There are provided new substituted pyrazolines of the general formula (I) ##STR1## in which R.sup.1 represents optionally substituted phenyl and either R.sup.2 represents a radical of the formula --CO--R.sup.7, --COOR.sup.7 or --SO.sub.2 --R.sup.7, where R.sup.7 has the meaning given in the text of the application, and R.sup.3 represents hydrogen, alkyl or halogenoalkyl or R.sup.2 and R.sup.3 together with the nitrogen atom to which they are bonded represent a heterocycle R.sup.4 represents hydrogen, alkyl, halogenoalkyl, halogenoalkylthio, halogen, alkoxycarbonyl or in each case optionally substituted cycloalkyl or aryl, R.sup.5 represents hydrogen or alkyl, R.sup.6 represents in each case optionally substituted alkyl, cycloalkyl or 3,4-disubstituted phenyl and X represents oxygen or sulphur. The new substituted pyrazolines have a highly pronounced activity against animal pests, in particular against insects.
