Synthetic sex pheromone of the pea mothCydia nigricana, (E,E)-8,10-dodecadien-1-yl acetate (E8,E10-12: Ac), was applied in polyethylene dispensers at a rate of 30 g/ha and 600 dispensers/ha in a 0.6-ha pea field. The release rate ofE8,E10-12: Ac was 140 mg/ha/day after six days, and 82 mg/ha/day after 20 days. Aerial concentrations ofE8,E10-12: Ac, as measured by a portable EAG apparatus, ranged from 2 ± 2 to 7 ± 3 ng/m(3). The antennal signal was high and rather constant within pea canopy, but was lower and fluctuated strongly above canopy. Initially, >99% isomerically pureE8,E10-12: Ac was released, and male moths were attracted to dispensers. After nine days, isomeric blend composition had equilibrated to approx. 92%E8,E10-12: Ac and 8% of the inhibitory isomersE,Z-,Z,E-, andZ8,Z10-12: Ac. Males were then repelled from the pheromone-permeated field. Traps baited with 100 µgE8,E10-12: Ac caught 258 ± 133C. nigricana males/trap in the control, but no males at all in the disruption field.
人工合成的豌豆银纹夜蛾性信息素，（E，E）-8，10-十二碳二烯-1-基乙酸酯（E8，E10-12：Ac），以 30 克/公顷和 600 个/公顷的剂量施用于聚乙烯分配器中，在 0.6 公顷的豌豆田中。六天后，E8，E10-12：Ac 的释放率为 140 mg/ha/天，20 天后为 82 mg/ha/天。通过便携式 EAG 仪器测量，空气中的 E8，E10-12：Ac 浓度范围为 2 ± 2 至 7 ± 3 ng/m(3)。在豌豆冠层内，触角信号高且相当稳定，但在冠层上方，信号较低且波动较大。最初，释放出>99%的同系物纯 E8，E10-12：Ac，雄性飞蛾被吸引到分配器上。九天后，同系物混合组成达到约 92%的 E8，E10-12：Ac 和 8%的抑制同系物 E，Z-，Z，E-和 Z8，Z10-12：Ac。然后，雄性对渗入信息素的田地产生排斥。用 100 µg E8，E10-12：Ac 诱捕的诱捕器捕获了 258 ± 133 个 C.nigricana 雄性/诱捕器在对照中，但在干扰场中根本没有雄性。
