Novel N-containing heterocyclic ring-substituted O-arylphosphate derivatives, the preparation thereof and insecticides acaricides and nematicides containing said derivatives are provided. The O-arylphosphate derivatives have the general formula: ##STR1## wherein A is --CH or nitrogen, X is hydrogen, a halogen or trifluoromethyl; Y is oxygen, S(O)n (wherein n is an integer of from 0 to 2) or NR.sup.2 (wherein R.sup.2 is hydrogen or a lower alkyl); Z is oxygen or sulfur; R and R.sup.1 independently are a lower alkoxy or lower alkylthiol; and B is hydrogen, a halogen or a lower alkyl. The O-arylphosphate derivatives have an excellent insecticidal acaricidal and nematocidal action.

N-Containing heterocyclic ring-substituted O-arylphosphate derivatives,

This invention relates to a heterocyclic ether or thioether linkage containing urea compounds of the following formula I: ##STR1## wherein B denotes an oxygen atom or a sulfur atom, A denotes CH or a nitrogen atom, X.sup.1 and X.sup.2 denote independently of each other hydrogen atom, halogen atom, trifluoromethyl group or nitro group, Y and Z denote independently of each other hydrogen atom or halogen atom, and P and Q denote independently of each other hydrogen atom, halogen atom, alkoxyl group or alkyl group, a process for producing the same and an insecticide containing the same.

Benzoazine ether or thioether linkage containing urea compounds, process

An aniline derivative represented by the formula (I): ##STR1## wherein A denotes CH or nitrogen atom; B denotes oxygen atom or sulfur atom; X.sup.1 and X.sup.2, independently of each other, denote hydrogen atom, halogen atom, trifluoromethyl group or nitro group; Y and Z, independently of each other, denote hydrogen atom or halogen atom, and a process for producing the same.
