In our article, we outlined the bioecological features, distribution and degree of harmfulness of Zabrus tenebrioides Goeze. Bread beetle is one of the most dangerous pests of ear crops in the North Caucasus region, causing significant damage to winter ear crops on a larger area of the arable wedge. The beetle is 12-18 mm long, 5.3–8 mm wide, oblong-oval, convex monophonic black, less often dark brown with a metallic sheen, antennae and legs are brown. Egg 2.0–2.3 mm, rounded, white. Larva up to 25 mm, campodiform; white or grayish in color with large chitinized, brown spots on top and small segments on the sides; the last segment ends with two processes (urogomphs). Factors contributing to the development of bread beetle: noncompliance with the technology of cultivation of culture; favorable climatic conditions.
