| 摘 要： | 为探索青杨脊虎天牛的无公害控制技术,采用不同波长(320~560 nm)黑光灯对其成虫进行诱捕。结果,青杨脊虎天牛成虫对低波长区间(320~368 nm)具有趋光性,对368 nm(黄)较360 nm(绿)更为敏感,处理时间18:00—24:00中,最佳诱捕时间为20:00—22:00,晴天的诱捕效果要比晴转阴和阴天要好,黑光灯可作为监测和控制青杨脊虎天牛的监测辅助工具。测定7种白僵菌菌株制作的无纺布菌条对青杨脊虎天牛的毒力,各菌株在处理后30 d内孢子含量逐渐下降,对青杨脊虎天牛防治效果最佳的菌株为球孢白僵菌Bb01和布氏白僵菌Bb CF327。

| Abstract: | To explore efficient and environmental safely controlling techniques toXylotrechus rusticus L., black light lamp in different wavelengths(320-560 nm) was employed to trap adults ofX. rusticus L. outdoors. The results showed thatX. 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 monitoringor control ofX. rusticus L. population. The pathogenicity of non-woven fabric fungal bands with 7 different strains of Beauveriasp. toX. 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 andBeauveria brongniartii BbCF327 showed the best effect for control ofX.rusticus L. larvae. |
