    摘要: Insecticidally and acaricidally active novel 1-aryl-3-tert.-butyl-pyrazoles of the formula ##STR1## in which R.sup.1 represents nitro or halogen,R.sup.2 represents halogen or the --NR.sup.3 R.sup.4 group, and also may represent hydrogen when R.sup.1 denotes halogen,whereR.sup.3 represents hydrogen, in each case optionally substituted alkyl, alkenyl or alkinyl, and in each case optionally substituted cycloalkyl or cycloalkylalkyl andR.sup.4, independently of R.sup.3, represents the same radicals as R.sup.3l , and, in addition, a ##STR2## radical, where X represents oxygen or sulphur andR.sup.5 represents hydrogen, alkyl, alkenyl, alkinyl, halogenoalkyl, alkoxyalkyl, alkylthioalkyl, optionally substituted cycloalkyl, optionally substituted aryl, alkoxy, alkylthio, optionally substituted aryloxy, optionally substituted arylthio, alkylamino, dialkylamino or optionally substituted arylamino; andAr represents optionally substituted phenyl, apart from dinitrophenyl, or optionally substituted pyridyl. Intermediates where R.sup.1 is replaced by hydrogen are also new and are also pesticidally active.
