Fluon PTFE is a fluoropolymer dispersion applied as a surface conditioner to cross-vane panel traps to enhance trap efficiency for cerambycid beetles. We describe the results of three experiments to further optimize cerambycid traps of different designs and to test the effect of Fluon over time. We tested Fluon with Lindgren funnel and panel traps fitted with either wet or dry collection cups on catches of cerambycid beetles and how the effect of Fluon on panel traps persisted. Fluon-treated funnel traps with wet collection cups captured approximately 6x more beetles than the untreated funnel traps with wet collection cups. Untreated funnel traps with dry collection cups did not capture any beetles; however, Fluon-treated funnel traps with dry collection cups captured an average of four beetles per trap. Fluon-treated panel traps with wet collection cups captured approximately 9x more beetles than untreated panel traps with wet collection cups. Fluon-treated panel traps with dry collection cups captured approximately 11x more beetles than untreated panel traps with dry collection cups. The effect of Fluon on capturing cerambycid beetles did not decline after use in one or two field seasons. There was no significant difference in the number of beetles captured in freshly treated panel traps compared with traps that had been used for 1 or 2 yr. Fluon-treated traps captured nine species that were not captured in untreated traps. Conditioning both Lindgren funnel and panel traps with Fluon enhances the efficacy and sensitivity of traps deployed to detect exotic cerambycid species, or for monitoring threatened species at low population densities.
氟隆 PTFE 是一种氟聚合物分散体，作为表面调节剂应用于交叉叶片面板陷阱，以提高对天牛科甲虫的陷阱效率。我们描述了三个实验的结果，以进一步优化不同设计的天牛科陷阱，并测试 Fluon 的时效。我们测试了带有林德格伦漏斗和带有湿或干收集杯的面板陷阱的 Fluon，以及 Fluon 对面板陷阱的效果持久性。带有湿收集杯的氟隆处理漏斗陷阱捕获的甲虫数量约比带有湿收集杯的未处理漏斗陷阱多 6 倍。带有干收集杯的未处理漏斗陷阱没有捕获到任何甲虫；然而，带有干收集杯的氟隆处理漏斗陷阱平均每只陷阱捕获了 4 只甲虫。带有湿收集杯的氟隆处理面板陷阱捕获的甲虫数量比带有湿收集杯的未处理面板陷阱多约 9 倍。带有干收集杯的氟隆处理面板陷阱捕获的甲虫数量比带有干收集杯的未处理面板陷阱多约 11 倍。氟隆处理在一个或两个野外季节后对捕获天牛科甲虫的效果没有下降。与使用了 1 年或 2 年的陷阱相比，新处理的面板陷阱中捕获的甲虫数量没有显著差异。氟隆处理的陷阱捕获了 9 种在未处理的陷阱中未捕获的物种。用 Fluon 对林德格伦漏斗和面板陷阱进行处理，可以提高用于检测外来天牛科物种或监测低种群密度下受威胁物种的陷阱的效果和灵敏度。
