Erythrina gall wasp （Quadrastichus erythrinae Kim） is a new invasive species on coral tree （Erythrina） in resent years. The wasps induces galls on the young shoots, stems, buds, flowers of the coral trees. The Quadrastichus erythrinae Kim has infested and caused damages to several species of Erythrina trees in many countries and regions. The paper summarized briefly the occurrence of this pest in such aspects as life history, life habit, relationship between occurrence and environment, spatial dis- tribution and integrated control. The research tendencies in the future were also discussed in this paper.
