Description

  The present invention relates to a trap for fruit tree stink bugs that attracts and captures fruit tree stink bugs by an attracting pheromone, and in particular, can capture fruit tree stink bugs efficiently in a short time, and is easy to assemble and install, and is easy to maintain and manage. It relates to a trap for fruit tree stink bugs.

  Fruit tree stink bugs are typical flying pests that do not propagate in orchards, but move or invade into coniferous orchards. Fruit tree stink bugs, for example, occurred extensively nationwide in 1973 and have repeatedly caused enormous fruit damage. It is the most important group of fruit tree pests, mainly consisting of Chabanae stink bugs, Kusagi stink bugs, and Tsuya Aokamushi. These stink bugs overwhelm with adults and become the source of the next spring, damage various fruit trees from the next spring to the beginning of the next summer, and new adults are generated from the beginning of the next summer, and this new adult overwinters. .

  In fruit tree stink bugs having such an ecology, it has been confirmed that both male and female adults are attracted by aggregated pheromones released by male adults. In addition, it has been confirmed that the collective pheromone is not only used for attracting female adults but also used for teaching other adults about food. And since the fruit tree stink bugs are flying pests, it is extremely effective for control to know the flying time and amount in advance, it can be installed in a wide area that allows it, and the catcher for occurrence prediction that is easy to handle Development is desired.

  Conventionally, killing lights and basin-type insect traps have been used as this type of trap. The killing lamp uses light such as a 100 W mercury lamp as an attraction source, and the fallen individual passes through a funnel-shaped device and is captured in a large container. Not only stink bugs, but many types of nocturnal pests with phototaxis are targeted. The basin-type insect trap uses an artificially synthesized lure containing the chafer bug assemblage pheromone. The attracted stink bugs are captured by falling into a container filled with water and drowning.

Further, as a conventional trap for capturing fruit tree stink bugs, there is a dry trap according to the application of the present applicant. This dry trap is composed of a stink bug attracting part for attracting fruit tree stink bugs by a collecting pheromone and a stink bug catching part for catching stink bugs, and the stink bug catching part is arranged above the stink bug attracting part. The stink bug attracting portion has a collecting pheromone inside thereof, and has a hole or slit for discharging the collecting pheromone in the stink bug attracting portion (see, for example, Patent Document 1).

  1-5, the trap 1 of the fruit tree stink bugs of this embodiment is provided with a stink bug attracting part 2 that attracts fruit tree stink bugs by an aggregate pheromone and a stink bug capturing part 3 that traps the fruit tree stink bugs. The overall shape of the trap is a cone-shaped shape with a wide lower portion and a narrow upper portion. The stink bug capturing section 3 is disposed above the stink bug attracting section 2 and includes a lower funnel section 4 and an upper container section 5. The stink bug attracting portion 2 includes a skirt portion formed by assembling four skirt plates 11, 11. These skirt plates are formed from a plastic plate having a thickness of about 2 mm, and preferably a light-transmitting plastic plate is used. That is, even if it is not transparent, it should just have translucency. In particular, as a plastic plate having translucency, a polypropylene resin having appropriate strength and flexibility is preferable.

  Here, the skirt plate 11 will be described in detail. The skirt plate 11 has a substantially trapezoidal shape having a lower side portion 12 and an upper side portion 13, and two inclined side portions that connect the lower side portion and the upper side portion. 14 and 15. The angle formed by the two inclined sides is set to about 40 degrees. The lower ends of the two inclined side portions are parallel side portions 16 and 16. As a result, when the four skirt plates 11, 11,... Are connected, four gaps 17, 17,. Further, one inclined side portion 14 is a connecting side portion 18 bent at a right angle, and through holes 19, 19... Into which fixing tools such as fixing pins are inserted are formed. And the through-holes 20, 20 ... which oppose the through-holes 19, 19 ... along the other inclined side part 15 are formed. The four skirt plates 11, 11... Are connected by a fixing tool 21 such as a fixing pin with the other inclined side portion 15 overlapped on the adjacent connecting side portion 18. As the fixing tool 21, in addition to the fixing pin, an appropriate fixing means such as a split pin, a screw and nut, and a thumbscrew can be used.

  In addition, a hook part 22 for coupling to the funnel part 4 constituting the stink bug capturing part 3 is formed protruding from the upper side part 13. The hook portion 22 is bent at an angle of about 20 degrees with the main body portion of the skirt plate 11, and when the trap 1 is assembled, a vertical portion 22a that extends in the vertical direction and a horizontal flange portion 22b that extends in the horizontal direction from the vertical portion. And. The hook portion 22 is formed integrally with the skirt plate 11 and can be bent inward by an elastic plastic plate.

  A through hole 23 is formed in the center of the skirt plate 11, and fruit tree stink bugs that have stopped on the surface of the skirt plate can move to the back surface of the skirt plate through the through hole 23. The four skirt plates 11, 11,... Are formed of a transparent polypropylene resin as an example, and the front and back surfaces thereof are embossed with a rough surface as an uneven surface. In the present embodiment, the surface finish is performed so that the surface roughness Ra is about 3.3 μm. It should be noted that the surface roughness is not limited to the above example, and can of course be set as appropriate at Ra = 3.0 to 4.0 μm. The four skirt plates 11, 11,... Constitute a path along which fruit tree stink bugs move.

  The stink bug attracting portion 2 is squeezed upward as a stink bug capturing portion 3 on the upper side of the skirt portion formed from the four skirt plates 11, 11,..., That is, the funnel portion 4 having a tapered cross-sectional area that decreases upward. And a container portion 5. The funnel part 4 has a function of concentrating and guiding fruit stink bugs attracted by an aggregation pheromone, which will be described later, to the container part 5 of the stink bug trapping part 3. And a central quadrangular frustum-shaped tapered portion 42 that is continuous with the upper side, and an upper quadrangular columnar passage portion 43 that is continuous therewith. That is, the funnel portion 4 has a rectangular pyramid-shaped tapered portion 42 continuous on a large rectangular column-shaped introduction portion 41 below, and further a small square column-shaped passage portion 43 continuously on the upper side. It has a shape that squeezes toward, and the internal space is tapered.

  A flange portion 44 for hanging the trap is projected from the rectangular column-shaped introduction portion 41 below the funnel portion 4 toward the outer peripheral side, and a hole 45 into which a rope or the like is inserted is inserted into the flange portion. Is formed. Further, a triangular receiving plate 46 is fixed to the upper end of the truncated pyramid-shaped tapered detail 42, and the upper side of the receiving plate is configured to receive the bottom surface of the container portion 5 of the stink bug capturing unit 3 described later, A container part can be supported stably. The inner surface of the funnel portion 4 configured in this way constitutes a path for the attracted fruit tree stink bugs to move. The same concavo-convex processing is given.

  On the inclined surface of the truncated pyramid-shaped tapered portion 42 of the funnel portion 4, slits 47, 47... Into which the horizontal flange portions 22 b of the hook portions 22, 22. Is formed. Therefore, the stink bug attracting part 2 is suspended and connected to the funnel part 4 by inserting the hook parts 22, 22 ... of the skirt plates 11, 11, ... into the slits 47, 47 ... of the funnel part 4. It has become. The inner surfaces of the hook portions 22, 22... Also constitute a path for the attracted fruit tree stink bugs to move, and the inner surface is subjected to the uneven processing similar to the skirt plate.

  The container part 5 of the stink bug capturing part 3 includes a rectangular columnar container body 50 and a lid 60 that covers the upper opening of the container body. The container main body 50 is formed with a quadrangular columnar passage portion passing through the container main body in the vertical direction at the center. This passage portion has a large-diameter cylindrical portion 51 in which a quadrangular columnar passage portion 43 protruding above the funnel portion 4 is fitted, and a small-diameter cylindrical portion 52 having a smaller diameter than the large-diameter cylindrical portion 51. Is set smaller than the height of the container body 50. Accordingly, the small-diameter cylindrical portion 52 is separated from the inner surface of the lid portion with the lid portion 60 covered on the container body 50, and a gap through which fruit tree stink bugs can pass is formed, and the internal space of the container body 50 is the funnel portion 4. It communicates with the interior space. The inner surface of the small-diameter cylindrical portion 52 forms a path along which the fruit tree stink bugs that are attracted and passed through the passage portion 43 move, and the inner surface is also provided with the same unevenness as the skirt plate. Note that the inner surface of the large-diameter cylindrical portion 51 that is continuous with the small-diameter cylindrical portion 52 may also be subjected to uneven processing.

  On the bottom surface of the container main body 50, a large number of holes 53 for ventilation, for example, about 2 mm in diameter are arranged so that the captured fruit tree stink bugs cannot escape. And the flange part 54 extended outward is formed in the upper part of the container main body 50, and the eight hemispherical protrusions 55 are formed in the upper surface of a flange part. For this reason, the container main body 50 and the lid 60 are separated from the flange portion 54 and the inner surface of the lid 60 due to the projections 55 coming into contact with each other, and the inside of the container main body 50 can be ventilated together with the vent hole 53. It has become.

  The lid portion 60 positioned above the container body 50 has a configuration in which a wall portion 62 is suspended from the outer periphery of the flat plate portion 61 and the flange portion 54 of the container body is fitted into the wall portion with a gap. ing. Further, four pressing protrusions 63, 63... Are formed downward from the bottom surface of the flat plate portion 61, and these pressing protrusions are set to contact the inner peripheral surface of the container body 50. For this reason, in a state where the lid 60 is put on the container main body 50, the pressing protrusions 63, 63... Are brought into contact with and locked on the inner peripheral surface of the container main body and are not easily dropped off. Thereby, escape of the fruit tree stink bugs captured in the container main body 50 is prevented. The container body 50 is preferably formed of a transparent resin, whereby the amount of fruit tree stink bugs captured inside the container body can be easily grasped. Further, it is preferable that the lid 60 is also formed of a transparent resin.

  An aggregation pheromone agent 70 for attracting fruit tree stink bugs is attached to the trap 1. The aggregate pheromone agent 70 is a tube type impregnated with aggregate pheromone. Aggregate pheromone is equivalent to the main component of aggregate pheromone released by adult male chaban bugs, and this aggregate pheromone can attract fruit tree stink bugs such as chafer and stink bugs .

  The collective pheromone agent 70 is supported by being wound around a T-shaped support composed of the collective pheromone agent hanging rod 71 and the collective pheromone agent support rod 72. The collecting pheromone agent hanging rod 71 is placed on the upper end of the small diameter cylindrical portion 52, and the collecting pheromone agent support rod 72 is suspended in the small diameter cylindrical portion 52, the passage portion 43 of the funnel portion 4, the tapered portion 42, and the introduction portion 41, The lower end portion is located at the center of the skirt portion 2. In this way, the collective pheromone agent 70 is arranged inside the skirt plates 11, 11... Constituting the stink bug attracting part 2. The position of the assembly pheromone agent may be any position as long as it is inside the skirt plate. For example, the assembly pheromone agent is sandwiched and fixed around the through-hole 23 of the skirt plate 11 like a clip, and a part thereof is outside the skirt plate. It may be supported by protruding. The suspension rod 71 and the support rod 72 that support the collective pheromone agent 70 configured in this way constitute a path through which fruit tree stink bugs are attracted and moved upward. Therefore, it is preferable that the surface of the aggregate pheromone suspension rod 71 and the aggregate pheromone support rod 72 are also subjected to uneven processing in the same manner as the skirt plates 11, 11.

  The assembly operation of the fruit tree stink bug trap 1 of the present embodiment configured as described above will be described below. First, as shown in FIG. 4, the connecting side portion 18 of the two skirt plates 11, 11 is overlapped with the inclined side portion 15, and a fixing tool 21 such as a fixing pin is inserted into the through holes 19, 20. The two skirt plates 11 are connected. Next, the inclined side portion 15 of the third skirt plate 11 is overlapped with the connecting side portion 18 of the second skirt plate 11, and a fixing tool 21 is inserted into the through hole and connected. Finally, the connecting side portion 18 of the fourth skirt plate 11 is overlapped with the inclined side portion 15 of the third skirt plate 11 so that the fixture 21 is inserted into the through hole, and the remaining inclined side portion and connecting side portion are inserted. A fixing tool 21 is inserted into the through hole in the overlapping portion and the four skirt plates 11, 11,... Are connected to form a square frustum-shaped skirt portion. The four skirt plates 11, 11,... Are flat and can be transported in a stacked manner, so that the trap 1 can be easily moved and installed.

  The skirt portion thus configured has four gaps 17, 17... At the lower end portion. The fruit tree stink bugs that have stopped on the surface of the skirt board 11 through these gaps can also move to the back side. Since the four skirt plates constituting the skirt portion project upwardly from the four hook portions 22, 22 ..., when the funnel portion 4 is put on the outside of the hook portion from above, the hook portion is placed on the inclined surface of the funnel portion. When the funnel portion 4 is pressed downward, each hook portion is slightly elastically deformed inward, and the horizontal flange portion 22b is fitted into the slit 47 so that the funnel portion 4 and the skirt plates 11, 11,. Thereafter, the container part 5 of the stink bug capturing part 3 is fitted into the outer periphery of the passage part 43 at the upper part of the funnel part 4. The container body 50 of the container part 5 can be installed on the funnel part 4 in a stable state because the rectangular columnar passage part 43 is fitted into the large-diameter cylindrical part 51.

  In the fruit tree stink bug trap 1 of the present embodiment configured as described above, the container part 5 of the stink bug trapping part 3 is externally fitted to the rectangular column-shaped passage part 43 above the funnel part 4 located at the center in the vertical direction. Then, the lid 60 is put on the upper part of the container body 50 of the container part. Then, the hook portions 22, 22... Of the skirt plates 11, 11,... Are inserted into the slits 47 of the funnel portion 4, the skirt portions are connected in a suspended state, and the entire height is assembled to about 50 cm. The trap 1 assembled in this way is used by suspending the rope 75 or the like to the flange portion 44 protruding from the outer periphery of the funnel portion 4 and suspending the rope 75 or the like. And the aggregation pheromone agent 70 is suspended and supported inside the skirt plates 11, 11... Constituting the stink bug attracting part 2. Since the trap of the present invention can be installed by hanging on a fence or a tree branch or the like and can be installed in a wide area, it is possible to easily predict the occurrence of fruit tree stink bugs and the like.

  The trap 1 is preferably installed at a flat, well-ventilated and line-of-sight position 50 to 100 m away from the orchard. By installing at such a distance, damage to the orchard by the fruit tree stink bugs attracted by the aggregate pheromone agent 70 can be prevented. Moreover, it is preferable that the trap 1 is installed so that the aggregate pheromone agent 70 is located at a height of 150 to 160 cm from the ground.

  When the collective pheromone agent 70 is suspended inside the trap 1, the fruit tree stink bugs are attracted and fly in response to this, and stop on the skirt plate 11 of the stink bug attracting part 2. After the fruit tree stink bugs stop around the pheromone source and have the habit of walking and moving upward, they move up along the skirt board 11. The fruit tree stink bugs can move to the back side of the skirt plate 11 through the gap 17 and the through hole 23. Since the front and back surfaces of the skirt board 11 are roughened, and the fruit tree stink bugs can rise without falling on the front and back faces of the skirt board 11, almost all the fruit tree stink bugs that have stopped on the skirt board 11 are in the path. It rises along the front and back surfaces of a certain skirt plate, and is guided to the funnel portion 4 through the hook portions 22, 22.

  Fruit tree stink bugs guided to the funnel part 4 rise along the inner peripheral surface of the funnel part, are collected through the introduction part 41, the tapered part 42 and the passage part 43, and pass through the small diameter cylindrical part 52 of the container body 50. Move. Since the introduction portion 41, the tapered portion 42, the passage portion 43, and the small-diameter cylindrical portion 52 are also processed to be uneven, the fruit tree stink bugs can rise without falling. Since the container body 50 is provided with a large number of holes 53 for ventilation, the temperature inside the container part 5 is prevented from rising, and the fruit tree stink bugs can actively walk. The fruit tree stink bugs that have reached the upper end of the small-diameter cylindrical portion 52 lose their place, fall over the upper end surface, and fall into the container body 50 of the stink bug capturing unit 3. The fallen fruit stink bugs are killed by an insecticide placed in the container body 50. Since the container body 50 has a large number of holes 53 for ventilation, the captured fruit tree stink bugs are rotted and damaged. There is no.

  Here, the comparison of the slipperiness of the surface with respect to the installation angle of the skirt plate and the degree of drop when the larvae are moved by walking will be described with reference to Table 1. The surface roughness 0 shown in Table 1 indicates the surface state of the plate material when the surface of the plastic plate was not polished, and the surface roughness was 0.101 μm. A surface roughness of 1 was obtained by lightly polishing the surface of the plate material, and the surface roughness was 1.203 μm. Moreover, the surface roughness 2 grind | polished the surface of the board | plate material so that an unevenness | corrugation might come out, and the surface roughness was 3.309 micrometers. Then, the male and female of the beetle stink bug were attached to plastic plates inclined at angles of 60 °, 90 °, 120 ° and 135 °, and the ratios of falling were compared.

  As is clear from Table 1, in the case of males, 50% of the surface roughness was 0 when the angle was 60 °, and 66.7% was dropped when the angle was 90 °. When the surface roughness was 1, the drop was 0% when the angle was 60 °, and 77.8% was dropped when the angle was 90 °. Moreover, in the surface roughness 2, when the angle was 60 ° or 90 °, the male stink bug did not fall and all the stink bugs were stably walking. In the case of a knife, when the surface roughness was 0, 60% dropped when the angle was 60 °, and 50% dropped when the angle was 90 °. At a surface roughness of 1, 30% of an angle of 60 ° dropped, and 66.7% of an angle dropped 90 °. Moreover, in the surface roughness 2, it did not fall when the angle was 60 °, and 5.6% dropped when the angle was 90 °. Thus, by setting the surface roughness to about 3 μm with a surface roughness of 2, it was confirmed that the fruit tree stink bugs could be prevented from dropping at the stink bug attracting part and the number of catches was greatly increased. Further, even in the case of 120 ° and 135 °, which are overhanging states with reverse inclination, it was apparent that the drop rate tended to be significantly reduced when the surface roughness with a surface roughness of 2 was about 3 μm.

  Here, the number of captured chaper bugs and brilliant bugs by the fruit tree stink bug trap 1 of the present embodiment and the conventional trap shown in Patent Document 1 will be described with reference to Table 2. Table 2 shows the number of individuals when the aggregate pheromone agent 70 is suspended inside the skirt plate of the trap 1 and 150 days have passed outdoors. In the old type of catcher, there were 86 males and 157 females of Chabanae stink bugs in total, 243, whereas in the trap 1 of the present invention, there were 230 males and 399 females of Chabanae stink bugs in total, 629. In addition, as for the blue stink bug, there were 21 males and 25 females in the old type trap, totaling 46, whereas in the trap 1 of the present invention, there were 102 males and 98 females, totaling 200. Thus, the trap 1 of the present invention was able to capture fruit tree stink bugs about 2 to 4 times the old trap.

  In addition, Table 3 shows the recovery time for the fruit tree stink bugs of the above-described trap 1 of the present invention and the old trap. Table 3 shows the time required for one recovery per trap. As is clear from Table 3, the time for collecting fruit tree stink bugs per hour was 52.5 seconds for the old type catcher, while 10.9 seconds was required for the catcher 1 of the present invention. Thus, the recovery time could be reduced to about one fifth.

  Furthermore, in the trap 1 according to the present invention, the number of fruit stink bugs captured was compared between a skirt plate and a funnel portion formed of a yellow plastic plate and a transparent plastic plate. As shown in Table 4, in the case of the yellow plastic plate, 88 males and 132 females in total are 220 males, whereas in the case of the transparent plastic plate, there are a total of 220 males. There were a total of 629 males with 230 males and 399 females. In addition, in the case of the yellow stink bug, in the case of the yellow plastic plate, there were a total of 67 males with 32 males and 35 females, whereas with the transparent plastic plate, a total of 200 males with 102 males and 98 females. Met. Thus, it was possible to increase the number of captures by about three times by using a transparent plastic plate, that is, a plate material having translucency.

  In the embodiment described above, the aggregate pheromone agent 70 is wound around and supported by the support composed of the suspension rod 71 and the support rod 72. However, the aggregate pheromone agent 70A shown in FIG. As described above, a wire, a string or the like hooked on the upper side portion 13 of one skirt plate 11 is also bent and bent in a U shape at the lower end of the support 74 and is visible from the through hole 23 of the skirt plate 11. It can also be configured to be arranged at a position.

  Although one embodiment of the present invention has been described in detail above, the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention described in the claims. Design changes can be made. For example, the stink bug attracting part has a quadrangular frustum shape composed of four skirt plates, the intermediate funnel part has a quadrangular frustum shape, and the upper container part has a rectangular parallelepiped shape, but the stink bug attracting part has a conical shape. It is also possible to form a trapezoidal shape, and the intermediate funnel portion may have a shape based on a truncated cone, and the upper container portion may be formed in a cylindrical shape. As described above, any shape may be used as long as it attracts the fruit tree stink bugs downward and has a stink bug trapping portion tapered upward.

  Although an example of embossing has been shown as the concavo-convex processing of the skirt plate, rough surface processing by file or surface processing by sandblasting can also be used. Further, a surface treatment by knurling may be performed to prevent the fruit tree stink bugs from falling when walking upward.

  As an application example of the present invention, a light source such as a light emitting diode can be used for the stink bug attracting part or the stink bug capturing part, and more fruit tree stink bugs can be captured by attaching the light source. Moreover, it is applicable not only to the capture of fruit tree stink bugs but also to other pests.
