[R] - Plants cultivated for their grains, from which flour is made. These consist primarily of straw cereals, belonging to the family of Gramineae: rye, oats, wheat, barley and triticale as well as rice, sorghum and millet. In Europe, another so-called cereal is also cultivated, belonging to the Chenopodiaceae family: buckwheat or sarrazin.
- Straw cereal pests: the most serious are aphids which are often virus vectors; most often involved are the bird-cherry aphid (Rhopalosiphum padi ), the grain aphid (Sitobion avenae) and the rose-grain aphid (Metopolophium dirhodum).
The starling (Sturnus vulgaris) and the rook (Corvus frugigelus) attack the seeds.
The field slug (Deroceras reticulatum), the marsh crane fly (Tipula paludosa) and the common vole (Microtus arvalis) eat the seedlings.
The wheat bulb fly (Delia coarctata) and frit fly (Oscinella frit) discolour the leaves.
Many species of nematode may cause damage: cereal cyst nematode (Heterodera avenae) and the ceral root-knot nematode (Meloidogyne naasi ).
The cereal leaf beetle (Oulema melanopa) and many species, including leaf miner flies (Agromyza spp.) attack the leaves.
The common wood mouse (Apodemus sylvaticus) cuts the stem under the spike. The house sparrow (Passer domesticus) eats the grain. The grain thrips (Limothrips cerealium) attacks the grain.
