Wheat bulb fly is found mainly in wheat and less so in rye and barley.
Scientific name: Hylemya coarctata
Other name: Delia
Greek name: Υλέμυια
In spring, the wheat bulb fly larva penetrates into the stem of the plant, causing the leaves to turn yellow, rot at the base and become easily detached. Early infestations usually result in the death of the plant. The damage resembles that of the Oscinella frit infestation.
The larvae are about 8 mm long, whitish in color, with no legs and lacking a cephalic capsule. Their anterior part is pointed and equipped with mouth hooks. On the abdomen they have 6 small projections.
Late sown crops are most at risk from this insect. Wheat bulb fly prefers fluffy brown soils.
