  The insect trapping system according to the present invention is an insect trapping system configured by installing an insect trapping device at a height position within 80 cm from the ceiling.

[Insect catching device]
The insect trapping device is a so-called light trap type insect trapping device having a light source that emits light that attracts harmful insects to the stored product and a capturing unit that captures the insects attracted by the light from the light source.

  The light source of the insect trapping device is not particularly limited as long as it emits light (ultraviolet light) having an insecticidal effect, and a light source having a wavelength of 340 nm to 400 nm as a main wavelength is intended. As such a light source, for example, a fluorescent light for trapping such as black light (BL) or black light blue (BLB) and a conventionally known insect light source such as UV-LED can be used.

  It is intended that the catching part of the insect trapping device is not only formed by means for catching pests, but can also comprise means for killing pests. There is no limitation on the mode of the capturing unit, and conventionally known modes such as an adhesive type, suction type, electric shock type, poisoning type, thermal insecticidal type, a method of capturing in water, and a method of capturing in foam can be used. However, since the insect trapping device is installed at a high place (within 80 cm from the ceiling) in this insect trapping system, it is preferably an adhesive or suction type from the viewpoint of safety.

  In the insect trapping system according to the present invention, the insect trapping apparatus is installed indoors and is installed at a height within 80 cm from the indoor ceiling. The installation position of the insect trapping device may be a height position within 80 cm from the ceiling, for example, may be a height position of 50 cm from the ceiling, and particularly preferably a position in contact with the ceiling (a height position of 0 cm from the ceiling). It is. By installing the insect trapping device at a height within 80 cm from the ceiling, it is possible to improve the insect trapping rate.

  In addition, the distance from the wall which installs an insect capturing apparatus is not restrict | limited in particular, For example, it can install in the position within 2 m from a wall. When the distance from the wall to the installation position is within 2 m, excellent insect trapping efficiency can be realized in this insect trapping system. In addition, even when the installation position of the insect trapping device is more than 2m from the wall, for example, 3m away from the wall, the trapping efficiency is about 70% compared to the case where the insect trapping device is installed directly on the wall. it can. Therefore, the case where the insect trapping device is installed in a place exceeding 2 m from the wall is also included in the category of the present invention.

  There is no limitation on the number of insect trapping devices used in a certain room, and it may be determined as appropriate according to the size or volume of the room to which the insect trapping system of the present invention is applied. Further, when the insect trapping devices are installed at a plurality of locations in a certain room, the heights of the respective installation positions may be the same or different. When the height of each installation position differs, at least any one should just be a height position within 80 cm from a ceiling. Further, the trapping modes of a plurality of trapping devices may be the same or different.

  Furthermore, the insect trapping system according to the present invention only needs to include a light trap type insect trapping device, and does not exclude the combined use of other types of insect trapping devices. For example, a so-called pheromone trap type trapping device that attracts and captures pests with a pheromone having an insecticidal effect may be used together with a light trap type trapping device.

[Storage]
As used herein, a store is intended to be a pest target. Examples of stored products include plants, processed plant products (including dried plants), food products, dried animal and plant specimens, animal feed, and oil meal. More specifically, processed cereals such as wheat flour and corn flour, spices, and dried products such as herbal medicines, dried fruits and dried leaf tobacco. In order to capture pests on these stored products, it is also included in the scope of the present invention to use the present insect capturing system indoors where these stored products are manufactured.

〔pest〕
The insect pests to be captured by the insect trapping system according to the present invention are not particularly limited as long as they are harmful to stored products. Rice beetle, Guinea beetle, Kakunehiratamashi, Tobacco giant beetle, Sawtooth worms, Red-footed beetle, Clear-bellied beetle, Nisemaru leopard beetle, Green-bellied beetle, Tobacco beetle, Jin-sangabi-shinga Sinkui, Chiesae, Noshimamearameiga, Sudamadarameiga, Suikokonadameaga, Chamadarameiga, Tsurugiga and Bakuga. Among these pests, beetles are preferable, and among the beetles, insects belonging to the order of the beetle family such as tobacco beetle and dinosa beetle are more preferable, and tobacco beetle which is a pest of dry leaf tobacco is particularly preferable. If it is a tobacco beetle, the insect trapping effect in the system which concerns on this invention improves more.

〔illumination〕
Since the insect trapping system according to the present invention is implemented indoors, the insect trapping system may further include illumination for illuminating the interior. The illumination is preferably installed at a position lower than the insect trapping device, and more preferably 1 m or more away from the ceiling. By setting the installation position of the illumination to the above position, the number of insects attracted by the illumination can be reduced, and as a result, the insect capture rate by the insect trapping device can be improved.

  For lighting, a general commercially available lighting fixture such as a fluorescent lamp, a mercury lamp, a metal halide lamp, and a white LED can be used. In order to improve the insect trapping rate in the insect trapping apparatus, it is preferable to reduce the number of harmful insects attracted by illumination. From such a viewpoint, it is preferable that the light emitted from the illumination has reduced ultraviolet light or does not contain ultraviolet light. Insects, including pests, are attracted to ultraviolet light to better recognize ultraviolet light. Therefore, by using illumination that emits light that is reduced or does not contain ultraviolet light, the pests attracted by the illumination are further reduced, thereby improving the catching rate in the trapping device Can do.

  The method for reducing the ultraviolet light in the light emitted from the illumination or not including the ultraviolet light is not particularly limited. For example, a method of applying an ultraviolet cut film or an ultraviolet cut sleeve that reduces, suppresses or blocks ultraviolet emission by using an ultraviolet reflector or an ultraviolet absorber to conventional illumination, or an LED lamp that emits only visible light. The method to use etc. are mentioned.

  It is more preferable to cut light with a wavelength of 410 nm or less from the aspect of color rendering properties as well as reduction of worms by illumination. For example, by using a UV cut sleeve (trade name: UV Gurad) manufactured by Fuji Film, light with a wavelength of 410 nm or less can be cut in a conventional fluorescent lamp.

  Examples will be shown below, and the embodiments of the present invention will be described in more detail. Of course, the present invention is not limited to the following examples, and it goes without saying that various aspects are possible in detail.

In one test, all four units are installed at the same height position. Test insects were released at 17:00 from 8 points apart from each other on the floor of the warehouse (50 per point). Only the light trap light source is turned on under dark conditions, and the number of insects captured in the light trap is measured 16 hours later (9 am the next morning). The test under the same conditions was repeated three times. In addition, the repetition test performed alternately the case where it installed in the distance of 0.0 m from the ceiling, and the case where it installed in the distance of 0.8 m.

  The results are shown in FIG. FIG. 2 shows the average number of insects (± SE) from three tests.

  As shown in FIG. 2, when the light trap was installed at a height of 0.0 m from the ceiling, the most test insects were captured. In addition, even when the light trap is installed at a height of 0.8 m from the ceiling, the number of test insects is about 70% compared to the case where it is installed at a height of 0.0 m from the ceiling. Can be captured and shown to be sufficiently effective.

[Example 3: Insect inhibition using UV cut illumination]
A test was conducted on the effect of preventing the insect attracting light by the presence or absence of the UV cut of the lighting in the test room where the lighting was turned on. The test conditions are as follows.
-Implementation place, test insects and light trap used: Same conditions as in Example 1.
-Light trap installation position: Installed on a wall at a height of 0.0m from the ceiling.
-Light used: 3 fluorescent lamps for appraisal of leaf tobacco (Toshiba Lighting & Technology: 40W type).
-UV cut sleeve: 3 pieces of UV Guard (product name, manufactured by Fuji Film: 40W type).
-Test method: Fig. 3 shows an outline of the system in this test method. One light trap 2 is installed on the ceiling. Three fluorescent lamps (40 W) for leaf tobacco appraisal (hereinafter simply referred to as appraisal fluorescent lamps) were hung as illumination 3 1 m below the center of the test room ceiling. In order to capture the test insects 4 attracted to the fluorescent lamp for identification of the illumination 3, a slide board 5 made of polyvinyl chloride (height: 1m, width: 1.8m) is suspended vertically under the illumination 3 and slides down. An adhesive plate 6 (0.6 × 1.8 m) was placed horizontally on the desk 7 (height from the floor: 1 m) directly below the plate 5. Test insects are released from four points on the floor (positions 2m forward and 2m deep in the depth direction from the center of the room, and 1.5m left and 1.5m on the right side of the room along the front). (50 per spot). The number of test insects (number of insects) captured on the adhesive plate 6 was measured 3 hours after release. The indoor lights are only the lights of the lighting 3 and the light trap 2. For each of the following test phrases, the test under the same conditions was repeated three times.
-Test section: (i) Lights without UV cut sleeve attached to appraisal fluorescent lamp (light trap is not lighted), (ii) Lights with UV cut sleeve attached to appraisal fluorescent light (light trap is not lighted) Lighting), (iii) The light trap is turned on under the conditions of (i), and the light trap is turned on under the conditions of (iv) (ii).

  The results are shown in FIG. FIG. 4 shows the average number of trapped insects (± SE) of three tests.

  As shown in FIG. 4, when the UV cut sleeve is attached to the fluorescent lamp for examination (test group ii), the number of test insects attracted by illumination is 60% compared to the control (test group i). It was reduced to a degree. Similarly, when the light trap is turned on without attaching the UV cut sleeve to the fluorescent lamp for examination (test section iii), the number of test insects attracted by the illumination is 50% compared to the control. It was reduced to a degree. Furthermore, when a UV cut sleeve is attached to the fluorescent lamp for identification and the light trap is turned on (test section iv), the number of test insects attracted by illumination is about 30% compared to the control. There was a decrease compared to the single use of each of the UV cut sleeve and the light trap.

  From the above results, the UV-cut sleeve is attached to the indoor lighting installed 1m below the ceiling, and the use of a light trap inhibits the attraction of tobacco beetles to the indoor lighting (appraisal fluorescent lamp). It was confirmed. In other words, it was confirmed that the insect trapping inhibition by indoor lighting was reduced in the capture of pests by the light trap.

[Example 4: Distance from wall of light trap installation position]
In order to confirm the influence of the distance from the wall with respect to the light trap installation position, the insect trapping test was carried out for the released tobacco beetle by changing the distance from the wall at the light trap installation position. The test conditions are as follows.
-Location and light trap used: Same as Example 1.
-Test insect: Same as Example 1 except that the number of test specimens was increased to 200.
-Light trap installation position: All the distance from the ceiling is 0.0 m (directly attached to the ceiling), and the distance from the wall is 0.0 m, 0.5 m, 0.75 m, 1.0 m, or 2.0 m. Installed as follows.
-Test method: One light trap is installed at any of the above positions. The test insects were released at 17:00 from the floor at a point about 3.0m away from the wall. Only the light trap light source is turned on under dark conditions, and the number of insects captured in the light trap is measured 16 hours later (9 am the next morning). The test under the same conditions was repeated three times.

  The results are shown in FIG. FIG. 4 shows the average number of trapped insects (± SE) of three tests.

  As shown in FIG. 4, even when the light trap was installed away from the wall, no difference was found in the average number of insect traps (p <0.05, (Multiple comparison by Tukey-HSD method). From the above results, it was shown that high trapping efficiency can be obtained at any position as long as the light trap is installed at least at a distance of 2 m from the wall. Note that, in a warehouse wider than the place where the test in the present example was performed, the same test was performed with the distance from the wall of the light trap installation position set to 3.0 m. As a result, the distance from the wall was 0.0 m. Compared to the case, about 70% of the test insects could be captured. That is, even if the distance from the wall of the light trap installation position is 3.0 m or more, it was shown that the effect is sufficiently effective.
