The first records of leaf-feeding on Iva xanthifolia (marsh elder) and Helianthus annuus (common sunflower) by adult Diabrotica barberi are reyorted. During September 1992, beetles were observed feeding on leaves 0 these plants, despite the availability of alternate flowering hosts. Beetles confined to clip cages in the laboratory fed readily on leaves of I. xanthifolia and H. annuus but not on those of Solidago missouriensis (goldenrod).
