From the beginning of 2000 the development of a phylloxera leaf form was fixed on vineyards of the South of Ukraine at all growing grapes varieties, including European grafted varieties. The work purpose is studying of bioecological features of development of a phylloxera leaf form, the search of its natural enemies and selection of preparations for effective protection of grapes plantings. In the course of research we studied the influence of abiotic factors (air temperature, amount of precipitations, the sum of active temperatures) on development of a phylloxera leaf form; the efficiency insecticide�s action from various chemical groups; harmfulness of a phylloxera leaf form; biocenotic communications of a phylloxera leaf form of with the complex of entomophages. Field experiments were conducted according to "A technique of a field experiment". The spreading of a phylloxera leaf form of in the field conditions at various grapes varieties was studied by a method of route inspections. According to the results of three years' research the close correlation connections between the development of a phylloxera leaf form and the following abiotic factors were established: air temperature (r =-0,84), sum of active temperatures (r =-0,90), amount of precipitations (r = 0,99), hydrothermal coefficient (r = 0,95). On the basis of the obtained data the optimal terms of sprayings of grapes plants against a leaf form of phylloxera are established. By the results of tests of various systems of protective measures the calculation of economic efficiency of grapes production was carried out. It is established that the Karate Zeon is the most effective preparation against a leaf�s form of phylloxera. The predatory species of insects are revealed, it is possible to use them in a biological method of grapes plants protection.
