Abstract

Insecticidally and acarididally active 1-arylpyrazoles of the formula ##STR1## in which R.sup.1 represents hydrogen, alkyl or halogen alkyl, PA1 R.sup.2 represents alkyl, alkenyl, alkinyl, cycloalkyl, halogenoalkyl, halogenoalkenyl, alkoxyalkyl, alkylthioalkyl, alkylsulphinylalkyl, alkylsulphonylalkyl, optionally substituted aralkyl or optionally substituted aryl, PA1 R.sup.3 represents alkyl, alkenyl, alkinyl, halogenoalkyl, halogenoalkenyl, alkoxyalkyl, alkylthioalkyl, cycloalkyl or optionally substituted aralkyl, PA1 R.sup.4 represents alkyl, alkenyl, alkinyl, halogenoalkyl, halogenoalkenyl, alkoxyalkyl, alkylthioalkyl, cycloalkyl or optionally substituted aralkyl, and, in addition, also represents hydrogen in the case where R.sup.3 does not simultaneously represent unsubstituted alkyl, or PA1 R.sup.3 and R.sup.4, together with the nitrogen atom to which they are bound, represent a saturated heterocycle, which can optionally contain further heteroatoms, PA1 Ar represents in each case optionally substituted phenyl or pyridyl, and PA1 n represents a number 0, 1 or 2.
