Arthropod repellant

The present invention relates to the new use of p-hydroxyphenylacetic acid, by itself or in a mixture with other chemical compounds, for reducing the repellency of insecticides in the control of cockroaches, and to cockroach control compositions which comprise these mixtures, details being found in the description.

Para-hydroxyphenylacetic acid for reducing the repellency of insecticides

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,

Insect- and mite-repelling method

It has been found that the substituted .alpha.,.omega.-amino-alcohol derivatives, some of which are known, of the formula I ##STR1## in which X represents hydrogen, COR.sup.11, COOR.sup.12 or R.sup.13,

Agents for repelling insects and mites

A insect and mite repellent composition in which the active ingredient is an acylated .alpha.-amine acid ester derivative of the formula ##STR1## in which R.sup.1 stands for hydrogen or for an optionally substituted alkyl, alkenyl or alkinyl radical,

Repelling insects and mites with acylated .alpha.,.omega., aminoalcohol derivatives of the formula ##STR1## in which X represents hydrogen, COR.sup.11, COOR.sup.12 or R.sup.13,

Substituted .alpha.,.omega.-aminoalcohol derivatives

Repelling insects and mites with acylated .alpha.,.omega.-aminoalcohol derivatives of the formula ##STR1## in which X represents hydrogen, COR.sup.11, COOR.sup.12 or R.sup.13,

Acylated aminoalcohols for repelling insects and mites
