An aromatic compound of the formula:
 wherein R¹ and R² are, the same or different, a hydrogen atom, a halogen atom or a methyl group with the proviso that either one of R¹ or R² is a hydrogen atom; R³ is a hydrogen atom or a methyl group; and R⁴ is a halogen atom, a C₁-C₂ alkyl group or a C₁-C₂ haloalkyl group, which is useful for control of insect pests.
                            式中的芳香族化合物:
 其中 R¹ 和 R² 是相同或不同的氢原子、卤素原子或甲基,但 R¹ 或 R² 之一是氢原子;R³ 是氢原子或甲基;R⁴ 是卤素原子、C₁-C₂ 烷基或 C₁-C₂ 卤代烷基,可用于防治害虫。
