Abstract The brown marmorated stink bug, Halyomorpha halys (Stål) (Hemiptera: Pentatomidae) is attracted to its male-produced aggregation pheromone, a ∼3.5:1 mixture of (3S,6S,7R,10S)- and (3R,6S,7R,10S)-10,11-epoxy-1-bisabolen-3-ol (SSRS and RSRS respectively), and also to the pheromone of its Asian sympatric species Plautia stali Scott (Hemiptera: Pentatomidae), methyl (2E,4E,6Z)-2,4,6-decatrienoate (MDT). A stereoisomeric mixture of (7R) 10,11-epoxy-1-bisabolen-3-ols (= mixed murgantiols) is used together in commercialized products with MDT because the latter is a synergist for H. halys attraction to mixed murgantiols. However, the optimal ratio for MDT combination with mixed murgantiols, and the sensitivity of bug captures to variation in ratio of the two pheromone components, have not been tested to date. Using black pyramid traps at two sites (in Maryland and West Virginia, United States), different ratios of mixed murgantiols to MDT were tested over two entire seasons. Also, captures using various ratios of the two active pheromone stereoisomers were undertaken in month-long trials with and without MDT. Results showed that H. halys adult and nymphal captures were relatively insensitive to the ratio of synthetic pheromone (mixed murgantiols) to MDT, as long as each was present in the trap. Captures of adults and nymphs were responsive to the lure loading of the SSRS isomer, but relatively insensitive to levels of the minor component, RSRS.The relative insensitivity of H. halys to these attractant ratios gives flexibility to development of more cost-efficient synthesis and trapping as well as other semiochemical-based management tactics.

有和没有增效剂的信息素成分的吸引力，甲基 (2E,4E,6Z)-2,4,6-十三烯酸，对棕色 Marmorated 臭虫（半翅目：五足科）

摘要 棕色砗磲臭虫 Halyomorpha halys (Stål) (Hemiptera: Pentatomidae) 被其雄性产生的聚集信息素所吸引，这是一种 (3S,6S,7R,10S)- 和 (3R,6S 7R,10S)-10,11-epoxy-1-bisabolen-3-ol（分别为 SSRS 和 RSRS），以及其亚洲同域物种 Plautia stali Scott（半翅目：五足科）的信息素，甲基（2E，4E， 6Z)-2,4,6-癸三烯酸酯 (MDT)。(7R) 10,11-epoxy-1-bisabolen-3-ols（= 混合 murgantiols）的立体异构混合物与 MDT 一起用于商业化产品，因为后者是 H. halys 对混合 murgantiols 吸引力的增效剂。然而，MDT 与混合 murgantiols 组合的最佳比例，以及 bug 捕获对两种信息素成分比例变化的敏感性，迄今尚未经过测试。在两个地点（美国马里兰州和西弗吉尼亚州）使用黑色金字塔陷阱，在整个两个季节测试了混合摩尔根醇与 MDT 的不同比例。此外，在使用和不使用 MDT 的为期一个月的试验中，使用两种活性信息素立体异构体的不同比例进行捕获。结果表明，H. halys 成虫和若虫捕获对合成信息素（混合摩尔根醇）与 MDT 的比率相对不敏感，只要它们都存在于陷阱中。成虫和若虫的捕获对 SSRS 异构体的诱饵负载有反应，但对次要成分 RSRS 的水平相对不敏感。 H. halys 对这些引诱剂比例的相对不敏感为开发更具成本效益的合成和诱捕以及其他基于化学信息素的管理策略。
