Abstract

A survey of cucurbits grown in South Florida was conducted from 2020-2022 for viruses. A total of 481 plant samples (470 cucurbit and 11 non-cucurbit) included watermelon, squash, cantaloupe, cucumber, zucchini, five weeds commonly found in cucurbit fields, cowpea, and two vegetable volunteer plants growing in a watermelon field. Samples were tested for cucurbit chlorotic yellows virus (CCYV), squash vein yellowing virus (SqVYV), papaya ringspot virus-W (PRSV-W), watermelon crinkle leaf-associated virus 1 (WCLaV-1), watermelon crinkle leaf-associated virus 2 (WCLaV-2), cucurbit yellow stunting disorder virus (CYSDV), and cucurbit leaf crumple virus (CuLCrV). All seven viruses were detected with WCLaV-1 as the predominant virus found in cucurbits, followed by CYSDV and WCLaV-2. The majority of samples were mixed infections containing two or more viruses. Host tissue testing found the peduncle was a good source for testing for all viruses. Host symptoms were variable on leaves for WCLaV-1 and WCLaV-2 and in mixed infections with the other five viruses. More studies are required to ascertain the role of WCLaV-1 and WCLaV-2 in mixed infections and their effect on plant health, fruit quality, and yield.

西瓜皱叶病毒1、西瓜皱叶病毒2和其他病毒在南佛罗里达葫芦中的分布和发病率

从2020年到2022年，对南佛罗里达州种植的葫芦进行了病毒调查。总共有481种植物样本(470种葫芦类和11种非葫芦类)，包括西瓜、南瓜、哈密瓜、黄瓜、西葫芦、五种在葫芦地里常见的杂草、豇豆和两种在西瓜地里的蔬菜志愿者植物。对样品进行了瓜绿黄病毒(CCYV)、南瓜静脉变黄病毒(SqVYV)、木瓜环斑病毒- w (prv - w)、西瓜皱叶相关病毒1 (WCLaV-1)、西瓜皱叶相关病毒2 (WCLaV-2)、瓜黄发育障碍病毒(CYSDV)和瓜叶皱缩病毒(CuLCrV)的检测。7种病毒均以WCLaV-1为主，其次为CYSDV和WCLaV-2。大多数样本是含有两种或两种以上病毒的混合感染。宿主组织检测发现，花梗是检测所有病毒的良好来源。WCLaV-1和WCLaV-2以及与其他五种病毒混合感染时，叶片上的宿主症状是可变的。需要更多的研究来确定WCLaV-1和WCLaV-2在混合侵染中的作用及其对植物健康、果实品质和产量的影响。
