A compound of the formula (I) where, for example, W, X and Y are each CH; R1 and R6 together with the adjacent nitrogen forms a 3 to 10-membered saturated ring, wherein the ring may contain, in addition to the nitrogen and carbon ring members, 1, 2 or 3 heteroatoms and/or heteroatom groups as ring members, independently of one another, selected from the group consisting of sulfur, CO, SO, SO2 and N—R7 and/or the ring may carry 1, 2 or 3 radicals, independently of one another, each selected, for example, from the group consisting of halogen, cyano, nitro, amino, and C1-C6-alkyl. R2 is, for example, halogen, C1-C6-alkyl, C1-C6-haloalkyl, C1-C6-alkoxy, C1-C6-haloalkoxy or C1-C6-alkoxy-C1-C6-alkoxy, and R7 is for example, R10C(═O), C1-C6 alkyl or C1-C6-haloalkyl; and/or salts thereof; and their use as pesticidal agents.
