<p>Pesticidally active N-iminopyridinium ylide compounds of formula (I) wherein A is CR4R5 or C=O; X is O or S; Y is O or S; Het is a 5- or 6-membered carbon-bound saturated, unsaturated or aromatic heterocycle, having 1, 2 or 3 heteroatoms selected from O, S and N; said Het can be mono- di- or trisubstituted by substituents selected from the group consisting of halogen, C1-C4-alkyl and C1-C4-haloalkyl; R1, R2, and R3 are independently from one another selected from hydrogen, halogen, C1-C4-alkyl, C1-C4-haloalkyl, C1-C4-alkoxy, C1-C4-haloalkoxy, cyano and nitro; and R4 and R5 are independently from one another selected from hydrogen, halogen and C1-C4-alkyl; or R4 and R5 together with the carbon to which they are each attached form a 3 to 6 membered cycloalkyi group; are useful for controlling animal pests and can be prepared in a manner known per se.</p> |
