To explore efficient and environmental safely controlling techniques to Xylotrechus rusticus L., black light lamp in different wavelengths(320–560 nm) was employed to trap adults of X. rusticus L. outdoors. The results showed that X. rusticus L. adults exerted phototaxis in low wavelengths range (from 320 nm to 368 nm), and showed the highersensitivity at 368 nm yellow than that at 360 nm green. We found that 20:00 pm to 22:00 pm is the best trapping time from 18:00 pm to 24:00. The trapping efficiencies in a sunny day are better than those in a sunny then cloudy day and in a cloudy day. This suggested that black light trapping could be used as an assist technology for monitoring or control of X. rusticus L. population. The pathogenicity of non–woven fabric fungal bands with 7 different strains of Beauveria sp. to X. rusticus L. was tested. Spores contents of the 7 different strains on the non–woven fabric band were declined continuously in 30 days. Beauveria bassiana Bb01 and Beauveria brongniartii BbCF327 showed the best effect for control of X. rusticus L. larvae.
