A study of the bioactivity of2 kinds of spiro enol ether analogues against Pieris rapae slowed that AFC5o in choice test of compounds
No. 12 and No.20 against the 4th instar larvae of P. rapae within 24 h was 398.88 mg/L and 280.54mg/L, respectively. The two compounds significantly reduced the weight of the larvae and the pupae of the pest and decreased the eclosion rate of its adults.
