Vergeles P. Ecological substantiation of the protection of blackberry from the scale-winged pests in the Central Forest-steppe of Ukraine.

Objects of research - are harmful activity of complex of scale-winged фитофагов in planting of blackberry. The purpose - development of the original environmentally sound system of defence of blackberry from the complex of the scale-winged wreckers with the primary use biological and other unchemical receptions for a receipt highly and stable harvest of berries, suitable for the use for any necessities. Methods - generally accepted in entomology and defence of plants : the field and laboratory, statistical method. Scientific novelty - specific composition of scale-winged фитофагов is specified in agrocenosis of blackberry of Central Forest-steppe of Ukraine. Ekology-ekonomic descriptions of the scale-winged wreckers are investigational currants ontogenesis of which is related to soil. It is set that in the agroekological terms of Central Forest-steppe there is one and two year cycle of development of Synanthedon tipuliformis Cl., of currants. Primary majority of population completes ontogenesis for one year At damaged Synanthedon tipuliformis Cl., of 12% escapes, the losses of harvest of currants arrive at 42,5%. The agrotechnical method of defence of currants is worked out by black from Zophodia grossulariella Zink. through mulching of soil a layer to peat, technical efficiency - 93,2%. First optimal norms, lines and multipleness of settling apart of Trichogramma pintoi Voeg., are ecologically reasonable for control of quantity of the scale-winged wreckers. Technical efficiency of Trichogramma pintoi Voeg., at the double settling apart in a norm 100 females on a bush at the beginning and at mass eggs, in adjusting of Exapate congelatella Cl. - 46,2%, Archips rozanna L. - 52,3%, and Pandemis ribeana Hb., - 54,8%. Branch - agriculture, protection of plants.
