Impact of Planting Date on Melanaphis sacchari (Hemiptera: Aphididae) Population Dynamics and Grain Sorghum Yield

Abstract: The sugarcane aphid, Melanaphis sacchari (Zehntner) (Hemiptera: Aphididae), has become a major pest of grain sorghum, Sorghum bicolor (L.) Moench, in the United States in recent years. Feeding by large densities of sugarcane aphids causes severe damage, which can lead to a total loss of yield in extreme cases. Our objective was to determine the effect of grain sorghum planting date on sugarcane aphid population dynamics and their potential to reduce yields. We conducted field experiments from 2015 to 2017 in w… Show more

“…They theorized that this was due to higher aphid densities. Shifting the planting date did not change the timeframe of infestation but solely the growth stage of the crop when the infestation occurred (Haar, 2018; Seiter et al., 2019). This emphasizes the potential of using planting date to aid in the management of sugarcane aphid, as up to 100% yield loss has been documented when sugarcane aphids infest at late vegetative to early reproductive growth stages compared with only 21% by soft dough (Catchot et al., 2015).…”
