Technical Abstract: The leaf beetle Diorhabda elongata (Coleoptera: Chrysomelidae) is a biological control agent of saltcedar (Tamarix spp.), an invasive shrub found throughout the Western U.S. Identifying behavioral active compounds from saltcedar foliage might result in a better understanding of how D. elongata beetles locate their host plants and attractive saltcedar compounds could also be used as a tool in monitoring the dispersal of the beetles. Current study has identified several saltcedar foliage compounds by using the beetle antenna as sensitive detectors of biological active compounds. Several of these antennally active compounds were highly attractive to the beetles in the field.
