Insecticidal bicyclooxyphenyl ureas

A composition of the formula:

• ##STR28## wherein M represents a monocyclic aromatic ring system or a monocyclic heterocyclic ring system containing up to 2 nitrogen atoms, and wherein the ring can contain up to four X substituents wherein each X individually can be halogen, nitro, cyano, or alkyl, polyhaloalkyl, alkoxy or polyhaloalkoxy of from 1 to 3 carbon atoms;
• Z and Z.sup.1 individually are hydrogen or alkyl of from 1 to 8 carbon atoms, or alkyl of from 1 to 8 carbon atoms which is substituted with at least one of halogen, hydroxyl or alkoxy;
• Y individually represents halogen, or alkyl, polyhaloalkyl, alkoxy or polyhaloalkoxy of from 1 to 3 carbon atoms, and n has a value of from 0 to 4;
• B is a bicyclic fused ring system which is attached to the oxygen through a carbocyclic ring and wherein (a) at least one ring is a six-membered, unsaturated carbocyclic ring which can contain up to two R and R.sup.1 substituents wherein R and R.sup.1 can be halogen, nitro, cyano, amino, formamido, formamidino, phenylsulfenyl, phenylsulfinyl, phenylsulfonyl, phenylsulfamido wherein the phenyl ring optionally may be substituted with one or more halogen, nitro, or alkyl, polyhaloalkyl, alkoxy or polyhaloalkoxy of from 1 to 3 carbon atoms, or R and R.sup.1 individually are alkyl, alkoxy, polyhaloalkyl, polyhaloalkoxy, alkenyloxy, polyhaloalkenyloxy, alkynyloxy, polyhaloalkynyloxy, alkylsulfenyl, poyhaloalkylsulfenyl, alkylsulfinyl, polyhaloalkylsulfinyl, alkylsulfonyl, polyhaloalkylsulfonyl, mono- or di-alkylsulfamido, mono- or di-alkylamino, alkylcarbonylamino, alkoxycarbonylamino, mono- or di-alkylaminocarbonyloxy of up to 6 carbon atoms, and (b) the second ring, hereinafter also referred to as A, when it is not a five or six-membered carbocyclic can be a five or six-membered saturated or unsaturated hetero-cyclic ring which can contain in any combination carbonyl or one or two oxygen or sulfur, and up to two R.sup.2 and R.sup.3 substituents attached to unsaturated ring carbon atoms wherein R.sup.2 and R.sup.3 individually can be halogen, nitro, cyano, or alkyl, polyhaloalkyl, alkoxy, polyhaloalkoxy, alkylthio, arylthio, alkylsulfinyl, arylsulfinyl, alkylsulfonyl, arylsulfonyl, alkylsulfamido, arylsulfamido, alkoxycarbonylamino, or alkylcarbonylamino of from 1 to 6 carbon atoms, or can contain up to two R.sup.4 and R.sup.5 substituents attached to saturated carbon atoms of the chain wherein R.sup.4 and R.sup.5 individually can be alkyl or polyhaloalkyl of from 1 to 6 carbon atoms;
• with the proviso that when B is a naphthyl group it is attached through an oxygen to the number 4 carbon atom of the phenyl group, and with the further proviso that (a) if X is halogen and is mono or disubstituted in the ortho position of a benzoyl ring (b) if Z and Z.sup.1, are hydrogen (c) if no more than 2 of R, R.sup.1, R.sup.2 or R.sup.3 are hydrogen, chloro or bromo, and (d) if Y represents chloro, then n has a value of at least 2.
