Species introduced into new habitats are fitter than their native populations, as hypothesized by the ‘evolution of increased competitive ability’ (EICA). Here, Pereskia aculeata Miller was used as a model to test EICA and explore how ‘enemy release’ may have influenced the invasion success of its 400‐year‐old introduced populations (genotypes) compared with native populations. Plant growth traits (height and shoot length) of 15 genotypes [four from the introduced range (South Africa) and 11 from the native range (Brazil and Argentina, Venezuela and The Dominican Republic)] were assessed. Damage and impact of a shoot‐feeding, sap‐sucking specialist Catorhintha schaffneri Brailovsky & Garcia on ten genotypes were also compared.

侵入性Pereskia aculeata（仙人掌科）生长特性的演变：使用其专门的草食动物Catorhintha schaffneri（Coreidae）测试EICA假设。

引入新栖息地的物种比其本地种群更适合，这是由“增强的竞争能力演变”（EICA）所假设的。在这里，Pereskia aculeata Miller被用作测试EICA的模型，并探索“敌人释放”可能如何影响其400岁引进种群（基因型）与本地种群的入侵成功。评估了15个基因型的植物生长性状（高度和苗长）[四个是引入范围的（南非），另一个是11个原生类型的（巴西和阿根廷，委内瑞拉和多米尼加共和国）]。还比较了摄芽，吸吮专家Catorhintha schaffneri Brailovsky＆Garcia对十种基因型的损害和影响。
