Abstract：
Cotton leafroll dwarf virus (CLRDV) is an emerging aphid-borne pathogen infecting cotton, Gossypium hirsutum L., in the southern United States (U.S.). The cotton aphid, Aphis gossypii Glover, infests cotton annually and is the only known vector to transmit CLRDV to cotton. Seven other species have been reported to feed on, but not often infest, cotton: Protaphis middletonii Thomas, Aphis craccivora Koch, Aphis fabae Scopoli, Macrosiphum euphorbiae Thomas, Myzus persicae Sulzer, Rhopalosiphum rufiabdominale Sasaki, and Smynthurodes betae Westwood. These seven have not been studied in cotton, but due to their potential epidemiological importance, an understanding of the intra- and inter-annual variations of these species is needed. In 2020 and 2021, aphids were monitored from North Carolina to Texas using pan traps around cotton fields. All of the species known to infest cotton, excluding A. fabae, were detected in this study. Protaphis middletonii and A. gossypii were the most abundant species identified. The five other species of aphids captured were consistently low throughout the study and, with the exception of R. rufiabdominale, were not detected at all locations. The abundance, distribution, and seasonal dynamics of cotton-infesting aphids across the southern U.S. are discussed.
摘要：
棉花卷叶矮小病毒(CLRDV)是一种新兴的感染棉花的蚜虫病原体,陆地棉,在美国南部（美国）。棉花蚜虫,AphisgossypiiGlover,每年都会感染棉花，并且是唯一已知的将CLRDV传播到棉花的媒介。据报道，其他七个物种以食物为食，但不经常感染，棉花：Protaphismidletonii托马斯，阿菲斯克拉克科赫，AphisfabaeScopoli,大虹吸管，托马斯，MyzuspersicaeSulzer,RhopalosiphumrufiabdominaleSasaki，和SmynthurodesbetaeWestwood。这七个还没有在棉花中研究过，但是由于它们潜在的流行病学重要性，需要了解这些物种的年际和年际变化。在2020年和2021年，使用棉田周围的平底锅陷阱对从北卡罗来纳州到德克萨斯州的蚜虫进行了监测。所有已知感染棉花的物种，不包括A.fabae，在这项研究中被检测到。midletonii和A.gossypii是鉴定出的最丰富的物种。在整个研究过程中，捕获的其他五种蚜虫一直很低，除了R.rufiabdominale,没有在所有地点检测到。丰富，分布，并讨论了美国南部棉花蚜虫的季节性动态。
