粘虫板监测诱杀云杉腮扁叶蜂研究

Study on trapping of Cephalcia abietis by sticky board

为明确黄色和绿色粘虫板对云杉腮扁叶蜂的诱捕效果,利用黄色和绿色交叉式粘虫板诱捕器开展了诱捕云杉腮扁叶蜂效果的比较试验,并进行了设置技术研究和种群发生期监测与诱杀防治试验。结果表明,黄色交叉式粘虫板诱捕器的诱捕效果比绿色的好。黄色粘虫板设置技术研究显示,虽然粘虫板设置于不同方位、坡向和高度对诱捕效果的影响不显著,但是建议在生产防治中粘虫板应设置于东或南方位、山脊或阳坡和树冠上层。成虫发生期监测表明,成虫的始见期为6月10日左右,高峰期为7月1日,末期为7月19日,成虫持续期为40 d。应用黄色粘虫板诱杀防治云杉腮扁叶蜂,防治效果显著。利用黄色粘虫板监测和诱杀云杉腮扁叶蜂的技术应进行大规模推广应用。

In order to determine the trapping effects of yellow and green sticky board on Cephalcia abietis,a comparative experiment was carried out by using yellow and green cross-type sticky board,and the settings of technique,monitoring of population occurrence period and trapping and controlling experiments were carried out as well.The results showed that the yellow crossed-type sticky board had better trapping effects than the green one.The study of settings of yellow sticky board indicated that it had no significant effect on the trappings which were set in different directions,slope and height,and it was suggested that the sticky board should be set in the east or south directions,in ridge or sunny slope and upper canopy in production control.The adult insects monitoring showed that the first appearance date of adult insects was around June 10th,the peak date appeared on July 1st,the end date took place on July 19th,and the duration of adult insects was 40 days.The effects of the yellow sticky board for trapping the C.abietis were remarkable.The technique of using yellow sticky board to monitor and trap the C.abietis should be popularized and applied on a large scale.
