Special Feature


Aphids can be problematic pests in wheat. There are several species of aphids in wheat fields. These include the English grain aphid and the bird-cherry oat aphid. Different species have different life cycles. Aphids do little direct damage to wheat plants but can be problematic due to transmission of viruses.
