Wheat Grain Damage by Eurygaster integriceps Puton (Hemiptera, Scutelleridae): Diagnostics and Detection Methods

The sunn pest Eurygaster integriceps Put. is one of the most economically important insect pests of grain crops in many countries all over the world. This paper presents an analytical review of the world literature devoted to the harmful activity of the sunn pest and its biological background, in particular, variation in grain damage by the pest and methods of its assessment. All the currently known methods of detecting grain damage by the sunn pest (including visual assessment, radiography, infrared microscopy, and the express scanning method) have certain disadvantages and require improvement. Infrared microscopy and computer scanning methods provide the highest accuracy combined with the greatest ease of use in identifying damage caused by the sunn pest.
