Abstract：[Objectives] To determine the best monitoring and pesticide application methods for Sitodiplosis mosellana and thereby provide a basis for the effective control of this pest. [Methods] Soil elutriation and yellow sticky traps were used to analyze the relationship between the number of wheat midges and wheat infestation rate, as well as the number of larvae on each ear. Chlorpyrifos and Imidacloprid were applied in two different ways；by spraying and by poisoning the soil, and their relative effectiveness were compared. [Results] There was a significant relationship between the number of adult S. mosellana caught in yellow sticky traps and wheat infestation rate, as well as the number of larvae on each ear. Spraying Chlorpyrifos at the wheat heading stage was the most effective control method, reducing the infestation rate by 79.55% compared with the control. [Conclusion] Yellow sticky traps are more suitable for predicting damage to wheat crops by S. mosellana than the soil elutriation method, and spraying Chlorpyrifos at the heading stage is the best way of controlling S. mosellana on wheat crops.
