Abstract

PURPOSE:To establish a technique of preventing flies from flying in a livestock industrial farm. CONSTITUTION:A fibrous material such as victoria lawn (cotton or hemp) is immersed in a solution containing an insecticide such as permethrin or diazinon dissolved therein, then removed from the immersion and dried to provide fibers 14, 16, 18 and 20 for preventing flies from flying. The resultant fibers have high fast acting properties of knockdown effects. When they are installed in a place where the flies come flying such as livestock excreta or a barn of a livestock industrial farm household, the flight of the flies is remarkably reduced without visually exercising a negative image and the exposure dose of the livestock or operators to the insecticide is remarkably reduced. Furthermore, this method is simultaneously effective in saving labor and resources and economical. The plural fibers for preventing the flies from flying produced by using different kinds of insecticides can be installed to avoid the problems in chemical resistance of the flies and surely knock down the flies.

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a fly flight prevention fiber used for controlling flies in a fly source such as livestock excrement in livestock farms and in places such as livestock houses where flies fly at high density, and More particularly, it relates to a fly flight preventing method using the fiber, and more specifically, a fly flight preventing fiber having a high concentration of an insecticide attached to the surface of the fiber, and a fly flight preventing fiber having various shapes and insecticide compositions. By installing it at the fly source or fly fly location, it is possible to quickly and labor-savingly control flies, avoid pesticide resistance problems, and prevent visual aversion. A method for preventing flight.

[0002]

2. Description of the Related Art Since flies are a non-hygienic pest and a transmission medium for various pathogens, flies are felt in the house as they fly and are caught on dishes, which makes them feel unclean and makes their daily lives uncomfortable. It is hated for hygiene.

For this reason, flies are controlled so that the flies do not invade and fly into the living environment such as a house, and a wide variety of tools and agents have been developed and provided for this purpose.

On the other hand, excrements of organisms such as manure that occupy more than half of industrial wastes and general wastes become a source of flies or a high-density landing place of flies, and as long as the organisms survive, they are excreted. Things are destined to exist, so
In terms of daily life, they live together with a fly source or a high density fly landing place.

[0006] These are serious problems for livestock farmers who are engaged in raising livestock, and a huge amount of manure excreted by livestock is being established as a soil reduction technique by drying or composting. However, there are unsolved parts in terms of early treatment and cost, and for this reason manure is often left as excreted at the livestock site, which is the source of flies or a high density fly landing place. It is not uncommon for flies to gather near livestock to be reared, hindering the habitability of the livestock themselves and increasing stress on the livestock themselves, resulting in reduced productivity. Since the work is carried out in a flock, it causes discomfort, resulting in a decrease in work efficiency and a decrease in the working population of livestock farmers.

[0006] In recent years, the scene where livestock farms and ordinary houses are adjacent to each other is not uncommon, and this tendency of mixed living is progressing more and more. In this situation, livestock farms are flying into ordinary houses. As flies impair the living environment hygiene, complaints from livestock farmers to livestock farmers frequently occur, and with the increasing need for fly control at livestock farmers,
There is a demand for sophistication.

[0007] Among them, in livestock farms, flies have been controlled using the tools and means described below.

Physical trapping was performed by suspending a fly ribbon or a trap containing a fly attractant coated with a sticky substance on the eaves of a livestock shed or the like, or by installing the trap near a fly source.

By spraying the insecticide directly to the flies flying in the barn or the like, or by spraying and attaching it to the walls or columns of the barn or the like so that the insecticidal active ingredient touches the flies. Flies were killed using the biochemical effects of insecticides.

[0010] Further, research on animal husbandry, which is an academic document, Vol. 45, No. 11, page 1271 (1991), Vol. 45, No. 12
No. 1397 (1991), Vol. 46, No. 8, 881
Page (1992) discloses that a plastic net containing an insecticide is effective for controlling flies in livestock farmers.

[0011]

However, the conventional fly control tool and fly control method described above have various problems as described below.

[0012] That is, the physical capture by fly ribbons or traps does not last long because the catching is limited. Therefore, especially at the peak of flies, frequent exchange of fly ribbons and traps with a large number of flies is required. There is a problem in that it causes an inconvenient and visually unsanitary and unclean feeling, which promotes the aversion of general dwellers to livestock houses.

The method of spraying an insecticide is effective for flies that have already fly or stayed in a livestock shed or in the vicinity of excrement, but many flies escape during spraying of the insecticide. It is less effective against flies that have entered after spraying,
The amount of pesticide that adheres to walls and pillars is also very small, and it is transient and does not have persistence (residual effect), so frequent pesticide spraying is performed each time a new fly or invasion occurs. However, there is a problem in that the work requires the use of a large amount of the insecticide and cannot meet the demand for resource saving, and the adjustment of the spray liquid is troublesome and inconvenient.

Further, in the method of spraying an insecticide,
When sprayed in a livestock shed, the insecticide will adhere to the livestock in the livestock shed, so that the use of the insecticide for indoor use is restricted, and the insecticide is orally or transdermally introduced into the body of the livestock. Ingestion amount and irritation amount to mucous membrane of eyes of the livestock are inevitably large, and there is a big possibility that the health of the livestock is deteriorated and the commercial value is lowered. Because it is a spray in a semi-open space,
There is a problem that the inhaled amount of the insecticide and the irritation to the mucous membranes of the eyes and the like are great and there is a great risk of damaging the health.

Further, when a fly having a large resistance to an insecticide is flying, the spray amount of the insecticide is increased, so that the above-mentioned problem is particularly remarkable. A large amount of spray increases the resistance of the flies to insecticides, which may become a base for the emergence of flies that are highly resistant to insecticides such as Yumenoshima, and to prevent the flies from acquiring resistance. There is a problem that pesticide management such as intermittently mixing a plurality of different series pesticides is very troublesome.

Since the plastic net in which the insecticide is kneaded lacks quick-acting effect as described in the above-mentioned document, flies penetrate into general houses from the fly generation source such as excrement yard or livestock house, or the fly-crowded place. The rate of establishment is still high, and the insecticidal effect is extremely reduced after more than one year. Therefore, it requires replacement with a new plastic net, resulting in high cost and not contributing to resource saving requests. In order to further improve the environmental hygiene of the living environment, it has been hoped that the application of rapid effect, cost reduction and resource saving will be put to practical use.

The present invention has been made in view of the above circumstances, and enables fast-acting, sustained, labor-saving, and healthy fly control, and avoids the problem of insecticide resistance and provides a visual dislike. It is intended to provide a fly flight preventing fiber and a fly flight preventing method that can be held.

[0018]

In order to achieve the above object, the present invention provides a fly flight preventing fiber characterized in that a fiber material is dipped in a solution in which an insecticide is dissolved, de-immersed and then dried. It is provided.

Further, the present invention solves the above-mentioned problems by providing a fly flight preventing method characterized in that the fly flight preventing fiber is installed in the vicinity of a fly generating source or a fly flying place. .

Further, the present invention solves the above problems by providing a fly flight preventing method characterized in that two or more kinds of the fly flight preventing fibers produced by using different insecticides are installed. It is a thing.

[0021]

By removing the solvent of the solution in which the insecticide is dissolved by drying, the insecticidal drug substance adheres to the fly flight preventing fiber according to the present invention.

When a fly stops on a fly flight preventing fiber installed near the fly generation source or near the fly flight location, the fly flies by touching the pesticide active ingredient and knocks down by poisoning.

When two or more kinds of fly flight preventing fibers produced by using different insecticides are installed, even if the fly has resistance to one insecticide among different insecticides,
Knock down by licking another pesticide ingredient.

[0024]

EXAMPLES Hereinafter, the fly flight preventing fiber and the fly flight preventing method according to the present invention will be described more specifically based on examples.

First, as for the fly flight preventing fiber in this embodiment, as shown in the process diagram of FIG. 2, a solvent and an insecticide are added to a mixer and mixed and stirred, and the fiber material is immersed in this solution, It is manufactured by deimmersing the fiber material and drying it.

The insecticide used may be used as it is as a drug substance (solid or liquid), but it may be diluted with a solvent or a solid diluent and contains auxiliary components such as a surfactant, a synergist and a fly adult attractant. Formulated insecticides may be used.

As the active ingredient of the insecticide, various insecticides can be used as long as they show an insecticidal effect and a knockdown effect on flies, and examples thereof include organophosphorus insecticides such as malathion, diazinon, fenitrothion, chlorpyrifos and acephate. Agents, carbamate insecticides such as dimethoate, BPMC (bassa), XMC (magvar), MPMC (meoval), MTMC (tsumaside), pyrethroid insecticides such as permethrin, allethrin, resmethrin, fenvalerate and trebon, rotenones , Insecticides such as nicotine and padan can be used, but the use of pesticides is prohibited in Japan.
Organochlorine insecticides such as DT, BHC, aldrin, dieldrin, and endrin, and parathion (organophosphorus insecticide) can also be used.

The solvent is a solvent in which the active ingredient of the insecticide used is dissolved, or a suitable surfactant such as a polyoxyethylene nonionic surfactant or an alkylaryl sulfonate is used to homogenize the active ingredient of the insecticide. As long as it is dispersible in a solvent, for example, if it is a fat-soluble one such as malathion, diazinon, trebon, permethrin or DDT, an organic solvent such as toluene, xylene, acetone, benzene or ethyl acetate is used. It is possible to use water and alcohols as a solvent as long as they are water-soluble such as acephate.

Various auxiliary components can be dissolved or dispersed in the solvent. For example, when a pyrethroid insecticide such as permethrin, allethrin, resmethrin, fenvalerate, and trebon is used, sesamin or a synergist can be used. It is also possible to dissolve piperonyl butoxide and the like to enhance the insecticidal effect, and it is also possible to dissolve a fly adult attractant.

Mixing and stirring of the insecticide and the solvent may be carried out to such an extent that they can be uniformly dissolved or dispersed. If a commercially available granule, powder or wettable powder is used as the insecticide, the insecticide Talc used in the formulation, kaolin, bentonite, diatomaceous earth solid diluent such as active ingredient is removed from the adsorbent and dissolved or dispersed in a solvent,
If necessary, heat may be applied to the extent that the insecticidal active ingredient does not chemically decompose.

The fiber material may be any material as long as it can support an insecticidal active ingredient, including natural fiber materials such as cotton, hemp, wool and silk, as well as polyester, nylon, viscose rayon, acetate, acrylic, Synthetic fibers such as polyethylene and polyvinyl chloride can also be used, but by twisting these fiber materials, the area of attachment of the active ingredient of the insecticide per unit weight is increased and it is attached by moisture such as rain. It is desirable to prevent the insecticidal active ingredient from flowing out, and further to prevent chemical alteration / inactivation of the insecticidal active ingredient due to ultraviolet rays or the like.

The shape of the fiber material may be a band cloth shape or a net shape, and may be a shape suitable for the place where the fly flight preventing fiber is installed and the purpose. For example, if it is installed around the column 22 of a livestock shed, a strip of cloth such as cheesecloth can be used, and it can be installed on the side of the livestock shed so that the livestock in the livestock can be seen and the ventilation of the livestock is ensured. For example, it is possible to use a net-like thing that allows the line of sight.

Immersion of the fiber material may be carried out by impregnating the fiber material with the insecticidal active ingredient dissolved or dispersed in a solvent, and in order to avoid uneven impregnation due to generation of bubbles or the like, the fiber material is mixed in the mixer. It is desirable to stir or corrugate the material so that it is impregnated as evenly as possible.

It is desirable to remove solid diluents such as talc, kaolin, bentonite and diatomaceous earth from the mixer before the dipping step.

The content of the pesticidal active ingredient carried on the fiber material varies depending on the physical and chemical properties of the fibrous material and the pesticidal active ingredient, but is about 1% by weight at the maximum and usually 0.5% by weight. % Or less.

Therefore, the ratio of the fiber material to the insecticidal active ingredient and the amount of the solvent are from 2 to 3% by weight or less based on the fiber material from the economical point of view of saving resources and waste. It is desirable to use the solvent to such an extent that the fiber material is completely immersed.

De-immersion is carried out by lifting the fiber material from the mixer, and drying is carried out by air drying or mechanical drying (a temperature of 40 ° C. or lower is desirable) after the liquid does not drip on the surface of the solvent. .

Next, a production example of the fly flight preventing fiber will be shown.

Production Example 1 Toluene 30 kg and permethrin drug substance 600 were added to a mixer.
g was added and well mixed by stirring, and when a uniform solution was formed, 10 kg of net-shaped plastic fibers were dipped and stirred until bubbles were not generated.

The fly flight-preventing fibers obtained in the above Production Examples 1 to 5, and the livestock research as a conventional example, Vol. 45, No. 1
271 (1991), Vol. 45, No. 12, 1397.
Page (1991), Vol. 46, No. 8, page 881 (199).
Knockdown rate of the plastic net described in (2 years) (concentration of pesticide kneading 0.4%, after 30 days of indoor exposure) against adult housefly, ie, transparent cube (50 cm on each side) by the test method described in the same document. ) Housefly (20)
Then, the test results shown in Table 1 were obtained.

[0050]

[Table 1]

That is, the fly flight preventing fiber obtained in Production Example 1 knocks down all of the house flies within three minutes of contact, making them impossible to fly, whereas the plastic net described in the same document Only 60 minutes after contact, 4 animals (20% of the number of house flies tested) were knocked down.

The fly flight preventing fibers obtained in the other production examples 2 to 5 also showed the same knockdown rate as in the production example 1, and knocked down within 3 to 5 minutes after contact.

This shows that the fly-flying prevention fiber according to the present invention is excellent in quick-acting property, and this result can be explained from the motivation for the inventor to complete the present invention.

That is, the present inventor studied the behavior of the housefly in detail by taking a microscopic photograph of the vicinity of the mouth of the housefly, and as a result, the vicinity of the mouth of the housefly was not a sucker shape but a file shape. Ingesting licking by scratching and scraping food etc. using () (thus, the housefly prefers the hard one rather than the watery one), and since it was found that the housefly makes this licking all the time, This is because it is thought that if the insecticidal active ingredient is attached directly to the fiber, the rapid effect will be enhanced.

Therefore, the fly flight preventing fiber according to the present invention has the insecticidal active ingredient directly supported on the fiber material. Therefore, when the fly stops on the fiber material, the fly removes the fiber material with a file near the mouth. It is thought that by cutting without rest, a sufficient amount to cause knockdown is immediately ingested by food poisoning.

According to the research conducted by the present inventor, the fly flight preventing fiber obtained in Production Example 1 seems to be ingested by licking in an amount necessary for knockdown if the fly cuts about 20 times.

On the other hand, in the plastic net described in the above-mentioned literature used in Comparative Example, permethrin clathrated by cyclodextrin was kneaded into the plastic, and the insecticidal active ingredient present on the plastic surface was small. Even if it is ingested, it is ingested as a cyclodextrin clathrate, so it is considered that the contact toxic side rather than the food poisoning side acts strongly, and it takes time for the knockdown effect to appear.

The fly flight-preventing fibers obtained in Production Examples 1 to 5 exhibit a continuous insecticidal effect. However, when the fly flight-preventing effect decreases due to long-term field exposure, etc., the fibers are immersed again in a solution containing an insecticide. By performing the treatment of de-immersion, and then drying, the fly flight-preventing fiber having a rapid effect can be regenerated by repeatedly using the same fiber material, and the request for resource saving and economic efficiency can be answered.

Further, since the treatment process is not difficult and is a simple operation that can be performed by an amateur, a livestock farmer who does not have a specialized technique can easily perform the production and retreatment.

Further, when a fly attractant is attached to the fly flight preventing fiber, if the attractant has a large difference in attracting ability to males and females, the proportion of males and females of the fly fluctuates greatly, which causes reproduction of the fly. The number of flies generated can be remarkably reduced, and the number of flies flying in the barn can be reduced across generations of flies.

The results of investigating the mortality of the housefly with and without the inclusion of a fly attractant are shown in FIGS. 3 and 4. This investigation was conducted with the fly flight preventing fiber (30 cm × 30 c) of Production Example 1.
m) and a fly flight preventing fiber (30 cm × 30 cm) produced in the same manner as in Production Example 1 except that a fly attractant was mixed.
Was installed in a barn and the number of flies that had died 24 hours later and had fallen to the ground and the proportion of males and females were investigated.
This test was conducted 9 times from October to November using the same fly flight preventing fiber as the first time.

Next, a fly flight prevention method for installing the fly flight prevention fibers obtained in Production Examples 1 to 5 near the fly generation source or near the fly flight location will be described using a livestock farm as an example.

The fly flight preventing fiber may be installed at a position where the fly gathering near the fly generating source or the fly flying place stops, and the probability that the fly will fly within 2 m from the ground or floor surface. Can be carried out by various methods considering that the net is very high. For example, in the case of a net-like thing, the net is fixed to a frame like a screen door of a general house, and the net with the frame is used for a livestock house. The manure can be kept in a place where many flies gather, or can be kept so as to surround the manure of livestock so that the manure cannot be seen from the outside.

If it is a cloth-like material such as Chinese sardine cloth, it can be installed by being wound around the column 22 of the livestock shed or hanging from the eaves of the livestock shed.

Depending on the biological / physical properties of the insecticide attached to the fly flight prevention fiber, it is necessary to set the installation location in consideration of the effects on human livestock and the environment.
If the insecticide has relatively large acute and chronic toxicity to mammals and birds, it is desirable to install it in a position where livestock and birds do not come in contact with or lick it. In the case of an insecticide with a very low chronic toxicity, it is possible to put it on a part of the body of the livestock that fly flies in high density, and in the case of a highly water-soluble insecticide, It is desirable for environmental hygiene to install it in a place where it will not be washed away by rain and mixed into the water supply.

When the net-like plastic fiber obtained in Production Example 1 is installed on the open side surface of the barn 10 or Production Example 2
When the fly flight prevention fibers obtained in ~ 5 are installed in the pillars 22 of the cowshed 10, there is no visual negative image unlike the fly ribbon and the like. The result was that it did not spoil sanitary feelings, and because of its rapid insecticidal effect, the number of flies that invaded neighboring houses was drastically reduced, further improving the hygiene of the living environment.

Further, since the insecticidal effect is not transient, but the rapid effect is sustained, the labor such as frequent replacement of the fly flight preventing fibers installed is eliminated, and the amount of insecticide used is relatively reduced. This contributes to resource saving and economic efficiency, and since there is no stimulation of insecticides on the mucous membranes of livestock eyes, the number of flies that attach to the livestock themselves or fly around the livestock is drastically reduced, reducing livestock stress. The workability of livestock workers is improved by improving the productivity and product value of healthy livestock and improving the working environment (such as drastically reducing the amount of exposure to pesticides and eliminating the feeling of uncleanness due to the drastic reduction of flies in the workplace). Efficiency improvements have also been achieved.

Next, the fly flight preventing fibers obtained in Production Examples 2 to 4 carry an organophosphorus insecticide, a pyrethroid insecticide, and a carbamate insecticide, respectively, but they have different functions. When the fly flight preventing fibers carrying the insecticide are installed adjacent to each other in the barn 10,
For example, if a fly has a high resistance to organophosphorus insecticides, the pyrethroid insecticides and carbamate insecticides in the vicinity are supported without licking the fly flight preventing fibers of Production Example 2 and knocking them down. When the fly flight preventing fibers of Production Examples 3 to 4 are licked, knocking down occurs, and even a fly having resistance to a specific insecticide can surely knock down.

Therefore, the pesticide resistance problem can be solved without being bothered by the management problem of spraying the pesticide, which restricts the continuous use of the same drug in order to avoid the acquisition of fly resistance. .

Further, the problem of insecticide resistance can also be solved by installing a material carrying a plurality of different series insecticides such as the fly flight preventing fiber of Production Example 5. In this case, In addition, the insecticidal effect on resistant flies is improved rapidly, and the labor and management problems associated with installing several types (such as which fiber has which series of insecticide attached) can be further eliminated. Become.

Although the present invention has been described based on the embodiments, the present invention is not limited to these.

For example, the fly flight preventing fiber is not limited to use in a livestock farm, but can be installed in a place such as a raw garbage storage area or a night soil treatment layer where flies are likely to occur and fly. , Its application range is wide.

Further, it can be used not only for flies but also for flight prevention / killing of various non-hygienic pests such as mosquitoes, fleas and mites.
