CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This is a divisional of application Ser. No. 10/225,354, filed Aug. 22, 2002, now allowed, incorporated by reference herein in its entirety and relied upon, which claims the priority of German Application Nos. 10141339.4 of Aug. 23, 2001 and 10217697.3 of Apr. 20, 2002. [0002] The invention relates to the use of substituted aryl- and heteroarylpropargylamines as pesticides, in particular against harmful arthropods and helminths. [0003] In EP-A-0 041 324, 1-[3-(3,5-bistrifluoromethylphenyl)-2-propynyl]4-tert-butylpiperidine is described as rodenticide. Similar compounds in which the tertiary butyl radical is substituted are described in DE-A-3 504 412. Further compounds of this type in which the butyl radical is replaced by other alkyl radicals are described in 1987 BCPC mono. No. 37 Stored Products Pest Control, p. 125. In addition, there are further publications in which compounds are mentioned in which aryl radicals are attached via propargyl to nitrogen-containing heterocycles. [0004] Surprisingly, it has now been found that compounds of this type have insecticidal, acaricidal and helminthicidal action. Some of the compounds are novel. [0005] The invention provides a method for controlling harmful arthropods, such as insects and Acarina, and helminths, such as parasites of animals and plant-damaging nematodes, which comprises applying to these pests or to the plants or animals, areas or substrates infected by them an effective amount of a compound of the formula (I) where [0006] a) R.sup.1 is heteroaryl or aryl, unsubstituted or mono- or polysubstituted by identical or different radicals, [0007] b) A is a group CR.sup.4R.sup.5 or C.dbd.O, where [0008] R.sup.4 is hydrogen, halogen or alkyl; [0009] R.sup.5 is hydrogen, halogen or a substituted or unsubstituted hydrocarbon radical; [0010] c) R.sup.2 and R.sup.3 together with the nitrogen atom to which they are attached form N-heteroaryl or N-heterocyclyl, unsubstituted or mono- or polysubstituted by identical or different radicals, if appropriate also as N-oxide and/or salt. [0011] The invention also provides the use of compounds of the formula (I) for controlling arthropods, such as insects and Acarina, and helminths, such as parasites of animals and plant-damaging nematodes. [0012] Many of the compounds of the formula (I) are novel, and the invention embraces all novel compounds of the formula (I), in particular those in which [0013] a) R.sup.1 is heteroaryl which is unsubstituted or mono- or polysubstituted by identical or different radicals or is aryl which is mono- or polysubstituted by identical or different radicals, [0014] b) A is as defined above; [0015] c) R.sup.2 and R.sup.3 together with the nitrogen atom to which they are attached form a piperidine which is unsubstituted or mono- or polysubstituted by identical or different radicals, with the proviso that, if R.sup.2 and R.sup.3 together with the nitrogen atom to which they are attached form a piperidine radical which is unsubstituted or substituted in the 4-position by unsubstituted or substituted alkyl, R.sup.1 is not 3,5-bistrifluoromethylphenyl. [0016] In the above formula, a hydrocarbon radical is a straight-chain, branched or cyclic saturated, partially saturated, unsaturated or aromatic organic radical having preferably 1 to 20 carbon atoms, for example alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, cycloalkynyl, aryl or benzyl. This definition also applies to composite terms, such as cycloalkylalkenyl, cycloalkynylalkyl and arylalkynyl. If a hydrocarbon radical contains additional heteroatoms, these can in principle, i.e. the chemical structure permitting, be located in any position of the hydrocarbon radical. [0017] In formula (I) and all subsequent formulae, carbon-containing radicals in the form of a chain, such as alkyl, alkoxy, haloalkyl, haloalkoxy, alkylamino and alkylthio, and the corresponding radicals which are unsaturated and/or substituted in the carbon skeleton, such as alkenyl and alkynyl, can in each case be straight-chain or branched. Unless indicated otherwise, in these radicals the lower carbon skeletons, preferably those having 1 to 6 carbon atoms or, in the case of unsaturated groups, 2 to 4 carbon atoms, are preferred. [0018] Alkyl radicals, also in composite groups such as alkoxy, haloalkyl, etc., are, for example, methyl, ethyl, n- or isopropyl, n-, iso-, t- or 2-butyl, pentyl radicals, hexyl radicals, such as n-hexyl, isohexyl and 1,3-dimethylbutyl, heptyl radicals, such as n-heptyl, 1-methylhexyl, 1,4-dimethylpentyl, and benzyl; alkenyl and alkynyl radicals, also in the composite groups, have the meaning of the unsaturated radicals which are possible and correspond to the alkyl radicals; alkenyl is, for example, allyl, 1-methylprop-2-en-1-yl, 2-methyl-prop-2-en-1-yl, but-2-en-1-yl, but-3-en-1-yl, 1-methyl-but-3-en-1-yl and 1-methyl-but-2-en-1-yl; alkynyl is, for example, propargyl, but-2-yn-1-yl, but-3-yn-1-yl, 1-methyl-but-3-yn-1-yl. The multiple bond can be located in any position of the unsaturated radical. [0019] Cycloalkyl is a carbocyclic saturated ring system having preferably three to eight carbon atoms, for example cyclopropyl, cyclobutyl, cyclopentyl or cyclohexyl. Analogously, cycloalkenyl is a monocyclic alkenyl group having three to eight carbon ring members, for example cyclopropenyl, cyclobutenyl, cyclopentenyl and cyclohexenyl, where the double bond can be located in any position. [0020] In the case of composite radicals, such as cycloalkylalkenyl, the first-mentioned radical can be located in any position of the second-mentioned radical. [0021] In the case of an amino group which is doubly substituted, such as dialkylamino, these two substituents can be identical or different. [0022] Halogen is fluorine, chlorine, bromine or iodine. Haloalkyl, -alkenyl and -alkynyl, etc., is alkyl, alkenyl and alkynyl, respectively, which is partially or fully substituted by halogen, preferably by fluorine, chlorine and/or bromine, in particular by fluorine or chlorine, for example CF.sub.3, CHF.sub.2, CH.sub.2F, CF.sub.2CF.sub.3, CHClCH.sub.2F, CCl.sub.3, CCl.sub.2F, CClF.sub.2, CHCl.sub.2, CH.sub.2CH.sub.2Cl; haloalkoxy is, for example, OCF.sub.3, OCHF.sub.2, OCH.sub.2F, OCF.sub.2CF.sub.3, OCH.sub.2CF.sub.3 and OCH.sub.2CH.sub.2Cl; this applies correspondingly to other halogen-substituted radicals. [0023] The term "heterocyclyl" is to be understood as meaning a saturated or partially unsaturated mono- or polycyclic ring system having preferably 3 to 14 ring members which contains one or more, preferably one to three, heteroatoms, preferably from a group consisting of oxygen, nitrogen ("N-heterocyclyl") and sulfur. If chemically possible, the point of attachment can be in any position of the heterocycle. Examples are oxiranyl, aziridinyl, tetrahydrofuranyl, tetrahydrothienyl, pyrrolidinyl, isoxazolidinyl, isothioazolidinyl, pyrazolidinyl, oxazolidinyl, thiazolidinyl, imidazolidinyl, 1,2,4-oxadiazolidinyl, 1,2,4-thiadiazolidinyl, 1,2,4-triazolidin-3-yl, 1,3,4-thiadiazolidin-2-yl, 1,3,4-triazolidin-1-yl, 1,3,4-triazolidin-2-yl, 2,3-dihydrofuryl, 2,5-dihydrofuryl, 2,3-dihydrothienyl, 2,5-dihydrothienyl, 2,3-dihydropyrrolyl, 2,5-dihydropyrrolyl, 2,3-dihydroisoxazolyl, 4,5-dihydroisoxazolyl, 2,5-dihydroisothiazolyl, 2,3-dihydropyrazolyl, 4,5-dihydropyrazolyl, 2,5-dihydropyrazolyl, 2,3-dihydrooxazolyl, 4,5-dihydrooxazolyl, 2,5-dihydrooxazolyl, 2,3-dihydrothiazolyl, 4,5-dihydrothiazolyl, 2,5-dihydrothiazolyl, 2,3-dihydroimidazolyl, 4,5-dihydroimidazolyl, 2,5-dihydroimidazolyl, morpholinyl, piperidinyl, piperazinyl, tetrahydropyridazinyl, tetrahydropyrimidinyl, tetrahydropyrazinyl, 1,3,5-tetrahydrotriazinyl, 1,2,4-tetrahydrotriazin-1-yl, 1,2,4-tetrahydrotriazin-3-yl, 1,3-dihydrooxazinyl, 1,3-dithian-2-yl, tetrahydropyranyl, 1,3-dioxolan-2-yl, 3,4,5,6-tetrahydropyridin-2-yl, 1,2,5,6-tetrahydropyridin-1-yl, 1,2,3,4-tetrahydropyridin-1-yl, 1,2-dihydropyridin-1-yl, 1,4-dihydropyridin-1-yl, 4H-1,3-thiazinyl, 4H-3,1-benzothiazin-2-yl, 1,3-dithian-2-yl, 1,1-dioxo-2,3,4,5-tetrahydrothien-2-yl, 2H-1,4-benzothiazinyl, 1,3-dihydrooxazin-2-yl, hexahydroazepin-1-yl, homopiperazin-1-yl, 1,2,3,4-tetrahydroquinolin-1-yl, decahydroquinolin-1-yl, 1,2,3,4-tetrahydroisoquinolin-1-yl, decahydroisoquinolin-1-yl, 1,3,3-trimethyl-6-azabicyclo[3.2.1]octan-6-yl, 2,5-diazabicyclo[2.2.1]heptan-2-yl, 2-aza-5-oxabicyclo[2.2.1]heptan-2-yl, 2-aza-5-thiabicyclo[2.2.1]heptan-2-yl, 2-methyl-2,5-diazabicyclo[2.2.1]heptan-5-yl, 2-benzyl-2,5-diazabicyclo[2.2.1]heptan-5-yl, 4-azatricyclo[4.3.1.1 (3,8)]undecan-5-on-4-yl. [0024] Aryl is an aromatic mono- or polycyclic hydrocarbon radical having preferably 6 to 14, particularly preferably 6 to 12, carbon atoms, for example, phenyl, naphthyl, biphenyl and phenanthryl. [0025] Heteroaryl is an aromatic mono-, bi- or tricyclic ring system having preferably 5 to 14 ring members which, in addition to carbon ring members, contains one to four nitrogen atoms or one to three nitrogen atoms ("N-heteroaryl") and one oxygen or one sulfur atom or one oxygen or one sulfur atom. Examples of 5-membered heteroaryl are 1-pyrrolyl, 2-pyrrolyl, 3-pyrrolyl, 1-pyrazolyl, 3-pyrazolyl, 4-pyrazolyl, 5-pyrazolyl, 1-imidazolyl, 2-imidazolyl, 4-imidazolyl, 1,2,4-triazol-3-yl, 1,3,4-triazol-2-yl, 1,2,3-triazol-1-yl, 2-furyl, 3-furyl, 2-thienyl, 3-thienyl, 3-isoxazolyl, 4-isoxazolyl, 5-isoxazolyl, 3-isothiazolyl, 4-isothiazolyl, 5-isothiazolyl, 2-oxazolyl, 4-oxazolyl, 5-oxazolyl, 2-thiazolyl, 4-thiazolyl, 5-thiazolyl, 1-imidazolyl, 2-imidazolyl, 1,2,4-oxadiazol-3-yl, 1,2,4-oxadiazol-5-yl, 1,2,4-thiadiazol-3-yl, 1,2,4-thiadiazol-5-yl, 1,3,4-oxadiazol-2-yl, 1,3,4-thiadiazol-2-yl.

[0026] Depending on the nature and the attachment of the substituents, the compounds of the formula (I) can be present as stereoisomers. If, for example, one or more alkenyl groups are present, diastereomers may occur. If, for example, one or more asymmetrically substituted carbon atoms are present, enantiomers and diastereomers may occur. From the mixtures obtained in the preparation, stereoisomers can be obtained by customary separation methods, for example by chromatographic separation procedures. It is also possible to selectively prepare stereoisomers by using stereoselective reactions and employing optically active starting materials and/or auxiliaries. The invention also relates to all stereoisomers and mixtures thereof which are embraced by formula (I) but not specifically defined. [0027] The term "partially or fully halogenated" is meant to express that in the groups thus characterized some or all of the hydrogen atoms may be replaced by identical or different halogen atoms as mentioned above. [0028] If a group is polysubstituted, this is meant to be understood such that, when combining the different substituents, the general principles of the synthesis of chemical compounds are observed, i.e. that the formation of compounds is avoided of which the person skilled in the art knows that they are chemically unstable or impossible. [0029] The symbols and indices of the formula (I) are preferably as defined below: [0030] R.sup.1 is an aryl or heteroaryl radical which is unsubstituted or mono- or polysubstituted by identical or
