Tree volatiles and pheromones produced by southern bark beetles were bioassayed for response by the clerid predatorThanasimus dubius (F.). Upwind flights in a laboratory olfactometer, modified from Visser (1976), were used to determine the attractiveness of compounds. Differences in response to a solvent control and pheromone treatment were tested for statistical significance using the Wilcoxon signed ranks test. Both sexes ofT. dubius responded to frontalin, ipsdienol, and α-pinene in a dose-dependent manner with different but overlapping concentration ranges. Strong differences between the sexes were observed in response totrans-verbenol, verbenone, andl-β-pinene. Neither sex responded to ipsenol orendo-brevicomin.
南方树皮甲虫产生的树木挥发物和信息素被生物测定为 clerid 捕食者 Thanasimus dubius (F.) 的反应。使用改良自 Visser (1976) 的实验室嗅觉计进行顺风飞行，以确定化合物的吸引力。使用 Wilcoxon 符号秩检验测试对溶剂对照和信息素处理的反应差异进行统计显着性检验。雌雄两性的 T. dubius 以剂量依赖性方式对法尼醇、异丁香烯醇和α-蒎烯作出反应，其浓度范围不同但重叠。在 trans-verbenol、马鞭草酮和 l-β-蒎烯方面，两性之间存在明显差异。两性均对异丁香烯醇或endo-brevicomin 没有反应。
