ABSTRACT We summarize field data on the species composition and seasonal phenology of the community of cerambycid beetles of east central Illinois. Data were drawn from field bioassays conducted during 2009–2012 that tested attraction of adult beetles of diverse species to a variety of synthetic pheromones and host plant volatiles. In total, 34,086 beetles of 114 species were captured, including 48 species from the subfamily Cerambycinae, 41 species from Lamiinae, 19 species from Lepturinae, 2 species from Spondylidinae, and 1 species each from Necydalinae, Parandrinae, Prioninae, and Disteniidae. Most of the best-represented species were attracted to pheromones that were included in field experiments, particularly species that use (R)-3-hydroxyhexan-2-one as a pheromone component. The species captured and their patterns of abundance and seasonal phenology were similar to those in an earlier study conducted in Pennsylvania. The most abundant species identified in both studies included the cerambycines Elaphidion mucronatum (Say), Neoclytus acuminatus acuminatus (F.), Neoclytus mucronatus mucronatus (F.), and Xylotrechus colonus (F.). Cerambycine species became active in an orderly progression from early spring to late fall, whereas most lamiine species were active in the summer and fall, and lepturine species were limited to the summer. Potential cross attraction between some cerambycine species that shared pheromone components may have been averted by differences in seasonal activity period and by minor pheromone components that acted as synergists for conspecifics, antagonists for heterospecifics, or both. These results provide quantitative data on the abundance and seasonal phenology of a large number of species.

伊利诺伊州中东部天牛甲虫的季节性物候学

摘要 我们总结了伊利诺伊州中东部天牛甲虫群落的物种组成和季节性物候的实地数据。数据来自 2009-2012 年期间进行的田间生物测定，该测定测试了不同物种的成年甲虫对各种合成信息素和寄主植物挥发物的吸引力。共捕获甲虫114种34,086只，其中天牛亚科48种，海蛉亚科41种，兔甲亚科19种，甲虫亚科2种，甲虫亚科、虎甲亚科、蜈蚣亚科、蜉蝣科各1种。大多数最具代表性的物种都被包括在现场实验中的信息素所吸引，特别是使用 (R)-3-hydroxyhexan-2-one 作为信息素成分的物种。捕获的物种及其丰度和季节性物候模式与早期在宾夕法尼亚州进行的研究中的相似。两项研究中鉴定出的最丰富的物种包括天牛霉素 Elaphidion mucronatum (Say)、Neoclytus acuminatus acuminatus (F.)、Neoclytus mucronatus mucronatus (F.) 和 Xylotrechus colonus (F.)。天牛碱物种从早春到晚秋有序地活跃起来，而大多数苎麻物种在夏季和秋季活跃，而lepturine物种仅限于夏季。季节性活动期的差异和作为同种特异性增效剂、异种特异性拮抗剂或两者兼而有之的次要信息素成分，可能避免了某些共享信息素成分的天马霉素物种之间潜在的交叉吸引力。
