Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for exterminating flying pests, the purpose of which is to make the insects lose their ability to fly by attaching an aqueous emulsion of an adhesive composition to their bodies.

Insecticides that have been widely used in the past include toxic chemical substances, and their toxicity is used to exterminate pests.

However, recently, the problem of environmental pollution caused by poisonous substances has been attracting attention, and it goes without saying that less toxic insecticides, preferably completely non-toxic extermination methods, are expected to emerge.

On the other hand, the efficacy of insecticides is a major problem, as even though they are toxic, pests often acquire resistance to the poison through repeated use, resulting in a reduction in their efficacy.

Acquisition of resistance to these drugs is an unavoidable problem as long as poisons are used, and in practice, there are cases in which insecticides are completely ineffective and cannot be used.

Flies in garbage disposal sites in particular have a strong tendency to acquire resistance, and countermeasures have been desired.

Furthermore, a problem unique to garbage disposal sites is that it is difficult to exterminate the larval stage, and adults must be targeted for extermination.

In other words, in modern garbage disposal sites, garbage is often placed in polyethylene bags and then sprayed with insecticides, which prevents the chemicals from penetrating into the garbage and causing pests to enter the garbage. It spends its larval stage and emerges as an adult.

Since insecticides are sprayed on adult insects, the escape rate is high, and strong insects that survive due to insufficient adhesion continue to reproduce, resulting in extremely rapid development of resistance to insecticides. .

In addition to the above-mentioned method of spraying insecticides, it is also possible to use fly paper or fly fly ribbons, but because the control is flat, the extermination efficiency is low, and in garbage disposal sites, the treatment area
It cannot be put to practical use in terms of work efficiency either.

The present invention has been made with attention to these circumstances, and is intended to prevent environmental pollution caused by insecticidal poisons and the acquisition of resistance of insect pests to chemicals by making full use of physical effects, rather than killing insects with insecticides. To provide a method for exterminating flying pests that can effectively exterminate flying pests without worrying about precautions.

The first gist of the method of the present invention, which achieves the above object, is that (4) 10 to 0.5 parts of one or more rubbers selected from polyisobutylene, natural rubber, and synthetic rubber, and (B) polybutene. and/or 90 to 99.5 parts of refined mineral oil, and the second aspect is (4) selected from polyisobutylene, natural rubber, and synthetic rubber. One or more rubbers 10-0.5
and (B) polybutene and/or refined mineral oil 90-99
．． 5 parts of a tackifying resin and (0) an aqueous emulsion of a tackifying composition comprising 50 parts or less of a tackifying resin.

This not only exterminates pests while they are in flight, but also prevents them from escaping when they are in the wings, so this is especially effective when the area to be exterminated covers a wide area, such as a garbage dump or a garbage disposal site.

When spraying the aqueous emulsion of the adhesive composition according to the present invention, the emulsion is diluted with water to the extent that it can be sprayed, and then sprayed in a mist form with a sprayer or the like to physically prevent the emulsion from flying. In this way, flying pests are exterminated three-dimensionally, or the fallen aqueous emulsion forms a sticky film on dirt and traps it.

Therefore, the mode of extermination is completely different from conventional methods of killing insects using poisonous substances.

Such an adhesive composition is composed of (4) and (B) as described above, and when the adhesive is to be strengthened, it is composed of (A), (B) (and (C)). Consisting of

Additionally, an antioxidant such as BHT (di-tert-butyl para-cresol) may be added, and a small amount of an insecticide such as MEP agent (fenitrothion) may be added to aid in the knockdown effect.

Furthermore, an attractant may be added to increase the capture rate of the chemicals after they fall onto the trash.

The polyisobutylene has an average molecular weight of 10.000.
~200.000 preferably 60.000~135.0
00 polyisobutylene, natural rubber with an average molecular weight of 50.000 to i, o o o, o o o preferably 100.000 to 300,000, synthetic rubber such as styrene-butadiene copolymer, etc. Rubbers are exemplified, and furthermore, the above-mentioned rubbers may be latex flashings.

If the content of these rubbers exceeds the above-mentioned ratio, the rubbery properties will become stronger when the adhesive film is formed, the adhesive composition will gel, and the pest capture rate will decrease.

In addition, the rubber may aggregate due to sunlight, etc. and its adhesiveness may decrease.
The viscosity increases and emulsification becomes difficult.

On the other hand, if the ratio is less than the above (in this case, a sufficient adhesive effect cannot be obtained).

The polybutene has an average molecular weight of 500 to 2,650, preferably 1,200 to 2,300, and the refined mineral oil has a viscosity of 150 centimeters or more at 37.8°C.
Preferably it is 400 to 600 centistokes.

The blending amount of polybutene and/or refined mineral oil may be determined so that the blending ratio of the above-mentioned rubbers is appropriate.

Furthermore, tackifying resins include rosin, hydrogenated rosin, hydrogenated rosin ester, hydrogenated petroleum resin, aliphatic hydrocarbon resin, terpene hydrocarbon resin, alicyclic hydrocarbon resin, aromatic hydrocarbon resin, etc. Preferred are hydrogenated rosin, hydrogenated rosin ester, and hydrogenated petroleum resin.

If the amount of the tackifying resin exceeds the above ratio, the adhesive becomes hard and becomes a barking state where pests such as flies can walk on the adhesive, which is not suitable.

Next, method of the present invention) To produce the aqueous emulsion used, any method may be used, but it is preferable to emulsify the adhesive composition by the method shown below.

That is, first, divide the entire desired amount of polybutene and/or refined mineral oil into two, and (a) take 10 to 20 parts of it and dissolve 0.5 to 10 parts, which is the total amount of rubber (formation of comb melt). ).

Separately, (b) 50 parts or less of a tackifier resin is blended into the remainder of the polybutene and/or refined mineral oil by packaging, and an emulsifier (
- e.g. polyethylene glycol monooleate) 5-0
．． 5 parts and 20 to 89.5 parts of water to prepare an aqueous emulsion.

Next, the aqueous emulsion (b) is gradually added to the rubber melt (a) with stirring to obtain a uniform aqueous emulsion.

This is mixed with water in the desired proportions, preferably an aqueous emulsion.
It may be used by diluting it with 300 parts or less of water per 00 parts.

For example, simply mixing polybutene and rubber emulsions without producing an aqueous emulsion in the manner described above is not recommended because the emulsions will fall on the garbage heap and will not form a sticky film after the water evaporates.

The reason for this is that the colloidal particles of polybutene and rubber are simply dispersed in water, and even though the polybutene becomes a continuous layer after water evaporates, the rubber is only dispersed as colloidal particles in the polybutene layer. Does not become adhesive.

In other words, it is presumed that the ignition state is simply a mixture of polybutene and fine powdered rubber at room temperature.

To actually carry out the method of the present invention, it is only necessary to spray the aqueous emulsion suitably diluted with water onto the pests flying onto the garbage heap using a powered or manual sprayer, and instantly kill the flying pests. Capture and drop.

After being sprayed and exterminated, all you have to do is leave it as is, and the fallen emulsion will cover the surface of the garbage and form an adhesive film that is resistant to weather (rainfall, light), and will be able to capture pests that fly and take wing after being sprayed. , - The effect of killing two birds with one stone is expected.

According to the method of the present invention, the following various effects can be obtained.

That is, since it is a physical extermination method, there is no environmental pollution caused by poisonous substances, and there is no risk of the emergence of poisonous pests.

■It is also expected to be effective in exterminating insects in areas where insect pests have acquired resistance and spraying insecticides is ineffective.

■Since it is an emulsion that does not use low flammable organic solvents, there is no risk of fire or poisoning from organic solvents.

(2) The organic concentration of the adhesive composition can be adjusted with water depending on the application, it can be easily sprayed with a commercially available sprayer or sprayer, and it is odorless, which is extremely advantageous in terms of work.

■Special ingenuity has been applied to the formulation and manufacturing method, so it does not re-emulsify and run off even in the rain, and is weather resistant without curing and deterioration due to sunlight or ultraviolet rays.

Next, the method of the present invention will be explained by way of examples.
