The brown marmorated stink bug (BMSB), (Stål) (Hemiptera: Pentatomidae), is a polyphagous pest native to East Asia and invasive in many countries. Various approaches have been used to control its spread, including IPM strategies. Monitoring pest populations is the starting point for developing an appropriate control strategy. The most common attractant for is based on its two-component aggregation pheromone ((3S,6S,7R,10S)-10,11-epoxy-1-bisabolen-3-ol and (3R,6S,7R,10S)-10,11-epoxy-1-bisabolen-3-ol), in combination with the synergist methyl (2E,4E,6Z)-2,4,6-decatrienoate. The aim of this research was to evaluate the most effective combination of the pheromone and the synergist for different types of adjuvants and dispensers, i.e., Blister Pack, Wax Tablet, and Polymers (Non-Biodegradable and Biodegradable Polymers). Field trials were carried out in Northern Italy, during summer and autumn 2023 and 2024. The effectiveness of the different combinations was evaluated on the basis of the number of individuals caught in sticky traps baited with the different treatments, separated by 50 m each. Individuals actively collected in the surrounding vegetation were also monitored. During the first year, the Non-Biodegradable Polymer performed better than the others. In the second year, captures were quite similar among the tested dispensers, and all were higher than the control. Captures of non-target stink bugs and other bugs of the Coreidae family were evaluated but, in most cases, were negligible. Under laboratory conditions, the release rate of the chemical compounds differed depending on the type of dispenser. Our results confirm the specificity of the semiochemical lure combination tested towards and its persistence in the field for at least 12 weeks. The results could be useful for improving the effectiveness of trapping, as well as for attract-and-kill or push-pull strategies of the pest.
棕色球形异蝽（BMSB），（斯塔尔）（半翅目：蝽科），是一种原产于东亚的多食性害虫，现已入侵许多国家。人们采用了各种方法来控制其传播，包括综合虫害管理策略。监测害虫种群是制定适当控制策略的起点。对棕色球形异蝽最常用的引诱剂是基于其双组分聚集信息素（（3S,6S,7R,10S）-10,11-环氧-1-荜澄茄烯-3-醇和（3R,6S,7R,10S）-10,11-环氧-1-荜澄茄烯-3-醇），并与增效剂甲基（2E,4E,6Z）-2,4,6-癸三烯酸酯结合使用。本研究的目的是评估信息素与增效剂针对不同类型助剂和诱捕器（即泡罩包装、蜡片和聚合物（不可生物降解和可生物降解聚合物））的最有效组合。2023年和2024年夏秋两季在意大利北部进行了田间试验。根据用不同处理诱饵的粘性诱捕器捕获的棕色球形异蝽个体数量来评估不同组合的有效性，每个诱捕器相隔50米。还监测了在周围植被中主动收集的个体。在第一年，不可生物降解聚合物表现优于其他材料。在第二年，测试的诱捕器捕获量相当相似，且均高于对照。对非目标臭虫和缘蝽科其他虫子的捕获情况进行了评估，但在大多数情况下可以忽略不计。在实验室条件下，化合物的释放速率因诱捕器类型而异。我们的结果证实了所测试的化学引诱剂组合对棕色球形异蝽的特异性及其在田间至少12周的持久性。这些结果对于提高棕色球形异蝽诱捕的有效性以及害虫的诱捕杀灭或推拉策略可能是有用的。
