Compounds of Formula (I), and their N-oxides and suitable slats, are disclosed which are useful as invertebrate pest control agents, wherein A and B are independently O or S; E is C or N; J is a phenyl ring, a naphthyl ring system, a 5- or 6-membered heteroaromatic ring or an aromatic 8-, 9- or 10-membered fused heterobicyclic ring system wherein each ring or ring system is optionally substituted with 1 to 4 R.sup.5; K is taken together with the two contiguous linking carbon atoms to form a 5- or 6-membered nanoaromatic carbocyclic or heterocyclic ring optionally including one or two ring members selected from the group consisting of C(.dbd.O), SO or S(O).sub.2, each ring optionally substituted with 1 to 4 R.sup.4; and R.sup.1, R.sup.2, R.sup.3, R.sup.4 and R.sup.5 are as defined in the disclosure. Also disclosed are compositions containing the compounds of Formula (I) and a method for controlling an invertebrate pests which involves contacting the pest or its environment with an effective amount of a compound of Formula (I) ##STR00001##
