Certain 1,2,4,5-triazine derivatives are proposed in the literature as active ingredients in compositions for controlling pests on domestic animals and productive livestock and in crops of useful plants. The biological properties of those known compounds are not entirely satisfactory in the field of pest control, however, for which reason there is a need to provide further compounds having pesticidal properties, that problem being solved according to the invention by the provision of the present compounds of formula (I). The compounds of formula (I) may be in the form of salts or may form e.g. acid addition salts. The latter are formed, for example, with strong inorganic acids, such as mineral acids, e.g. sulfuric acid, a phosphoric acid or a hydrohalic acid, with strong organic carboxyiic acids, such as unsubstituted or substituted, e.g. halo-substituted, C 1 -C alkanecarboxylic acids, for example acetic acid, saturated or unsaturated dicarboxylic acids, e.g. oxalic, malonic, maleic, fumaric or phthalic acid, hydroxycarboxylic acids, e.g. ascorbic, lactic, malic, tartaric or citric acid, or benzoic acid, or with organic sulfonic acids, such as unsubstituted or substituted, e.g. halo-substituted, d-C 4 alkane- or aryl-sulfonic acids, e.g. methane- or p- toluene-sulfonic acid. Furthermore, compounds of formula (I) having at least one acid group may form salts with bases. Suitable salts with bases are, for example, metal salts, such as alkali metal or alkaline earth metal salts, e.g. sodium, potassium or magnesium salts, or salts with ammonia or an organic amine, such as morpholine, piperidine, pyrrolidine, a mono-, di- or tri-lower alkylamine, e.g. ethyl-, diethyl-, triethyl- or dimethyl-propyl-amine, or a mono-, di- or tri-hydroxy-lower alkylamine, e.g. mono-, di- or tri-ethanolamine.

Within the scope of the invention preference is given especially to the compounds of formula (I) listed in Tables 1 to 5 and more especially to the compounds of formula (I) mentioned in the Synthesis Examples. The invention relates also to a process for the preparation of compounds of formula (I), in each case in free form or in salt form, which process comprises, for example, a) reacting a compound of formula which compounds are known or can be prepared analogously to corresponding known compounds and in which X 1 ( X 2 and X 3 are as defined for formula (I) and Q- . is a leaving group, optionally in the presence of a catalyst, with a compound of formula Q, H 2 N-HN ^-Ar, — A — Ar 2 (Ilia) or V~ Ar ι — A — Ar 2 (1Mb), respectively, O O which compounds are known or can be prepared analogously to corresponding known compounds and in which An, A and Ar 2 are as defined for formula (I) and Q- . is a leaving group, reacting the resulting product, optionally after isolation thereof, with a chlorinating agent, reacting the resulting chlorination product, optionally after isolation thereof again, with hydrazine, and reacting the resulting dihydrotetrazine derivative, optionally after isolation thereof again, with an oxidising agent, or b) for the preparation of a compound of formula (I) wherein A is a single bond, reacting in accordance with process a) a compound of formula (II) with a compound of formula Q, H 2 N-HN ^Ar— Q 2 (Iva) or ^-A rι - Q 2 (iVb), O O which compounds are known or can be prepared analogously to corresponding known compounds and in which An is as defined for formula (I) and d and Q 2 are leaving groups, and reacting the resulting product with a compound of formula OH Ar 2 B (V), OH which compound is known or can be prepared analogously to corresponding known compounds and in which Ar 2 is as defined for formula (I), and in each case, if desired, converting a compound of formula (I), in each case in free form or in salt form, obtainable in accordance with the process or by another method into a different compound of formula (I), separating a mixture of isomers obtainable in accordance with the process and isolating the desired isomer and/or converting a free compound of formula (I) obtainable in accordance with the process into a salt or converting a salt of a compound of formula (I) obtainable in accordance with the process into the free compound of formula (I) or into a different salt. Variant a): The reactants can be reacted with one another as such, that is to say without the addition of a solvent or diluent, for example in the molten state. Generally, however, it is advantageous to add an inert solvent or diluent or a mixture thereof. Examples of solvents and diluents include: aromatic, aliphatic and alicyclic hydrocarbons and halogenated hydrocarbons, such as benzene, toluene, xylene, mesitylene, Tetralin, chlorobenzene, dichlorobenzene, bromo- benzene, petroleum ether, hexane, cyclohexane, dichloromethane, trichloromethane, tetra- chloromethane, dichloroethane, trichloroethene and tetrachloroethene; ethers, such as diethyl ether, dipropyl ether, diisopropyl ether, dibutyl ether, tert-butyl methyl ether, ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, ethylene glycol dimethyl ether, dimethoxydiethyl ether, tetrahydrofuran and dioxane; ketones, such as acetone, methyl ethyl ketone and methyl isobutyl ketone; amides, such as N,N-dimethylformamide, N,N-diethyl- formamide, N,N-dimethylacetamide, N-methylpyrrolidone and hexamethylphosphoric acid triamide; nitriles, such as acetonitrile and propionitrile; and sulfoxides, such as dimethyl sulfoxide. Preferred leaving groups are halogens, tosylates, mesylates and triflates, especially halogens, more especially chlorine and bromine. Suitable basic catalysts are tertiary amines and aza-aromatic compounds, preferably trialkylamines and substituted pyridines, especially triethylamine and 4-dimethylamino- pyridine. Suitable chlorinating agents are (COCI) 2 , SOCI 2 , SO 2 CI 2 , PCI 3 , POCI 3 and PCI 5 , preferably PCI 5 . Suitable oxidising agents are halogens, O 2 and nitrite salts, preferably sodium nitrite. The reactions are advantageously effected in a temperature range of from about 0°C to about +120°C, preferably from about 0°C to about +80°C. In a preferred embodiment of variant a), a compound of formula (Ila) is reacted with a compound of formula (III) at from about 0° to about 30°, preferably about 10°, in a halogenated hydrocarbon, preferably methylene chloride, in the presence of a basic catalyst mixture, preferably a mixture of triethylamine and 4-dimethylaminopyridine; the resulting product is isolated, reacted with a chlorinating agent, preferably PCI 5 , at from about 80° to about 120°, preferably about 110°, in a halogenated hydrocarbon, preferably chlorobenzene, and the resulting chlorination product is then isolated again and reacted with hydrazine at about from 0° to 40°, preferably 20°, in an ether, preferably tetrahydrofuran; the resulting dihydro- tetrazine derivative is isolated and reacted with an oxidising agent, preferably sodium nitrite, at from about 0° to about 80°, preferably about 40°, in a water/acid mixture, preferably water/acetic acid, to form the tetrazine derivative. Variant b): The reactants can be reacted with one another as such, that is to say without the addition of a solvent or diluent, for example in the molten state. Generally, however, it is advantageous to add an inert solvent or diluent or a mixture thereof. Examples of solvents and diluents are given in variant a). Suitable leaving groups, basic catalysts, chlorinating agents and oxidising agents are those mentioned in variant a). Suitable catalysts for the reaction with a compound of formula (V) are palladium complexes, e.g. tetrakis(triphenylphosphine)palladium. In a preferred embodiment of variant b), a tetrazine derivative is first prepared in accordance with variant a) and is then reacted with a compound of formula (V) at about from 0° to 80°, preferably 50°, in an ether, preferably dimethoxyethane, in the presence of a catalyst, preferably tetrakis(triphenylphosphine)palladium. Salts of compounds of formula (I) can be prepared in a manner known per se. For example, acid addition salts of compounds of formula (I) are obtained by treatment with a suitable acid or a suitable ion exchange reagent and salts with bases are obtained by treatment with a suitable base or a suitable ion exchange reagent. Salts of compounds of formula (I) can be converted into the free compounds of formula (I) in customary manner: acid addition salts, for example, by treatment with a suitable basic agent or a suitable ion exchange reagent and salts with bases, for example, by treatment with a suitable acid or a suitable ion exchange reagent. Salts of compounds of formula (I) can be converted in a manner known per se into other salts of compounds of formula (I); for example, acid addition salts can be converted into other acid addition salts, for example by treatment of a salt of an inorganic acid, such as a hydrochloride, with a suitable metal salt, such as a sodium, barium or silver salt, of an acid, for example with silver acetate, in a suitable solvent in which an inorganic salt that forms, for example silver chloride, is insoluble and thus precipitates out from the reaction mixture. Depending upon the procedure and reaction conditions, the compounds of formula (I) that have salt-forming properties may be obtained in free form or in the form of salts. The compounds of formula (I) may also be obtained in the form of their hydrates and/or may include other solvents, for example solvents used for the crystallisation of compounds in solid form. The invention relates to all those forms of the process in which a compound obtainable as starting compound or intermediate at any stage of the process is used as starting material and all or some of the remaining steps are carried out or a starting material is used in the form of a derivative or salt or, especially, is formed under the reaction conditions. In the process of the present invention it is preferable to use those starting materials and intermediates which result in the compounds of formula (I) described at the beginning as being especially valuable. The invention relates especially to the processes described in the Preparation Examples. The invention relates also to novel starting materials and intermediates, in each case in free form or in salt form, used according to the invention for the preparation of the compounds of formula (I) and their salts, to the use of those novel starting materials and intermediates and to processes for their preparation. The invention relates especially also to compounds of formula wherein Xi, X 2 , X 3 , Q 1 t An, A and Ar 2 are as defined above, to the use thereof and to processes for their preparation. Furthermore, the compounds of formula (la) exhibit a spectrum of activity similar to that of compounds of formula (I) and can be used in the same manner. The present invention relates also to the compounds of formula (la) as active ingredients and in respect of their use in agrochemical compositions. In the area of pest control, the compounds of formula (I) according to the invention are active ingredients exhibiting valuable preventive and/or curative activity with a very advantageous biocidal spectrum, even at low rates of concentration, while being well tolerated by warmblooded animals, fish and plants. The active ingredients according to the invention are effective against all or individual development stages of normally sensitive animal pests, but also of resistant animal pests, such as insects and representatives of the order Acarina. The insecticidal, ovicidal and/or acaricidal activity of the active ingredients according to the invention may manifest itself directly, i.e. in the mortality of the pests, which occurs immediately or only after some time, for example during moulting, or of their eggs, or indirectly, for example in reduced oviposition and/or hatching rate, good activity corresponding to a mortality of at least 50 to 60 %. The said animal pests include, for example, those mentioned in European Patent Application EP-A-736 252, page 5, line 55, to page 6, line 55. The pests listed therein are therefore included by reference in the subject matter of the present invention. The compounds according to the invention can be used to control, i.e. to inhibit or destroy, pests of the mentioned type occurring especially on plants, more especially on useful plants and ornamentals in agriculture, in horticulture and in forestry, or on parts of such plants, such as the fruits, blossoms, leaves, stems, tubers or roots, while in some cases parts of plants that grow later are still protected against those pests. Target crops include both natural crops and crops that have been modified by breeding or genetic methods, especially cereals, such as wheat, barley, rye, oats, rice, maize and sorghum; beet, such as sugar beet and fodder beet; fruit, e.g. pomes, stone fruit and soft fruit, such as apples, pears, plums, peaches, almonds, cherries and berries, e.g. strawberries, raspberries and blackberries; leguminous plants, such as beans, lentils, peas and soybeans; oil plants, such as rape, mustard, poppy, olives, sunflowers, coconut, castor oil, cocoa and groundnuts; cucurbitaceae, such as marrows, cucumbers and melons; fibre plants, such as cotton, flax, hemp and jute; citrus fruits, such as oranges, lemons, grapefruit and mandarins; vegetables, such as spinach, lettuce, asparagus, cabbages, carrots, onions, tomatoes, potatoes and paprika; lauraceae, such as avocado, cinnamon and camphor; and tobacco, nuts, coffee, aubergines, sugar cane, tea, pepper, vines, hops, bananas, natural rubber plants and ornamentals. The compounds according to the invention are especially suitable for controlling insects and representatives of the order Acarina, especially plant-destructive feeding insects, such as Anthonomus grandis, Diabrotica balteata, Heliothis virescens larvae, Plutella xylostella and Spodoptera littoralis larvae, and spider mites, such as Tetranychus spp., in cotton, fruit, citrus, maize, soybean, rape and vegetable crops. The compositions according to the invention are also suitable for protecting plant propagation material, e.g. seed, such as fruits, tubers or grains, or plant cuttings, against fungal infections and animal pests. The propagation material can be treated with the composition before planting: seed, for example, can be dressed before being sown. The active ingredients according to the invention can also be applied to grains (coating), either by impregnating the seeds in a liquid formulation or by coating them with a solid formulation. The composition can also be applied to the planting site when the propagation material is being planted, for example to the seed furrow during sowing. The invention relates also to such methods of treating plant propagation material and to the plant propagation material so treated. Further areas of use of the compounds according to the invention are the protection of stored goods and storerooms and the protection of raw materials, and also in the hygiene sector, especially in the protection of warm-blooded animals, including farm animals, such as cows, pigs, sheep and goats, poultry, such as hens, turkeys and geese, animals bred for their fur, such as mink, foxes, chinchillas, rabbits and the like, and also domestic animals and pets, such as cats and dogs, and even human beings, against pests of the mentioned type. For example, flea infestation in domestic animals and pets is a problem for the animal owner for which there is still no adequate solution. Owing to the complicated life cycle of the flea, none of the known methods of controlling fleas is totally satisfactory, especially since most of the known methods are aimed principally at controlling the fully grown fleas in the coat and take no account at all of the various juvenile stages of the fleas, which live not only in the animal's coat, but also on the floor, on carpets, on the animal's sleeping place, on chairs, in the garden and in all the other places with which the infested animal comes into contact. Flea treatment is generally expensive and must be continued for prolonged periods, success generally being achieved only when the treatment is applied not only to the affected animal, e.g. the dog or cat, but also simultaneously to all the places frequented by the affected animal. The compounds of formula (I) according to the invention can be used alone or in combination with other biocides. For example, in order to enhance the effect they can be combined with pesticides having the same direction of action or in order to broaden the spectrum of activity they can be combined with substances having a different direction of action. Where it is desired to extend the spectrum of activity to endoparasites, e.g. worms, the compounds of formula (I) are advantageously combined with substances having endoparasiticidal properties. They can, of course, also be used in combination with anti-bacterial agents. Especially suitable mixing partners are, for example: azamethiphos; chlorfenvinphos; cypermethrin, cypermethrin high-cis; cyromazine; diafenthiuron; diazinon; dichlorvos; dicrotophos; dicyclanil; fenoxycarb; fluazuron; furathiocarb; isazofos; iodofenphos; kinoprene; lufenuron; methacriphos; methidathion; monocrotophos; phosphamidon; profenofos; diofenolan; a substance obtainable from the Bacillus thuringiensis strain GC91 or from NCTC11821; pymetrozine; bromopropylate; methoprene; disulfoton; quinalphos; tau- fluvalinate; thiocyclam; thiometon; aldicarb; azinphos-methyl; benfuracarb; bifenthrin; buprofezin; carbofuran; dibutylaminothio; cartap; chlorfluazuron; chlorpyrifos; cyfluthrin; lambda-cyhalothrin; alpha-cypermethrin; zeta-cypermethrin; deltamethrin; diflubenzuron; endosulfan; ethiofencarb; fenitrothion; fenobucarb; fenvalerate; formothion; methiocarb; heptenophos; imidacloprid; isoprocarb; methamidophos; methomyl; mevinphos; parathion; parathion-methyl; phosalone; pirimicarb; propoxur; teflubenzuron; terbufos; triazamate; abamectin; fenobucarb; tebufenozide; fipronil; beta-cyfluthrin; silafluofen; fenpyroximate; pyridaben; fenazaquin; pyriproxyfen; pyrimidifen; nitenpyram; NI-25, acetamiprid; avermectin ι (abamectin); an insect-active extract from a plant; a preparation containing insect-active nematodes; a preparation obtainable from Bacillus subtilis; a preparation containing insect- active fungi; a preparation containing insect-active viruses; AC 303 630; acephate; acrinathrin; alanycarb; alphamethrin; amitraz; AZ 60541 ; azinphos A; azinphos M; azo- cyclotin; bendiocarb; bensultap; beta-cyfluthrin; BPMC; brofenprox; bromophos A; bufen- carbe; butocarboxim; butylpyridaben; cadusafos; carbaryl; carbophenothion; chloethocarb; chlorethoxyfos; chlormephos; cis-res-methrin; clocythrin; clofentezine; cyanophos; cyclo- prothrin; cyhexatin; demeton-M; demeton-S; demeton-S-methyl; dichlofenthion; dicliphos; diethion; dimethoate; dimethylvinphos; dioxathion; edifenphos; emamectin; esfenvalerate; ethion; ethofenprox; ethoprophos; etrimphos; fenamiphos; fenbutatin oxide; fenothiocarb; fenpropathrin; fenpyrad; fenthion; fluazinam; flucycloxuron; flucythrinate; flufenoxuron; flufenprox; fonophos; fosthiazate; fubfenprox; HCH; hexaflumuron; hexythiazox; iprobenfos; isofenphos; isoxathion; ivermectin; lambda-cyhalothrin; malathion; mecarbam; mesulfen- phos; metaldehyde; metolcarb; milbemectin; moxidectin; naled; NC 184; omethoate; oxamyl; oxydemethon M; oxydeprofos; permethrin; phenthoate; phorate; phosmet; phoxim; pirimiphos M; pirimiphos A; promecarb; propaphos; prothiofos; prothoate; pyraclophos; pyrida-phenthion; pyresmethrin; pyrethrum; RH 5992; salithion; sebufos; sulfotep; sulprofos; tebufenpyrad; tebupirimphos; tefluthrin; temephos; terbam; tetrachlorvinphos; thiacloprid; thiamethoxam; thiafenox; thiodicarb; thiofanox; thionazin; thuringiensin; tralomethrin; triarathen; triazophos; triazuron; trichlorfon; triflumuron; trimethacarb; vamidothion; xylylcarb; Yl 5301/5302; zetamethrin; DPX-MP062; RH-2485; D 2341 or XMC (3,5-xylyl methyl- carbamate). The good pesticidal activity of the compounds of formula (I) according to the invention corresponds to a mortality of at least 50-60 % of the mentioned pests. The methods of applying the crop protection agents, i.e. the methods for controlling pests of said type, such as spraying, atomizing, dusting, coating, dressing, scattering or pouring (chosen in accordance with the intended objectives and prevailing circumstances), and the use of the compositions for controlling pests of said type are further objects of the invention. Typical concentrations of active ingredient are between 0.1 and 1000 ppm, preferably between 0.1 and 500 ppm. The rates of application are generally 1 to 2000 g of active ingredient (a.i.) per hectare (ha = approximately 2.471 acres), especially 10 to 1000 g a.i./ha, and preferably 20 to 600 g a.i./ha. The compounds of formula (I) are used in unmodified form or, preferably, together with the adjuvants conventionally employed in formulation technology and can therefore be formulated in known manner e.g. into emulsifiable concentrates, directly sprayable or dilutable solutions, dilute emulsions, wettable powders, soluble powders, dusts, granules, and also encapsulations in polymer substances. As with the nature of the compositions, the methods of application, such as spraying, atomising, dusting, scattering or pouring, are selected in accordance with the intended objectives and the prevailing circumstances and the invention relates also thereto. The formulations, that is to say the compositions, preparations or mixtures comprising the compound (active ingredient) of formula (I), or a combination of that active ingredient with other agrochemical active ingredients and, as appropriate, a solid or liquid adjuvant, are prepared in known manner, e.g. by homogeneously mixing and/or grinding the active ingredients with extenders, for example with solvents, solid carriers, and optionally surface-active compounds (surfactants) and the invention relates also thereto. As formulation auxiliaries there are used, for example, solid carriers, solvents, stabilisers, "slow release" auxiliaries, dyes and optionally surface-active substances (surfactants). Suitable carriers and auxiliaries include all those substances customarily used in crop protection products. Suitable auxiliaries, such as solvents, solid carriers, surface-active compounds, non-ionic surfactants, cationic surfactants, anionic surfactants and other auxiliaries in the compositions used according to the invention, include e.g. those described in EP-A-736 252, page 7, line 51 to page 8, line 39; they are included by reference in the subject matter of the present invention. Suitable anionic surfactants include both so-called water-soluble soaps and water-soluble synthetic surface-active compounds. Suitable soaps are the alkali metal salts, alkaline earth metal salts or unsubstituted or substituted ammonium salts of higher fatty acids (C 10 -C 22 ), e.g. the sodium or potassium salts of oleic or stearic acid, or of natural fatty acid mixtures which can be obtained e.g. from coconut oil or tall oil. Mention may also be made of fatty acid methyltaurine salts as surfactants. More frequently, however, so-called synthetic surfactants are used, as mentioned in EP-A-736 252, especially fatty sulfonates, fatty sulfates, sulfonated benzimidazole derivatives and alkylarylsulfonates. The compounds of formula (I) are distinguished inter alia also by excellent activity against fleas, not only adult fleas being rapidly killed but also, by a circuitous route, the juvenile stages of the fleas. Flea larvae hatching out from the flea eggs feed substantially on the excreta of the adult fleas. Since the compounds of formula (I) according to the invention kill the adult fleas very rapidly, the necessary excreta are absent and the juvenile stages are deprived of nutrient medium, so that they perish before reaching the adult stage. The present invention therefore relates preferably to a method of controlling parasites on human beings, domestic animals, productive livestock and pets, wherein an effective amount of a composition comprising at least one compound of formula (I), or a physiologically tolerable salt thereof, is administered systemically or, preferably, topically to the warmblooded animal. The long-term action is achieved by the compounds of formula (I) according to the invention with various forms of administration, for example by administering the active ingredient in a formulated form externally or internally to the animal to be treated. "Formulated" in this case means, for example, in the form of a powder, a tablet or granules, in liposomes or a capsule, in the form of an emulsion, a foam or a spray, in microencapsulated form or in pour-on or spot-on form. It will be understood that all orally administrable compositions comprise, in addition to customary formulation substances, further additives that encourage the host animal to take the composition orally voluntarily, e.g. suitable odorants and flavourings. Percutaneous administration, e.g. by subcutaneous or intramuscular injection or as a depot preparation in the form of an implant, and topical application, for example in pour-on or spot- on form, represent preferred subjects of this invention on account of their being easy to carry out. A further mode of administration is oral administration, e.g. in the form of a tablet. Percutaneous and topical forms of administration are of particular interest and give excellent results. Percutaneous forms of administration include, for example, subcutaneous, intramuscular and even intravenous administration of injectable forms. In addition to the customary syringes with needles, it is also possible to use needle-less high-pressure syringe devices. Pour-on and spot-on formulations are especially preferred forms of topical administration, but administration in the form of sprays, ointments, solutions or powders may also be expedient. By selection of a suitable formulation, it is possible to enhance the ability of the active ingredients to penetrate the living tissue of the host animal and/or to maintain their availability. That is important when, for example, more sparingly soluble active ingredients are used, the low solubility of which requires means for enhancing solubility, since in such cases the animal's body fluid is capable of dissolving only small amounts of active ingredients at a time. Furthermore, in order to obtain a strongly delayed release of active ingredient, a compound of formula (I) according to the invention may also be present in a matrix formulation which physically prevents the active ingredient from being released and excreted prematurely and maintains the bioavailability of the active ingredient. Such a matrix formulation is injected into the body, e.g. intramuscularly or subcutaneously, and remains there as a form of depot from which the active ingredient is released continuously. Such matrix formulations are known to the person skilled in the art. They are generally wax-like, semi-solid substances, for example vegetable waxes and polyethylene glycols having a high molecular weight, or solid polymer formulations, for example so-called microspheres. The rate of release of the active ingredient from the implant and thus the period of time over which the implant exhibits an action is generally determined by the accuracy with which the implant has been calibrated (amount of active ingredient in the implant), the environment around the implant and the polymer formulation from which the implant has been made. The administration of veterinary medicinal additives to animal feed is well known in the field of animal health. It is usual first to prepare a so-called premix in which the active ingredient is dispersed in a liquid or is in finely divided form in solid carriers. That premix can normally comprise about 1 to 800 mg of compound per kg of premix, depending on the desired final concentration in the feed. Since the compounds of formula (I) according to the invention may be hydrolysed by the constituents of the feed, they should be formulated in a protective matrix, for example in gelatin, before being added to the premix. The present invention accordingly relates also to the aspect of controlling parasites by administering to the host animal with its food a compound of formula (I) that has been protected against hydrolysis. A compound of formula (I) according to the invention is advantageously administered in a dose of from 0.01 to 800 mg/kg, preferably from 0.1 to 200 mg/kg, especially from 0.5 to 30 mg/kg, body weight, based on the host animal. A good dose that can be routinely administered to the host animal is from 0.5 to 100 mg/kg, especially from 0.1 to 40 mg/kg, body weight. The administration is effected at suitable intervals in dependence upon the mode of administration and body weight. The total dose may vary from one species of animal to another and also within a species of animal for the same active ingredient, since it depends inter alia on the weight, age and constitution of the host animal. When used according to the invention, the compound of formula (I) according to the invention will normally be administered not in pure form but, preferably, in the form of a composition that comprises, in addition to the active ingredient, constituents that assist administration, suitable constituents being those which are tolerated by the host animal. It is of course possible, in addition to controlling the adult parasites in accordance with the invention, also to use conventional methods to control the juvenile stages of the fleas, although the latter is not absolutely essential. Such compositions to be administered in accordance with the invention generally comprise from 0.1 to 99 % by weight, especially from 0.1 to 95 % by weight, of a compound of formula (I) according to the invention and from 99.9 to 1 % by weight, especially from 99.9 to 5 % by weight, of a solid or liquid, physiologically tolerable carrier, including from 0 to 25 % by weight, especially from 0.1 to 25 % by weight, of a non-toxic dispersant. Whereas commercial products will preferably be formulated as concentrates, the end user will normally employ dilute formulations. Such formulations may also comprise further auxiliaries, such as stabilisers, antifoams, viscosity regulators, binders and tackifiers as well as other active ingredients for obtaining special effects. The physiologically tolerable carriers known from veterinary medicinal practice for oral, percutaneous and topical administration can be used as formulation auxiliaries. Some examples are given below. Suitable carriers are especially fillers, such as sugars, e.g. lactose, saccharose, mannitol or sorbitol, cellulose preparations and/or calcium phosphates, for example tricalcium phosphate or calcium hydrogen phosphate, and binders, such as starch pastes using, for example, maize, wheat, rice or potato starch, gelatin, tragacanth, methylcellulose and/or, if desired, disintegrators, such as the above-mentioned starches, also carboxymethyl starch, cross- linked polyvinylpyrrolidone, agar, alginic acid or a salt thereof, such as sodium alginate. Adjuvants are especially flow conditioners and lubricants, for example silicic acid, talc, stearic acid or salts thereof, such as magnesium or calcium stearate, and/or polyethylene glycol. Dragee cores can be provided with suitable, optionally enteric, coatings, there being used inter alia concentrated sugar solutions which may comprise gum arabic, talc, polyvinylpyrrolidone, polyethylene glycol and/or titanium dioxide, or coating solutions in suitable organic solvents or solvent mixtures, or, for the preparation of enteric coatings, solutions of suitable cellulose preparations, such as acetylcellulose phthalate or hydroxypropylmethyl- cellulose phthalate. Dyes, flavourings or pigments may be added to the tablets or dragee coatings, for example for identification purposes or to indicate different doses of active ingredient. Other orally administrable preparations are hard gelatin capsules, and also soft sealed capsules made of gelatin and a plasticiser, such as glycerol or sorbitol. The hard gelatin capsules may comprise the active ingredient in the form of granules, for example in admixture with fillers, such as lactose, binders, such as starches, and/or glidants, such as talc or magnesium stearate, and, if desired, stabilisers. In soft capsules, the active ingredient is preferably dissolved or suspended in suitable liquids, such as fatty oils, paraffin oil or liquid polyethylene glycols, to which stabilisers may likewise have been added. Preference is given inter alia to capsules that may either easily be bitten through or swallowed without being chewed. The pour-on or spot-on method comprises applying the compound of formula (I) to a locally defined area of the skin or coat, advantageously on the back of the neck or the backbone of the animal. This is carried out, for example, by applying a swab or spray of the pour-on or spot-on formulation to a relatively small area of the coat from where the active ingredient becomes distributed over a wide area of the coat almost automatically as a result of the spreading constituents of the formulation assisted by the movements of the animal. Pour-on and spot-on formulations advantageously comprise carriers that promote rapid distribution over the surface of the skin or in the coat of the host animal and are generally termed spreading oils. There are suitable, for example, oily solutions; alcoholic and iso- propanolic solutions, e.g. solutions of 2-octyl dodecanol or oleyl alcohol; solutions in esters of monocarboxylic acids, such as isopropyl myristate, isopropyl palmitate, lauric acid oxalic ester, oleic acid oleyl ester, oleic acid decyl ester, hexyl laurate, oleyl oleate, decyl oleate, capric acid esters of saturated fatty alcohols of chain length C 12 -Cι 8 ; solutions of esters of dicarboxylic acids, such as dibutyl phthalate, diisopropyl isophthalate, adipic acid diisopropyl ester, di-n-butyl adipate or solutions of esters of aliphatic acids, e.g. glycols. It may be advantageous for a dispersant known from the pharmaceutical or cosmetic industry also to be present. Examples are pyrrolidin-2-one, N-alkylpyrrolidin-2-one, acetone, polyethylene glycol and its ethers and esters, propylene glycol or synthetic triglycerides. The oily solutions include e.g. vegetable oils, such as olive oil, groundnut oil, sesame oil, pine oil, linseed oil and castor oil. The vegetable oils may also be in epoxidised form. It is also possible to use paraffins and silicone oils. Generally a pour-on or spot-on formulation will contain from 1 to 20 % by weight of a compound of formula (I), from 0.1 to 50 % by weight dispersant and from 45 to 98.9 % by weight solvent. The pour-on or spot-on method can be used especially advantageously for herd animals, such as cattle, horses, sheep and pigs, where it is difficult or time-consuming to treat all the animals orally or via injection. By virtue of its simplicity, this method can of course also be used for all other animals, including individual domestic animals and pets, and is very popular with the keepers of the animals because it can often be carried out without the expert assistance of a veterinary surgeon. Suitable for parenteral and percutaneous administration are oily injection solutions or suspensions, there being used suitable lipophilic solvents or vehicles, such as fatty oils, for example sesame oil, or synthetic fatty acid esters, for example ethyl oleate, or triglycerides, or aqueous injection solutions or suspensions that comprise viscosity-increasing substances, for example sodium carboxymethylcellulose, sorbitol and/or dextran, and, optionally, stabilisers. The preparations of the present invention can be prepared in a manner known perse, for example by means of conventional mixing, granulating, confectioning, dissolving or lyophi- lising processes. For example, pharmaceutical preparations for oral administration can be obtained by combining the active ingredient with solid carriers, optionally granulating the resulting mixture, and processing the mixture or granules, if desired or necessary after the addition of suitable excipients, to form tablets or dragee cores. The following Examples serve merely to illustrate the invention and do not limit the invention. Preferred formulations have especially the following composition (throughout, percentages are by weight): Emulsifiable concentrates: active ingredient: 1 to 90 %, preferably 5 to 20 % surface-active agent: 1 to 30 %, preferably 10 to 20 % liquid carrier: 5 to 94 %, preferably 70 to 85 % Dusts: active ingredient: 0.1 to 10 %, preferably 0.1 to 1 % solid carrier: 99.9 to 90 %, preferably 99.9 to 99 % Suspension concentrates: active ingredient: 5 to 75 %, preferably 10 to 50 % water: 94 to 24 %, preferably 88 to 30 % surface-active agent: 1 to 40 %, preferably 2 to 30 % Wettable powders: active ingredient: 0.5 to 90 %, preferably 1 to 80 % surface-active agent: 0.5 to 20 %, preferably 1 to 15 % solid carrier: 5 to 95 %, preferably 15 to 90 % Granules: active ingredient: 0.5 to 30 %, preferably 3 to 15 % solid carrier: 99.5 to 70 %, preferably 97 to 85 % Injection solution: active ingredient: 0.1 to 10 %, preferably 0.5 to 5 % non-ionic surfactant: 0.1 to 30 %, preferably 0.5 to 10 % mixture of ethanol and propylene glycol: 60 to 99 %, preferably 85 to 90 % Injection suspension (aqueous or oily): active ingredient: 0.1 to 20 %, preferably 1 to 10 % non-ionic surfactant: 0.1 to 20 %, preferably 1 to 10 % water or vegetable oil: 60 to 99 %, preferably 85 to 95 % The compositions may also comprise further ingredients, such as stabilisers, e.g. vegetable oils or epoxidised vegetable oils (epoxidised coconut oil, rapeseed oil or soybean oil), anti- foams, e.g. silicone oil, preservatives, viscosity regulators, binders and tackifiers as well as fertilisers or other active ingredients for obtaining special effects.

Synthesis Examples Example 1 : 3-(4'-Chlorobiphenyl-4-yl)-6-(2,6-difluorophenyl)-1 ,2-dihvdroπ ,2,4.51tetrazine a) 6.1 g of 4-bromobenzoic acid ethyl ester and 1.84 g of tetrakis(triphenylphosphine)- palladium are stirred in 140 ml of dimethoxyethane at room temperature for 1 h. 140 ml of 2M sodium carbonate solution and 5.0 g of 4-chlorophenylboronic acid are then added. After being stirred at room temperature for 17 h, the reaction mixture is poured into water and extracted with ethyl acetate; the organic phase is dried with sodium sulfate and concentrated and the crude product is purified by means of flash chromatography. In this way 4'-chlorobiphenyl-4-carboxylic acid ethyl ester is obtained. b) 3.04 g of 2,6-difluorobenzoic acid hydrazide, 2.7 g of triethylamine and 0.11 g of 4-di- methylaminopyridine are introduced into 20 ml of methylene chloride at 5°C and, in the course of 20 min. at 5-10°C, 3.91 g of 4-(4'-chlorophenyl)-benzoyl chloride dissolved in 20 ml of methylene chloride are added dropwise thereto. After being stirred at room temperature for 24 h, the reaction mixture is diluted with methylene chloride and washed with water; the organic phase is dried and concentrated and the residue is recrystallised from ethanol. In this way 4'-chlorobiphenyl-4-carboxylic acid N'-(2,6-difluorobenzoyl)-hydrazide having a melting point of 261-265°C is obtained. c) At 110°C, 6.97 g of phosphorus pentachloride are introduced into 30 ml of dichloro- benzene and, in the course of 15 min., 2.88 g of 4'-chlorobiphenyl-4-carboxylic acid N'-(2,6- difluorobenzoyl)-hydrazide are added in portions thereto. After then being stirred for 2.5 h, the reaction mixture is concentrated and the residue is suspended in methanol and filtered. In this way N-[chloro-(4'-chlorobiphenyl-4-yl)-methylidene]-N'-[chloro-(2,6-difluorophenyl)- methylidenej-hydrazine having a melting point of 149-161 °C is obtained in the form of an E/Z mixture. d) 2.2 g of N-[chloro-(4'-chlorobiphenyl-4-yl)-methylidene]-N'-[chloro-(2,6-difluorophenyl)- methylidenej-hydrazine are added, in portions, at 15-20°C to 22 ml of hydrazine (0.5 molar) in THF and stirring is carried out at room temperature for 45 h. The reaction mixture is then poured into water and the precipitated crystals are filtered and washed with water. Recrystal- lisation from ethyl acetate yields the title compound having a melting point of 242-248°C. Example 2: 3-(4'-Chlorobiphenyl-4-yl)-6-(2,6-difluorophenyl)-π .2.4.51tetrazine At 40°C, 500 mg of 3-(4'-chlorobiphenyl-4-yl)-6-(2,6-difluorophenyl)-1,2-dihydro[1, 2,4,5]- tetrazine are introduced into 12 ml of acetic acid and 0.25 ml of water; 90 mg of sodium nitrite are added and stirring is carried out at room temperature for 5 h. After filtration, the crude product is suspended first in diethyl ether and then in ethyl acetate. In this way, the title compound having a melting point of 230-232°C is obtained. Example 3: 3-(4'-Trifluoromethylbiphenyl-4-yl)-6-(2,6-difluorophenyl)-f 1 ,2,4,51tetrazine At room temperature, 0.5 g of 3-(4-bromophenyl)-6-(2,6-difluorophenyl)-[1,2,4,5]tetrazine, 0.3 g of 4-trifluoromethylphenylboronic acid and 0.44 g of caesium fluoride are placed in 11 ml of dimethoxyethane and 11 ml of methanol. After the addition of 19.3 mg of palladium acetate and 54.1 mg of tri-o-tolylphosphine, the reaction mixture is stirred at 50°C for 3 h and is then poured into water and extracted with ethyl acetate; the organic phase is dried and concentrated. The residue is stirred with 20 ml of diethyl ether and filtered off. In this way, the title compound having a melting point of 251-252°C is obtained. Analogously to the procedures described above it is also possible to prepare the substances listed in the following Tables 1 to 4. The melting point values are given in °C.

Control of adult fleas in cats by means of pour-on application In order to determine the effectiveness of the test compounds against fully grown fleas, four groups each of two cats are used. Each cat is infested with 100 cat fleas [Ctenocephalides felis (Bouche)] and treated with 20 mg of active ingredient per kg body weight. The treatment is effected by applying the formulation to a locally defined area on the back of the cat's neck. One group is infested with fleas but is treated only with a placebo, that is to say a formulation without active ingredient, and serves as control. Another group is treated with nitenpyram as comparison substance; the two remaining groups are treated with the test compounds. Evaluation is carried out in each case by combing surviving fleas out of the animal's coat, counting them and comparing the number counted with the number of fleas in the control group and in the group treated with nitenpyram. The procedure in detail is as follows: each cat is infested with 100 fleas immediately after treatment on day 0. On day +1 , each animal is combed and the number of surviving fleas is determined; the surviving fleas are then replaced on the same cat and after 24 hours the combing and evaluation are repeated. The fleas still surviving after those 24 hours are not returned to the cat. The described procedure is then repeated on days +3, +7, +9, +14, +21 , +28, +35, +42 and +49 and in this way the effectiveness and duration of action are determined. On every day on which surviving fleas are combed out, a blood sample of about 2.7 ml is taken from each cat - with the exception of the control group - and the content of active ingredient is measured. The effectiveness is determined in accordance with the following formula: number of living fleas minus number of living fleas per control animal per test animal % effectiveness = * 100 number of living fleas per control animal It is shown that the compounds of formula (I) according to the invention achieve excellent long-term action in comparison with nitenpyram. In dogs the test proceeds in an entirely analogous manner. Similar effects are also observed when the substances are administered not in the form of a pour-on but in the form of an injection solution. 3.13. Control of adult fleas in cats by means of subcutaneous injection In order to determine the effectiveness of the test compounds against fully grown fleas, four groups each of two cats aged from 1.5 to 4 years are used. Each cat is infested with 100 cat fleas [Ctenocephalides felis (Bouche)] and treated with 20 mg of active ingredient per kg body weight. The treatment is effected by subcutaneous injection of a solution of the active ingredient behind the left shoulder blade. One group is infested with fleas but is treated only with a placebo, that is to say a formulation without active ingredient, and serves as control. Another group is treated with nitenpyram as comparison substance; the two remaining groups are treated with the test compounds. The evaluation is in each case carried out analogously to the preceding Example. It is shown that after subcutaneous injection the compounds of formula (I) according to the invention achieve excellent long-term action in comparison with nitenpyram. The analogous test with dogs gives comparable results.
