Goal: Deliver Benefits to the Public Trapping Methods for Detection of Exotic Hardwood Woodborers
Exotic species of hardwood woodborers continue to threaten forests and economies of the U.S. and necessitate the need for early detection tools. Trap type, color, placement, and numerous lures can all influence captures of diverse groups of woodborers. Our goal is to develop optimal and cost-effective combinations of these factors to maximize our detection capabilities of new beetle invaders.
Various types of traps and lures can enhance detection efficacy of a broad and diverse group of hardwood woodboring beetles. Simple enhancements like doubling the size of holes in funnels or use of alternate traps like the SLAM trap can double or triple catches of beetles. New pheromones for hardwood borers (hydroxyketones and hexanediols) are attractive to numerous species of Cerambycidae in the Georgia Piedmont. Combining these lures can reduce detection costs but does result in loss of detection efficacy for some species. The color of traps can affect captures especially in forest canopies. Traps were deployed in crowns of white oak by tree climbers using single-rope entry techniques. Current trials are focusing on optimal combinations in an operational setting.
