Developing a host attractant lure and determining the optimal trap for Sirex spp. in North America
Researchers: L.J. Haavik, J.D. Allison, K.J. Dodds, J.R. Meeker, and W. Johnson
We plan to identify, synthesize, and test an effective lure/trap combination for attracting Sirex spp. We will test the efficacy of pine bag lures in attracting Sirex spp. among several pine species that grow in the northeastern U.S. and Canada. We will collect volatiles from foliage and wood chips of the same Pinus spp. and analyze them by GC-EAD and GC-MS to identify putative attractants. We will also examine the effect of intercept trap design (e.g. 12-unit modified multiple-funnel, 12-unit multiple-funnel, panel) on Sirex spp. trap captures. Using the most effective trap type, we will test the ability of synthetic sources of these putative attractants alone, and in combination with pheromones, to attract Sirex spp. in the field.
