The biology of Trioza erytreae (Del Guercio), African veetor of citrus greening disease, was studied in the field and in an open insectary. Short notes on the life history are given. The incubation period varied from 6-15 days and nymphal development from 17-43 days, both being strongly correlated with mean temperature. Pre-oviposition was usually 3-7 days and longevity 17-50 days.
