oa Journal of the Entomological Society of Southern Africa - The biology and host plant specificity of Acanthoplus speiseri Brancsik (Orthoptera : Tettigoniidae : Hetrodinae), a pest of grain crops



The biology of the armoured ground cricket, Acanthoplus speiseri Brancsik, a pest of maize and sorghum in Zambia, was studied in the field and in the laboratory. A. speiseri fed on a number of grasses and on a single species from each of the families Asteraceae and Solanaceae. The cultivated plants, Zea mays L., and Sorghum vulgare Pers., were also fed upon although no conspicuous concentrations of crickets were found on these plants.
