• in which the substituents have the following meanings:
• X is halogen, C1-C4-alkyl, C1-C4-haloalkyl, C1-C8-alkoxy, C1-C4-haloalkoxy and —O—C(Ra,Rb)—C≡C—Rc;
• Ra,Rb independently of one another are hydrogen and C1-C6-alkyl;
• Rc is hydrogen, C1-C8-alkyl, C3-C8-cycloalkyl and phenyl which can be substituted by halogen, cyano, nitro, CF3, C1-C4-alkyl and/or C1-C4-alkoxy;
• m,n independently of one another are 1 to 4, it being possible for the radicals X and Y to be different if m or n is greater than 1;
• Y is halogen, nitro, cyano, C1-C4-alkyl, CF3, C1-C4-alkoxy and phenyl;
• R1, R2 independently of one another are hydrogen, halogen, Cl-C4-alkyl, Cl-C4-alkoxy, Cl-C4-haloalkoxy and CF3;
• R3,R4,R5,R6 independently of one another are hydrogen, C1-C4-alkyl and C1-C4-alkoxy or
• R3 and R4 together form a cyclopropyl ring, it being possible for the C—R5- and C—R6-bonds to be in the E- or Z-position relative to each other;
