What is frit-fly?

As an AI language model, I do not have personal opinions or experiences. However, I can provide information about Frit-fly that could be useful.

Frit-fly (Oscinella frit) is a type of fly that belongs to the family of insect pests. It is a small fly with a length of about 2-3mm and is commonly found in the UK, Europe, and North America. The female Frit-fly lays eggs on or near the stem of plants, and the larvae then burrow into the stem and feed on the plant sap. This can lead to stunted growth and wilting of the affected plants. The adult Frit-fly feeds on flower nectar and other plant fluids. They are most active during the months of May and June.

Frit-flies are known to affect crops such as cereals, sugar beet, and beans. They can cause significant economic losses to farmers as they can destroy large areas of crops and reduce yield. Control measures for Frit-flies may include chemical pesticides, crop rotation, and insect-resistant varieties of crops. Early detection and proper management can help prevent significant damage to crops.
