摘　　要：将刺桐枝条的受害程度划分为6个等级,调查刺桐姬小蜂Quadrastichus erythrinae对刺桐、刺桐东方变种、黄脉刺桐、龙牙花和鸡冠刺桐的危害程度。Ridit分析结果表明,刺桐东方变种受害最严重,其次为金脉刺桐,刺桐不受害。这一研究结果可为合理引种刺桐控制刺桐姬小蜂的扩散和为害提供参考。Field trials and sampling of erythrina species were carried out in Pearl River Delta of China to assess the impact of erythrina gall wasp （ EGW）, Quadrastichus erythrinae, on five erythrina species. The EGW infestation were classified into six levels by the leaf damage and the gall types. The result of Ridit analysis showed the levels of infestation were Erythrina variegata var. orientalis 〉 E. variegata cv. ‘ Parcellii＇ 〉 E. corallodendron 〉 E. cristagalli 〉 E. variegata. E. variegata was not infested. This provided reference for the reasonable introduction of erythrinas to prevent the spread and damage of EGW.
