Abstract

The biology of Cassida hemisphaerica Hbst. (Coleoptera: Chrysomelidae) is given and its suitability as a biological control agent of bladder campion, Silene cucubalus Wibel, is evaluated. Because its host range includes a number of ornamental plants in the genus Dianthus and the adults will feed on economic plants in the family Chenopodiaceae, introduction of C. hemisphaerica is not at this time justified.
