Metopolophium dirhodum, the rose-grain aphid or rose-grass aphid, is a species of sap-sucking insect in the family Aphididae found worldwide. [1] Its primary host is rose, and its secondary host is a grass, including cereals such as wheat, barley, oats and rye. It is an important vector of the barley yellow dwarf virus (BYDV) which causes serious reductions in yields of affected crops.


The rose-grass aphid has an almost cosmopolitan distribution, being found in most parts of the world where its secondary hosts are grown. It was first detected in New Zealand in 1982. [2]
