The Asian citrus psyllid (Diaphorina citri) is a major insect pest of citrus cultivars, though it may also feed on a wide range of alternative host plants. Recent research has identified the plant Cordia myxa as another alternate host, and researchers are evaluating whether C. myxa might have potential as a trap crop for use in Asian citrus psyllid management.
