Mating disruption is a highly effective pest control technique without the negative impacts of most chemical plant protection products. Traditionally, this control method has been implemented using passive dispensers that release the synthetic sex pheromone of the target pest. However, new sprayable formulations are now available. Due to the recent introduction of these formulations, their application for mating disruption has yet to be fully optimized. This study evaluated the field performance of two spray technologies-unmanned aerial vehicle (UAV) and conventional terrestrial sprayer (TS)-for applying a microencapsulated formulation against the European grapevine moth, Lobesia botrana.
Spray distribution in the orchards revealed that UAV application resulted in higher deposition at the top of the vines, whereas TS achieved greater deposition on the lateral canopy surfaces. Additionally, the UAV setup produced larger droplets, while the TS setup generated a higher number of smaller, more clustered droplets. When measuring airborne pheromone concentration on the treatment day and at 7, 14 and 21 days post-treatment, initial levels were higher with UAV application but declined more rapidly compared to TS.
Both spray technologies delivered sufficient pheromone levels for effective mating disruption. Compared to dispensers, pheromone spraying achieved similar airborne concentrations while using 50% less pheromone. Although this approach shows great potential, further optimization of spray technology is needed to maximize its effectiveness. © 2025 Society of Chemical Industry.
交配干扰是一种高效的害虫防治技术，不会产生大多数化学植物保护产品带来的负面影响。传统上，这种防治方法是使用被动式分配器来释放目标害虫的合成性信息素。然而，现在有了新的可喷雾制剂。由于这些制剂是最近才推出的，它们在交配干扰方面的应用尚未得到充分优化。本研究评估了两种喷雾技术——无人机（UAV）和传统地面喷雾器（TS）——在应用微胶囊制剂防治欧洲葡萄蛾（Lobesia botrana）方面的田间性能。
果园中的喷雾分布显示，无人机喷雾在葡萄藤顶部的沉积量更高，而地面喷雾器在树冠侧面的沉积量更大。此外，无人机装置产生的液滴更大，而地面喷雾器装置产生的小液滴数量更多且更密集。在处理当天以及处理后7天、14天和21天测量空气中的信息素浓度时，无人机喷雾的初始浓度较高，但与地面喷雾器相比下降得更快。
两种喷雾技术都能提供足够的信息素水平以实现有效的交配干扰。与分配器相比，信息素喷雾在使用的信息素减少50%的情况下达到了相似的空气中浓度。尽管这种方法显示出巨大潜力，但仍需要进一步优化喷雾技术以使其效果最大化。© 2025化学工业协会。
