摘　　要：通过调查研究,摸清了深圳刺桐种类,明确了深圳不同地区刺桐被害程度和刺桐姬小蜂对不同刺桐种类危害程度的差异,结果表明,刺桐受害程度由重到轻的顺序为刺桐、龙牙花、金脉刺桐、鸡冠刺桐、火炬刺桐、劲直刺桐,象牙花、矮刺桐由于分布和数量极其有限,没有发现受害。研究结果可为合理利用刺桐控制刺桐姬小蜂提供参考。Investigations and samples about Erythrina species and Erythrina gallwasp Quadrastichus erythrinae were carried out in Shenzhen.The results revealed that there were 8 species and varieties of Erythrina spp.in Shenzhen,including E.caffra,E.variegata,E.crista-galli,E.variegata var.orientialis,E.corallodendron,E.stricta,E.speciosa and E.humeana.Levels of Erythrina gallwasp infestations on different Erythrina species were obviously different.Levels of Erythrina gallwasp infestations on E.variegata,E.corallodendron,E.variegata var.orientialis,E.crista-galli,E.caffra,and E.stricta decreased,and No damage of Erythrina gallwasp to E.speciosa,E.humeana were found.
