Abstract

Insect- and mite-repelling new morpholinoureas of the formula (I) ##STR1## in which the radicals R.sup.1 to R.sup.8 can be identical or different and represent hydrogen, optionally substituted alkyl, optionally substituted alkenyl, optionally substituted alkynyl, optionally substituted cycloalkyl or optionally substituted phenyl, or where the radicals R.sup.1 and R.sup.4 and/or R.sup.5 and R.sup.8 in each case together form a carbocyclic ring, PA1 R.sup.9 represents optionally substituted alkyl, optionally substituted alkenyl, optionally substituted alkynyl, optionally substituted cycloalkyl or optionally substituted benzyl, and PA1 R.sup.10 represents hydrogen, optionally substituted alkyl, optionally substituted alkenyl, optionally substituted benzyl or optionally substituted cycloalkyl, or where R.sup.9 and R.sup.10 together represent an optionally substituted polyalkylene radical which is optionally interrupted by hetero atoms.
