Dovgan S. The Agroecological ground of prognosis of reproduction of main of harmful specieses of insects in the different ground-climatic areas of Ukraine.

Dissertation on the receipt of scientific degree of doctor of agricultural sciences after specialty 16.00.10 - is an entomologist. National University of Life and Environmental Sciences of Ukraine, Kyiv, 2010. In 1968-2007 supervisions certain to the basic predictors for prognosis of reproduction of basic harmful specieses of insects in all soil- climatic areas of Ukraine, which by authenticity over 70% allow to expect the seasonal and long-term amount of insects on the concrete sowing and planting of cultural plants. It is set that by leanings factors which influence there are a temperature of air and intensity of sun on forming of entomokompleksis. These indexes with the high coefficient of correlation stipulate a survival, both monofagiv and polifagiv in all basis areas of investigation. The long-term dynamics of quantity of entomokompleksis and selected periods of getting up and decline of quantity of wreckers is first appraised, both on species and on population levels. As a result of long-term researches the mathematical models of prognosis of quantity of wreckers which allow to optimize protective measures in all soil- climatic areas of Ukraine are made. New indexes are first developed in relation to the timely prognosis of reproduction of insects in sowing of the field and vegetable cultures, and also planting of apple-tree. Cross-correlation dependences are described by an author, and also the mathematical models of modern prognosis of quantity of insects are made it is necessary to inculcate in all areas, districts and farming's of Ukraine. New method of the modern monitoring of wreckers offered to the production of receptions, and also resource-keep technologies is the criterion of optimization of economic, ecological and economic mechanism of control of methods, protection of plants on the all stages of forming of high and high-quality harvest of agricultural cultures.
