中文摘要	Erythrina gall wasp, Quadrastichus erythrinae Kim, was first described in 2004. It has become a gall-inducing invader and can result in the death of Erythrina trees in affected areas. The most serious aspect of the threat was its enormous expansion rate and sudden outbreaks. The aim of this paper is to predict the potential geographical distribution of erythrina gall wasp on a global scale. The Genetic Algorithm for Rule-Set Prediction (GARP) was used to analyze its potential expansion based on occurrence records and environmental data. The results indicate that Q. erythrinae will affect wide areas of Asia, Africa, Oceania, South America, and reach the southern part of North America. The predicted potential range is far-reaching and pan-tropical, and includes tropical rainforest, tropical monsoon, subtropical monsoon and tropical savannah climates. Vegetation types and humidity are predicted to be limiting factors for its spread. Based on the currently reported distribution pattern and predicted ranges of expansion of the erythrina gall wasp, it is possible that Africa was the area of origin.
