Banana plants are affected by various viral diseases, among which the most devastating is the "bunchy top", caused by the Banana bunchy top virus (BBTV) and transmitted by the aphid Pentalonia nigronervosa Coquerel. The effect of BBTV on attraction mechanisms of dessert and plantain banana plants on the vector remains far from elucidated. For that, attractiveness tests were carried out using a two columns olfactometer for apterous aphids, and a flight cage experiment for alate aphids. Volatile Organic Compounds (VOCs) emitted by either healthy or BBTV-infected banana plants were identified using a dynamic extraction system and gas-chromatography mass-spectrometry (GC–MS) analysis. Behavioral results revealed a stronger attraction of aphids towards infected banana plants (independently from the variety), and towards the plantain variety (independently from the infection status). GC–MS results revealed that infected banana plants produced VOCs of the same mixture as healthy banana plants but in much higher quantities. In addition, VOCs produced by dessert and plantain banana plants were different in nature, and plantains produced higher quantities than dessert banana trees. This work opens interesting opportunities for biological control of P. nigronervosa, for example by luring away the aphid from banana plants through manipulation of olfactory cues.

香蕉植株受到各种病毒病的影响，其中最具破坏性的是“束顶”，由香蕉束顶病毒（BBTV）引起，由黑叶蚜虫Pentalonia nigronervosa传播科克雷尔。BBTV 对甜点和大蕉香蕉植物对载体的吸引机制的影响仍远未阐明。为此，使用两柱嗅觉计对无翅蚜虫进行了吸引力测试，对有翼蚜虫进行了飞行笼实验。使用动态提取系统和气相色谱质谱 (GC-MS) 分析鉴定健康或受 BBTV 感染的香蕉植物排放的挥发性有机化合物 (VOC)。行为结果显示蚜虫对受感染的香蕉植物（独立于品种）和大蕉品种（独立于感染状态）具有更强的吸引力。GC-MS 结果显示，受感染的香蕉植物产生的 VOC 与健康的香蕉植物产生的混合物相同，但数量要高得多。此外，甜食和芭蕉树产生的 VOCs 在性质上是不同的，大蕉比甜食香蕉树产生的量更高。这项工作为生物控制提供了有趣的机会P. nigronervosa，例如通过操纵嗅觉线索从香蕉植物中引诱蚜虫。
