Hydrazonoacetic acid amides and the use thereof as pesticides

Process for preparing compounds of the formula ##STR11## in which A represents an optionally substituted alkylene,

• Q represents oxygen or sulphur,
• R.sup.1 represents respectively optionally substituted cycloalkyl, cycloalkenyl, or aryl,
• R.sup.1, R.sup.3 and R.sup.4 are identical or different and each represent hydrogen or respectively optionally substituted alkyl,
• R.sup.5 represents respectively optionally substituted cycloalkyl, cycloalkenyl, or aryl,
• characterized in that carboxylic acid derivatives of the general formula (II) ##STR12## in which R.sup.2, R.sup.2, R.sup.3 and Q are each as defined above and
• T represents hydroxyl, halogen or alkoxy
• are reacted with an amine of the general formula (III) ##STR13## in which R.sup.4, R.sup.5 and A are each as defined above
• or with a hydrogen halide thereof
• optionally in the presence of an acid acceptor, optionally in the presence of a condensing agent and optionally in the presence of a diluent.
