This invention provides compounds of Formula I, their N-oxides and agriculturally suitable salts wherein A and B are independently O or S; J is an optionally substituted 5- or 6-memebered nonaromatic heterocyclic ring; K is taken together with the two contiguous linking carbon atoms to form a phenyl ring or a 5- or 6-membered heteroaromatic ring, each ring optionally substituted; and R.sub.1, R.sub.2, and R.sub.3 are as defined in the disclosure. Also disclosed are methods for controlling an invertebrate pest comprising contacting the invertebrate pest or its environment with a biologically effective amount of a compound of Formula I, an N-oxide thereof or a suitable salt of the compound (e.g., as a composition described herein). This invention also pertains to a composition for controlling an invertebrate pest comprising a biologically effective amount of a compound of Formula I, an N-oxide thereof or a suitable salt of the compound and at least one additional component selected from the group consisting of surfactants, solid diluents and liquid diluents. ##STR00001##
