An N-substituted benzamide of the formula <IMAGE> (I) in which R1 represents hydrogen or alkyl, R2 represents halogenoalkyl with more than one carbon atom, or represents cycloalkyl which is substituted by halogen or halogenoalkyl and R3, R4, R5, R6 and R7 are identical or different and represent hydrogen, halogen, nitro, alkyl, halogenoalkyl, halogenoalkoxy or halogenoalkylthio, or represent the radical-CONR1R2. The N-substituted benzamides are active as insecticides and nematicides and can be prepared by reacting a benzoyl halide of the formula (II) <IMAGE> (II) in which R8, R9, R10, R11 and R12 are identical or different and represent hydrogen, halogen, nitro, alkyl, halogenoalkyl, halogenoalkoxy or halogenoalkylthio, or represent the radical -CO-Hal and Hal represents halogen, with an amine of the formula (III) HNR1R2 (III) in which R1 and R2 have the abovementioned meanings, or with corresponding hydrohalides.
