Project number RD-2011-3758

AHDB funding £62,857

The problem

Wheat bulb fly is a major pest of wheat in England and Scotland but numbers fluctuate considerably from year to year. Incidence generally increases following a wet harvest period, such as in 2004 when 50% of fields had egg populations above 250/m². Between 1984 and 2010, the probability of fields having an above threshold count has ranged from 3 to 50%.

Project aims 

To establish the annual incidence of wheat bulb fly in the autumn to allow farmers/agronomists to decide on the need for insecticidal seed treatment.

Approach 

To measure the incidence of wheat bulb fly each autumn in the infested areas and to forecast the need for seed treatment.

Benefits to the industry 

The project will indicate the need for seed treatment against wheat bulb fly.  Information on pest egg numbers is a vital component of risk assessment and will help to promote a rational approach to insecticide use against this pest.
