self-supporting, a special construction or the like for making the light irradiating unit self-supporting is not required, and the installation work can be easily and quickly performed. Furthermore, since the light emitting diode is configured by arranging the light emitting diodes at least in the vertical direction on the vertically configured substrate, the light irradiating unit is formed even in a narrow space between the eaves and the eaves, for example. It becomes possible to irradiate all plants with light uniformly.

  Further, the pest control device of the present invention, the substrate is inserted into a transparent or translucent cylindrical member, the means is attached to the lower end of the cylindrical member, and is configured from a taper that tapers toward the lower end side. It may be.

  If the substrate is inserted into the transparent or translucent tubular member as described above, it is possible to prevent the tubular member from being exposed to rainwater or the like, particularly during outdoor use. In addition, the installation work of the pest control device is completed by inserting the tip attached to the lower end of the cylindrical member into the ground such as a field, and the pest control device can be collected by removing the tip from the ground when unnecessary.

  Moreover, the pest control tool of this invention may be equipped with the said solar cell so that angle adjustment is possible.

  If the solar cell is provided so that the angle can be freely adjusted as described above, the solar cell can be changed in an optimum direction with respect to sunlight by adjusting the angle of the solar cell.

  In the pest control device of the present invention, by using a plurality of light emitting diodes that emit green light, there is no adverse effect on the growth of the plant, and it is possible to eliminate the need for connection work with a power source. The light irradiation unit is configured by arranging light emitting diodes at least in the vertical direction on a vertically configured substrate so that the work can be performed quickly and can be reduced in size, so that it is between plants, i.e. Therefore, it is possible to provide a pest control tool that can uniformly irradiate light to all target plants. In addition, the use of a light emitting diode is advantageous in terms of running cost because it has a longer life and lower power consumption than a fluorescent lamp.

  FIG. 1 shows a pest control device 1 of the present invention for suppressing damage from nocturnal pests. As shown in the figure, the pest control device 1 is disposed in a narrow and narrow groove 3M located between two ridges 3 and 3 in which a plant 2 is planted.

  As shown in FIGS. 1 to 3, the pest control device 1 includes three solar cells 4 that generate power by sunlight and three storage batteries 5 that store electric power generated by the solar cells 4 (FIG. 3C). However, any number may be provided) and a plurality of light emitting diodes 6 that emit green light by supplying power from the storage battery 5. The light emitting diode 6 has no influence on the flower bud formation of the plant, has no possibility of adversely affecting the growth of the plant, and has a light wavelength of any wavelength in the range of 470 nm to 560 nm which is a green wavelength having a high pest control effect. It is something that emits.

  The storage battery 5 includes an electric double layer capacitor, a lead storage battery, a nickel cadmium battery, or the like. FIG. 3C shows three electric double layer capacitors. The storage battery 5 and the solar battery 4 are housed in a pair of upper and lower divided cases 7A and 7B. Of these divided cases 7A and 7B, at least the upper divided case 7A is formed of a case made of synthetic resin (or glass) such as transparent polycarbonate resin (PC) that can transmit light. For this reason, the sunlight can be reliably transmitted to the solar cell 4 through the upper split case 7A. The lower divided case 7B may also be composed of a synthetic resin (or glass) case such as a transparent polycarbonate resin (PC), like the upper divided case 7A. For example, it may be made of metal or wood. The pair of upper and lower divided cases 7A and 7B are detachably integrated through a plurality of screws 8 and 8.

  As shown in FIG. 2, the light-emitting diode 6 is provided on each of four substrates 9A, 9B, 9C, and 9D configured in a vertically long shape, and the four substrates 9A, 9B, 9C, and 9D are moved up and down. The light emitting diodes 6 and 6 adjacent to each other in the connected state in the connected state are arranged on the substrates 9A or 9B or 9C or 9D so as to have a constant interval. By arranging the light emitting diodes 6 and 6 at regular intervals, the illuminance can be made uniform in the irradiated portion when the light emitting diodes 6 and 6 emit light.

  The first substrate 9A located on the lowermost side is formed with a large number of holes (20 in the figure) at equal intervals in the longitudinal direction, and the 12th and 18th holes from the bottom of the many holes. A light emitting diode 6 is attached to the hole. Similarly to the first substrate 9A, the second substrate 9B located second from the bottom has a large number (20 in the figure) of holes formed at equal intervals, and the fourth and tenth 16th from the bottom. A light emitting diode 6 is attached to the hole. In addition, the third substrate 9C located third from the bottom is formed with a large number of holes (20 in the figure) at equal intervals, like the first substrate 9A, and the second, eighth and fourteenth holes from the bottom. A light emitting diode 6 is attached to the hole. Further, the fourth substrate 9D from the bottom is a spare substrate, and is configured to be approximately 1/3 times as long as the first substrate 9A, and a large number (seven in the figure) of holes are formed. It can be added and installed. By arranging the light emitting diodes 6 as described above, the number of holes between the light emitting diodes 6 and 6 adjacent in the vertical direction becomes five, and the light emitting diodes are arranged at equal intervals in the vertical direction. The reason why the mounting position of the first light emitting diode 6 on the first substrate 9A is the twelfth hole from the bottom is that the pest control tool 1 is disposed in the groove 3M lower than the rod 3, so that the first This is so considered that the light of the second light emitting diode 6 can illuminate the vicinity of the root of the plant 2. In each of the substrates 9A, 9B, 9C, 9D, by forming a large number of holes at equal intervals in the longitudinal direction, it becomes easy to change the pitch for attaching the light emitting diodes 6.

  Then, another vertical substrate 9 composed of four substrates 9A, 9B, 9C, and 9D to which the light emitting diode 6 similar to the above is attached is produced, and as shown in FIG. The pair of substrates 9 and 9 are inserted into a transparent cylindrical member 10 to constitute a light irradiation unit 11. The substrates 9 and 9 are arranged at intervals in the front-rear (or left-right) direction in a state where they are parallel to each other. Thereby, since the light from the light emitting diode 6 can be irradiated in the front-rear (or left-right) direction, the pest is effectively controlled against the plant located in the front-rear (or left-right) direction where the pest control device 1 is installed. Can be preferable. Further, the substrates 9 and 9 are arranged so that light from the light emitting diode 6 is emitted to the outside through the cylindrical member 10. The cylindrical member 10 is preferably a synthetic resin such as a transparent polycarbonate resin (PC), but can also be made of glass or the like. Further, the light diffusion effect can be enhanced by forming the cylindrical member 10 with a semi-transparent synthetic resin or the like. In some cases, the light transmitting diode 6 can be irradiated to the outside. If the hole is formed in the cylindrical member 10, the cylindrical member 10 can be made of a non-transparent material such as metal or wood (or synthetic resin).

  By arranging the split cases 7A and 7B in which the solar cells 4 and the like are accommodated at the upper end of the light irradiation unit 11 so as to overlap the light irradiation unit 11 in the vertical direction, as described above, The pest control device 1 can be disposed without being obstructed by the narrow groove 3M.

The light irradiation unit 11 is provided with means 12 that can stand on its own.
As shown in FIG. 2, the self-supporting means 12 is attached to the lower end of the cylindrical member 10, and is configured with a taper that tapers toward the lower end side. The tapered portion 12 is made of acrylonitrile / butadiene / styrene copolymer synthetic resin (ABS) and the like, and extends upward from the top end of the conical tip portion 12A and the tip end portion 12A. And an extended portion 12B. Therefore, the insect pest control tool 1 can be quickly made independent by holding the cylindrical member 10 and pushing the tapered portion 12 into the groove 3M (see FIG. 1).

Moreover, the solar cell 4 is configured to be adjustable in angle so that sunlight can be efficiently taken into the solar cell 4, and the configuration will be described.
As shown in FIGS. 3B, 3C, and 3D, a bracket that extends downward to the center of the lower end of the lower divided case 7B in which the upper and lower divided cases 7A and 7B accommodate the solar cell 4 and the like. A receiving member 13 for receiving the bracket portion 7C is externally fitted to the upper end of the cylindrical member 10 and fixed by a bolt 14 so as not to come off.

  The receiving member 13 is made of a synthetic resin such as polycarbonate resin (PC), and has a cylindrical cross-sectional shape that is externally fitted to the upper end of the cylindrical member 10 and a top plate portion 13a of the cap portion 13A. A pair of left and right protruding pieces 13B, 13B extending upward is provided. And the through-holes 13b and 13b which can penetrate the volt | bolt 14 are formed in protrusion piece 13B, 13B, and also the bracket part 7C inserted in the clearance gap formed between the protrusion pieces 13B and 13B, A through hole 7c that can penetrate the bolt 14 is provided. Therefore, after inserting the bracket part 7C between the projecting pieces 13B and 13B so that the through holes 13b and 13b of the projecting pieces 13B and 13B and the through hole 7c of the bracket part 7C match, the through holes 13b and 7c, The bracket portion 7C can be fixed between the protruding pieces 13B and 13B by screwing the nut 15 into the tip of the bolt 14 protruding through the bolt 14 through 13b. Then, the angle of the solar cell 4 can be adjusted by rotating the bracket portion 7C around the axis X of the bolt 14 by loosening the bolt 14. When the angle adjustment is completed, the solar cell 4 can be fixed at the angular position by fastening the bolt 14 to the nut 15 again.

  The pest control device 1 configured as described above receives sunlight in the daytime and the solar cell 4 generates electric power, and the generated electric power is stored in the storage battery 5. By outputting the electric power stored during the daytime to the light emitting diode 6 at night, the light emitting diode 5 irradiates the plant 2 with green light, and in particular, the behavior of nocturnal pests can be suppressed.

Table 1 shows the experimental results regarding the influence of the light irradiation of the light emitting diode 6 on the mating of, for example, tobacco. The experiment was carried out by separating adult adults of the tobacco tobacco into a zone (treatment zone) where the light emitting diode 6 was irradiated with green light having a wavelength of 525 nm and a zone where no illumination was performed (non-illuminated zone) (treatment zone). . An area (treatment area) is a greenhouse with a height of 35 m ² and a height of 2.5 m.

  As shown in Table 1, the mating female ratio of the tobacco tobacco was 16.7% in the treatment group irradiated with green light, and 100% in the treatment group without illumination. From this result, it was possible to inhibit the activity of Tobacco spp. By emitting a green color.

  Moreover, in Table 2, the treatment ratio which continually illuminates green light with a wavelength of 525 nm and the treatment area in which the illumination time is reduced by 80%, are the representative female pests of the mosquito moth and the moth, which is a typical pest of vegetables. Experiments were carried out in three treatment areas, which were the non-illuminated treatment areas.

  In Table 2, the mating female ratio of Spodoptera litura was able to be kept low as in the case of continuous illumination even when the illumination time was reduced by 80%. Also, with Yotoga, an effective mating inhibition rate was obtained even when it was reduced by 80% compared to the case without illumination.

  In addition, this invention is not limited to the said embodiment, A various change is possible in the range which does not deviate from the summary of this invention.

  In the above-described embodiment, the pest control device 1 is configured to be self-supporting by pushing the taper 12 into the groove 3M. However, instead of the taper 12, a plurality of legs that can be grounded and stand on the groove 3M are provided. You may let them.

  Moreover, in the said embodiment, although the eight light emitting diodes 6 were provided in the pest control tool 1, the number of the light emitting diodes 6 can be changed freely. Moreover, the structure which makes all the light emitting diode 6 with which the insect pest control tool 1 is equipped continuously light or blinks, or makes some light emitting diodes 6 light continuously or blinks may be sufficient.
