Aphidoidea in the order Hemiptera. It is a true bug and sucks sap from plants.[1] It is considered a major pest in cereal crops, especially in temperate regions, as well as other hosts in parts of Northern Europe.[2][3] It is the principal vector of many viruses in economically important field crops.[2]

Host plants and distribution

R. padi has a worldwide distribution and according to research, they can colonize a number of dicotyledon host plants, although their preference is within

Gramineae plant species. It is also commonly found in maize
growing regions.

Virus vector

Bird cherry-oat aphid can vector a number of serious diseases including the

barley yellow dwarf virus (BYDV), the cereal yellow dwarf virus–RPV, filaree red leaf virus, maize leaf fleck virus, and rice giallume virus. It is also known to cause oat yellow leaf disease and the onion yellow dwarf virus.[2]
