Resistance to Melanaphis sacchari in the sugarcane cutivar R 365 as assessed using electrical penetration graph technique

This study focuses on the resistance of sugarcane, Saccharum sp. (Poaceae), to the sugarcane aphid, Melanaphis sacchari (Zehntner) (Hemiptera: Aphididae), which vectors Sugarcane yellow leaf virus (SCYLV). Resistance was characterized in cultivar R 365, using the electrical penetration graph technique on aphids feeding on potted plantlets. We detected a delayed aphid salivation in phloem and inhibition of passive phloem sap uptake in R 365.
