Cosmopolites sordidus is an important pest on banana plantations worldwide. The chemistry of the aggregation pheromone of this insect has been recently resolved and here we present the first evidence from field trails that sordidin, a compound from the male released aggregation pheromone, attracts significant number of weevils only if host plant odors are also present. Sordidin attracts few insects when it is presented without the host plant tissue. However, the attractiveness of host plant tissue increases more than tenfold when it is presented simultaneously with sordidin in field traps. We confirm experimentally that sordidin may be used as part of a system for mass trapping and monitoring this insect.
香蕉球象甲是全球香蕉种植园中的一种重要害虫。该昆虫聚集信息素的化学组成最近已被解析，在此我们展示了田间试验的首个证据：雄虫释放的聚集信息素中的一种化合物——香蕉球象甲素，只有在寄主植物气味也存在时，才会吸引大量象甲。当单独呈现香蕉球象甲素时，吸引的昆虫很少。然而，在田间诱捕器中，当寄主植物组织与香蕉球象甲素同时呈现时，其吸引力会增加十倍以上。我们通过实验证实，香蕉球象甲素可作为该昆虫大规模诱捕和监测系统的一部分。
