ABSTRACT
The sunn pest Eurygaster integriceps is the most important insect of cereals in Iraq and other countries. In this study, the field efficacy
of 10 different kinds of insecticides with various mode of action was evaluated against sunn pest E. integriceps infested wheat on
field at middle of Iraq. Experiments were conducted in 11 wheat fields with
each field 0.5 ha, located in the middle
of Iraq (Wasit and Salahudain governorates) during season 2015-2016.
The wheat fields contained common varieties of wheat planted 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 insecticide used showed high efficacy (80.1%-93.8%) in reducing
number of E. integriceps adults after one week of treatment, reaching
0.2-0.8 insects/m2 compared to 3.6 insects/m2 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.
