Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a fly attractant used in a trap or the like for catching a fly.

[0002]

Flies occur from livestock houses, poultry houses, landfills, kitchens and the like. Extermination is performed on such flies. However, flies have large flight ability, and in many cases, the arrival efficiency and action effects of insecticides are not sufficient. Therefore,
The fly attracts the insecticide efficiently by the attractant,
Invitations are being trapped in traps.

Under the present circumstances, flies are likely to collect in various foods, and no attractant is particularly effective as a fly attractant. Moreover, the attracting effect of the attractant may be reduced depending on the type of kitchen garbage, and the attracting effect may be reduced due to the difference in the usage state of the attractant.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a fly attractant which exhibits a higher attracting effect than conventional attractants and can exert an attracting effect in any use situation.

[0005]

[Means for Solving the Problems] The inventors of the present invention have conducted investigations to solve the above problems, and as a result of investigating the effect of attracting flies to various foods, the specific food has a higher effect of attracting than meat granules. The present invention has been completed and the present invention has been completed.

That is, the present invention provides the following fly attractant: (1) Onion, clam, scallop or egg yolk powder, or at least one of these extracts as an active ingredient (2) A fly attractant (2) A fly attractant (3), which comprises a mixture of an onion extract and a clam extract as an active ingredient, and (1) or (2) above. ） Fly attractant

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION Each component of the fly attractant of the present invention (hereinafter, also simply referred to as "attractant") will be described below.

In a first form, the attractant of the present invention contains onion, clam, scallop or egg yolk powder or an extract obtained by extracting these powders with a suitable solvent as an active ingredient.
These active ingredients may be used alone or in combination of two or more.

In a second form, onion extract and clam extract are contained as active ingredients. Here, the onion extract and the clam extract may be a mixture of both as one attractant, or each may be a separate attractant,
You may mix at the time of use.

Each of the above-mentioned attractants may be used in combination with various additives as long as the effects of the present invention are not impaired. For example, a bactericide, a fungicide, a preservative, an antioxidant, and an anti-UV agent. , Spreading agents, chelating agents, thickeners, ingestion inhibitors, fragrances (acetoin etc.), sex pheromones of flies (eg (Z)-
9-tricosene) or other attractants (eg, methyl phenylacetate, ethyl phenylacetate, propyl phenylacetate, phenethylacetate phenylacetate, etc.) and the like.
In addition to this, the attractant may be colored in a reddish color or the like with a pigment in order to enhance the attracting activity of the fly. Other food attractants may also be used, such as fruits (melons, bananas, strawberries, etc.) and their extracts and processed products, brewed products (black vinegar, miso, soy sauce, etc.), brewed liquor ( Examples thereof include beer, wine, sake, fruit liquor) and distilled liquor (whiskey, shochu, vodka, etc.). They are,
You may use it in combination of 2 or more type.

The form of the attractant of the present invention is not limited, and it can be used in the form of powder or solid, gel, liquid dissolved in a solvent, or the like, and may be used by spraying. However, in terms of shape retention, it is preferable to make it granular.
In order to form a granular form, for example, the active ingredient and additives may be mixed with cornstarch, wheat flour or the like and granulated. At that time, the amount of the active ingredient is an amount capable of maintaining a granular state, and is about 20 to 40% by weight, although it varies depending on the type of the active ingredient. If the blending amount exceeds the above value, it tends to disintegrate, which causes a problem in storability.

As the solvent in the liquid state, water, organic solvent and the like can be mentioned, and a surfactant and the like can be appropriately used, but the solvent used for preparing the extract of the attractant component is used. Good. Further, the solvent may be made into a kit with the attractant, and they may be mixed at the time of use.

When the attractant is used, the attractant is not particularly limited as to be stored therein. For example, a container having an opening through which the active ingredient is released, a capillary action is used to release the active ingredient. Capable containers, capsules and the like can be used. Such a container contains a solvent (which may have a function of merely supporting the attractant or may have a function of dissolving) for improving the attracting effect when the attractant is used. be able to. Further, when using a fly remover, fly remover, adhesive fly remover, etc., an active ingredient is added to an adhesive substance, for example, a mixture of gum arabic, vinyl chloride emulsion, castor oil, etc. , Synthetic resin plate, plywood, fiber rope, etc.

The attractant of the present invention can be applied to flies such as Drosophila, fleas, fly flies, house flies, blow flies, fruit flies, flesh flies, and flies, and has a particularly high attracting activity against house flies and the like. .

Further, the attractant of the present invention can be contained in a fly insecticide. At that time, the form of the attractant and the insecticide may be a solid form, a gel form (jelly or the like), a liquid form dissolved in a solvent or the like, or may be a spray form. Examples of the solvent include water, organic solvents, and the like, and surfactants and the like are also used as appropriate.

EXAMPLES The present invention will be further described below with reference to test examples, but the present invention is not limited thereto.

(Test-1) Clam extract, onion extract powder, scallop extract powder, egg yolk powder, an equal mixture of clam extract and onion extract powder,
And put meat granules for comparison in 2g petri dish each,
Test room (6 with housefly free)
(Tatami equivalent) and installed side by side. Then, the attraction status (the number of times the fly was attracted) was observed for 3 minutes from 1 minute later.

As a result, an equal amount mixture of clam extract and onion extract powder showed the highest attracting effect, and then onion extract powder, egg yolk powder, clam extract and scallop extract powder had the highest attracting effect in the order of meat granules. Was the least attractive.

(Test-2) Granules as shown in Table 1 and tableting tablets as shown in Table 2 were prepared and the attracting effect was evaluated in the same manner as in Test-1. For comparison, a similar test was conducted on meat granules. Table 3 shows the results with granules (2 trials), and Table 4 shows the results with tableting (4 trials). The "clam granules (tablets) + onion granules (tablets)" in Tables 3 and 4 are obtained by mixing equal amounts of individual clam granules (tablets) and onion granules (tablets).

[0020]

[Table 1]

[0021]

[Table 2]

[0022]

[Table 3]

[0023]

[Table 4]

As is clear from Tables 3 and 4, the incorporation of the clam extract and onion extract powder improves the attracting effect as compared with meat granules.

When the clam granules, the onion granules, the clam tablet and the onion tablet were used alone, there was no difference in the attracting effect depending on the amount of the clam extract or onion extract powder contained in each. .
Furthermore, when the clam extract and the onion extract powder are mixed and used, almost the same attracting effect is obtained regardless of whether they are blended in the same formulation or used as separate formulations.

[0026]

INDUSTRIAL APPLICABILITY The present invention provides at least one of onion, clam, scallop or egg yolk powder, or an extract thereof.
Or a mixture of onion extract and clam extract as an active ingredient, it is possible to maintain a high fly attracting effect in any use situation.
