MATHEMATICAL MODELING OF POPULATIONS CEREAL APHIDS, AND ITS ENTOMOPHAGES (PARASITES AND PREDATORS) AT DIFFERENT STAGES OF ONTOGENESIS WINTER WHEAT AND WEATHER AND CLIMATE FACTORS

Glazunova N.N, Bezgina Y.A, Ustimov D.V
Applied statistical methods (regression and correlation analyzes) using basic computer programs «Statistics-6» for the processing of experimental data linking population numbers of cereal aphids lady beetles, flower flies, hrizopid, afidiid, with climatic conditions in different phases of development of winter wheat (booting, earing, flowering, milk ripeness, waxy ripeness and full ripeness) depending on temperature and precipitation in the area of the Central Caucasus. The quantitative relationship between the size of populations of insects and parasites in the form of plots and empirical equations of the first, second and third orders in different phases of development of winter wheat during the period from 1998-2005. Shows the combined effect of climatic factors on the development of insect populations in the form of surface equations linking populations with temperature and amount of precipitation in different periods of ontogenesis of winter wheat. According to the results of mathematical modeling of the proposed changes population of cereal aphids and its entomophages ( parasites and predators ) at different stages of ontogenesis of winter wheat and climatic factors in the form of empirical equations of first and second order for the region studies.
