Abstract
作物在成長過程中經常受到植物病毒的侵害，在眾多的植物病毒中，約有 76% 的病毒種類藉由病媒生物所傳播。昆蟲為重要的植物病毒媒介生物，其中蚜蟲更是具有舉足輕重的角色。蚜蟲大多以非持續性傳播模式(nonpersistent transmission mode) 來媒介傳播植物病毒。蚜蟲之寄主植物選擇與取食行為是蚜蟲媒介植物病毒流行病的重要因子，其寄主範圍 (host range) 及生活史為決定植物病毒傳播率的關鍵。從傳播生物學的層面來看，要防治蚜蟲所傳播的病毒病，應從病媒－病毒－寄主植物三方面的交互關係著手。必須包含消除田間感染源以及減少或避開病媒蚜蟲族群兩大策略，如此才可以有效控制蚜蟲媒介病毒病害的流行。本文將介紹傳播植物病毒的蚜蟲之種類與生物特性，探討蚜蟲如何傳播植物病毒，最後提出病媒蚜蟲與蚜媒病毒病的防治策略。
Plant viruses often infest agricultural crops during the growth season. Among plant
viruses, there are about 76% of virus species transmitted by various vectors. Insects are the important vectors of plant viruses, and among them aphids play an important role in virus transmission. Most aphids transmit plant viruses in a nonpersistent transmission mode. Host plant selection and feeding behavior of aphids are important factors affecting the epidemics of plant viral diseases. Also, host range and life history of aphids are keys to determine the transmission rate of plant virus. From the perspective of transmission biology, it is crucial to consider vector-virus-host plant interactions in order to control the aphid-borne viral diseases. Two control strategies are suggested to effectively control epidemics of aphid-borne viral diseases: (1) to eliminate the source of pathogens in the field and (2) to reduce or avoid the population of vector aphids. This paper describes species and biological characteristics of plant virus-transmitting aphids and its transmission mechanism. Finally, we suggest control strategies of aphid vectors and aphid-borne viral diseases.
