摘要： 对不同剂量、不同保存期的性诱剂和几种常见诱捕器进行了田间诱蛾效果比较研究。结果表明，诱芯所含的性诱剂的剂量以300 μg为宜；在低温条件下保存1年对其诱蛾效果影响不大；泥盆诱捕器的诱蛾效果不理想，粘胶诱捕器的诱蛾效果也不及水盆诱捕器，但操作较为方便；在田间设置时，其适宜高度需随水稻高度而变化。

Abstract: Certain factors which could affect pheromone trap performance were studied under field conditions, in order to develop methods for population controlling of Chilo suppressalis (Walker), using female sex attractants. Field results showed that the dose of 300 μg sex pheromones per lure was a preferably applied type among the serial of lure doses tested. The longer the lure storage time kept in cool condition, the less the catch of lure was. The efficiency of lures with the storage time over one year was significantly declined. Catches of male stem borer moths in four types of trap ( one lure per trap ) were compared. Water trap caught the highest number of males and was more efficient among them. Soil-trap and Sticky-trap were slightly efficient types in catching males though in lesser numbers and would be applied because of their cheapness and ease operation. The size of catches at different levels varied in the fields. The plant height is the optimum height for trapping.
