Lysiphlebus testaceipes (Cresson) is a beneficial parasite of greenbug in the field but can be a pest when screening small grains and sorghum in the greenhouse for resistance to the greenbug. The parasite can interfere by reducing greenbug populations needed to show damage to susceptible entries. Caged studies showed that Charips sp. could reduce the level of L. testaceipes to basically that of the control where no primary parasites were present. Observations have shown control in open greenhouses as well. Pachyneuron siphonophorae (Ashmead) could be used to complement Charips sp. in a practical control program.
