Karazhbey G. Biological features of main pests of sugar beet and seedling protection from them under conditions of the Nothern Steppe zone of Ukraine

The purpose of studies: The purpose of studies was to specify species composition of pests of sugar beet seedlings and their biological features in the Northern Steppe zone of Ukraine. Moreover, it is stipulated to carry out studies of the efficiency of action of new insecticides and their compositions against these pests, to establish the influence of plant toxication by formulations of the new generation on the initial growth and development of sugar beet plants. The object studies: pests of sugar beet seedlings and new insecticides. Methods of investigations. Laboratory, field and statistical ones. Established for the first time. Species composition of pests of sugar beet seedlings under conditions of the Northern Steppe zone of Ukraine is specified. It is established that the main phytophages of the crop are: Psalidium maxillosum F., Tanumecus palliatus F. Bothynoderes punctiventris Germ., Opatrum sabulosum L., Elateridae, Chaetonema. Trophic relations and harmfulness of Psalidium maxillosum F. arespecified. Spfera of application. The results obtained can be used in working out means of protection of sugar beet from their pests as well as in the process of training of students at biological and agricultural fac
