以柑橘木虱信息素复合诱捕器进行橘树树冠挂放不同高度及方位诱集柑橘木虱成虫的试验,结果表明:诱捕器挂放高度以橘树树冠的顶部较好,比挂放在中部和基部的诱集虫量分别增加25.2头/套、42.8头/套,诱虫率分别增加50.2%、85.3%。挂放方位以树冠外延东部、南部的诱虫量偏好,其东部平均每套34.4头、南部33.4头。同时,建立人工目测成虫与诱捕器诱集的成虫之间的线性方程为y=0.727x-12.47;目测若虫和成虫的总虫量和诱捕器的成虫数量之间的线性方程为y=0.711x+9.161。诱捕器可替代目前采用人工田间目测柑橘木虱的监测方法。
The experimental results showed that the height of the trap was better on the top of the canopy of orange trees than on the middle of the canopy And the number of trap insects increased by 25.2 heads / sets and 42.8 heads / sets respectively, and the attractant rates increased by 50.2% and 85.3% respectively. In the eastern part of the canopy, the number of insect-attracting populations in the eastern part of the crown is 34.4 in the eastern part and 33.4 in the southern part. At the same time, the linear equation between the adults and traps was established as y = 0.727x-12.47. The linear equation between the total number of visual nymphs and adults and the number of adults of the trap was y = 0.711x +9.161. Traps can replace the current monitoring methods for visual inspection of citrus psyllid in a field.
