摘要
为了明确甘薯蚁象的发生情况,2009、2010年采用性诱剂诱集的方法对福建福州和莆田甘薯蚁象的发生情况进行了监测,2011年对性诱剂的诱捕器和放置密度进行了比较研究。结果表明,不同年份甘薯蚁象的发生高峰期不尽相同,总体上以7-10月为发生最严重的时期;在连年种植、管理粗放的甘薯田块蚁象发生严重。商品黄色塑料筒诱捕器的诱集效果优于自制漏斗型瓶装诱捕器;但是自制漏斗型瓶装诱捕器较为实用;不同厂家的诱芯田间诱虫效果差异不明显;每667m2放置3个诱芯可以有效地诱集蚁象。性诱剂诱捕区与非诱捕区相比,危害明显减轻,甘薯产量明显增加,因此,采用性诱剂诱捕的措施可以减轻甘薯蚁象的危害。
During 2009-2010,occurrence of the sweetpotato weevil,Cylasformicarius,were monitored by pheromone traps in the sweetpotato field in Fuzhou and Putian,Fujian,China.In 2011,pheromone trap types and lure densities were optimized.The results showed that the occurrence of peak period was not the same in different years.But the trend was similar to each other.The most serious period was from July to October.In continuous planting and management rough fields,sweetpotato weevils were more serious.The commercial yellow plastic traps captured significant number of weevils,but the handmade plastic funnel traps were the most practical for capturing males.The difference of lures produced by two companies was not significant in trapping efficacy.The setting of three lures per 667 m2captured weevils effectively.Compared with the areas without traps,the damage in trapped areas reduced significantly and the yield increased.
