Abstract: This paper investigated the occurrence and damage characteristics of erythrina gall wasp (Quadrastichus erythrinae) on five Erythrina species (E. variegate var. orientalis, E. variegate var. orientalis cv. golden vein, E. corallodendron, E. variegate, and E. cristagalli) in Wutong Mountain Forest Farm, Binzhou Crossroads of Xinzhou Futian District, and Bijia Hill Park in Shenzhen. Among the five Erythrina species, E. variegate var. orientalis and E. variegate var. orientalis cv. golden vein were seriously damaged by Q. erythrinae, E. corallodendron was damaged slightly, while native species E. variegate and E. cristagalli were not damaged. At different positions of E. variegate var. orientalis canopy, the leaves at east position had a higher percentage of damage grade III, and their injured index was significantly different from that of the leaves at mid position. In the canopies of E. variegate var. orientalis and E. variegate var. orientalis cv. golden vein, Q. erythrinae preferred the upper leaves.
