    专利说明:

    The invention relates to an arrangement for attracting insects having the features of the introductory part of claim 1 (WO 2014/107753 A). For attracting and in particular catching and possibly killing insects various devices and traps ("insect traps") are known. Examples of known traps include slit traps, bark beetle slit traps, dry or wet traps with baffles, slotted hopper traps, trap lions, sticky traps with three-sided, sticky prism, trap traps and insect traps with pyramidal mesh.
    In order to enhance attracting insects, known traps frequently become messengers (semiochemicals, e.g.
    Pheromones).
    The problem is that messengers alone are not enough to attract insects with known traps sufficiently effective.
    It has already been proposed to improve the insect attracting effect using electromagnetic radiation emitting sources.
    WO 2006/121346 A describes an insect trap with "Anlockeinrichtung" having an arranged inside the trap IR source. So insects are to be lured into an area of the trap, from which they can not come out again. The IR source may be a heater or an LED. Preferably, several IR sources are provided which emit variable IR radiation. The IR source can be combined with a light source, in particular for UV light or visible light.
    From the generic WO 2014/107753 A an arrangement for attracting insects is known. The known arrangement comprises an insect trap equipped with a messenger (semiochemical, such as pheromones). The insect trap is associated with at least one source of insect-attracting, electromagnetic radiation, in particular infrared radiation, thermal radiation and / or ultraviolet radiation in such a way that the radiation directed to the insect trap is reflected by reflection surfaces. As a result, insects are increasingly attracted and can be caught.
    The problem with the known lure devices is that they require electrical energy for the operation of the radiation sources.
    The invention has for its object to provide an arrangement of the type mentioned, with the attraction of insects and subsequently, for example, the catching and / or killing thereof is improved in traps.
    This object is achieved according to the invention with an arrangement having the features of claim 1.
    Preferred and advantageous embodiments of the invention are the subject of the dependent claims.
    With the invention, the properties (parameters) of generic devices, whether it is an insect trap or a device with a pyramidal network, so changed that insects are attracted reinforced and safe. An essential feature of the arrangement according to the invention is that the device or the insect trap has at least one reflecting area (reflecting surface) which reflects light, in particular sunlight, in the same way as the host, which is attacked by the insect as a pest. For example, the host is a tree, in which case the reflection spectrum of the at least one area (reflecting surface) of the arrangement according to the invention is chosen such that it corresponds to the reflection spectrum of the host, e.g. of the tree that is attacked by the insect comes as close as possible.
    If, according to one possible embodiment, the arrangement designed according to the invention is combined with a pheromone (semiochemical) specific for the insect to be lured and / or killed, a particularly good effect and effectiveness of the arrangement according to the invention are obtained.
    Although the inventive arrangement without its own light source shows a high efficiency in attracting insects, the effectiveness of a light source associated with the arrangement can be further increased. The light source may be a light source that emits light that substantially matches sunlight, or that emits light at a wavelength that exhibits an insect-attracting effect per se, as known from WO 2014/107753 A, for example.
    In the invention, the arrangement may have in its entirety a surface which has the reflection spectrum selected according to the invention (reflection pattern), ie is insect-specific reflective, or there are selected areas of the arrangement as insect-specific reflection surfaces, which has the advantage that for the rest of the construction the arrangement conventional materials can be used.
    Unlike the known arrangements of the aforementioned type, a source emitting electromagnetic radiation in the arrangement according to the invention is no longer absolutely necessary, since the arrangement according to the invention for attracting insects is effective even without radiation sources.
    In one embodiment, the invention allows insects (such as bark beetles) to be attracted to messenger substances (semiochemicals or pheromones, allelochemicals, kairomones, allomones) which have an attractant effect on the insects (as described above), supplemented by at least one region of the arrangement. which significantly increases the attraction to the insects (and thus depending on the application, the catch in the trap system or the effect of attract-and-kill) by its special, namely insect-specific reflection spectrum.
    The invention can be used in all combinations with other systems that attract insects.
    In one embodiment, this is a symbiotic system, in which the interaction between messenger substance (semiochemical) and the reflection surface according to the invention significantly increases the attracting effect.
    The arrangement according to the invention may comprise a source which emits electromagnetic radiation (light). In this case, it is preferred that the radiation is directed to the region of the arrangement which is designed to be reflective in an insect-relevant spectrum.
    Further details, features and advantages of the invention will become apparent from the following description of preferred Ausführüngsbeispiele, in which reference is made to the schematic drawings. It shows:

    In all of the embodiments of an inventive arrangement described below, insect traps or insect attracting and killing systems preferably provide at least one messenger (semiochemical, such as an insect-specific pheromone) for attracting the insects. Furthermore, in all embodiments, an arrangement according to the invention may be associated with electromagnetic radiation (e.g., light) emitting sources. However, such sources are not mandatory in the arrangement according to the invention.
    FIG. 1 shows a known slot trap 1, in particular a slot trap for catching bark beetles. The slot trap 1 has a base body 2 with slots 3, pass through the bark beetle in the interior of the slot trap 1, and at the bottom of a removable container 4, fall into the bark beetle and collected there. In detail, the slot trap 1 consists of the actual case, which is a box-shaped component with slots 3 in the side walls 5 and with the side walls 5 obliquely upwardly pointing tabs 6. At the lower end of the slot trap 1, a funnel is inserted into grooves, under which the container 4 is arranged, which can also be inserted into the grooves.
    The main body 2 of the slot trap 1 is formed of a material or at least coated with such a material having a reflection spectrum (reflection pattern), which is chosen so that the reflection of light, in particular of sunlight, an attracting effect on insects.
    It is not necessary that the entire outer surface of the slot trap 1 is formed insect-specific reflective, but it is sufficient if individual areas are equipped with reflective surfaces that reflect sunlight so that insects are attracted.
    Fig. 9 is a diagram showing reflection patterns of tree bark, e.g. Bark samples of spruce, reproduced with different structure and color (thin-caked, coarse-grained). It can be seen that the curves are very similar for fine-bumped sample, for large-bumped sample dark and for coarse-barked sample. This shows that not only the surface structure but also the color has an influence on the course of the curves.
    FIG. 10 shows reflectance spectra of samples from trees of different vitality classes, namely bark samples from a completely healthy tree, one freshly attacked by bark beetles and one already dead. It can be seen that the curve 1 "healthy tree", the curve 2 "freshly attacked tree" and the curve 3 "dead tree" are almost identical.
    Shown in Figs. 11 and 12 are reflectance spectra of materials used in accordance with the present invention in insect attracting arrangements, with the outward facing ones
    Parts of the arrangement either consist entirely of this material or have reflective surfaces, which are made of these materials.
    Fig. 11 shows three curves, "platelet light", "platelet dark" and "platelet middle", and Figure 12 is a plot of the reflectance spectrum of "FIB bright" and "FIB dark".
    It can be seen that the reflection spectra of FIG. 11 and the reflection spectrum of the FIB light sample of FIG. 12 are very similar to the bark surface reflection spectrum as shown in FIGS. 9 and 10. FIG.
    In particular, a reflection maximum is in the range of about 50 nm and another in the range of about 1300 nm.
    Experiments with an insect trap 1 according to Fig. 9, which are partially, e.g. in the area of areas 9, coated with the material FIB-bright, showed increased attracting effect on bark beetle (Ips typographus, Pityogenes chalcographus).
    This means that with an inventively constructed arrangement, for example a slot trap 1 according to FIG. 9, the outer surfaces of which at least in regions have a reflection spectrum such as the substance FIB-bright, the attracting of bark beetles is particularly successful.
    The examined substances had the following composition: Fia. 9 fine-bark specimen bark of a spruce tree coarse-bark specimen "dark" bark of a spruce tree coarse-grained specimen "light" bark of a spruce tree

    In the exemplary embodiment, the slot trap 1 shown in FIG. 1 is equipped with two sources 10 for light. These sources 10 are arranged so that the radiation (light) impinges on the base body 2 and are reflected by this insect-specific, so that insects, especially bark beetles, are attracted reinforced and reach the slot trap 1.
    The insect-specific. Reflection (reflection spectrum) of at least one region of an insect trap, for example the insect trap 1 of FIG. 1, thus essentially corresponds to the reflection spectrum of a host of the insects to be attracted.
    Such hosts may be trees, parts of trees such as leaves and needles, but also the fur of animals.
    In any case, it is decisive that at least one region of the arrangement according to the invention has a reflection spectrum which corresponds in the reflection spectrum of a species-specific host of the insect to be attracted. The arrangement is therefore formed at least in an area insect-specific reflective.
    The sources 10 are held pivotably on a horizontal support 11 via downward-pointing rods 12, so that they can be aligned (pivoted) for optimum illumination of the slot trap 1. For protection against precipitation, a protective roof 7 may be provided on the carrier 11 via the sources 10.
    Each of the electromagnetic radiation emitting sources 10 is equipped in the embodiment with a plurality of LEDs 8, which can be activated independently of each other.
    On the main body 2 of the insect trap 1 plates may be arranged, which are formed insect-specific reflective. Such surfaces 9 (plates) are provided in the insect attracting devices (e.g., insect traps) shown in Figure 1 and those shown in Figures 2 through 8 when the device itself is not insect-specific reflective.
    In the context of the invention, it is contemplated that the supply of the electromagnetic radiation (light) emitting sources 10 with electrical energy through power storage, such as batteries or accumulators, by photovoltaic elements, optionally charging the power storage, or by an external power supply. In the case of an external power supply can be provided that the inventive arrangement is connected via power supplies and / or current transformers to a power grid.
    In Figs. 2 to 8 possible embodiments of insect attracting and possibly killing devices ("insect traps") are shown, which are equipped with plates 9 (as reflecting surfaces) whose reflection spectrum comes as close as possible to those of hosts of the insects to be attracted, ie insect-specific are reflective to form inventive arrangements.
    The embodiment of a device 15 according to the invention for attracting and killing insects shown in FIG. 2 comprises a three-legged frame over which a net with the shape of a three-sided pyramid is arranged. Within the network, a messenger 29 (semiochemical, such as pheromones) is arranged to attract insects.
    In detail, the device 15 of FIG. 2 may be configured as follows:
    The embodiment of the device 15 shown in FIG. 2 comprises a frame of three struts or uprights 21, which are connected to one another in a node formed by a shaped piece 22.
    The fitting 22 consists in the illustrated embodiment of three tubes, which are connected together at one end. The molding 22 may be, for example, an injection molded part made of plastic or metal. The uprights 21 are inserted into the tubes of the fitting 22 and clamped by means of screws.
    The three connected by the fitting 22 .Steher 21 are surrounded by a, formed in the illustrated embodiment of a network, enclosure 26, whereby an interior space 27 is provided, which is open towards the bottom. The sheath 26 extends in the illustrated embodiment over about 2/3 of the length of the uprights 21 down. The serving of 2 6 serving is with a
    Pesticides prepared, for example, has an insecticidal effect, so that the insects to be controlled, when they come into contact with the network of the envelope 26, die.
    In the interior 27 of the enclosure 26, on a cord 28 (or a hook) is a messenger (semiochemical, e.g.
    Pheromone) 29. Tim fitting 22 is mounted in the region of the upper end of a hook into which the cord 28 can be hung. The messenger 29 attracts insects to contact the mesh of the wrapper 26 and the active agent attached thereto. If the insects fly under the net of the enclosure 26 and enter the interior 27, sooner or later they will also come in contact with the prepared net of the enclosure 26, whereby the desired effect will occur.
    The uprights 21 can, as can be seen in Fig. 2, each be assembled from two telescopically telescoping tubes, wherein the lower tube is inserted into the upper tube and can be clamped there with the aid of a thumbscrew. This makes it possible to adjust the length of the uprights 21 the respective environmental conditions (sloping or uneven terrain) or wishes.
    The dimensions of the network of the sheath 26 and the upper tube are coordinated so that the network of the sheath 26 ends just above the screw or the thumbscrew. At the bottom of the network of the enclosure 26 21 strings or the like are mounted in the area of the uprights, with which the network of the enclosure 26 can be stretched down and tied to the screws.
    Eyelets 35 are attached, for example welded or screwed, can be inserted through the Erdnägel 36, pegs or the like to anchor the uprights 21 and thus the frame in the ground at the lower, near-ground ends of the uprights 21.
    The attracting of insects is reinforced in the embodiment of a device 15 shown in FIG. 2 in that 21 insect-attracting, insect-specific, reflecting surfaces 9 are arranged on one, two or all three sides of the net 26 and / or in the region of at least one post. These surfaces 9 are in the simplest case infrared radiation reflecting plates.
    The insect-specific reflective surfaces 9 may have approximately the size and shape of the side surfaces of the enclosure 26 and are preferably in the interior 7 of the device 15 (ie within the enclosure 26). In this case, insect-specific reflective surfaces 9 forming plates one, two or all three side surfaces of the sheath 26 may be assigned.
    Incidentally, in the embodiment shown in Fig. 2, the electromagnetic radiation (light) source 10 may be arranged, formed, operated and energized as described in connection with Fig. 1.

    In the segment funnel trap 50 shown in Fig. 4, a messenger (semiochemical such as pheromone) is housed.
    According to the invention, in particular, annular plates are arranged as insect-specific reflective surfaces 9 at the upper, further ends of the funnels 52.
    The supply of the sources 10 for electromagnetic radiation (light) can be carried out as described with reference to FIG. Incidentally, in the embodiment shown in Fig. 4, the radiation (light) source 10 may be arranged, formed, operated and energized as described in connection with Fig. 1.
    The insect trap formed as adhesive trap 60 shown in Fig. 5 comprises a substantially triangular prism 61, and inside the prism 61, there is provided a messenger (semiochemical such as pheromone), and the
    Trap 60 has an adhesive base 62. The finished glued and exchangeable adhesive base 62 has the result that insects (butterfly or sawflies) attracted by the optionally present pheromone and the insect-specific reflection insect attracting surfaces 9 in the case 60 and caught by the adhesive bottom 62.
    According to the invention, at least one but preferably both upwardly pointing walls 63 of the insect trap 60 shown in FIG. 5 each have at least one surface 9, in particular in the form of at least one plate, which reflects light in an insect-specific manner.
    The design and type of sources 10 and their supply of energy can be carried out as described with reference to FIG. 1. Incidentally, in the embodiment shown in FIG. 5, the electromagnetic radiation source (light) 10 may be arranged, formed, operated, and energized as described in conjunction with FIG. 1.
    The embodiment of a wing trap adhesive trap 60 shown in FIG. 6 which can be used as an insect trap in an arrangement according to the invention is similar to the insect trap of FIG. 5. In the insect trap shown in FIG. 6, the bottom 62 is angled and connected to the lower edges of the walls 63 by rings 64 which may be spring washers. On the walls 63 are insect-specific reflective surfaces 9, e.g. in the form of plates, provided. Incidentally, the trap trap adhesive trap 60 of Fig. 6 is constructed as described above for the adhesive trap 60 shown in Fig. 5. Incidentally, in the embodiment shown in FIG. 6, the electromagnetic radiation source (light) 10 may be arranged, formed, operated and energized as described in conjunction with FIGS. 1 and 5.
    In Fig. 7, an impact trap 70 is shown. The impact trap 70 has four star-shaped baffles 41. At the lower end of the baffles 41, a funnel 42 and below this a collecting vessel 43 is provided, in which the trapped insects fall. At least one of the baffles 41 is at least one insect-specific reflective surface 9 (plate). Incidentally, in the embodiment shown in FIG. 7, the electromagnetic radiation source (light) 10 may be formed, operated, and energized as described in conjunction with FIG. 1.
    The insect trap shown in FIG. 8, which can be used in an arrangement according to the invention, for example, is a trap lamp 80 (also called lantern trap). The trap lamp 80 has under a protective cover 81 on an upwardly open, downwardly conically widening part 82 and below a collecting container 83 for trapped insects. The protective roof 81 is connected to the other parts of the trap lantern 80 via rod-shaped connecting elements 84. At any point of the trap lantern 80 are surfaces 9, which are insect-specific reflective attached. In the example, annular, reflective surfaces 9 (plates) are arranged on the part 82. Incidentally, in the embodiment shown in Fig. 8, the electromagnetic radiation (light) source 10 may be arranged, formed, operated and energized as described in connection with Fig. 1.
    The spectrum shown in Fig. 12 gave good results. Especially the material FIB-Hell (black curve) has a similar to the bark running spectral pattern, but the color (beige) is atypical for bark beetle. FIB_12 is also advantageous in terms of color. The spectral curve shows a similar course as FIB-bright, but can still be optimized. For the coloring only natural dyes were used in FIB_12.
    In summary, an embodiment of the invention can be described as follows:
    An insect attracting device comprises an insect trap equipped with a messenger (semiochemical such as pheromone). The insect trap has at least one reflection surface whose reflection spectrum is substantially equal to the reflection spectrum of a host of insects to be attracted.
