Abstract

Aggregation-sex pheromones, that attract both sexes, are produced by male cerambycid beetles (Coleoptera: Cerambycidae) of the subfamilies Cerambycinae, Lamiinae, and Spondylidinae. Here, we present the results of a field experiment conducted at multiple sites in southern Texas, primarily near the border with the state of Tamaulipas, Mexico. At each site, we deployed traps baited with a 6-component blend of known pheromones of cerambycine and lamiine species + an ethanol lure, a 5-component blend of lamiine pheromones + an ethanol lure, an ethanol lure alone, and a solvent control. Over a ~3-wk period, 846 beetles of 51 species were trapped, representing 36 cerambycine, 14 lamiine, and one prionine species, and one species in the closely related family Disteniidae. For species collected from at least 5 study sites, nonparametric tests of treatment effects revealed that the generic 6-component blend + ethanol attracted significant numbers of one cerambycine species, while the lamiine blend + ethanol attracted one cerambycine species and 2 lamiine species. The ethanol lure attracted 2 additional cerambycine species in significant numbers. For species that were captured at fewer sites, chi-square goodness-of-fit tests showed that the 2 pheromone blends + ethanol attracted significant numbers of another 6 species of cerambycines and 4 species of lamiines. Captures noteworthy from the standpoint of collection records include the rare species Leptostylopsis lutea Dillon, and Lochmaeocles cornuticeps cornuticeps (Schaeffer) and Thryallis undatus (Chevrolet), 2 species which have rarely been reported outside Sabal Palm Sanctuary in Cameron County, Texas.

在德克萨斯州南部测试长角甲虫(鞘翅目:天牛科)的多物种信息素混合物。
聚集性信息素是由天牛亚科、天牛亚科和天牛亚科的雄性天牛甲虫(鞘翅目:天牛科)产生的,可以吸引两性。在这里,我们展示了在德克萨斯州南部多个地点进行的实地实验的结果,主要是在墨西哥塔毛利帕斯州边境附近。在每个地点,我们部署了诱捕器,诱捕器由已知的神经素和胺类信息素的6组分混合物+乙醇诱捕器,胺类信息素的5组分混合物+乙醇诱捕器,乙醇诱捕器单独诱捕器和溶剂对照。在约3周的时间内,共捕获51种846只甲虫,其中天牛素36种,胺类14种,脯氨酸类1种,近缘虫科1种。对从至少5个研究点收集的物种进行处理效果的非参数测试表明,通用的6组分混合物+乙醇吸引了大量的一种神经酰胺,而胺混合物+乙醇吸引了一种神经酰胺和两种神经酰胺。乙醇诱捕剂额外吸引了2种数量可观的天牛碱。对于在较少地点捕获的物种,卡方拟合优度检验表明,2种信息素混合物+乙醇吸引了另外6种神经酰胺和4种胺。从收集记录的角度来看,值得注意的是稀有物种Leptostylopsis lutea Dillon, Lochmaeocles cornuticeps cornuticeps (Schaeffer)和Thryallis undatus (Chevrolet),这两个物种在德克萨斯州Cameron县Sabal棕榈保护区之外很少报道。
