Hercon散布器被（Z，E）- 9,11 -十四二烯乙酸酯（1.5 g/ha）吸附，间隔65 m（每0.4 ha一个散布器），有效地破坏了沿海夜蛾的通讯约4周。这可以从诱捕器捕获的数量和在信息素处理的试验区捕获至少一只雄性的雌性诱捕器数量的减少中推断出来。Hercon施药器的信息素释放速率为一级：第一天平均释放1.4 mg/cm2 /天，第9天至第24天平均释放约0.6 mg/cm2 /天。大部分信息素（约87%）在前24天内释放。在不添加任何稳定剂或抗氧化剂的情况下，层压结构有效地保护了信息素，防止了信息素的氧化或异构化。从分布较广的Hercon喷雾器中释放信息素的方法是一种很有应用前景的方法。
Hercon dispensers, adsorbed with ( Z,E )-9, 11-tetradecadienyl acetate (1.5 g/ha) and located 65 m apart (one dispenser per 0.4 ha), effectively disrupted communication in Spodoptera littoralis for about 4 weeks. This was inferred from the reduction in trap captures and in number of virgin female traps that captured at least one male in the pheromone-treated vs. control plots. The release rate of the pheromone from the Hercon dispenser was of the first order: an average of 1.4 mg/cm2 per day was released during the first days, and ca. 0.6 mg/cm2 per day during days 9 to 24. Most of the pheromone (ca. 87%) was emitted within the first 24 days. The laminated structure protected the pheromone effectively, and oxidation or isomerization was prevented without any addition of stabilizer or antioxidant. The method of emitting pheromone from widely separated Hercon dispensers seems promising for applied control of S. littoralis .
