Erythrina gall wasp in Florida (first report in continental U.S.): pest alert
Galls of the eulophid erythrina gall wasp, Quadrastichus erythrinae Kim 2004, were first collected in Florida by Edward Putland and Olga Garcia (Florida Department of Agriculture, Division of Plant Industry) on Erythrina variegata L. in Miami-Dade County at the Miami Metro Zoo on October 15, 2006. The October [ed.: 2006] collection in Miami is the first record of this pest in the continental U.S. Initial limited survey has detected many suspect erythrina gall wasp-infested coral trees throughout Miami-Dade County.

A new parasitoid of the erythrina gall wasp, Quadrastichus erythrinae Kim (Hymenoptera: Eulophidae)
Aprostocetus exertus La Salle (Hymenoptera: Eulophidae: Tetrastichinae) is described as a parasitoid of the invasive erythrina gall wasp, Quadrastichus erythrinae Kim (Hymenoptera: Eulophidae: Tetrastichinae). The description is
based on material originally collected in Tanzania and South Africa. This species is described because of its potential as
a biological control agent against the erythrina gall wasp.

Outbreak of erythrina gall wasp (Hymenoptera: Eulophidae) on Erythrina spp. (Fabaceae) in Taiwan
"The erythrina gall wasp was first recorded damaging coral trees, Erythrina spp. (Fabaceae), in southern Taiwan in 2003; since then it has rapidly spread throughout the island on various species of Erythrina. Galls form on the leaves, petioles, young shoots, and stems. Obvious swelling can be seen on infected tissue parts, and severe infestations cause curling of young shoots, defoliation, and death of the tree. At present, 5 species and a subspecies of coral trees have been recorded as suitable hosts. The gall inducer is Quadrastichus erythrinae Kim (Eulophidae), newly reported in Singapore, Mauritius, and Réunion, and it has also caused severe damage in those areas. In this research, we report the symptoms, the distribution of infested coral trees in Taiwan, identification characteristics of the galler, and pest control suggestions."
