中文摘要：病原菌侵染植物时，可能会引起寄主植物与昆虫、昆虫与其天敌间的交互作用。病原菌白叶枯病菌可引起水稻的维管束疾病，本文研究了白叶枯病菌的侵染对水稻及随后引起的褐飞虱（BPH）与其主要天敌黑肩绿盲蝽间交互作用的影响。研究结果显示，水稻对褐飞虱的抗性仅在白叶枯病菌侵染3天后有所增强，但白叶枯病菌的侵染并没有影响褐飞虱的发育和繁殖力。褐飞虱对白叶枯病菌侵染的水稻植株表现出更高的选择偏好，然而褐飞虱取食后，黑肩绿盲蝽更偏好于选择白叶枯病菌侵染的水稻植株，但若没有褐飞虱取食，则黑肩绿盲蝽会更偏好选择健康的水稻植株。本研究结果表明，白叶枯病菌的侵染可显著影响水稻植株与两种非介体昆虫褐飞虱及其天敌之间的交互作用，尽管这些影响是在侵染后以时间变化的模式表现出来的。
外文摘要：Pathogenic infection on plants may affect interactions of host-plants with their herbivores, as well as the herbivores with their predators. In this study, the effects of infection by pathogenic bacterium Xanthomonas oryzae pv. oryzae (Xoo), which causes a vascular disease in rice, on rice plants and consequent interactions with a rice herbivore, brown rice planthopper (BPH) Nilaparvata lugens, and its major predator, Cyrtorhinus lividipennis, were investigated. The results showed that the rice plants exhibited increased resistance to BPH only at 3 d post-inoculation of Xoo, while the Xoo infection did not affect the development and fecundity of BPH. BPH exhibited a higher preference to Xoo infected rice plants, whereas C. lividipennis preferred the Xoo infected rice plants after BPH fed, but preferred healthy rice plants without BPH fed. Volatile organic compounds emitted from Xoo rice were significantly higher than those from healthy rice plants, Xoo infection on BPH fed plants caused rice plants to emit more the herbivore-induced plant volatiles, while all of these changes correlated to the temporal dimension. These results demonstrated that Xoo infection significantly influenced the interactions of rice plants with two non-vectors, BPH and its predator, although these effects exhibited in a temporal pattern after infection.
