通过田间系统调查,明确了非结球芽甘蓝上B型烟粉虱的发生规律。研究了田间不同高度黄板对非结球芽甘蓝B型烟粉虱成虫诱杀数量的影响以及不同密度对田间种群的控制效果。试验结果表明,黄板底部离地面5cm处理的诱杀量显著高于其他处理,田间每667m2使用黄板60块,7d后田间B型烟粉虱种群的控制效果达65.3%。应用黄板诱杀B型烟粉虱成虫是非结球芽甘蓝B型烟粉虱综合治理中经济有效的防控技术之一。
Through field investigation, the occurrence of B. tabaci on non-bulbous brussels was clarified. The effects of different altitudes of the yellow board on trapping and killing of B. tabaci B-biotype adults and the control effects of different densities on field populations were studied. The results showed that the amount of trapping and killing of 5 cm from the ground at the bottom of yellow board was significantly higher than that of other treatments. 60 blocks of yellow board per 667 m2 were used in the field. After 7 days, the control efficacy of B. tabaci B + population was 65.3%. It is one of the economical and effective prevention and control technologies in the comprehensive management of B. tabaci B-type B. tabaci.
