Dichelops melacanthus Dallas, 1851

This green-belly stink bug is found in South and Central America. It has been regarded as rare before 1990, but has become a serious pest of soybean, maize, and wheat crops, mainly in southern Brazil and Argentina. Other types of crops may also be attacked. The adults and nymphs feed on seedlings and on the developing pods, ears and seed heads of their host plants. In a laboratory choice test, immature soybean pods were the preferred food (Chocorosqui & Panizzi, 2008).
