摘　　要：为筛选出效果较佳且适用的性信息素诱芯进行甘薯小象甲的监测与防控,从不同配方信息素诱芯、不同诱芯载体类型、诱捕器不同悬挂高度等几个方面测试比较了引诱剂对甘薯小象甲的诱捕效果。结果表明:诱芯A的总诱虫量、日均诱虫量以及最高单次诱虫量均显著高于其他3种诱芯;橡皮头式载体和毛细管式载体的引诱效果好,与棉芯载体效果差异极显著(P<0.01),2种载体引诱持效期都达到60 d以上;诱捕器5种不同悬挂高度比较,以诱捕器底部与地面齐平或高于地面10 cm的引诱效果最好。建议福建地区用甘薯小象甲性信息素诱芯A搭配黄色桶型诱捕器进行甘薯小象甲的监测与绿色防控。In order to screen out the effective and applicative sex pheromone lure for monitoring and controlling Cylas formicarius,the trapping effects of sex attractants on Cylas formicarius were tested and compared from the aspects of different formulas of lure,different types of lure carrier,and different hanging heights of trap.The results showed that the total trapping amount,daily average trapping amount and single maximum trapping amount of lure A were all more than those of other three lures;the trapping effects of rubber tip carrier and capillary carrier were better,which were significantly different from that of cotton carrier(P<0.01),and the persistence of them were both above 60 d.The comparison of 5 different hanging heights of trap showed that the trapping effects were the best when the trap bottom was at or 10 cm above the ground level.It's suggested that Cylas formicarius sex pheromone lure A with yellow barrel trap could be used for monitoring and green control of Cylas formicarius in Fujian Area.
