In North America, cerambycid beetles can have significant ecological and economic effects on forest ecosystems, and the rate of introduction and/or detection of exotic species is increasing. Detection and survey programs rely on semiochemical-baited intercept traps which are often ineffective for large woodborers like cerambycid beetles. This study examined the effects of flight intercept trap design on the capture of cerambycid beetles in the subfamilies Lamiinae and Cerambycinae. These subfamilies are the two largest in the Cerambycidae and they include many of the most damaging cerambycid pests and species on regulatory watch lists in North America. This study demonstrates that intercept trap design, treatment of trap surfaces with a lubricant, and the type of collection cup all influence the capture of beetles from the subfamilies Lamiinae and Cerambycinae. It also demonstrates that the addition of a large lubricant-treated collar to the bottom funnel of a multiple-funnel trap significantly increases the capture of some Lamiinae. The best trap design for both subfamilies was a lubricant treated multiple-funnel [MF] trap equipped with a wet cup and lubricant treated large collar on the bottom funnel. This design captured between 4 and 14 times more Lamiinae and Cerambycinae than commercially-available MF and panel traps.
在北美，天牛对森林生态系统会产生重大的生态和经济影响，而且外来物种的引入和/或发现率正在上升。检测和调查项目依赖于用信息素诱饵的拦截式诱捕器，但这种诱捕器对于像天牛这样的大型蛀木害虫往往效果不佳。本研究考察了飞行拦截式诱捕器的设计对沟胫天牛亚科和天牛亚科天牛捕获量的影响。这两个亚科是天牛科中最大的两个亚科，包含了许多北美监管观察名单上最具破坏性的天牛害虫和物种。本研究表明，拦截式诱捕器的设计、用润滑剂处理诱捕器表面以及收集杯的类型都会影响沟胫天牛亚科和天牛亚科天牛的捕获量。研究还表明，在多漏斗诱捕器的底部漏斗上添加一个经润滑剂处理的大颈圈可显著增加一些沟胫天牛亚科天牛的捕获量。对于这两个亚科来说，最佳的诱捕器设计是一个经润滑剂处理的多漏斗[MF]诱捕器，配备一个湿杯，并在底部漏斗上有一个经润滑剂处理的大颈圈。这种设计捕获的沟胫天牛亚科和天牛亚科天牛比市售的MF诱捕器和平板诱捕器多4至14倍。
