Greenhouse-grown cucurbit crops in several Iranian regions were surveyed for the incidence of Cucumber mosaic virus (CMV), Squash mosaic virus (SqMV), Papaya ring spot virus-type W (PRSV-W), Watermelon mosaic virus-2 (WMV-2), Zucchini yellow mosaic virus (ZYMV), Cucumber necrosis virus (CuNV) and Tomato spotted wilt virus (TSWV) from September 2002 to June 2004. In all, 1,304 random and 1,085 symptomatic leaf or fruit samples were collected. Samples were analyzed for virus infection by enzyme-linked immunosorbent assay. CMV and ZYMV were the viruses most frequently detected, accounting for 21.2 and 18% of the infected plants, respectively. WMV-2 was detected with 4.3% incidence in 15 regions and TSWV with 1.25% incidence only in 2 regions. CuNV, SqMV, and PRSV-W were not detected in any samples. Double and triple infections involving different combinations of CMV, ZYMV, WMV-2, and TSWV were noted in 117 and 4 samples, respectively. Natural infection of cucumber with TSWV and ZYMV is reported for the first time from Iran. Of 16 plant species from 14 genera, growing in or around greenhouse facilities, 6 were found infected with ZYMV, TSWV, WMV-2, and CMV and may act as reservoirs of the viruses. Four species are reported as new hosts of these viruses.
2002年9月至2004年6月，对伊朗几个地区温室种植的葫芦科作物进行了调查，以了解黄瓜花叶病毒（CMV）、南瓜花叶病毒（SqMV）、番木瓜环斑病毒W型（PRSV-W）、西瓜花叶病毒2型（WMV-2）、小西葫芦黄花叶病毒（ZYMV）、黄瓜坏死病毒（CuNV）和番茄斑萎病毒（TSWV）的发生率。总共采集了1304份随机样本以及1085份有症状的叶片或果实样本。通过酶联免疫吸附测定法对样本进行病毒感染分析。CMV和ZYMV是最常检测到的病毒，分别占受感染植株的21.2%和18%。在15个地区检测到WMV-2，发生率为4.3%，仅在2个地区检测到TSWV，发生率为1.25%。在任何样本中均未检测到CuNV、SqMV和PRSV-W。分别在117个和4个样本中发现了涉及CMV、ZYMV、WMV-2和TSWV不同组合的双重和三重感染。伊朗首次报道黄瓜自然感染TSWV和ZYMV。在温室设施内或周边生长的14个属的16种植物中，发现6种感染了ZYMV、TSWV、WMV-2和CMV，可能充当这些病毒的宿主库。报道了4种植物为这些病毒的新宿主。
