“…One of the most potent threats in raising sorghum yield potential is insect damage; more than 150 insect species have been found negatively to affect worldwide sorghum production (Wang et al., 2013). Of these, Melanaphis sacchari causes the most serious damage to sorghum and sugarcane (Lahiri et al., 2021; Uchimiya & Knoll, 2019). Numerous investigations have identified candidate genes that confer resistance to this pest.…”

The sorghum aphid (Melanaphis sacchari) has emerged as a serious pest for Sorghum bicolor and a major factor limiting its production worldwide. In this study, whole‐genome resequencing of resistant and susceptible bulks from a recombinant inbred line (RIL) population was conducted together with transcriptome analysis of the parent to identify genes underlying aphid resistance. In the NGS‐based bulked segregation analysis (BSA), using a total of 920,389 genome‐wide high‐confidence markers, four QTLs, qtlMs‐6.1, qtlMs‐6.2, qtlMs‐6.3, and qtlMs‐6.4, were identified on chromosome 6. Based on comparative transcriptome analysis, 245 differentially expressed genes (DEGs,190 upregulated and 55 downregulated) and 576 DEGs (336 upregulated and 240 downregulated) were identified at 4 dpi in 407B (resistant) and 7B (susceptible), respectively. The DEGs in 407B were enriched in ‘DNA replication’, ‘flavone and flavonol biosynthesis’ and ‘flavonoid biosynthesis’, which are associated with plant stress resistance. The QTL‐seq study identified a SNP marker (Chr6: 2686447C>G) that was validated on a diverse panel and could be used in molecular marker‐assisted selection to improve aphid resistance in sorghum.

“…Host plant resistance is an economical and reliable management tool ( Painter 1951 , Starks and Schuster 1976 , Teetes 1996 ) that has been widely adapted for sorghum aphid pests like the greenbug, Schizaphis graminum Rondani (Hemiptera: Aphididae) ( Schuster and Starks 1973 , Morgan et al 1980 , Starks et al 1983 , Dixon et al 1990 ), and more recently, sugarcane aphid ( Armstrong et al 2015 , 2017 ; Bowling et al 2016b; Mbulwe et al 2016 ; Brewer et al 2017 ; Szczepaniec 2018a , b ; Haar et al 2019 ; Hayes et al 2019 ; Lahiri et al 2019 ; Paudyal et al 2019 ). Resistant varieties provide a baseline of protection against insects by suppressing population growth rates and reducing plant injury and yield losses.…”

“…Resistant varieties provide a baseline of protection against insects by suppressing population growth rates and reducing plant injury and yield losses. Host plant resistance that decreases populations and/or population growth has been identified in several grain sorghum breeding lines ( Armstrong et al 2015 , 2017 ; Mbulwe et al 2016 ; Hayes et al 2019 ) and commercial varieties ( Bayoumy et al 2016 ; Brewer and Gordy 2016 ; Brown and Kerns 2016 ; United Sorghum Checkoff Program 2016 ; Brewer et al 2017 ; Kelley 2017 ; Michaud and Zuckoff 2017 ; Szczepaniec 2018a , b ; Haar et al 2019 ; Lahiri et al 2019 ; Paudyal et al 2019 ), but performance of these varieties is geographically variable. The underlying mechanisms responsible for sorghum resistance to sugarcane aphid are currently unknown ( Szczepaniec 2018a ); however, research has shown that the phenological stage and nutrient content during initial infestation can significantly influence sugarcane aphid fecundity on resistant varieties ( Lama et al 2019 ).…”

“…Although host plant resistance alone does not prevent populations from reaching damaging levels, suppression of plant injury or population growth rates of sugarcane aphids may increase economic threshold levels for sorghum varieties with high resistance ( Ahrens et al 2014 , Bowling et al 2016a , Brewer et al 2016 , Szczepaniec 2018b , Trostle et al 2018 ). This may give farmers a longer treatment window to make a foliar insecticide application, potentially reduce the number of insecticide sprays, and promote efficacy of biological control agents ( Bowling et al 2016a ; Colares et al 2015a , b ; Haar et al 2018 , 2019 ; Lahiri et al 2019 ).…”

Evaluating Sugarcane Aphid, Melanaphis sacchari (Hemiptera: Aphididae), Population Dynamics, Feeding Injury, and Grain Yield Among Commercial Sorghum Varieties in Alabama

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.

Forage sorghum (Sorghum bicolor L.) grown for silage production is frequently infested by the sugarcane aphid (SCA; Melanaphis sacchari [Zehntner] [Hemiptera: Aphididae]). The objective of this study was to establish first-time action thresholds for SCA infestation, leaf feeding, honeydew, and/or dead leaves. In this 2-yr Texas High Plains study, we quantified the impact of varying densities of SCA and subsequent damage beginning at boot stage to yields and silage nutritive value of a susceptible forage sorghum hybrid (Pioneer 841F) by using untreated controls and different insecticide treatments (lambda cyhalothrin, chlorpyrifos, malathion, and flupyradifurone). Aphid damage occurred from boot to flowering growth stages. Damaging infestations continued until harvest in 2017, but SCA densities declined sharply after peaking at the beginning milk growth stage (BMS) in 2019. Damage levels were significantly correlated to increases in aphid densities at BMS (R 2 = .91) in 2017 and at 50% bloom (R 2 = .83) and BMS (R 2 = .86) in 2019. Yield losses increased with increasing damage at the BMS in 2017 (R 2 = .82) and 2019 (R 2 = .42). Reductions in nutritive value were correlated to yield reductions. Results indicate that SCA infestations should be controlled when ≥20% of the leaf area is infested and damaged at BMS to prevent yield and nutritive value losses in the fresh and ensiled forage.Based on this work, an action threshold for forage sorghums to minimize losses to yield, nutritive value, and economic returns is presented.
