在甘肃省高台县通过对三角胶粘式和水盆式这2种类型苹果蠹蛾Cydia pomonella（L.）诱捕器的田间比较研究。结果显示,二者在诱捕效率上存在的明显差异。在苹果蠹蛾密度较低的条件下,三角胶粘式诱捕器平均日诱捕量为2.50只,比水盆式诱捕器高出近2.84倍,最早监测到成虫的时间也比水盆式诱捕器提前3-4d,因此,三角胶粘式诱捕器具有更高的监测效率。结果还显示地面植被的遮盖极大地降低诱捕器的诱捕效果,严重时会使诱捕器对密度较低的苹果蠹蛾种群的监测功能丧失。

英文摘要：

An obvious efficiency difference between two pheromone trap types was found by field experiments on capturing adult codling moth, Cydia pomonella （ L. ）, by Delta sticky trap （ DS trap） and water basin trap （WB trap） in Gaotai county, Gansu Province（N 39°20′839, E 099°37′507）. In low population density, DS trap could catch 2.5 adults per day which was 2.84 times more than WB trap. Moreover, DS traps could capture adult moth in 3 - 4 days earlier than the WB traps while they used to monitor codling moth for the earliest capturing time. DS trap was more efficient to be used in monitoring the emergence and population of codling moth. On the other hand, it was found that the ground vegetation cover plants greatly reduced trap efficiency and their monitoring function could be lost for serious lower codling moth density.
