A box-shaped lower casing 6 is attached to the lower side of the side, and the upper casing 5 and the lower casing 6 are arranged with a predetermined interval in the vertical direction, and a space formed by an interval provided between the upper casing 5 and the lower casing 6. A suction area W for attracting and sucking insects is provided.

  A carbon dioxide storage cylinder 40 for storing carbon dioxide as an insect attracting gas is disposed inside the support base 4. The carbon dioxide-containing cylinder 40 is connected to an insect attracting gas supply path 41 so as to be able to supply carbon dioxide. Further, the insect attracting gas supply path 41 is provided with a branching portion 42 in the middle of the first insect. It branches into an attracting gas supply passage 41a and a second insect attracting gas supply passage 41b.

  An attraction adjusting unit 43 is provided between the carbon dioxide containing cylinder 40 and the branching unit 42, and the attraction adjusting unit 43 can control the time and amount of carbon dioxide released from the carbon dioxide containing cylinder 40.

You may make it discharge | release from.

  The mixing ratio of carbon dioxide and octenol can be set to, for example, carbon dioxide: octenol = million parts by mass or more and about 1 part by mass.

  Here, the number of insects (here, mosquitoes) captured when carbon dioxide alone is used as the insect attractant gas of a general insect capturing device and when a mixed gas of carbon dioxide and octenol is used Table 1 shows the results of the comparative experiment. This experiment was conducted in a remote area, and the experiment was conducted for 24 hours.

  From Table 1, it is remarkable that the number of insects captured is greater when the mixed gas of carbon dioxide and octenol is used than when only the carbon dioxide is used.

  Therefore, carbon dioxide released from the second gas release unit 10 is attracted to insects (for example, female mosquitoes and gnats) who prefer carbon dioxide by carbon dioxide, and it has a higher attraction effect. Insects can be attracted to the suction area W by the mixed gas of carbon dioxide and octenol.

  The second gas discharge part 11 is covered with a staying part 14 composed of a cylindrical staying base 14a having a filter 14b at the top opening. The stay base 14a is made of a non-breathable material such as plastic, and the filter 14b is made of a net-like material such as a nonwoven fabric.

By sucking the air in the suction path 20, the worms can be sucked from the suction port 22 side of the suction path 20 toward the terminal capture unit 30 side. The suction fan 21 is driven by a drive motor (not shown).

  By providing the suction port 22 on the lower surface of the upper casing 5, it is usually possible to suck and capture insects more efficiently using the habits of insects trying to escape upward.

  The capturing unit 30 may be configured to capture by a method such as capturing by a capturing net or capturing insects by electric shock, or may be adhered to an adhesive body coated with a predetermined adhesive or wrapped in a predetermined bubble. And may be configured to capture.

  In the insect trapping device A2 configured in this way, the insect is attracted in advance from a relatively far distance by the attracting light 13, and then attracted to the vicinity of the insect trapping device A2 by the carbon dioxide released from the first gas discharge unit 10, Next, the mixed gas of carbon dioxide and octenol discharged from the second gas discharge unit 11 and the mixed gas heated by the heater 12 are attracted to the vicinity of the suction port 22 of the suction region W, and the insects are attracted from the suction port 22. Can be efficiently suctioned to improve the complementary angle efficiency.

  Here, in the insect trapping apparatus A2 of the present embodiment, the attracting adjustment unit 43 intermittently releases the insect attracting gas composed of carbon dioxide.

  Table 2 shows the results of a comparative experiment of the number of insects (here, mosquitoes) captured when the insect-attracting gas is released intermittently using a general insect capturing device and when it is released continuously. Show. This experiment was conducted in a remote area, and the experiment was conducted for 24 hours. In addition, the release of the test result (d) every 10 minutes for 2 minutes means that the gas mixture is continuously released for 2 minutes, then the release is temporarily stopped, and after 8 minutes from the release stop, it is released again for 2 minutes. Similarly, the other (a), (b), (c), and (e) are continuously released every 60, 30, 15, and 5 minutes for 2 minutes. , 15 and 5 minutes, the remaining time is a release pattern in which the release is stopped and then released again for 2 minutes.

  From Table 2, the insect attractant gas is continuously released when the insect attractant gas is released at regular intervals (for example, every 2 minutes every 5 to 10 minutes, preferably 2 minutes every 10 minutes). It is remarkable that the number of insects captured is larger than that of the case. Moreover, when the insect attracting gas is released intermittently, the consumption of the insect attracting gas can be reduced, so that the cost can be reduced.

  In the above-described embodiment, the attracting adjustment unit 43 is disposed on the upper side of the branching unit 42. However, the attraction adjusting unit is provided in each of the first insect attracting gas supply path 41a and the second insect attracting gas supply path 41b. May be provided.

  In the case where an attraction adjusting section is provided in each of the first insect attracting gas supply path 41a and the second insect attracting gas supply path 41b, for example, after stopping the release of carbon dioxide from the first gas releasing section 10, By controlling to release a gas mixture with a high attracting effect from the second gas discharge part 11, the amount of the insect attracting gas used can be reduced compared to the case of always releasing the insect attracting gas, thus reducing the cost. It is possible to attract worms with certainty.

You may comprise. Further, by making the upper surface of the lower casing 62 into a substantially mountain shape in this way, it is possible to stably form an upward air flow generated by the heater 12 provided on the upper surface of the lower casing 62.

  The insect trapping apparatus A6 of the sixth embodiment is a modification of the insect trapping apparatus A2 of the second embodiment, and has a feature in the arrangement of attracting means for attracting the insects.

  Similarly to the insect capturing device A2 of the second embodiment, the insect capturing device A6 of the present embodiment also includes a gas discharge unit 100 that discharges an insect attracting gas, a heater 12 that raises the ambient temperature, and an attracting lamp 13. The attraction means is configured to be combined, the suction means for sucking insects by the air flow generated by driving the suction fan 21, and the capture means including the capture unit 30 for capturing the sucked insects.

  In the insect trapping apparatus A6 of the present embodiment, a box-shaped upper casing 5 is provided on an upper part of a columnar support base 4 '. In particular, the upper casing 5 has a bottom surface on which the insect trapping apparatus A is installed. It is located at a height of 40 cm to 100 cm from the surface. Thus, a space is provided below the upper casing 5, and this space is used as a suction area W for attracting insects and sucking them by suction means. A bottom plate is attached to the lower end of the support base 4 'so that the insect trapping device A6 is in a stable standing posture.

  In the upper casing 5, a carbon dioxide storage cylinder 40 for storing carbon dioxide as an insect attracting gas, and a suction path 20 for sucking the insects attracted by the carbon dioxide released from the carbon dioxide storage cylinder 40, A suction unit configured with the suction fan 21 and a capturing unit 30 for capturing insects sucked by the suction unit are provided.

  The carbon dioxide containing cylinder 40 is connected to an insect attracting gas supply passage 41 so as to be able to send carbon dioxide. The insect attracting gas supply passage 41 is provided with an attraction adjusting portion 43 in the middle to release carbon dioxide. Control is possible.

  Further, the worm attracting gas supply passage 41 is provided with an octenol accommodating portion 44 for accommodating octenol as an insect attracting gas on the downstream side of the attraction adjusting portion 43, and released from the carbon dioxide accommodating cylinder 40 in this octenol accommodating portion 44. The mixed carbon dioxide and octenol are mixed, and the mixed gas is discharged from the gas discharge unit 100. In particular, the gas discharge unit 100 is provided with a discharge port on the outer surface of the upper casing 5.

  The starting end of the suction path 20 in the suction means is connected to a suction port 22 provided on the lower surface of the upper casing 5, the end is connected to the capture unit 30, and a suction fan 21 is provided near the end of the suction path 20. By sucking the air in the suction path 20, insects can be sucked from the suction port 22 side of the suction path 20 toward the terminal capture unit 30 side. The suction fan 21 is driven by a drive motor (not shown).

  A heater 12 is attached to the suction port 22, and a suction region W in the vicinity of the heater 12 is heated to generate a high temperature atmosphere.

  The capturing unit 30 may be configured to capture by a method such as capturing by a capturing net or capturing insects by electric shock, or may be adhered to an adhesive body coated with a predetermined adhesive or wrapped in a predetermined bubble. And may be configured to capture.

  At the upper part of the upper casing 5, an attracting lamp 13 for irradiating predetermined light is disposed, and a light emitting section 7 configured by covering the attracting lamp 13 with translucent glass or the like is provided.

  For the induction lamp 13, for example, a fluorescent lamp or a light emitting diode that irradiates ultraviolet light or visible light can be used, and the light of the induction lamp 13 is irradiated toward the periphery of the insect capturing device A6, so that the light is irradiated. You can attract insects by using the habits of gathering insects.

  Here, in the insect trapping apparatus A6 of this embodiment, when the attracting light 13 is provided only on the upper part of the upper casing 5, and when the attracting light 13 is provided on the upper part of the upper casing 5 and in the suction area W. Table 3 shows the results of a comparative experiment of the number of desired insects (here, mosquitoes) captured. In this experiment, an ultraviolet irradiator was used as an attracting light, and the experiment was conducted near a residential area. The experiment was conducted for 16 hours from 16:30 to 8:30. Moreover, the insect attractant gas which consists of a mixed gas of a carbon dioxide and octenol did not discharge | release.

  From Table 3, there is a significant difference in the number of insects captured when the attracting light 13 is provided in the upper part of the upper casing 5 and when the attracting light 13 is provided in the upper part of the upper casing 5 and in the suction area W. There is no, but if the trigger light 13 is installed on the upper part of the upper casing 5 among the captured insects, the capture rate of harmful insects such as mosquitoes that may cause harm to humans is high and captures efficiently On the other hand, when the attracting light 13 is provided in the upper part of the upper casing 5 and in the suction area W, the capture ratio of insects other than the pests is high and the capture efficiency is poor.

  By adjusting the brightness of the attracting light 13, it is possible to adjust the attracting range of the insects having the phototaxis that are attracted by the light. For example, in the case of about 200 lux, the radius of the attracting light 13 is 10 m. It is possible to attract worms having phototactic properties in the range of.

  Attraction of insects by an insect attractant gas consisting of a mixed gas of carbon dioxide and octenol is performed by sending about 50 ml / min to 500 ml / min of carbon dioxide from the carbon dioxide containing cylinder 40 by the attraction adjustment unit 43. In particular, the release of carbon dioxide may be intermittent release with a ratio of release time to stop time of 1: 4, for example.

  In the insect trapping apparatus A6 of this embodiment, the end of the insect attracting gas supply path 41 is connected to the side surface of the upper casing 5 located above the suction port 22 provided on the bottom surface of the upper casing 5, and the upper casing The insect attractant gas composed of a mixed gas of carbon dioxide and octenol is released from the side surface 5.

  This makes it easier to release the insect-attracting gas upward, as compared to the case of releasing upward and the case of releasing downward as shown in the table below. This is based on the finding that the trapping efficiency of insects (mosquitoes) is higher when the insect attracting gas is released upward.

  Here, the case where the insect attracting gas is released upward refers to the case where the insect attracting gas is released only from the second gas releasing unit 11 in the insect capturing apparatus A2 of the second embodiment described above.

  In the comparative experiment in the above table, the insect capturing device A6 of this embodiment and the insect capturing device A2 of the second embodiment are installed in the suburbs of the residential area, and the experiment implementation time is 16: 30-8: 30. It was 16 hours. Further, a comparative experiment was conducted with and without heating by the heater 12.

  It is preferable that the distance h1 from the bottom surface of the upper casing 5 is about 20 cm to 100 cm, and the attracting lamp 13 provided at the upper part of the upper casing 5 from the discharge port is the discharge port of the insect discharge gas of the gas discharge unit 100. It is desirable that the distance h2 is about 20 cm to 100 cm.

  When the distance h1 is out of the range of 20 cm to 100 cm, the attracting force for attracting the insects to the suction port 22 is reduced by the insect attracting gas, and when the distance h2 is out of the range of 20 cm to 100 cm, Since the attracting power for attracting insects to the extent attracted by the insect attracting gas is lowered by the attracting light 13, it is desirable to provide the gas discharge part 100 as described above.

  Here, in the insect trapping apparatus A6 of the present embodiment, a staying portion 14 'made of sponge is provided at the discharge port portion of the gas discharge portion 100 provided on the outer surface of the upper casing 5. That is, the mixed gas discharged from the gas discharge unit 100 is discharged after staying in the staying part 14 'for a certain time.

  The results of comparative experiments with and without the staying portion 14 'are shown in the table below.

  In the comparative experiment in the above table, an insect capturing device A6 with a retaining portion 14 'and a insect capturing device A6 with the retaining portion 14' removed are installed in the vicinity of a residential area, and the experiment implementation time is 16:30. The number of insects (mosquitoes) captured was compared for 16 hours at ~ 8: 30. In this experiment, the insect-attracting gas was released intermittently while the ratio of the release time to the stop time was 1: 1.

  As is clear from the experimental results, the retention portion 14 ′ provided in the gas discharge portion 100 has a larger number of captures than the case where the retention portion 14 ′ is not provided in the gas discharge portion 100, and the effectiveness of the retention portion 14 ′. It is to show.
