The research proposed is an experiment to test the attractiveness of candidate pheromones of longhorned beetles. Previous research and field testing has indicated that longhorned beetles of different species use pheromones of similar molecular structure. We have produced a variety of isomers of this basic structural theme that we predict are pheromones for different species, but we do not yet know which isomers are used by which species. > The experimental design involves placing a transect of vane and bucket traps 2 m apart. A pheromone emitter will be attached to each trap. Each trap will be treated with a different compound. We will collect beetles from traps every day, and on the last day the traps will be removed. The exact dates of set up are not certain, however, but will be between 20 June and 30 July. We anticipate that the traps will capture no more than thirty beetles of any species, and thus will have little, if any impact on natural populations. > In addition to testing the attractiveness of candidate pheromones, headspace volatiles of beetles collected in the traps will be analyzed to conclusively identify pheromones, histological sections will be made of pheromone release sites to identify pheromone-producing tissues, and specimens will be preserved in ethanol for a phylogenetic study of relationships within the longhorned beetle subfamily Cerambycinae. These data will be included in a dissertation research project which investigates the evolution of chemical communication in the Cerambycidae.
