A number of recent studies have demonstrated the potential for using blends of pheromones of cerambycid beetles to attract several species simultaneously. Here, we tested the effects of adding the pheromones of two invasive species, Trichoferus campestris (Faldermann) and Aromia bungii (Faldermann), on the attraction of native species to a generic blend of synthesized pheromones, in season-long field trials at 12 sites in Pennsylvania. Of the four species attracted in significant numbers, Megacyllene caryae (Gahan), Phymatodes amoenus (Say), and P. testaceus (L.) (all subfamily Cerambycinae) were not significantly affected by the addition of the T. campestris pheromone trichoferone and the A. bungii pheromone (E)-2-cis-6,7-epoxynonenal to the generic blend. In contrast, trap catches of Sternidius alpha (Say) (subfamily Lamiinae) were completely shut down by addition of the pheromones of the two exotic species. In addition, there was no indication that any native species were attracted to trichoferone or (E)-2-cis-6,7-epoxynonenal, suggesting that these pheromones are probably not used by species native to eastern North America.

混合本地和外来天牛甲虫信息素的田间试验

最近的一些研究已经证明了使用天牛甲虫的信息素混合物同时吸引几个物种的潜力。在这里，我们在 12 个地点进行了为期一季的田间试验，测试了添加两种入侵物种 Trichoferus campestris (Faldermann) 和 Aromia bungii (Faldermann) 的信息素对本地物种对合成信息素的通用混合物的吸引力的影响在宾夕法尼亚州。在大量吸引的四个物种中，Megacyllene caryae (Gahan)、Phymatodes amoenus (Say) 和 P. testaceus (L.)（均为 Cerambycinae 亚科）未受到添加 T. campestris 信息素 trichoferone 和A. bungii 信息素 (E)-2-cis-6,7-epoxynonenal 用于通用混合物。相比之下，Sternidius alpha (Say) (Lamiinae 亚科) 的诱捕器通过添加两种外来物种的信息素完全关闭。此外，没有迹象表明任何本地物种被毛滴虫酮或 (E)-2-cis-6,7-epoxynonenal 吸引，这表明北美东部的本地物种可能不使用这些信息素。
