Compounds of structure (I), the corresponding N-oxides and agriculturally acceptable salts, are disclosed as effective insecticides, in which Q is selected from hydrogen, hydroxy, and fluorine; R is selected from a heteroaryl having 5 or 6 ring atoms, and (II) in which V is hydrogen, halogen, alkyl, haloalkyl, or alkoxy; W and X are independently selected from a wide variety of substituents, Y and Z are independently selected from hydrogen and alkoxy; W and X taken together may be -OCH2CH2O-, -CH2C(CH3)2O-, or -OC(CH3)2O-; R?1 and R2¿ are independently selected from phenyl substituted with halogen, alkyl, haloalkyl, haloalkoxy, alkylsulfonyloxy, and haloalkylsulfonyloxy; and n is 1, 2 or 3; with the proviso that each aliphatic moiety contains not more than 6 carbon atoms, halogen means chlorine or fluorine, and each alkyl substituent on an amino nitrogen contains 1 to 3 carbon atoms. The manner of preparing these compounds is also disclosed.
