中文摘要：南瓜黄色矮化失调病毒(CYSDV)是由烟粉虱传播的，可导致亚利桑那州尤马县秋季甜瓜严重减产。最近基于景观的研究发现了棉花和春季甜瓜地里的烟粉虱丰富度增高，秋季甜瓜地里CYSDV侵染传播速度提高。本文对统计模型的验证表明，虽然棉花隔离可能比春季甜瓜隔离能够提供更一致的利益，但作物隔离可能会减少CYSDV侵染在尤马县秋季甜瓜地里的发生率。
外文摘要：The cucurbit yellow stunting disorder virus (CYSDV) transmitted by Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) has caused significant reductions in fall melon (Cucumis melo L.) yields in Yuma County, Arizona. In a recent landscape-based study, we found evidence that cotton and spring melon fields increased abundance of B. tabaci and spread of CYSDV infection in fall melon fields. Here, we show that a statistical model derived from data collected in 2011-2012 and based on areas of cotton and spring melon fields located within 1,500 m from edges of fall melon fields was sufficient to retrospectively predict incidence of CYSDV infection in fall melon fields during 2007-2010. Nevertheless, the slope of the association between areas of spring melon fields and incidence of CYSDV infection was three times smaller in 2007-2010 than in 2011-2012, whereas the slope of the association between areas of cotton fields and incidence of CYSDV infection was consistent between study periods. Accordingly, predictions were more accurate when data on areas of cotton alone were used as a basis for prediction than when data on areas of cotton and spring melons were used. Validation of this statistical model confirms that crop isolation has potential for reducing incidence of CYSDV infection in fall melon fields in Yuma County, although isolation from cotton may provide more consistent benefits than isolation from spring melon.
