摘　　要：在杭州、桐庐和嘉兴三地田间,对不同剂型性信息素诱芯对二化螟雄蛾的诱捕效果进行比较,筛选出对二化螟雄虫诱捕效果最佳的剂型。诱捕试验采用水盆和筒形两种诱捕法,采用随机区组设计,通过对每天诱集到的雄蛾进行计数,比较不同性信息素配比和不同剂量信息素使用对诱蛾效果的影响。结果表明,三地点的试验结果均以编号为CS2007247A和CS2007247B的效果最佳;诱集效果随着在田间的暴露期延长而成幂函数下降。A series of field screening experiments were carried out to compare the effiency of different compositions of pheromone in capillary during the second generation of adults of Chilo suppressalis in 2007 in three sites, i.e. Hang- zhou, Tonglu and Jiaxing, in Zhejiang province, China. The experiment used the water-pan trap and cylindric trap, and was in a complete randomized block design. The number of male moths trapped was counted daily to compare the trapping effect of different composition and dosage of pheromone constituents. The results showed that the blends co- ded as CS2007247A and CS2007247B were the most attractive to male moths of Chilo suppressalis. The trapping ca- pability of the lure degraded as a negative power function with the increase of exposure date.
