Sunn pest, a name that refers to a complex of Hemipteran bugs, of which the dominant species is Eurygaster integriceps. The adult, which is mm long, is grayish-yellow to black. Such color polymorphism may be due to genetic variability or in response to environmental conditions.
The male has ten spiraclesits last abdominal segment is larger than in that of the female, which has 12 spiracles and is larger than the male.
Eurygaster integriceps occurs throughout the Mediterranean basin, in North Africa, and the northern regions of the Middle East, which include Turkey, Syria, Lebanon and Jordan. Wheat, barley and other cultivated or wild species of graminaceous plants.
The adult bug euryygaster seasonable adult diapause in the winter after migrating to mountain sites.
Diapause terminates in the spring and the pest returns to areas with cereal crops, where field populations gradually increase due to continued invasions.
Females oviposit in clusters of eggs, mostly on the undersides of smooth leaves. The sex ratio may vary between different cohorts, depending on environmental conditions during embryonic development.
High temperatures and humidities promote pest outbreaks whereas harsh winters adversely affect eutygaster in diapause, decreasing the extent of pest outbreaks. The Sunn pest is a serious pest of graminaceous crops like wheat and barley.

An entire crop may be destroyed in the absence of control measures. In addition, the baking quality of the flour can be adversely affected by the degradation of the wheat.
In the Middle East the sunn pest complex is composed of other bugs that accompany E. Their numbers vary from year to year, a significant attack occurring about once itegriceps seven years, causing yield losses worth tens of millions of dollars.
The early application of fertilizers on winter crops, the early sowing of spring crops, and the autumnal ploughing of crop residues.
Varieties with a strong gluten index have some tolerance to the pest. IGRs prevent the emergence of adults and decreases their damage. However, pest populations frequently remain low enough so that spraying is unnecessary. Several generalist spiders and predatory beetles prey on the pest.
A tachinid fly attackes the late instar nymphs and adults, castrating them. In some parts of Turkey hymenopterous egg parasitoids of the genus Trissolcus effectively control the pest. Entomopathogenic nematodes and various isolates of entompathogenic fungi also infect and kill the pests.
