ABSTRACT. Long-term data are provided on the influence of two spring wheat cultivation practices (traditional and no-till when the soil is untreated) on harmful and useful entomofauna. In general, the technology of cultivation practice adopted for the second crop rotation had no effect on the number of cereal aphids. In the third crop rotation the number of aphids on wheat with no-till was 1.4-1.6 times higher than for the traditional method. The complex level of chemical treatment without insecticide had an insignificant effect on the abundance of cereal aphids and predatory bugs. The variety of wheat under traditional cultivation did not affect the number of cereal aphids, but for wheat cultivated by no-till the average number of cereal aphids was 1.3-1.7 times higher for the variety Novosibirskaya 31 than for Novosibirsk 44. The number of nabid bugs did not depend on the wheat variety, but the number of orius bugs was 1.7-2.0 times higher for the variety Novosibirskaya 44. The duration of cultivation by No-Till technology influences the abundance of cereal aphids on the wheat.
