(First embodiment)
As shown in FIGS. 1 to 3, the greenhouse 11 is formed in a square cylindrical shape at the bottom and a semi-cylindrical shape at the top, and both sides of the bottom are composed of a net made of a synthetic resin that serves as a shielding part 12. The front and rear surfaces are composed of a sheet 13 made of vinyl chloride resin. The net of the net is designed to have a side of 0.4 to 4 mm, and air permeability in the greenhouse 11 is ensured. In addition, sliding doors 14 are provided on the front and rear surfaces so as to enter and exit the greenhouse 11.

  Insect capturing devices 15 are provided on the outer net surfaces of both sides of the greenhouse 11. That is, the nets on both sides of the greenhouse 11 are arranged in the vertical direction, and are also used as the shielding portions 12 that block the movement of the insects. The insects have wings and refer to insects that fly in the air. Specific examples include whiteflies, kissing beetles, caterpillars, tobacco moths, slips, and aphids. If the net of the net is 0.4 mm on a side, most insects such as whiteflies and kissing beetles can be captured. If the net of the net is 4 mm on a side, it is possible to catch insects, tobacco moths and the like, and it is possible to prevent catching minute insects such as whitefly, slips and aphids.

  The outer surface of the shielding part 12 is formed so as to be inclined downward in a bowl shape by a net, and has an inclined part 16a extending obliquely upward along the outer surface of the shielding part 12 from the lower part of the front end. A guiding part 16 is provided to guide the insect to the upper side. The guiding portion 16 has the same mesh as that of the shielding portion 12, and the tip edge thereof is set at a certain height from the ground. It is desirable to set the leading edge of the guiding portion 16 at a low position because the insect has a habit of flying at a low position and moving upward at the shielding portion 12.

  At the upper end of this guiding portion 16, that is, at the upper corner of the rear end of the greenhouse 11, a trapping portion 17 that is formed in a rectangular box shape and whose lower portion is reduced in width toward the lower end is supported. It catches the insects that have moved. The insect trapping part 17 is also constituted by a net, and a bottom part of the insect trapping part (not shown) is provided.

  The shield part 12 below the inclined part 16a of the guide part 16 is provided with a roll part 18 in which a net is formed in a roll shape. As shown in FIG. 4, the roll portion 18 is formed in a spiral shape, and an interval holding member (not shown) is interposed in the overlapping portion 19 to form the insect insect introduction port 20, and the insect insect is indicated by an arrow in the figure. As shown, it is guided from the inlet 20 to the inside. As shown in FIGS. 1 and 2, the roll portion 18 extends rearward along the inclined portion 16 a at the upper end of the guide portion 16, and the upper end portion thereof is inserted into the insect catching portion 17 and enters the roll portion 18 and moves upward. The moving insects that have moved are guided into the trapping part 17. Although the guide unit 16 alone can guide the insect to the insect trapping part 17, by providing the roll part 18 in the guide part 16, the insect insect can be reliably transferred from the roll part 18 to the insect trapping part 17. Can increase the catching rate of insects.

  Now, the guide part 16 extended from the front end lower part to the rear end upper part is provided in the outer surface of the both sides of the greenhouse 11, and the roll part 18 is provided in the inside, and the insect trap part 17 is provided in the rear end upper part. . For this reason, when the insects flying around the greenhouse 11 try to approach the greenhouse 11, they pass under the guiding portion 16, hit the shielding portion 12, and rise along the shielding portion 12. Then, the insects move along the guiding part 16 to the rear upper part of the greenhouse 11 and enter the insect trapping part 17. Further, the insects that have risen along the shielding part 12 and entered the roll part 18 are guided to the rear upper part of the greenhouse 11 through the roll part 18 and enter the insect catching part 17. In this way, the insect can be captured in the insect trapping part 17 by using the habit of the insect that flies over the low position and moves obliquely upward.

  By the way, when the length of the shielding part 12 is 2 m, the height is 120 cm, the height of the front end of the guiding part 16 is 50 cm, and the height of the rear end is 120 cm, the number of trapped insects per day is 125. It was a head.

The effect exhibited by the above first embodiment will be described below.
-According to the insect trapping device 15 of the first embodiment, the shield 12 is arranged in the vertical direction and shields the movement of the insect, and extends obliquely upward along the shield 12, and the insect is moved upward. A guiding unit 16 for guiding and an insect capturing unit 17 connected to the upper end of the guiding unit 16 for capturing the insects are provided. For this reason, it is possible to intercept the insects approaching the greenhouse 11 with the shielding part 12, guide the insect part 16 obliquely upward, and catch the insect with the insect catching part 17. Therefore, the insect trapping device 15 of the first embodiment is effective for trapping insects over a wide range on both sides of the greenhouse 11.

-By the roll part 18, a bug insect can be guide | introduced in the roll part 18 and can be moved to the insect trap part 17, and the insect trapping effect of a bug insect can be improved further.
As described above, the insect capturing device 15 has a simple configuration and is inexpensive because it is only necessary to form the shielding unit 12, the guiding unit 16, the insect capturing unit 17, and the roll unit 18 with the same net.

In the protruding portion 16b, a horizontal frustum-shaped return preventing member 25 having a diameter reduced toward the insect capturing portion 17 side by a net is held. The return prevention member 25 prevents the insects that have entered the insect capturing part 17 from the guiding part 16 from returning to the guiding part 16 again. The return-preventing member 25 is particularly useful for bees such as stink bugs and wasps having high mobility.

  Further, a main body 26 of an anti-return member formed in an inverted truncated cone shape by a net is held at the central portion in the insect trapping portion 17, and a guide tube 27 formed in a cylindrical shape by the net at the lower end of the main body 26. Are connected. The main body 26 and the guide tube 27 constitute a return preventing member 28. The return prevention member 28 prevents the insects in the insect trapping part 17 from moving upward and returning to the guiding part 16. The lower part of the insect trapping part 17 is formed in an inverted conical shape, and its lower end part is formed in a cylindrical shape to serve as an insect discharge port 29. The insect catching portion 17 is divided into an upper space 30 and a lower space 31 by the return preventing member 28. The insect discharge port 29 is always closed and is opened only when the trapped insects are discharged.

  Now, the insects move upward along the guiding portion 16 and enter the upper space 30 of the insect capturing portion 17 through the return preventing member 25 from the protruding portion 16b. Since the return preventing member 25 is formed in the shape of a horizontal truncated cone that is reduced in diameter toward the insect trapping part 17 side, the insects that have once entered the insect trapping part 17 are unlikely to return to the guiding part 16 side. Further, the insects that have entered the upper space 30 of the insect trapping part 17 eventually descend through the return prevention member 28 and reach the lower space 31 of the insect trapping part 17. Since the return prevention member 28 is formed in the shape of an inverted truncated cone that is reduced in diameter toward the lower part, the insects that have once entered the lower space 31 are unlikely to return to the upper space 30. Therefore, according to the insect trapping device 15 of the second embodiment, the two return preventing members 25 and 28 effectively suppress the insects that have entered the insect trapping part 17 from the guiding part 16 from returning to the guiding part 16 again. can do.

An attracting source 32 that attracts insects by smell or light is supported at the center position of the shielding part 12 formed in a square box shape. The height of the attracting source 32 is set to 1.0 to 1.5 m, for example. The attracting source 32 that attracts the insect by the smell is a pheromone, and for example, pheromone that attracts the chafer bug is methyl (EEZ) 2,4,6-decatrienoate. The amount of pheromone used is set to about 3 g so that the insects can be attracted for one month. In addition, the effect of the pheromone extends to a range of about 200 to 300 m around the periphery, and can attract insects that are present in the range.

  In addition, (z, e) -9,11-tetradecadienyl acetate and (z, e) -9,12-tetradecadienyl acetate are used as the pheromone that attracts the clawed moth as a insect. The thing mixed by the mass ratio of 10: 1 is mentioned, The usage-amount is about 1 mg. The pheromone that attracts tobacco moth as a insect is as follows: (z) -9-tetradecenyl acetate, hexadecanal, (z) -11-hexadecenal, (z) -9-hexadece What mixed nyl acetate with the mass ratio of 100: 8: 3: 5 is mentioned, The usage-amount is about 10g. On the other hand, when the attracting source 32 is light, the power of the lamp is in the range of about 40 to 60 W, and the applicable range is about 100 m.

By the way, a 60 W mercury lamp was used as the attracting source 32 to catch insects overnight. As a result, it was possible to trap 1250, 1500, 2450, and 2690 headed insects in each insect trapping part 17, respectively. The traped insects were moths, bees, planthoppers, flies, spiders, mosquitoes, stink bugs, scarabs, etc., with the most being moths.
