A novel 4-heterocyclic ring-substituted pyrimidine derivative represented by formula (1), which is useful as a pest organism control agent. (In formula (1), R1 and R2 independently represent a hydrogen atom, a halogen atom, or the like; R3 and R4 independently represent a hydrogen atom, or the like; n represents a numeral value of 0 to 5; Q represents a linear or branched alkyl group having 1 to 6 carbon atoms, or the like; and A represents a 5-membered cyclic structure represented by formula (2), or the like.) (In formula (2), V and X independently represent an oxygen atom, or the like; and R5, R6 and R7 independently represent a hydrogen atom, or the like.) |
