Survey and detection programs for native and exotic forest insects frequently rely on traps baited with odorants, which mediate the orientation of target taxa (e.g., the southern pine beetle, Dendroctonusfrontalis Zimmermann) toward a resource (e.g., host material, mates). The influence of trap design on the capture efficiency of baited traps has received far less empirical attention than odorants, despite concerns that intercept traps currently used operationally have poor capture efficiencies for some target taxa (e.g., large woodborers). Several studies have recently demonstrated that treating traps with a surface lubricant to make them "slippery" can increase their capture efficiency; however, previously tested products can be expensive and their application time-consuming. The purpose of this study was to evaluate the effect of alternate, easier to apply aerosol lubricants on trap capture efficiency of selected forest insects. Aerosol formulations of Teflon and silicone lubricants increased both panel and multiple-funnel trap capture efficiencies. Multiple-funnel traps treated with either aerosol lubricant captured significantly more Monochamus spp. and Acanthocinus obsoletus (Olivier) than untreated traps. Similarly, treated panel traps captured significantly more Xylotrechus sagittatus (Germar), Ips calligraphus (Germar), Pissodes nemorensis (Germar), Monochamus spp., A. obsoletus, Thanasimus dubius (F.), and Ibalia leucospoides (Hochenwarth) than untreated traps. This study demonstrates that treating multiple-funnel and panel traps with an aerosol dry film lubricant can increase their capture efficiencies for large woodborers (e.g., Cerambycidae) as well as bark beetles, a weevil, a woodwasp parasitoid and a bark beetle natural enemy (Coleoptera: Cleridae).
调查和检测本地和外来森林昆虫的计划经常依赖于诱饵陷阱，这些陷阱用气味物质来引导目标类群（例如，南方松甲虫，Dendroctonus frontalis Zimmermann）朝着资源（例如，宿主材料，配偶）的方向移动。尽管人们担心目前用于操作的截击陷阱对某些目标类群（例如，大型蛀木虫）的捕获效率较差，但陷阱设计对诱饵陷阱捕获效率的影响受到的关注远不及气味物质。最近的几项研究表明，用表面润滑剂处理陷阱以使它们“光滑”可以提高它们的捕获效率；然而，以前测试的产品可能很昂贵，并且应用起来很耗时。本研究旨在评估替代、更容易应用的气溶胶润滑剂对选定森林昆虫的陷阱捕获效率的影响。特氟龙和硅酮润滑剂的气溶胶配方提高了面板和多漏斗陷阱的捕获效率。用任何气溶胶润滑剂处理的多漏斗陷阱捕获的 Monochamus spp. 和 Acanthocinus obsoletus（Olivier）明显多于未处理的陷阱。同样，处理过的面板陷阱捕获的 Xylotrechus sagittatus（Germar）、Ips calligraphus（Germar）、Pissodes nemorensis（Germar）、Monochamus spp.、A. obsoletus、Thanasimus dubius（F.）和 Ibalia leucospoides（Hochenwarth）明显多于未处理的陷阱。这项研究表明，用气溶胶干膜润滑剂处理多漏斗和面板陷阱可以提高它们对大型蛀木虫（例如，天牛科）以及树皮甲虫、象鼻虫、木蜂寄生蜂和树皮甲虫天敌（鞘翅目：Cleridae）的捕获效率。
