In early 2016, hop plants were introduced into Florida. By late 2016, the hop plants were showing stunted growth and were heavily parasitized by . In this study, we determined host susceptibility of 14 hop cultivars to in a greenhouse experiment and monitored population development of plant-parasitic nematode species in the root zone of 17 hop cultivars planted in three newly established hop yards in Florida. Plant-parasitic nematodes in the rooting zone soil of field grown hop plants included , , , , complex, , and however, soil population densities of , , complex, , and remained low through the study. Root galling, egg production, and soil population densities of were consistently large on the 'Canadian Red Vine', 'Centennial', 'Chinook', and 'Comet' cultivars, and small on the 'Galena' and 'Triple Perle' cultivars. No differences were observed in soil population densities of among hop cultivars. Overall, our study provides the first report of plant-parasitic nematode population development in the root zone on hop cultivars planted in Florida.

2016年初，啤酒花植株被引入佛罗里达州。到2016年底，啤酒花植株生长发育不良，并受到[某种寄生虫名称未给出]的严重寄生。在本研究中，我们在温室试验中测定了14个啤酒花品种对[某种寄生虫名称未给出]的寄主易感性，并监测了佛罗里达州三个新建立的啤酒花园中种植的17个啤酒花品种根区植物寄生线虫种类的种群发展情况。田间种植的啤酒花植株根区土壤中的植物寄生线虫包括[多种线虫名称未给出]，然而，在整个研究过程中，[多种线虫名称未给出]的土壤种群密度一直较低。在“加拿大红藤”、“百年纪念”、“奇努克”和“彗星”品种上，根瘤、[某种线虫名称未给出]的产卵量和土壤种群密度一直很大，而在“方铅矿”和“三重珍珠”品种上则很小。在不同啤酒花品种之间，未观察到[某种线虫名称未给出]土壤种群密度的差异。总体而言，我们的研究首次报道了佛罗里达州种植的啤酒花品种根区植物寄生线虫的种群发展情况。2016年初，啤酒花植株被引入佛罗里达州。到2016年底，啤酒花植株生长发育不良，并受到[某种寄生虫名称未给出]的严重寄生。在本研究中，我们在温室试验中测定了14个啤酒花品种对[某种寄生虫名称未给出]的寄主易感性，并监测了佛罗里达州三个新建立的啤酒花园中种植的17个啤酒花品种根区植物寄生线虫种类的种群发展情况。田间种植的啤酒花植株根区土壤中的植物寄生线虫包括[多种线虫名称未给出]，然而，在整个研究过程中，[多种线虫名称未给出]的土壤种群密度一直较低。在“加拿大红藤”、“百年纪念”、“奇努克”和“彗星”品种上，根瘤、[某种线虫名称未给出]的产卵量和土壤种群密度一直很大，而在“方铅矿”和“三重珍珠”品种上则很小。在不同啤酒花品种之间，未观察到[某种线虫名称未给出]土壤种群密度的差异。总体而言，我们的研究首次报道了佛罗里达州种植的啤酒花品种根区植物寄生线虫的种群发展情况。
