利用粘虫板诱捕落叶松红腹叶蜂成虫效果初探

The Technique of Using Sticky Colored Card to Trap the Adult of Pristiphora erichsonii

在宁夏六盘山国家级自然保护区利用绿色、黄绿色、土黄色、红色等不同颜色粘虫板,研究了羽化期内不同颜色粘虫板诱捕落叶松红腹叶峰成虫效果,结果为,4种颜色粘虫板中绿色效果最好,黄绿色、土黄色次之,红色最差;8个坡向南坡效果最好,西南坡、东南坡次之,东坡、西坡再次之,西北坡、东北坡、北坡较差;5月8-21日为诱捕最佳时段。利用粘虫板防治落叶松红腹叶蜂成虫应以5月8-21日将绿色粘虫板布置于南坡为佳。

Sticking cards of different colors were used in Ningxia Liupanshan National Nature Reserve to study the effects of different colors to trap the adult of Pristiphora erichsonii during its feathering period.The result showed that green was the best one among the four colors,followed by green yellow and earthy yellow.Red has the least effect.Among the eight slope directions,the south slope had the best effect,followed by the southwest,the southeast slope,the east slope,the west,the northwest and the northeast slopes.The north slope had the least effect.May 8 to 21 was the best time to trap the adult of Pristiphora erichsonii.So it is concluded that the best solution is green sticky colored card on the direction of south slope from May 8 to 21 to trap the adult of Pristiphora erichsonii.
