A sunn pest is an insect belonging to a group representing several genera of the 'shield bug' (Scutelleridae) and 'stink bug' (Pentatomidae) Families, with the species Eurygaster integriceps being the most economically important. Sunn pests are found in parts of North Africa, throughout West Asia and many of the new independent states of Central Asia. The sunn pest is one of the most serious pests of wheat and barley in West Asia, where over $42 million (U.S.) is spent for its control. Yield loss from its damage has been estimated at 20-30% in barley and 50-90% in wheat. This insect damages these crops by feeding on leaves, stems and grains. During feeding they also inject chemicals that greatly reduce the baking quality of flour made from damaged wheat. If 2-3% of the grain is damaged, entire lots may be ruined because the flour will be unpalatable and the bread will not rise. Heavy attack causes wheat stems to break before harvest. Large areas of wheat sometimes remain unharvested because sunn pest damage is so severe. These insects also attack barley, though damage is usually low. Large outbreaks of sunn pests generally occur every 6 to 8 years and can potentially cause yield losses of tens of millions of dollars. Sunn pest management Currently, there is not a pest management strategy to control the sunn pest on a national or global scale. However, there are a number of methods that farmers can utilize to help limit the damage caused by these insects. Monitor pest populations; sunn pest populations vary from year to year in response to climatic conditions. Pest populations should be monitored annually to determine if it is necessary to spray for the insect. Keeping records of population levels is beneficial. Plant early-maturing wheat varieties and harvest early; damage is less if wheat is harvested before sunn pest reach adulthood. Growing early-maturing varieties and establishing a regional uniform planting date minimizes damage. Early harvesting methods must be developed in relation to local production methods and weather conditions. Maintain shelter belts around wheat fields. Natural enemies reduce sunn pest populations and should be encouraged. Cereal crops should not be grown on marginal lands in the foothills. These areas should remain as uncultivated habitats where flowers and grow undisturbed, providing shelter and alternative food sources, which improve survival of these beneficial insects. Use chemical insecticides only if needed. Selective insecticides should only
