The Cerambycidae comprise a large and ecologically important family of wood-boring beetles. The purpose of this study was to examine the effectiveness of a generic lure as a potential monitoring tool. Working in a subtropical forest in southwest China, we set traps baited with generic lures at ground level (1 m) and canopy height (~18 m) across 22 randomly located forest plots (12 regenerating forest, 10 mature forest). Three stations were established per plot and each plot was trapped for 7 days in May-June 2013. In total, 4541 beetles of 71 species were caught, including 26 species with 10 or more individuals. We used Hierarchical Modeling of Species Communities (HMSC) to analyze the data and produced informative models for 18 species, showing that trap height, slope, elevation, and leaf-area index were important determinants of cerambycid distribution. Our results demonstrate the potential for using generic lures to detect and monitor cerambycid populations, both for regulatory purposes and for the study of cerambycid beetle ecology. Further research should focus on refining lure blends, and on repeated sampling to determine temporal and spatial dynamics of cerambycid communities.
天牛科是一类大型且具有重要生态意义的蛀木甲虫家族。本研究的目的是检验一种通用诱饵作为潜在监测工具的有效性。在中国西南部的亚热带森林中开展研究，我们在22个随机定位的森林地块（12个再生林、10个成熟林）的地面（1米）和树冠高度（约18米）设置了用通用诱饵诱捕的陷阱。每个地块设置三个站点，每个地块在2013年5月至6月期间诱捕7天。总共捕获了71种4541只甲虫，其中包括26种个体数量达到或超过10只的甲虫。我们使用物种群落层次模型（HMSC）来分析数据，并为18种甲虫生成了信息丰富的模型，结果表明诱捕高度、坡度、海拔和叶面积指数是天牛分布的重要决定因素。我们的结果证明了使用通用诱饵检测和监测天牛种群的潜力，这对于监管目的以及天牛生态学研究都具有重要意义。进一步的研究应集中在优化诱饵配方，以及通过重复采样来确定天牛群落的时空动态。
