Abstract
The purpose of the study was to study features seasonal fluctuations in aggregate dynamics density interspecific biodiversity of natural populations of beneficial insects, pests and entomophages host of cereal aphids throughout the growing season of winter wheat in the steppes of Ukraine. Comparative, analytical, field, statistical and mathematical. The results of observations of the dynamics of aggregate density of harmful insect herbivores cereal aphids and their beneficial insect afidofahiv on winter wheat crops. Determined that the highest density of pests in crops of winter wheat was 19 - 110 copies. / 100 bursts of larvae and their entomophagous coccinellide was in the range of 10 to 105 specimens. / 100 bangs сonclusions. Based on our own research suggested making timely monitoring of harmful insect herbivores cereal aphids and their beneficial insect afidofahiv to establish and need chemical protection of winter wheat crops from herbivores. Proposals to make timely route inspection records pest density in two winter wheat growing season: spring, summer and autumn.
