A market price of 2017 the wheat crop (420 E.L/Aradab) and costs of control measures 90 E.L/feddan was standard, during flowering and heading stage. The calculated economic injury level (EIL) and economic threshold (ETL) in average were 7.03 and 2.26 aphid/ spike/ feddan, respectively. Calculated gain threshold was 0.21 Ardab/feddan.
