Sunn pests, the general term for a group of three dozen or more species of insect belonging to the sub-order Heteroptera, have been recognised as serious pests of wheat and other cereal crops throughout the Near and Middle East and much of the former USSR, for more than 70 years. This review is confined to one of the key species within this group, namely Eurygaster integriceps. Large outbreaks, which generally occur every 5-8 years, can cause yield losses of the order of tens of millions of dollars e.g. in northern Iraq in 1991/92 and 1994/95. As yet, no pest management strategy has been developed to control it economically or sustainably either on a national or global scale. Information on its taxonomy, biology, ecology, population dynamics (particularly the biotic and abiotic factors influencing or regulating population size and distribution) is reviewed in order to gain a better understanding as to how it can best be controlled. Much of this information is available only in 'grey' literature, in a language other than English--the lingua franca of most current scientific publications--or as unpublished reports. This review attempts to bring this information together and identifies constraints which appear to the author to be based on control strategies which rely mainly, if not solely, on the use of conventional broad spectrum insecticides.
