Description

METHOD FOR THE CONTROL OF ARTHROPODS DESCRIPTION OF THE INVENTION The present invention relates to a new method for controlling harmful arthropods in the control of private and professional pests, in particular in agriculture, in the protection of stored products, in the protection of materials, in the control of vectors , in the house and garden and also in forests. Control in particular of arthropods that live inside or outside of public or private facilities, such as apartments, houses, hospitals, food processing companies, large kitchens, restaurants and other private or public facilities is of great importance from a point of view hygienic. In the areas described, the arthropods are controlled in most cases by atomizers. Here, a formulation containing highly concentrated insecticide is diluted with water and sprayed as an aqueous spray liquor of 25 to 100 / m2 onto the surfaces in which the arthropods to be controlled move. Arthropods are killed by contact with the insecticide coating. This method has the disadvantage that all the surfaces with which the pests enter REF can not be treated. : 193792 in contact, and that it is difficult to reach all the pests with this method since some remain in their hidden places. In addition, during the application, any other operations must be interrupted. A further problem is due to the fact that the pests are able to detect insecticidally active compounds, in particular pyrethroids, in their surroundings and to specifically avoid the surfaces treated with them. The resulting repellent effect reduces the efficacy, which generally requires one or more subsequent treatments.

To ensure the desired effectiveness of the atomizers, application rates of 7.5 to 500 mg of active compound / m2 of treated area per application are required, depending on the class of chemically active compounds. Another method for the control of arthropods using the products that have a contact action are insecticide-containing powders. WO-A2-01 / 91560 discloses formulations having an arthropodicidal contacting action employing at least two etheric vegetable oils in an appropriate vehicle. In agriculture, the use of gel-like formulations containing insecticides having a contacting action against Lepidoptera, for example moth (Cydia pomonella), (EP-A1-0 721 735 and WO-Al-97/05778) has been described. ). In addition to many other insects, activity against cockroaches is also claimed; however, this is not illustrated with respect to the application and the action. In particular, no indirect contact effects of any kind are described. In veterinary medicine, the use of gel-like formulations containing acaricides with contact action against ticks (Ioxodes ri zinus) (W0-Al-2005/015993) has been described. Here, indirect effects on pest control have not been described either. "Secondary Transmission of Toxic Baits in German Cockroach (Dictyoptera Blattellidae)" Journal of Economic Entomology, 200, 93, pages 434 to 440, examines the influence of side effects on pest control. The study focuses on the following side effects: (1) The effect of cannibalism on pest control is studied, where pests contaminated with bait are eaten by other uncontaminated pests. (2) In addition, the study examines the expansion of insecticidal action compositions by bait-infected pests, where the insecticidal action composition is transferred through social contacts from contaminated pests to uncontaminated pests, for example, by wounds caused by stings or by mutual sensation of pests. (3) A third point that is investigated in the study is the effect of residual bait that adheres to pests, which is distributed by pests that move around, resulting in additional pests that are eradicated. In all three partial aspects of the study, baits are used which, for the applicant, are disadvantageous since they are only effective when ingested by the plague. In this way, the success of this passive method of pest control depends mainly on itself and to what extent the baits are ingested by the pests. In summary, it can be stated that, first, the only known control methods are those in which a directly acting contact insecticide product, often in the form of an aqueous spray solution, is applied in a complicated manner. According to known methods, the compositions have to be applied to a large area. Therefore, large amounts of atomization and high application rates of active compound are required. These known methods also have the disadvantage that they exhibit weaknesses in their activity against resistant arthropods, they can cause repellent effects in the case of pyrethroid-containing sprays and require that all operations in the rooms to be treated be interrupted during the application of the product. Second, methods for pest control using methods locally, such as passives, baits, are known. These methods are disadvantageous due to the fact that they depend on the baits that are ingested by the pests. There was a need for a method for the control of arthropods that, in a short period, would essentially kill the entire pest population and not have the disadvantages mentioned above. Therefore, the present invention relates to an active arthropod control method which is based on an indirect and very efficient contact action. In the context of the present invention, an active method will be understood to mean a method whose effectiveness is essentially independent of the feeding behavior of the arthropods. Therefore, the invention provides a method for the control of arthropods, wherein an effective amount of a pesticide is applied to the surfaces on which the arthropods consume time, in which they move and / or in which they will move, characterized in that the pesticide: a) will kill only by contact, b) is applied in small amounts in small areas, c) comprises at least one insecticidally active compound, d) is a viscous liquid, e) adheres to the arthropods so well which is expanded by the arthropods in the surrounding area, f) optionally comprises attractants, g) optionally comprises UV absorption substances, h) optionally comprises one or more synergists, i) optionally comprises other additives. The pesticide to be used according to the invention has a contact action against the arthropods and is applied in small amounts to small areas. According to the invention, small amounts refer to active compound amounts as small as, in general, from 0.1 to 10 mg of active compound per m2, preferably from 0.25 to 5 mg of active compound per m2, particularly preferably from 0.5 to 2.5 mg of active compound per m2. Thus, with respect to the formulation, in general, the amount of pesticide is between 10 and 1000 mg of formulation per m2, preferably between 25 and 500 mg / m2, particularly preferably between 50 and 250 mg / m2. The formulations used in the method according to the invention are applied in a manner known to the person skilled in the art. The pesticide can be used either as an open application directly to the areas in which the arthropods move (for example, by means of a cartridge, a dispenser dispenser, syringes, brushes, atomization cans), or covered in appropriate devices ( for example, boxes, tubes and tunnels with access to pests) or expand on an appropriate support (eg, cardboard, plastic). The devices or supports are placed in the areas in which the arthropods move. In the method according to the invention, the pesticide is applied preferably expanded, in the form of a line or in the form of a stain. With particular preference, the pesticide is applied only to a small area. In the case of application to an area, small area means that the pesticide is applied to an area in general of 50 to 500 cm2, in particular of 60 to 400 cm2, preferably of 70 to 300 cm2, particularly preferably of 80 at 200 cm2. Furthermore, in the case of the application as a stain, small area means that the pesticide is generally applied from 1 to 50 cm2, in particular from 2 to 40 cm2, preferably from 3 to 30 cm2, particularly preferably from 4 to 30 cm2. 40 cm2. Here, what was established above refers to a total area of 25 m2.

It is preferred that the application be carried out not only at one site, but at different sites expanded through the surface to be treated. In a preferred embodiment of the method according to the invention, the pesticide is applied from 2 to 50, in particular from 3 to 40, preferably from 4 to 35, particularly preferably from 5 to 30, different sites expanded on the surface. Here, what was established above refers to a total area of 25 m2. In a preferred embodiment, of the method according to the invention, the pesticide is not a bait.

Particularly preferred as active compounds to be used according to the invention are pyrethroids and arylpyrazoles. Particular preference is given to delta etrin and fipronil. Preferably, the pesticide to be used in the method according to the invention comprises at least one oil moderately miscible with water. This will be understood as meaning all oily liquids of synthetic or natural origin containing straight or branched chain groups, optionally functional, having one or more unsaturated bonds between 2 carbon atoms and having a solubility in water of less than 1 g / 1. Preference is given to unsaturated oils of vegetable or animal origin that have a higher content of unsaturated fatty acids. Examples of such are flax seed oil, palm oil, peanut oil, cottonseed oil, soybean oil, sunflower oil, rape seed oil, castor oil and fish oil. Particular preference is given to castor oil. However, in order to prepare the compositions according to the invention, it is also possible to use the fatty acids present in the oils, or the compounds that are obtained by chemical modification of the fatty acids, such as, for example, ethoxylates of fatty acids. Examples of such fatty acids which can be used by themselves as a mixture are myristoleic acid, palmitoleic acid, oleic acid, gadoleic acid, ricinoleic acid, linoleic acid, linolenic acid, arachidonic acid and clupanodonic acid. By selecting an appropriate combination of the active compound and the moderately miscible oil in water, preferably, an appropriate pesticidal viscosity is obtained in the context of the present invention. Here, the viscosity of the liquid is preferably chosen so that it initially adheres to the surface to be treated, but adheres simultaneously to the arthropods to control itself sufficiently well, so that in contact with this liquid, they expand the pesticide until they die. In accordance with the invention, it was found that the resulting pesticide preferably has a viscosity of 400 to 100,000 mPa · s, particularly preferably 900 to 60,000 mPa-s, more preferably 1,500 to 40,000 mPa · s. Here, the viscosity is determined using an RS 150 Haake viscometer, measuring in a Z20 beaker with a cutting speed of 7.5 [1 / s]. Adhesive properties can also be achieved by using sugar syrups. Therefore, in a further embodiment of the present invention, the pesticide to be used in the method according to the invention comprises a sugar syrup or a mixture of different sugar syrups. Sugar syrups that may be mentioned in this regard are invert sugar syrups, molasses, special sugar syrups, caramel sugar syrups, mixed syrups and glucose syrups. Viscosity can also be adjusted using thickeners. These thickeners can be used alone or as a mixture of two or more agents in any ratio. Suitable for use as thickeners are organic and inorganic macromolecules. The organic macromolecules which may be mentioned are the cellulose derivatives, for example, hydroxypropylcellulose, hydroxyethylcellulose, methylcellulose, sodium carboxymethylcellulose, hydroxypropylmethylcellulose, hydroxyethylmethylcellulose, hydroxyethylpropylcellulose and also the xanthines, alginates, carrageenan, agar-agar, polyvinyl alcohols, polyvinylpyrrolidone, polyacrylic acid and polymethacrylic acid. The inorganic macromolecules (inorganic gel formers) which may be mentioned are finely divided silica and its hydrophobic derivatives and bentonite (for example, Rudolf Voigt, Pharmazeutische Technologie [Pharmaceutical Technology], pages 362-385, Ulstein Mosby). Preference is given to the use of methylcellulose, hydroxyethylcellulose, sodium carboxymethylcellulose, hydroxypropylcellulose, xanthenes, polyacrylic acid and polymethacrylic acid, finely divided silica and their hydrophobized derivatives. Particular preference is given to the use of methylcellulose, hydroxyethylcellulose, sodium carboxymethylcellulose, polyacrylic acid, finely divided silica and their hydrophobized derivatives. In general, the pesticide formulations to be used according to the invention also comprise emulsifiers. Suitable emulsifiers are all customary nonionic, anionic, cationic and zwitterionic compounds having surface active properties that are customarily used in agrochemical compositions. These compounds include the reaction products of fatty acids, fatty esters, fatty alcohols, fatty amines, alkylphenols or alkylarylphenols with ethylene oxide and / or propylene oxide and / or butylene oxide and also sulfuric esters, phosphoric monoesters and phosphoric diesters thereof, furthermore the reaction products of ethylene oxide with propylene oxide, further alkylsulfonates, alkyl sulfates, aryl sulphates, tetraalkylammonium halides, trialkylarylammonium halides and alkylaminesulfonates. The emulsifiers can be used alone or even as a mixture. The reaction products of castor oil with ethylene oxide in a molar ratio of 1:20 to 1:60, reaction products of C6-C2o alcohols with ethylene oxide in a molar ratio of 1: 5 may be mentioned as preferred. 1:50, the reaction products of fatty amines with ethylene oxide in a molar ratio of 1: 2 to 1:25, the reaction products of 1 mole of phenol with 2 to 3 moles of styrene and 10 to 50 moles of ethylene oxide, the reaction products of Cß-C? 2 alkylphenols with ethylene oxide in a molar ratio of 1: 5 to 1:30, alkyl glucosides, C8-Ci6 alkylbenzenesulfonic acid salts, such as, for example, salts of calcium, monoethanolamine, diethanolammonium and triethanolammonium. Examples of the nonionic emulsifiers which may be mentioned are the products known under the names Pluronic PE 10 100 (ex BASF), Atlox 4913 (ex Uniqema) and Emulgator KS (ex Lanxess AG). The tristyrylphenyl ethoxylates are also suitable. Examples of the anionic emulsifiers which may be mentioned are the product Lanxess AG commercially available under the name Baykanol SL (= condensate of the ditolyl ether sulfonate with formaldehyde) and also the ethoxylates of tristyrylphenol phosphated or sulphated, where special mention may be made of Soprophor FLK and Soprophor 4D 384 (from Rhodia). It may be possible to improve the activity using additional additives. The following compounds can be used. • Attractants, such as sex pheromones, aggregation pheromones and aromas (artificial, identical to the natural or natural product). Particular preference is given to quinones of Blatella, periplanone A, periplanone B, and Supella pironas and also to LEJ829L (parahydroxyphenylacetic acid), banana flavor, cherry flavor and also blackcurrant aroma. • UV absorbers: means substances capable of absorbing UV light, preferably the radiation of sunlight in a wavelength range of 270 to 400 nm. • Synergists: it will be understood that means substances that, together with the insecticidally active compound, achieve a super-additive activity, for example piperonyl butoxide, MGK 264 (octacid) or sesamex. Other additives, such as Bitrex, dyes, pigments. The concentrations of the components mentioned individually above in the compositions on which the method according to the invention is based can be varied within a relatively wide range. In this way, the concentrations present after the removal of any water contained in the compositions used, if present, are: of atropo-didally active compounds in general between 0.1 and 10% by weight, preferably between 0.5 and 5% by weight, very particularly preferably between 0.5 and 2% by weight, - of viscous liquids with good adhesion, in general between 10 and 99% by weight, preferably between 50 and 95% by weight, very particularly, preferably between 80 and 95% by weight, - of attractants, in general between 0.01 and 5% by weight, preferably between 0.05 and 1% by weight, very particularly preferably between 0.05 and 0.2% by weight, - of UV absorbers, in general between 1 and 40 % by weight, preferably between 5 and 20% by weight, particularly preferably between 5 and 10% by weight, - of additives, in general between 1 and 70% by weight, preferably between 2 and 35% by weight, very particularly, preferably between 3 and 20% by weight. Advantageously, the pesticide to be used according to the process according to the invention can be present as a ready-to-use formulation. In this way, a new method has been found, simple and highly effective to control arthropods that, making use of a viscous ready-to-use formulation containing insecticide, overcomes the disadvantages of conventional atomizers. When the method according to the invention was employed, it was found that, after contact of the arthropods with this formulation, a small portion of the viscous liquid adheres to the arthropods and is released by the arthropods themselves onto the surfaces, in particular at his place of hiding. Here, it is extremely surprising that a simple contact of other arthropods with these surfaces provided with the pesticide by the arthropods themselves, is also sufficient to kill these pests, quickly and reliably. In the context of the present invention, this is understood as an action referred to as indirect. In addition, it was surprising that there is a pronounced flood effect carried out at the hiding places of the arthropods. This flood effect results in greater contact of the normally non-mobile stages of a pest population with the insecticidal composition, which considerably improves the overall success of the treatment. In a particular embodiment of the present invention, therefore, the method for controlling arthropods, wherein the arthropods are killed by contact with a pesticide and the pesticide is distributed by the arthropods themselves. By virtue of the type of formulation selected especially from the pesticide for the method according to the invention, surprisingly, there are no repellent effects as in the case of other compositions, in the particular pyrethroids. The method according to the invention reliably controls even the arthropods that have developed resistance to the chemically active formulation ingredients or ingredients of conventional pesticides. With good results, the method according to the invention can be used to kill harmful or annoying arthropods, in particular insects that live socially or in close contact with each other. The method according to the invention is suitable for controlling harmful or annoying arthropods in buildings, such as, for example, rooms, and in the immediate vicinity of buildings and exteriors. An additional area of use is the protection of entry points in buildings, such as, for example, doors and benefits (called perimeter treatment). The method according to the invention is based on the targeted application of a pesticide already advantageously present in a form ready for use to the surfaces frequented by the arthropods, inside and outside the buildings. These surfaces can be located within the hiding places (for example, in drawers, in front of buildings, pipes, cracks and interstices) and also outside (for example, in corners, edges, cover bands).

By applying very small amounts of the active compound / m2 at a few sites (such as, for example, only at individual points), the method according to the invention allows control of the total plague population within a very short period.

In the method according to the invention, high efficiency is obtained even if one or more body parts of the arthropods (eg, parts of antennae, legs, mouth) come into contact with the composition only once. Since the arthropod continues to move until the action begins, small amounts of the formulation expand over the surfaces. These small amounts are sufficient to kill other arthropods using the same routes by the action of indirect contact. The formulation containing the insecticide is also transferred by social contact between the arthropods. In the case of some synthetic pyrethroids, by virtue of the method according to the invention, there is a pronouncing effect that improves the activity once the composition is introduced into the hiding places of the arthropods. With very good results, the method according to the invention can be used to control the harmful or annoying arthropods in the control of private and professional pests, in the control of termites, in agriculture, in the protection of stored products, in the protection of materials, in the control of vectors, in gardens and in forests.

More preferably, the method according to the invention is suitable for controlling cockroaches (representative of the order Blattaria), ants (representative of the order Hymenoptera) and termites (representative of the order Isoptera). The following working examples illustrate the method according to the invention, but do not limit the present invention.

WORK EXAMPLES The method according to the invention and the mode of action on which it is based are illustrated in the following examples.

Formulation Example 1 A formulation comprises the following components: The castor oil is initially charged in a beaker and, with stirring (toothed disk agitator), is heated to 80 ° C. At this temperature, deltamethrin is added and the mixture is stirred for 120 minutes. Then Aerosil is added and stirring is continued at 80 ° C for a further 10 minutes. After addition of the emulsifier and further stirring at 80 ° C for 10 minutes, the gel formed, with stirring, is cooled to room temperature.

Example A To examine how fast the action begins after the simple contact, the rear leg, in each case, of a male German cockroach. { Bla tella germáni ca) is contacted for a short time with the contact formulations to be tested. After this simple and short contact, the insect is transferred in a plastic beaker (base: 7.5 cm in diameter, height: 9.5 cm) which is closed with a transparent lid. The time is measured until the fulmination effect begins. This "flash time" is taken as a measure of how quickly the insecticidal action of the composition in question begins. The lower the value, the faster the formulation acts. The results of the test are shown in the following table.

For the example of using a formulation according to Formulation Example 1, wherein the active compound is varied according to the above table and different amounts of the active compound are made for the appropriate adjustment of the quantity of castor oil compared to Formulation Example 1 Example B To test the efficacy after direct contact of the harmful insects, a mixed population (5 males, 5 females, 10 intermediate stage larvae of the German cockroach (Bla tella germáni ca)) is established in a test arena (50 x 60 cm, height 15 cm), internal walls covered with talc. In this test arena, there is a drinker (third away) and in one of the far corners there is a hidden place and in one of the nearby corners a piece of biscuit. After one day, the cockroaches are exposed to the method according to the invention, that is, 200 mg of the viscous formulation are placed in a Petri dish at the free-standing corner of the test arena. For the quantitative evaluation of efficacy, the mortality of adult animals and larvae are determined separately, 1, 2, 3 and 6 days after the start of the test. The test results are shown in the following table.

For the example, a formulation according to Formulation Example 1 is used, wherein the active compound is varied according to the table above and the different amounts of the active compound will be made for the proper adjustment of the amount of castor oil compared to Formulation Example 1.

EXAMPLE C To test indirect efficacy, after the test has ended the first presentation of the composition of the test sands of Example B is removed, as are all dead insects. A new mixed group of male and female animals and larvae of the German cockroach (Germanic Blattella) are then placed together in this test arena. During the entire duration of the test, the animals have access to the feed, water and the hide-away site of Example B. For the quantitative evaluation of the effectiveness, the mortality of the adult animals and the larvae is determined separately, 1 2, 3 and 6 days after the start of the test. The results of the test are shown in the following table.

For the example, a formulation according to Formulation Example 1 is used, wherein the active compound is varied according to the table above and the different amounts of the active compound will be elaborated for the appropriate adjustment of the amount of castor oil compared with Formulation Example 1. It is noted that with respect to this date, the best method known by the applicant to carry out the aforementioned invention is that which is clear from the present description of the invention.
