捕捉天牛和其他腐皮甲虫的最有效的陷阱是拦截设计，如漏斗陷阱和十字叶片面板陷阱。我们已经观察到，许多种类的天牛成虫经常在面板陷阱上下车和行走，实际上很少被捕获。为了改善诱捕器的捕获和保留，研究人员用Rain-X处理拦截诱捕器，Rain-X是一种聚硅氧烷制剂，使表面更光滑。在这里，我们总结了实验，比较了Rain-X和Fluon，PTFE氟聚合物分散体，作为面板陷阱，部署捕捉天牛甲虫的表面处理的功效，使用未经处理的陷阱作为对照。与Rain-X处理或对照诱捕器相比，经氟处理的诱捕器平均捕获甲虫总数的14倍以上，并且捕获更多的天牛种类。氟处理的陷阱捕获的甲虫不等的体长的350%。他们不能在用Fluon处理过的垂直板上行走，但很容易在用Rain-X处理过的板和未经处理的陷阱上行走。此外，即使在恶劣的天气下，一次Fluon处理在整个田间季节仍然有效。我们的结论是，处理面板陷阱与氟大大提高了捕捉天牛甲虫的效率。当陷阱被用来检测非常低密度的种群时，这种效率的提高将特别重要，例如外来物种的入侵，或稀有和濒危物种的残留群落。氟对捕集器效率的影响可能因产品配方及其来源以及气候条件而异。
The most effective traps for capturing cerambycids and other saproxylic beetles are intercept designs such as funnel traps and cross-vane panel traps. We have observed that adult cerambycids of many species often alight and walk upon panel traps, and few are actually captured. In an effort to improve trap capture and retention, researchers have treated intercept traps with Rain-X, a polysiloxane formulation that renders surfaces more slippery. Here, we summarize experiments that compared the efficacies of Rain-X and Fluon, a PTFE fluoropolymer dispersion, as surface treatments for panel traps that are deployed to capture cerambycid beetles, using untreated traps as controls. Fluon-treated traps captured on average >14X the total number of beetles, and many more cerambycid species, than were captured by Rain-X-treated or control traps. Beetles captured by Fluon-treated traps ranged in body length by 350%. They could not walk on vertical panels treated with Fluon but easily walked on those treated with Rain-X and on untreated traps. Moreover, a single Fluon treatment remained effective for the entire field season, even in inclement weather. We conclude that treating panel traps with Fluon greatly improves their efficiency in capturing cerambycid beetles. This increased efficacy will be particularly important when traps are deployed to detect very low-density populations, such as incursions of exotic species, or remnant communities of rare and endangered species. The influence of Fluon on trap efficiency may vary with product formulation and its source and also with climatic conditions.
