[ 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.展开更多
