Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a pest control agent, and more particularly to a pest control agent for collective organisms such as ants.

[0002]

2. Description of the Related Art Pest control agents conventionally used for controlling pests, particularly ants and the like, include food poisons and aerosols, which are attractants mainly composed of pest control agents.
After being mixed with other fillers, binders, etc., they are molded into a dosage form such as powder, granules, etc., and are used by being placed at or near the place to be exterminated. Further, the aerosol agent is used by dissolving the insecticidal component in a solvent or the like and filling it together with the propellant. The present applicant has previously proposed a method of killing all ants existing in burrows by using a poison bait containing a fast-acting insecticide and a coagulant bait containing the above-mentioned attractant, extender, slow-acting insecticide, etc. .

[0003]

If the insecticide is sprayed in a liquid state, it is highly possible that the insects can be directly treated to ants or the like near the entrance of the burrow, but depending on the shape of the burrow, the place where the burrowing occurs, etc. In some cases, it is impossible or incomplete to reach the insects with the drug. The present invention is to provide a pest control agent which greatly expands the controllable environment in any environment where organisms to be controlled are present and is easy to administer a pest control agent and has a high pest control effect. .

[0004]

The present invention is an ant control agent which is characterized by containing a fast-acting pyrethroid drug such as syringa extract or one of a slow-acting pyrethroid drug as an active ingredient. The above-mentioned problems can be solved by this.

The alarm pheromone or its similar active substance that can be used in the present invention (hereinafter, alarm pheromone or its similar active substance is generically referred to as alarm pheromone) is secreted by organisms such as ants and termites to be controlled. The present invention is not limited to the alarm pheromones described above, but includes a synthetic product thereof, or any natural compound or artificial synthetic compound that is not secreted by the organism but has an action equivalent to that. The alarm pheromone of the present invention may have not only the activity of the alarm pheromone itself but also the action of inducing the secretion of the alarm pheromone in an organism. Alternatively, the present invention can include any agent that induces secretion of the alarm pheromone. In this case, the part of the secretory gland that secretes the alarm pheromone, the gland type and the like are not particularly limited, and examples thereof include the large chin gland, the anal gland, the venom gland, and the Dufoy gland in the ant family. Further, in the present invention,
One or more alarm pheromones can be appropriately selected according to the target species, and one or more alarm pheromones effective for a plurality of species can be selected and used.

Examples of the alarm pheromone include low molecular weight organic compounds such as esters, ketones,
Alcohols, aldehydes, organic acids, hydrocarbons,
Examples thereof include heterocycles, and the molecular weight is usually selected from the range of 100 to 200. Examples of the specific compound include butyl acetate, decyl acetate, 6

Examples include propyl or ethylpyrazine.

The pest control agent of the present invention, even if the alarm pheromone is mixed with the pest control agent in advance and used, a pest control agent containing the alarm pheromone and a pest control agent containing the alarm pheromone are separately produced into a kit. The above may be used, and both can be mixed and processed at the time of use. The alarm pheromone may be used as it is or diluted with various solvents. The amount of the alarm pheromone used in the pest control agent of the present invention varies depending on the target species, but is 0.05 to 3% by weight, preferably 0.1 to 0.
It is selected from the range of 5% by weight. The pest control agent can be formulated into any form. Examples of the formulation include liquid, solid (eg, granular, powder, granular, lump, etc.), gel,

It is selected from the range of 100 parts by weight.

[0012]

In the present invention, since the alarm pheromone is used, the ants and the like existing in the vicinity of the pest control agent are usually gathered in one place, but if the voluntary alarm pheromone is received, the behavior pattern is broken. It causes turbulent behavior, increases movement, increases the probability of contact with a pest control agent, and eventually enhances the pest control effect.

[0013]

EXAMPLES Hereinafter, specific examples of the present invention will be described.
The present invention is not limited to this. Experimental Example 1 The results of qualitatively examining the activity of the alarm pheromone stock solution against various ants are shown below. Types of alarm pheromones Types of ants Dwarf ants Whale ants Amime ants Amey ants Butyl acetate ○ ○ ○ ○ n-Undecane △ ○ △ △ 2-Heptanone ○ ○ ○ ○ Ethyl isobutyl ketone ○ ○ ○ ○ 3-Octanone ○ ○ ○ ○ ○: Clear movement Reaction △: Slight transfer reaction

Experimental Example 2 The activity was investigated in the same manner as in Experimental Example 1 above, except that the concentration of the butyl acetate aqueous solution as the alarm pheromone was changed. Concentration Red-tailed ant Wrinkle ant White-tailed ant Ameyroant 1% ○ ○ ○ ○ 0.2% ○ ○ ○ ○ 0.1% △ △ △ △ ○: Clear transfer reaction △: Slightly diffusive transfer reaction

Example 1 Using 0.435 g of allethrin as an insecticide, 0.160 g of neopinamine forte and 1.02 g of S-421, mixed insecticide and 0 of butyl acetate of alarm pheromone dissolved in 100 ml of 0.1% Tween 20 were used. The insect pest control agent of the present invention was prepared from 100 g of an alarm pheromone solution prepared by dissolving 0.5 g of Tween 20 in 0.1%.
Butyl acetate is an active substance similar to the secretory alarm pheromone.

Experimental Example 3 The performance of the pest control agent prepared in Example 1 was tested and evaluated under the following conditions. Polyethylene cup (diameter 11.6c
Quartz sand was thinly laid on the bottom of the m (height, 6 cm) and water was appropriately added dropwise. 100 of them were released and used for the test after 3 days. Two holes were punched in the polyethylene cup lid before treatment. On the other hand, 0.5 ml of the mixed insecticide was dropped on the bottom of the cup with a dropper to a length of 4 cm, and then the water or alarm pheromone solution of 0.5 m was added to the control section through another hole.
1 was added dropwise to observe the behavior of the short-necked ants. In addition, the number of ants that died after touching the insecticide due to the migration of ants was counted (see Table 1). Alarm pheromone behavior after treatment of Amemari ant before treatment 2-3 after treatment
The results observed at the minute, 15 minutes after the treatment, and 30 minutes after the treatment are shown in FIG. Before the treatment, the squirrel 1 had formed a group, but when the alarm pheromone solution 2 was treated, it became 2-3.
After a few minutes, the spider pups were dispersed so as to disperse, and a large number of Amemeari started turning around the edge of the polyethylene cup 3 and mixed insecticide 4
Contact with the drug where it was treated with. After about 20 minutes, they started to form a group again, and after 30 minutes, they became a lump.

On the other hand, in the water treatment of the control group, migration of the ants was not observed. It was considered that the migration of the pearl oysters by the treatment with the alarm pheromone solution was larger than expected, and as a result, the frequency of contact with the insecticide was also increased, and about 60% of the lethality was observed 3 hours after the treatment. On the other hand, in the water of the control area, migration was not observed in the water, so no control effect was observed (see Table 1).
From the above results, the treatment with the alarm pheromone solution facilitated the movement of ants, and consequently, made it easier for the ants to come into contact with the drug, thus enhancing the control effect.

[Table 1]

Example 2 The mixed insecticide of Example 1 and the alarm pheromone solution were mixed to prepare a pest control agent.

Experimental Example 4 Experimental Example 3 was repeated, except that the mixed pesticide was treated with the same amount of the insect pest control agent of the present invention or a comparative product obtained by removing the alarm pheromone solution from the present invention. The efficacy of each treatment agent was evaluated under the same conditions as in Table 2, and the results are shown in Table 2.
