SUMMARY An attempt was made in 1968 to reduce a wheat bulb fly population in a field in northern England by means of insecticidal seed dressings on early and late‐sown winter wheat. Ethion seed dressing reduced plant and shoot attack and also decreased the number of larvae within the plants on the late‐sown plots but not on the early‐sown. Chlorfenvin‐ phos seed dressing had no significant effect on either sowing. It is concluded that the control of wheat bulb fly populations by the use of these seed dressings on wheat crops in the previous year is not a promising means of control.
