Citrus greening disease is a devastating disease of citrus transmitted by two different psyllids, Diaphorina citri (a species of Asian origin) and Trioza erytreae (a species of African origin). D. citri was first found in Florida during 1998. During 2005, greening disease was discovered in Florida. Therefore, the entire North American citrus industry is at risk of the disease. T. erytreae is not known to occur in the New World. This presentation will review the biology and ecology of the two psyllid species.


Species 1: Hemiptera Psyllidae Diaphorina citri (Asian citrus psyllid)
Species 2: Hemiptera Psyllidae Trioza erytreae (African citrus psylla)
