The Sunn pest Eurygaster integriceps is the most insect of cereals in Iraq and other countries. Field efficacies of ten different kinds of insecticides with various mode of action were evaluated against Sunn pest Eurygaster integriceps infested wheat on field at middle of Iraq. Experiments were conducted in eleventh wheat fields each measuring 1/2 ha located in the Middle of Iraq (Wasit and Salahudain governorates) at season 2015, contained common varieties of wheat planting in Iraq. The population density of the pest was at its highest level (start of April 2015) of mostly nymphs, adults and eggs. The results indicated that the recommended dose for each insecticides used showed high efficacy (80.1-93.8) in reducing numbers of E. integriceps adults after one week of treatment, reaching 0.2-0.8 insect per 1m2 compared to 3.6 per 1m2 in the control treatment. These results will assist the control program of this pest and in implementing pest management practices to reduce resistance development chances.
