Disclosed are an oxazoline compound, a synthesis method therefor and an application thereof. The oxazoline compound has a structure represented by formula (I), wherein in the formula (I), R is selected from groups represented by formula (I-1), formula (I-2), and formula (I-3), where an oxazoline derivative having a novel molecular structure is obtained by introducing a nitrogen heterocycle, an ether bond or a sulfonate structure into the oxazoline compound. The oxazoline derivative is useful in the field of agricultural protection, and has higher acaricidal activity than etoxazole, can inhibit the synthesis of chitin from mites, and can effectively control the embryogenesis and development of eggs of Tetranychus cinnabarinus, as well as the ecdysis process from larvae to adults, and therefore has a significant effect in killing mite eggs and larvae.
