N-Containing heterocyclic ring-substituted O-arylphosphate derivatives, preparation thereof, and insecticides, acaricides and nematocides containing said derivatives

摘要

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.
