Deroplax silphoides (Thun.) (Hemiptera: Scutelleridae), a new recorded insect species on Dodonaea viscosa (L.), and its egg parasitoid Trissolcus basalis Woll. (Hymenoptera: Scelionidae) in Egypt
Abstract The scutellerid shield bug, Deroplax silphoides (Thun.) (Hemiptera: Scutelleridae), is a new recorded insect species (in Egypt) attacking the ornamental plant, Dodonaea viscosa (L.). The bug feeds by sucking sap from flowers and green seeds of this plant and sometimes from the very tender y...
