R. Sobhian, 2 BIOTYPES OF BANGASTERNUS-ORIENTALIS (COLEOPTERA, CURCULIONIDAE) FOUND IN GREECE, Proceedings of the Entomological Society of Washington, 95(2), 1993, pp. 163-164
Adults of Bangasternus orientalis (Capiomont) were collected on Centau
rea calcitrapa L., purple starthistle (PST) and C. solstitialis L., ye
llow starthistle (YST) in Greece. The adults collected on YST did not
breed on PST and the adults collected on PST did not breed on YST, ind
icating that they are two biotypes, each one specialized on one Centau
rea species.
