A urea derivative of the general formula,
(wherein X is a halogen), which has higher insecticidal activity than known similar compounds with lowered toxicity to mammals and fishes. The derivative can be produced by reacting 2-fluoro-4-halo- aniline with 2,6-difluorobenzoyl isocyanate or reacting 2-fluoro-4-halo-phenylisocyanate with 2,6-difluorobenzamide.
