Aphids belong to the important group of pests on winter wheat in Vojvodina (Serbia). The species Sitobion avenae seems to be more harmful than other species. Every year, aphids appear in cereal crops, but in varying intensity. That depends on climatic conditions and on the activity of natural enemies during the growing period. Cereal aphids serve as food for a wide spectrum of aphid-specific, as well as polyphagous predators. During the period of investigations (May 4 - July 5, 2008), in the vinicity of Novi Sad, within colonies of aphids on winter wheat crops, many species of specific and generalist predators have been recorded. These findings indicate that winter wheat crops maybe regarded as an ecological reservoir for natural enemies of aphids.
