Technical Abstract: The leaf beetle Diorhabda elongata Brullé (Coleoptera: Chrysomelidae) is a newly released biological control agent for saltcedars, Tamarix sp., an exotic, invasive weedy tree in the Western U.S. Two pheromone components (2E,4Z-heptadienal and 2E,4Z-heptadien-1-ol) and several six-carbon general green leaf volatiles are highly attractive to the beetles in the field. These compounds have relatively high, but similar volatilities due to their comparable physical properties. However, placed on filter paper odor-cartridges for electrophysiological stimulation, the compounds release rates are very different. The results of a simple stimuli quantitation technique and an electrophysiological dose-response study are presented. The results are discussed in relation to the behavioral responses of the beetles in the field.
