Increased diseases outbreaks in Gmelina arborea (melina) are a threat to sustainability of commercial plantations. One main disease, known as 'melina sudden death', limits the growth and development of trees, causing losses of up to 40% in commercial plantation. However, the main cause of this disease was unknown, until now. Proof of Ceratocystis fimbriata as the aetiological agent of 'melina sudden death' is provided based on field records of disease symptoms, histopathological observation of infected tissue, morphological features of the fungus, maximum‐likelihood phylogenetic inference of the ITS rDNA sequences and pathogenicity test conducted on GENFORES elite melina genotypes. Thus, the appropriate name for the disease should be Ceratocystis wilt. As far as we know, this is the first report of Ceratocystis wilt in melina caused by Ceratocystis fimbriata in Central America. This disease represents a serious threat to Costa Rica's forest industry, as well as in other Latin American countries.

Ceratocystis fimbriata引起哥斯达黎加Gmelina arborea枯萎的首次报道

Gmelina arborea（melina）疾病暴发的加剧对商业种植园的可持续性构成了威胁。一种主要的疾病被称为“ melina突然死亡”，它限制了树木的生长和发育，在商业人工林中造成的损失高达40％。然而，直到现在，这种疾病的主要原因尚不清楚。纤维状角藻的证明根据疾病症状的现场记录，感染组织的组织病理学观察，真菌的形态特征，ITS rDNA序列的最大似然系统发育推断以及在GENFORES精英melina上进行的致病性测试，提供“ melina突然死亡”的病因基因型。因此，该疾病的适当名称应为青枯萎病。据我们所知，这是中美洲由纤毛虫（Ceratocystis fimbriata）引起的黑斑病中的Ceratocystis枯萎的首次报道。这种疾病对哥斯达黎加以及其他拉丁美洲国家的林业产业构成了严重威胁。
