Trapping system for longhorn beetles at the Coweeta Hydrologic Laboratory from 2000 to 2003

This was a pheromone trapping experiment for bark and wood boring beetles. The study attempts to develop an efficient trapping system for the detection and monitoring of exotic bark and wood boring beetles, particularly longhorn beetles (Cerambycidae). It was conducted from 12 May 2003 to 30 July 2003 in mature white pine stand with lots of tree mortality to southern pine beetle, Dendroctonus frontalis. There were four replicates of eight treatments set in RBD with four replicates at each of two sites. Treatments involved funnel traps baited with combinations of three common bark beetle pheromones: lanierone, ipsenol and ipsdienol. The objective is to use areas in the south with substantial populations of native beetles to develop a generic trap for large wood borers before attempting trials in areas such as China and Russia. Several types of intercept traps will be tested with various host compounds such as ethanol and alpha-pinene.本实验为针对树皮甲虫与蛀木甲虫的信息素诱捕试验。本研究旨在开发一套高效诱捕系统，用于检测与监测外来入侵的树皮甲虫和蛀木甲虫，尤以天牛科（Cerambycidae）甲虫为核心监测对象。试验于2003年5月12日至2003年7月30日期间开展，实施地点为一片因南方松小蠹（Dendroctonus frontalis）造成大量树木死亡的成熟白松林。本试验采用随机区组设计（Randomized Block Design, RBD），共设置8种处理方式，每种处理设置4次生物学重复，两个试验点各配置4组重复。各处理组均采用由lanierone、ipsenol与ipsdienol三种常见树皮甲虫信息素组合配制的诱芯搭配漏斗诱捕器。本研究的目标为：依托北美南部地区本土甲虫种群丰富的区域条件，在前往中国、俄罗斯等地区开展野外试验前，开发一款适用于大型蛀木甲虫的通用诱捕系统。后续本研究还将测试多款拦截式诱捕器，搭配乙醇、α-蒎烯等多种寄主源化合物开展验证试验。
