Abstract

PROBLEM TO BE SOLVED: To provide an insect trap for enhancing a capture efficiency, although this capture efficiency is extremely poor in the prior art because an inset flying in an insect-trapper can be incidentally trapped.SOLUTION: An insect trap 1 comprises an induction light source 2 for inducing an insect; an insect-trapping paper 4 for trapping the insect; and an enclosure 3 having an aperture 7 in a front/rear face and having said induction light source 2 and said insect-trapping paper 4 thereon. Said enclosure 3 is arranged therein with said induction light source 2, and the insect-trapping paper 4 is so arranged at an inclination with the insect-trapping paper 4 that the light from said induction light source 2 may be reflected.

Description

  The present invention relates to an insect trap that efficiently attracts insects with an attracting light source and captures the insects attracted with the trapping paper by devising the arrangement relationship between the attracting light source and the trapping paper.

Conventionally, as this type of insect trap, an opening is provided in the housing, and an attracting light source and insect trapping paper are provided inside, attracting insects with the light from the attracting light source, and capturing these attracted insects with trapping paper An insect trap (see, for example, Patent Document 1) that arranges insect trapping paper in a vertical type (see FIG. 4), a parallel type (see FIG. 5), and a U-shape (see FIG. 6) with respect to the attracting light source. Existing. However, the problem with these conventional insect traps is that the vertical type is not able to efficiently capture the insects that fly around the attracting light source by accidental trapping by the trapping paper.
Moreover, it was often seen that the insects caught fall by themselves due to the dead weight of the insects, and fall to the bottom of the insect trap. In other words, it was discovered that accidental capture often falls even if captured.
In the parallel type, it was found that insects that fly around in a large arc around the attracting light source were accidentally captured by a trapping paper, similar to the vertical type. In this case, insects may be caught trying to stay, but most of them caught only the insect's feet, so it was confirmed that they could fly around and escape after wearing. In other words, it was found that the parallel type has few wings and is easy to escape.
Furthermore, in the U-shape, the trapping paper itself must be formed in a special shape, which takes time and cost in production. That is, there is a problem that the insect trapping paper is not versatile.

Japanese Patent Laid-Open No. 2007-135527 (refer to the claims, detailed description of the invention, and FIGS. 1 to 11)

After being attracted to the attracting light source, the insect stays in the attracting light source (rarely dies on the attracting light source and falls under the trap). Furthermore, it remains on the support member of the attracting light source, the frame of the casing, the insect trapping paper, or the attracting light source. Walk around for a while from this place. The operation of jumping around the attracting light source is repeated. In the prior art described above, including Patent Document 1, only the incidental light source is accidentally captured by the insect trapping paper during the action of flying around or staying around these attracting light sources.
That is, it has been confirmed that the conventional insect trap can only capture accidentally, so it is extremely inefficient.
An object of the present invention is to provide an insect trap that increases the capture efficiency.

The first invention of the present invention capable of achieving the above object is an insect trap as described in claim 1, and is as follows.
Insect catcher comprising an attracting light source for attracting insects, an insect trapping paper for capturing the insects, an opening on the front and rear surfaces, and a housing having the attracting light source and the trapping paper inside The casing has a structure in which the attracting light source is disposed inside, and the insect trapping paper is disposed to be inclined toward the attracting light source so as to reflect light from the attracting light source.

A second invention of the present invention capable of achieving the above object is an insect trap as described in claim 2, and is as follows.
In addition to the invention described in claim 1, the attracting light source is arranged at the center of the casing, and the even number of the insect trapping papers are disposed so as to face the attracting light source and reflect the light from the attracting light source. It is the structure arrange | positioned inclined.

Since the insect trap according to the present invention has the configuration as described above, the following effects are achieved.
(1) Insects having positive phototaxis gather in an attracting light source in the trapping device while meandering. Thereafter, the insects fly around like an attracting light source or stay around it (when observed, the attracting light source itself, the frame of the catching device, the attracting light source, and the support member of the catching paper) Often stays on a guard.) Thereafter, the insects are captured by an insect trapping paper made of an adhesive sheet for the behavior of the insects around the attracting light source.
In the present invention, the insect trapping paper is disposed obliquely with respect to the attracting light source, so that the attracting light source, for example, ultraviolet rays are not shielded by the trapping paper but reflected at a wide angle and reflected at the front surface of the trapping paper. As a result, the ultraviolet irradiation rate for the insects is increased by reflection, so that the insect attracting efficiency is increased.
(2) In particular, large flies such as powder flies actively try to stay on the trapping paper, and the trapping paper is slanted so that it touches its wings and cannot escape.
(3) Among the inventions described in claim 2, the trapping efficiency can be further increased by arranging four trapping papers in an X shape and focusing on the attracting light source among the even number of sheets. .
(4) Large-scale fly flies that are difficult to capture with conventional insect traps can be captured effectively by installing the trapping paper at an angle.

  Insect catcher comprising an attracting light source for attracting insects, an insect trapping paper for capturing the insects, an opening on the front and rear surfaces, and a housing having the attracting light source and the trapping paper inside In the above, the case is an insect trap in which the attracting light source is disposed inside, and the trapping paper is disposed to be inclined toward the attracting light source so as to reflect light from the attracting light source.

The 1st Example in the insect trap of this invention is shown, (a) is the whole schematic perspective view of an insect trap, (b) is a schematic perspective view of the cover body in a housing | casing, (c) is a frame body of insect trap paper. The schematic perspective view which shows the state attached to (d) is a schematic side view of (c). The 2nd Example in the insect trap of this invention is shown, It is a schematic side view for demonstrating roughly the mode of reflection of the light source in the relationship of an attracting light source and insect trap paper. In the insect trap of the said 2nd Example, it is explanatory drawing of the action pattern of the insect (for example, fly) in the vicinity of an insect trap obtained by observation. It is a schematic side view of the vertical type insect trap which arranged the insect trap paper in the conventional insect catcher perpendicularly with respect to the attracting light source. It is a schematic side view of the parallel type insect trap which arranged the insect trap paper in the conventional insect trap parallel to the attracting light source. It is a schematic side view of the U-shaped insect trap arrange | positioned so that the insect trap paper in the conventional insect trap may be covered with an arc shape with respect to the attracting light source.

First, a conventional insect trap will be briefly described.
Insects that have phototaxis to the insect trap gather in the attracting light source while meandering. After that, it will fly around like an attracting light source and stay in the surrounding parts (usually, it often stays in the attracting light source itself, the case of the insect trap, and the support frame). Conventional insect trapping paper captures insects accidentally in response to insect flying behavior around the attracting light source.
Furthermore, the conventional specific insect trap will be described. The vertical trap shown in FIG. 4 accidentally captures the insect flying around the attracting light source. It turns out that there are many accidental captures, and even if captured, they often fall.
The parallel insect trap shown in FIG. 5 accidentally captures an insect flying in a large arc around the attracting light source. However, because it catches only insect legs, it may fly after wearing. Furthermore, it was found that there were few catches of wings and it was easy to escape.
The U-shaped insect trap shown in FIG. 6 has a special shape of the trapping paper itself, which is expensive to manufacture and takes too much cost and labor. That is, there is no versatility of insect trapping paper.
As described above, these conventional insect traps depend on accidental trapping, and generally have low trapping powers such as large mosquito flies.

Next, the result of observing the behavior pattern of flying large flies using the insect trap of the present invention will be described.
As shown in FIG. 3, when the large fly was attracted by the attracting light source 2 and entered the insect trap 1, it mainly took the following actions.
(A) Stay in the attracting light source 2 (rarely dies on the attracting light source 2 and falls below the trap).
(B) Jump around the attracting light source 2.
(C) Stays on the housing 3 and the support frame 5.
(D) Walk for a while from the place you stayed.
(E) The insect trapping paper, which is one of the features of the trapping device of the present invention, is slanted and stays directly on each trapping paper arranged in an X shape (if the trapping paper has no adhesive surface, the fly will walk) Also confirmed.)
That is, it has been found that the insect trapping paper itself has a perch effect and is easily captured.
This is a big difference in the effect compared with the conventional insect trap, and in the conventional trap, the fly caught around the attracting light source only accidentally captured by the trapping paper, but the present invention In the insect trap, it is possible to confirm that the insect light stays on the trapping paper directly by the reflected light of the attracting light source 2 or the fly staying on the housing 3 or the support frame 5 moves to the trapping paper disposed obliquely while walking around. An increase in capture opportunities was confirmed.

Next, an embodiment of the insect trap of the present invention will be described with reference to the drawings.
FIG. 1 shows an insect trap 1 in which an insect trap paper 4 is arranged in an X shape with respect to an attracting light source 2. This insect trap 1 is an insect trap 1 that emits an attracting light source 2 to the outside of the trap 1 and attracts insects into the trap 1 by this attracting light.
The insect trap 1 includes a housing 3 composed of a substantially rectangular lid 6 and a support frame 5, an attracting light source 2 for attracting insects inside the housing 3, and a trap for attracting the attracted insects. A trapping paper 4, a lighting ballast (not shown) of the attracting light source 2, the attracting light source 2, and a support frame 5 of the trapping paper 4 are arranged.
The housing 3 has openings 7 on the front and rear surfaces, and an attracting light source 2 is disposed at a substantially central portion of the housing 3 and is X-shaped so as to face the attracting light source 2 radially. Four trapping papers 4 are provided.
By adopting such a configuration, the insect trapping paper 4 is a light source of the attracting light source 2, for example, the insect trapping paper 4 serves as a reflector without shielding the ultraviolet rays and reflects the ultraviolet rays to a wide angle (see FIG. 2). The ultraviolet irradiation rate is increased.

Here, a second embodiment of the insect trap 1 of the present invention will be described with reference to FIG.
The difference from the first embodiment is that the trapping paper 4 is arranged in an X shape, and two trapping papers 4 are used to face the attracting light source 2 and obliquely as shown in FIG. Since the light is irradiated back and forth from the attracting light source 2 at the same time, and the insect trapping paper 4 is inclined, it is reflected and irradiated with light at a wide angle. It is easy to be attracted to the inside, and as a result, the capture rate increases.

  As described above, the first and second embodiments have been described with respect to the four insect capturing papers 4 and the even number of the two insect capturing papers 4. If the 4 is disposed obliquely, the insect trapping paper 4 is inclined, so that the light is reflected and irradiated at a wide angle, so that the insect is easily attracted into the trap 1. As a result, the capture rate increases.

  In selecting the color of the insect trap 1, the research of Professor Philip G. Keller at the University of Florida found that blue insects attracted insects more preferentially. Blue was adopted. By using this blue color, it has been found that when used in a food processing factory, it has a role to prevent foreign matter from being mixed when the insect trap 1 is broken, and is easy to find when mixed in food.

  By selecting the type of irradiation light of the attracting light source, it is possible to change to an insect trap corresponding to the insect to be captured.
