Flea beetles: These tiny beetles feed on the leaves and stems of young wheat plants, causing them to become stunted or even die.
Wheat stem sawfly: The larvae of this insect burrow into the stems of wheat plants, weakening them and making them more susceptible to lodging (falling over).
Hessian fly: The larvae of this fly feed on the stems of wheat plants, causing them to become stunted and produce smaller heads of grain.
Wheat midge: The larvae of this fly feed on the developing seeds inside the wheat heads, reducing the yield and quality of the grain.
Aphids: These small, soft-bodied insects suck sap from the leaves and stems of wheat plants, causing them to become weakened and stunted.
Grasshoppers: These insects can feed on the leaves and stems of wheat plants, causing significant damage, especially during outbreaks.
Armyworms: The larvae of these moths can feed on the leaves and stems of wheat plants, causing extensive defoliation.
Wireworms: These are the larvae of click beetles, and they feed on the roots of wheat plants, causing them to become stunted or die.
Root maggots: These are the larvae of flies, and they feed on the roots of wheat plants, causing them to become damaged and less productive.
Other insects: There are many other insects that can damage wheat, including weevils, leafhoppers, and mites.
It is important to note that the specific insects that are a problem in a particular area will vary depending on the climate, the type of wheat being grown, and other factors. Farmers typically use a combination of methods to manage insect pests, including crop rotation, insecticide applications, and biological control.
