Differences in Sugarcane Aphid Colonization on Two-Week Old and Six-Week Old Sorghum Plants Influenced by Sugars and Cuticular Waxes

The effectiveness of host plant resistance (HPR) to manage the sugarcane aphid (SCA) in sorghum depends on understanding the timing of the pest in relation to the developmental stage of the plant, as sorghum plant age greatly influences SCA colonization through differences in triterpenoids and available sugars.
