在英国，橙子小麦开花吸浆虫（Sitodiplosis mosellana）监测诱捕系统的开发已经取得了相当大的进展。信息素2，7-壬二基二丁酸酯引诱雄性昆虫进入陷阱。在信息素陷阱中捕获的OWBM的数量给出了一个可靠的指示，在麦田附近的飞行活动的开始，并与随后的作物侵染水平的严重程度有很强的相关性。诱捕器的高灵敏度超过了信息素诱捕器捕捉雄性而不是雌性昆虫的事实。信息素诱捕器可以用来警告农民，当蠓的水平预计将是破坏性的高。杀虫剂需要在检测到高水平的吸浆虫后立即使用，因为杀虫剂只针对成虫和幼虫，然后才能到达谷物。设计了一个决策支持模型，以开发信息素陷阱进行风险评估，并帮助农民决策。它考虑到，可以有很大的变化，从现场到现场的陷阱捕获和一个领域内的侵扰是最好的解释信息素陷阱捕获在邻近领域。在一个典型的一年，有一个良好的相关性陷阱捕获和作物损害程度，但在一个非典型的一年女性运动之间的领域可能会复杂化。
Considerable progress has been made towards the development of a monitoring trap system for orange wheat blossom midge (OWBM), Sitodiplosis mosellana, in the UK. The pheromone 2,7-nonadiyl dibutyrate lured male insects into traps. The number of OWBM caught in the pheromone traps gave a reliable indication of the onset of flight activity in the vicinity of wheat fields and had a strong correlation with the severity of subsequent crop infestation levels. The high sensitivity of the traps outweighed the fact that pheromone traps catch male rather than female insects. Pheromone traps can be used to give a warning to farmers of when midge levels are expected to be damagingly high. The insecticide needs to be applied soon after detection of high levels of midge because insecticide only targets adults and larvae before they reach the grain. A decision support model was devised to develop pheromone traps for risk assessment and aid farmer decision making. It takes into account that there can be large variations in trap catch from field to field and that infestation within a field was best explained by pheromone trap catches in neighbouring fields. In a typical year, there is a good correlation between trap catch and crop damage level but in an atypical year movement of females between fields could complicate this.
