Abstract In 2014–2019, we conducted six experiments in north-central Georgia in an attempt to verify the aggregation pheromone response of the ambrosia beetle Gnathotrichus materiarius (Fitch) (Coleoptera: Curculionidae: Scolytinae: Scolytini: Corthylina) to sulcatol known to be produced by male G. materiarius; we failed to catch any G. materiarius. However, we did find that another corthyline ambrosia beetle species Monarthrum mali (Fitch) was attracted to (R)-(–)-sulcatol, whereas the longhorn beetle Leptostylus asperatus (Haldeman) (Coleoptera: Cerambycidae: Lamiinae) was attracted to (S)-(+)-sulcatol. Attraction of both species was unaffected by the respective antipodes. Ethanol enhanced attraction of both species to traps baited with sulcatol. In at least one experiment, attraction to ethanol-baited traps was enhanced by sulcatol for Xylosandrus crassiusculus (Motschulsky), Xyleborus spp., and Hypothenemus spp. but reduced for Cnestus mutilatus (Blandford) (Coleoptera: Curculionidae: Scolytinae). Additionally, traps baited with ethanol and racemic sulcatol [50% (S)-(+): 50% (R)-(-)] caught the greatest numbers of four species of beetle predators: Coptodera aerata Dejean (Coleoptera: Carabidae), Colydium lineola Say (Coleoptera: Zopheridae), Madoniella dislocata (Say), and Pyticeroides laticornis (Say) (Coleoptera: Cleridae). Ethanol but not sulcatol attracted Temnoscheila virescens (F.) (Coleoptera: Trogossitidae). Information on interspecific relationships within forested communities may help us to better determine the roles of these species in maintaining stable and resilient forested ecosystems.

Sulcatol：对马利单叶螟（鞘翅目：仙茅科：Scolytinae）、细角螟（鞘翅目：天牛科）和相关捕食者的对映体特异性引诱剂

摘要 2014-2019 年，我们在乔治亚州中北部进行了 6 次实验，试图验证甘草甲虫 Gnathotrichus materiarius (Fitch)（鞘翅目：仙茅科：Scolytinae：Scolytini：Corthylina）对已知产生的 sulcatol由雄性 G. materiarius 提供；我们没有发现任何 G. materiarius。然而，我们确实发现另一种 Corthyline ambrosia 甲虫物种 Monarthrum mali (Fitch) 被 (R)-(-)-sulcatol 所吸引，而长角甲虫 Leptostylus asperatus (Haldeman)（鞘翅目：天牛科：Lamiinae）被（S )-(+)-硫醇。两个物种的吸引力都不受各自对映体的影响。乙醇增强了两种物种对硫卡醇诱饵的吸引力。在至少一项实验中，Sulcatol 增强了对乙醇诱饵诱捕器的吸引力，对 Xylosandrus crassiusculus (Motschulsky)、Xyleborus spp. 和 Hypothenemus spp。但减少了 Cnestus mutilatus (Blandford) (鞘翅目: Curculionidae: Scolytinae)。此外，用乙醇和外消旋硫卡酚 [50% (S)-(+): 50% (R)-(-)] 诱饵诱捕的四种甲虫捕食者数量最多：Coptodera aerata Dejean（鞘翅目：Carabidae）， Colydium lineola Say (Coleoptera: Zopheridae), Madoniella dislocata (Say), 和 Pyticeroides laticornis (Say) (Coleoptera: Cleridae)。乙醇而不是硫卡酚吸引了 Temnoscheila virescens (F.)（鞘翅目：Trogossitidae）。关于森林群落内种间关系的信息可能有助于我们更好地确定这些物种在维持稳定和有弹性的森林生态系统方面的作用。
