[Objective]The aim was to compare control effects of trapping lamps with different wavelengths on soybean pests.[Method] Three kinds of lamps with different wavelengths were used to conduct pest control test in soybean fields.[Result]The trapping effects of three kinds of lamps with different wavelengths on soybean pests were significantly different.Among them,the trapping effect of No.2 light with wavelength of 400-460 nm was significantly better than the other two lamps;No.1 light with wavelength of 330-400 nm had no obvious difference in trapping effect with No.3 light with wavelength of 450-510 nm.[Conclusion]The research result provided theoretical basis for popularized application of trapping lamp in production.
