This week’s Insect of the Week is the group of aphids known as cereal aphids. These aphids include the corn leaf aphid, the English grain aphid, the oat-birdcherry aphid and the Russian wheat aphid. They feed on cereal crops and are vectors of viruses, causing lower crop quality and yield. There are several natural enemies of cereal aphids, including various species of wasps and beetles.
For more information on cereal aphids, see our Insect of the Week page.
