Abstract

PROBLEM TO BE SOLVED: To obtain a new agent replacing a pyrethroid-based insecticide, causing a flushing out of cockroaches. SOLUTION: This flushing out agent against cockroaches is characterized by comprising one or more kinds selected from a terpene-based aldehyde, an aromatic ring-containing aldehyde, an aromatic ring-containing alcohol, a cyclic ketone, an anthranilic acid ester and phenol as an active ingredient.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a novel cockroach flushing-out agent.

[0002]

2. Description of the Related Art Generally, cockroaches such as cockroaches are sprayed with an aerosol or smoked with a fumigant to control pests lurking in the shadows of the human eye. When a pyrethroid-based insecticide is added to these preparations, it is known that a phenomenon (flashing out) of cockroaches jumping out of the shade is observed. This phenomenon increases the chance that the cockroaches come into contact with the insecticide, thereby increasing the insecticidal effect. Therefore, it is recognized as one of the important actions when controlling cockroaches in kitchen facilities, vending machines, food warehouses, etc. where there are many shades.

On the other hand, when pyrethroid insecticides are frequently used, cockroaches develop resistance, and as a result, sufficient flushing out and insecticidal effects may not be obtained. However, this phenomenon is unique to pyrethroid insecticides, not found in organophosphorus or carbamate insecticides, and no other effective drug is known. Therefore, development of an effective drug instead of a pyrethroid insecticide has been desired.

[0004]

DISCLOSURE OF THE INVENTION The present invention has been made in view of the above situation, and has as its object to provide a novel agent which causes flushing out of cockroaches, which is an alternative to pyrethroid insecticides. It is the purpose.

[0005]

Means for Solving the Problems The present inventors have conducted intensive studies to satisfy the above-mentioned problems, and as a result, have found that certain essential oil components or aroma components cause flushing out of cockroaches. Reached. That is, the present invention comprises the following cockroach flushing-out agent. (1) One or two selected from terpene aldehydes, aldehydes having an aromatic ring, alcohols having an aromatic ring, cyclic ketones, anthranilates and phenols
A flushing-out agent for cockroaches, comprising at least one species as an active ingredient.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION In the present invention, flushing-out active ingredients include terpene aldehydes exemplified by citronellal, hydroxycitronellal, etc .; An aldehyde having an aromatic ring exemplified by); an alcohol having an aromatic ring exemplified by benzyl alcohol, phenylethyl alcohol, phenylpropyl alcohol, phenylbutyl alcohol and the like; a cyclic ketone exemplified by ligstral, jasmon, hedion and the like; Anthranilate esters such as methyl anthranilate and ethyl anthranilate; phenols such as estragole; and these may be used alone or in combination of two or more. Can be used.

Of these, citronellal, cinnamaldehyde, helional, benzyl alcohol, phenylethyl alcohol, phenylpropyl alcohol, estragole, jasmon, and methyl anthranilate are preferred because of their excellent flushing out.

The flushing-out agent for cockroaches of the present invention (hereinafter, also referred to as a flushing-out agent) can be prepared into various preparations by using an appropriate carrier, propellant, additive, etc. It can be used as a spray aerosol, spray, fumigant, fumigation, vaporizer, liquid, emulsion, coating, liquid for absorbent core, etc.
Aerosols, all-injection aerosols, sprays, liquids, and emulsions are preferred because the active ingredient can be used as droplets of an appropriate size and the effect is excellent.

To prepare these preparations, liquid carriers such as water, alcohols, pentanes, paraffins and glycols; solid carriers such as inorganic powders and organic powders; and propellants such as liquefied gas and compressed gas Surfactants, thickeners, antioxidants,
What is necessary is just to prepare using additives, such as a film forming agent.

The content of the active ingredient in the preparation may be 0.1 to 20% by weight, and more preferably 0.5 to 20% by weight, based on the total amount of the preparation.

If necessary, the preparation may contain an insecticide, a bactericidal (antifungal) agent, a fragrance, a deodorant and the like.

The flushing-out agent of the present invention is suitable for fumigation and evaporation in kitchen facilities, food warehouses, and the like, or for spraying into gaps in vending machines and cupboards.

[0013]

EXAMPLES The present invention will be described in more detail with reference to the following Examples, but it should not be construed that the present invention is limited thereto.

Evaluation of flushing out (1) Test method An ethanol solution containing 2.5% of the reagent was prepared,
50 ml thereof was pressurized with air to obtain a spray. And a test box made of plywood (one piece 5cm, height 15cm
, 10 female adult German cockroaches were placed in a triangular prism, one end of which was sealed with a plywood plate, covered with gauze, and secured with a rubber band. After the test box was allowed to stand for 12 hours, the test box was placed vertically in a cylinder having a diameter of 20 cm and a height of 55 cm as schematically shown in FIG. (About 1 g) was sprayed. After spraying, the cylinder was removed, and the number of German cockroaches protruding from the test box over time was counted. As a comparative example, 3
A similar test was carried out using a spray in place of 2.5% of the pyrethroid insecticide.

(2) Test Results The test results are shown in Table 1. The essential oil component or the fragrance component, which is the flushing-out agent of the present invention, was found to jump out 30 seconds after spraying, and was excellent in flushing-out. The effects were all superior to those of the pyrethroid insecticides used in Comparative Examples.

Particularly, citronellal, cinamic aldehyde, helional, benzyl alcohol, phenylethyl alcohol, phenylpropyl alcohol, estragole, jasmon, and methyl anthranilate were excellent in effect.
