The main areas for field-grown melon (Cucumis melo) production in Spain were surveyed for the occurrence and relative incidence of cucumber mosaic virus (CMV), papaya ringspot virus-watermelon strain (PRSV-W), watermelon mosaic virus-2 (WMV-2), and zucchini yellow mosaic virus (ZYMV) during the growing seasons of 1995 and 1996. Samples from 1,152 plants showing symptoms of virus infection were collected from commercial melon fields and analyzed by enzyme-linked immunosorbent assay (ELISA). CMV and WMV-2 were the most frequently found viruses, both by the number of locations and by their incidence in each location. In contrast, PRSV-W and ZYMV were detected in fewer sites and at lower incidences. PRSV-W was not found in 1996. In 79% of the samples, only one virus was detected; 15% of the samples were doubly infected. Both the incidence of plants showing symptoms of viral infection and the relative incidence of each of the four viruses varied according to the region, while the main trends of virus distribution were similar for 1995 and 1996.
在1995年和1996年的生长季节，对西班牙露地甜瓜（甜瓜属）的主要种植区域进行了调查，以了解黄瓜花叶病毒（CMV）、番木瓜环斑病毒西瓜株系（PRSV-W）、西瓜花叶病毒2型（WMV-2）和西葫芦黄花叶病毒（ZYMV）的发生情况及相对发病率。从商业甜瓜田采集了1152株有病毒感染症状的植株样本，并通过酶联免疫吸附测定（ELISA）进行分析。无论是从发现病毒的地点数量还是从每个地点的发病率来看，CMV和WMV-2都是最常发现的病毒。相比之下，PRSV-W和ZYMV在较少的地点被检测到，发病率也较低。1996年未发现PRSV-W。在79%的样本中，仅检测到一种病毒；15%的样本受到双重感染。表现出病毒感染症状的植株发病率以及四种病毒各自的相对发病率均因地区而异，而1995年和1996年病毒分布的主要趋势相似。
