Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a repellent such as a cockroach used in a storage cabinet under a kitchen sink where a cockroach easily appears and disappears, a cupboard, and a mat for repelling a cockroach impregnated with the mat. is there.

[0002]

2. Description of the Related Art As a conventional method for controlling various sanitary pests such as cockroaches, a method of spraying a pyrethroid insecticide or a method of catching it with an insect trap is known.

Although these methods are capable of eradicating harmful insects by killing or trapping insects or preventing damages such as food damage and blood sucking caused by insects to some extent, they can be used as storage cabinets under a kitchen sink, cupboards, and mizuya. However, it is not possible to avoid the infestation of pests in furniture such as a chest of drawers or to the human body, contamination of invasion, etc., and it is not possible to exert a sufficient exterminating effect.

In addition, the above method requires the treatment of insect pests after insecticidal or trapping, which makes it difficult to dispose of insect pests that die after invading furniture and the like, and has a harmful effect of becoming a pollution source.

On the other hand, as a method for preventing the above-mentioned pests from flying and invading, a method is known in which the repellent odor of a pest repellent is applied and the repellent is applied to the skin or underwear, and various repellents used in these methods are known. The substance has been proposed for research and development. For example, several kinds of substances including N, N-diethyl-meta-toluamide are used as repellents against blood-sucking pests such as mosquitoes, mites and fleas in the form of spray, lotion and cream. ing.

[0006] The above method did not provide a sufficient repellent effect against sanitary pests such as cockroaches, stored-grain pests such as weevil and insects such as ants, and their invasion could not be reliably prevented. .

The present invention has been made to overcome the above-mentioned problems, and exhibits an excellent repellent effect against sanitary pests such as cockroaches, stored-grain pests such as weevil and insects such as ants. It is intended to provide a repellent agent for cockroaches and a repellent mat for cockroaches that can reliably prevent invasion.

[0008]

The present invention is a repellent such as a cockroach characterized by containing 2-undecanone (methyl N-nonyl ketone) as an active ingredient.

Also, 2-undecanone containing either or both of thymol and orthophenylphenol as an active ingredient, or 2-undecanone containing either thymol or orthophenylphenol. Alternatively, the present invention relates to a repellent mat such as a cockroach in which both of them are contained as active ingredients and a fragrance is added to the mat, and the mat is impregnated with these repellents.

The repellent of the present invention can exhibit extremely excellent pest repellent effect based on the fact that it contains 2-undecanone. The repellent effect has a strong repellent effect against sanitary pests such as cockroaches, stored-grain pests such as Coccinella japonica and Weevil, and insects such as ants and termites.

Therefore, the repellent of the present invention is sure to prevent hygiene pests such as cockroaches and storage pests from coming into storages under kitchen sinks, cupboards, food storages, etc. To prevent insects from habiting, eating,
Blood feeding and contamination can be avoided.

Furthermore, the repellent for cockroaches of the present invention can be applied as it is to the place where the above-mentioned active ingredient is required to repel cockroaches, etc., and to this, timole or orthophenylphenol is used as one or both. By adding both to add antibacterial effect and adding a fragrance, the chemical odor of timoles and orthophenylphenols can be masked, and by adding a fragrance, it is possible to change from high volatility to low volatility. The transpiration of the active ingredient can be controlled.

Further, by impregnating a pulp mat with the repellent such as a cockroach of the present invention and using it, the repellent effect can be more stably maintained for a long period of time.

[0014]

BEST MODE FOR CARRYING OUT THE INVENTION The purpose of use of each repellent in the present invention will be explained below. 2-Undecanone (methyl n-nonyl)
Luketone) has a cockroach repellent effect, and timoles and orthophenylphenols have antibacterial effects. To mask these drugs or as a transpiration regulator, fragrances such as orange oil, rose oil, perilla oil Etc., impregnate this into a pulp mat, put it in a storage container with a ventilation hole, and use it by attaching it to the wall of a kitchen cabinet, food cabinet, etc. .

Furthermore, it is placed in an area for invading stored-grain pests such as weevil to reliably prevent the incoming, approach, contact and invasion of stored-grain pests, as well as habitation, feeding damage and pollution of insects such as ants and termites in a specific area. Can be avoided.

The application amount of the repellent for cockroaches of the present invention may be appropriately determined according to the application method and the application site, and is not limited, but usually 10 to 100% by weight of the active ingredient, for example, 2-undecanone. A repellent such as a cockroach containing 60%, 15% Timol, 15 orthophenylphenol, and 10% perilla oil was impregnated in a pulp mat of 70 × 70 × 2.8 mm in an amount of about 5 g. , Put it in a mat storage container with ventilation holes on the top surface, and use the adhesive sheet on the back surface of the storage container, for example, by sticking it to the wall of the storage under the sink in the kitchen and using it, the result is about 90% cockroach repellent effect Was maintained for 30 days, and the antibacterial effect was also effective.

(Test method) The untreated section has a length of 80, a width of 70,
A 40 cm tall acrylic box was prepared, and a box of the same shape was prepared for the treatment area. Inside each box was a shelter made from cardboard, solid feed, and sugar water. I chose to put it in the box.

A passage is provided between these two boxes so that cockroaches can freely move in and out, and a wire mesh is used to prevent gas from accumulating in the passage. One of the two boxes is treated and the other is untreated. And put the chemicals on the ceiling of the box in the treatment area,
The box was left overnight so as to be filled with the drug, and then the cockroaches were released to the untreated section, and it was observed whether or not the cockroaches moved to the treated section.

For the test weevil, weevils, rice grains and grains were placed in the box, and for the ant test ants, sugar was placed in the box. Each of the 40 test worms was tested by the same test method. Observed to move to the box.

No. 1 to No. 8 were made by impregnating a pulp mat with a repellent, and in an aluminum sheet having a hole of 20 × 24 mm, adult German cockroaches, male and female, 10 each.
20 animals were put in total.
