本研究以甘蔗品种(Saccharum Spec.)为研究对象。(Poaceae)，以甘蔗黄叶病毒(SCYLV)为载体的甘蔗麦长管蚜Melanaphim secchari(Zehntner)(半翅目：姬蜂科)。通过为期3年的田间试验和盆栽试管苗及离体叶的室内试验，对品种R365进行了抗性鉴定。R365通过杀菌和抗菌，减少了田间的蚜虫数量。利用电穿透图谱技术，我们检测到了R365韧皮部中滞留的蚜液和抑制被动的韧皮部汁液吸收。抗性因子也被证明对SCYLV的另一种媒介--玉米麦长管蚜(半翅目：蚜科)有效。
This study focuses on the resistance of sugarcane, Saccharum spec. (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 a 3-year field trial and laboratory experiments on potted plantlets and excised leaves. R 365 reduced aphid populations in the field by antixenosis and antibiosis. Using the electrical penetration graph technique, we detected delayed aphid salivation in phloem and inhibition of passive phloem sap uptake in R 365. The resistance factors also proved to be effective against the corn leaf aphid, Rhopalosiphum maidis (Fitch) (Hemiptera: Aphididae), another vector of SCYLV.
