The sugarcane aphid, Melanaphis sacchari (Zehntner), emerged as a severe pest of sorghum, Sorghum bicolor (L.), in Texas and Louisiana in 2013 and currently threatens nearly all sorghum production in the United States. Proper management of populations is critical as sugarcane aphid has a high reproductive potential and can rapidly damage plants, resulting in extensive yield losses. The overall objective of this work was to investigate sugarcane aphid population dynamics, and subsequent sorghum injury and grain yield on commercially available grain sorghum varieties in Alabama. This research includes three-site years of data that show variation in plant injury, physiological maturity, and yields among varieties tested. Although performance of each variety was variable among locations, potentially due to abiotic factors, four varieties including DKS 37-07, 1G588, 1G855, and 83P17 exhibited characteristics consistent with resistance and corroborates reports of resistance from other states.

评估阿拉巴马州商业高粱品种中的甘蔗蚜虫、Melanaphis sacchari(半翅目:蚜科)、种群动态、摄食损伤和粮食产量



甘蔗蚜 Melanaphis sacchari (Zehntner) 于 2013 年在德克萨斯州和路易斯安那州成为高粱 (Sorghum bicolor (L.)) 的严重害虫,目前威胁着美国几乎所有高粱生产。适当的种群管理至关重要,因为甘蔗蚜虫具有很高的繁殖潜力,可以迅速损害植物,导致广泛的产量损失。这项工作的总体目标是调查阿拉巴马州市售高粱品种的甘蔗蚜虫种群动态以及随后的高粱损伤和粮食产量。这项研究包括三个地点的年份数据,这些数据显示了所测试品种之间植物损伤、生理成熟度和产量的差异。尽管每个品种的性能因地点而异,可能是由于非生物因素,但包括 DKS 37-07、1G588、1G855 和 83P17 在内的四个品种表现出与抗性一致的特征,并证实了其他州的抗性报告。
