Field-trapping experiments with synthetic 2,7-nonadiyl dibutyrate, the female-produced sex pheromone of the orange wheat blossom midge, Sitodiplosis mosellana (Géhin), demonstrated that pheromone traps were highly attractive to males and caught very few non-target organisms. Different formulations of pheromone were tested to identify the optimum release rate and dispenser type for use in pheromone traps in the UK. Key findings were that racemic pheromone was as effective as enantiomerically pure (2S,7R)-2,7-nonadiyl dibutyrate, that release rates higher than 0.5 microg day(-1) were not necessary and that the optimal formulation was a 1 mg pheromone loading in a rubber septum. Pheromone traps gave a reliable indication of peak midge emergence, onset of flight and abundance of midges throughout the season. A strong correlation between maximum trap catch and crop infestation levels was obtained.
用合成的2,7 - 壬二烯二丁酸酯（橙色麦瘿蚊雌性产生的性信息素，橙色麦瘿蚊学名：Sitodiplosis mosellana (Géhin)）进行的田间诱捕实验表明，信息素诱捕器对雄性具有高度吸引力，并且捕获的非目标生物极少。测试了不同的信息素配方，以确定在英国用于信息素诱捕器的最佳释放速率和 dispenser 类型。主要发现是外消旋信息素与对映体纯的(2S,7R)-2,7 - 壬二烯二丁酸酯效果相同，高于0.5微克/天(-1)的释放速率并非必要，最佳配方是在橡胶隔膜中装入1毫克信息素。信息素诱捕器能可靠地指示瘿蚊羽化高峰期、飞行开始时间以及整个季节瘿蚊的数量。诱捕器捕获量最大值与作物受侵染水平之间存在很强的相关性。 （注：原文中dispenser未找到合适的中文释义，保留英文）
