The green peach aphid Myzus persicae is an economically important pest of wide range of crops worldwide. This insect does not only cause feeding damage but also transmits over a 100 different plant viruses. There is a need to develop new methods to protect crops from aphids and other agricultural insect pests.This project will study how aphid RNAs migrate within plants and modulate plant processes. Generating this fundamental knowledge will be important for assessing how these insects establish intimate interactions with plants and how they efficiently transmit viruses. The project is likely to lead to the identification of new strategies to control sap-feeding insect pests that do not damage beneficial invertebrates, such as bees.The project has the following three aims: (1) Annotate M. persicae RNAs that migrate systemically in plants; (2) Determine how aphid RNAs modulate aphid-plant interactions; and (3) Investigate mechanisms involved in systemic migration of aphid RNAs in plants.

绿色Myzus persicae是世界范围内危害多种农作物的重要经济害虫。这种昆虫不仅会造成进食损害，还会传播100多种不同的植物病毒。本计画将研究蚜虫核糖核酸如何在植物体内迁移及调控植物的生长过程。这些基本知识的产生对于评估这些昆虫如何与植物建立亲密的相互作用以及它们如何有效地传播病毒非常重要。该项目可能导致确定新的战略，以控制不损害有益的无脊椎动物，如蜜蜂的食树液昆虫害虫。研究蚜虫RNA在植物中系统迁移的机制;（2）确定蚜虫RNA如何调节蚜虫-植物相互作用;（3）研究蚜虫RNA在植物中系统迁移的机制。
