Abstract: The trap lamp with the wavelengths of 300 nm,300 nm,380 nm,380 nm,460 nm,500 nm,540 nm and 580 nm and the power of 8 W was used to snare adults of Parocneria orienta Chao in the field. The trap results showed that the trap lamp with eight kinds of wavelengths exhibited different effects,and the trap lamp with the wavelength of 340 nm and the power of 8 W had the best trapping effect. The trap lamp with the wavelength of 340 nm and the power of 8 W had trapping effect on adults of Parocneria orienta Chao within 60 minutes and 180 metres,and yet the trap rate more than 87.1% was within distance of 120 metres.
