The article describes a noctuid moth Cosmia affinis as a pest of deciduous trees. The main purpose of the work is to determine the percentage of damaged deciduous trees of different types, which were damaged by the pest noctuid moth and the influence of climatic factors on their numbers. The main work results are the following: calculated percentage of the trees leaf blades damage, the researcher has indicated the percentage of deciduous trees, damaged by noctuid moth, presented a phenocalendar of a noctuid moth Cosmia affinis development and the occurrence of pests’ frequency in number.

The article presents the main provisions of obtaining stable water-dispersion coloring systems for coniferous wood. The paint technology uses polymer dispersions, which differ not only in the nature of the film-forming agent, but also in stabilization systems, lyophilicity, film-forming ability. For the choice of film-forming substance, for the painting of coniferous wood, it is necessary to take into account the main technical characteristics of polymer dispersions and their properties. The main directions of development of the LCP technology are the improvement of decorative and operational properties of coatings through the development of new materials and methods of their application, reducing the use of harmful substances.

The authors of this article note that the fast pace and modern construction make qualitatively new demands on building materials and structures. While great attention is paid to the production of glued wooden structures. Such designs on a number of technical and economic indicators are superior to metal and concrete have low component weight, relatively high strength and stiffness with sufficient reliability and durability. At the same time, negative characteristics of the wood (the dependence of the properties from its structure, defects, need for and considerable expense of quality timber, excessive massiveness of the cross-sections, creep under sustained loading, etc.) restrict the scope and impair the indicators of glued wooden structures. One of the ways to address these shortcomings and increase techno-economic efficiency – reinforcement of sections of glued wooden structures and elements of steel or fiberglass reinforcement. This can significantly reduce the consumption of wood, reduce Assembly mass, to improve the quality and reliability of wooden structures, working mainly in bending and compression with bending.

Accumulated vast teaching and research material confirms the need for revival and application possibilities of folk decorative-applied art as an effective means of artistic and aesthetic development of personality in educational work with students. The important role of the educational impact of the national decorative-applied art is devoted to wooden architecture of the Tyumen region and the Tyumen city in particular. In the carved decor of Tyumen buildings traditions of Russian decorative art, folk motifs are widely used. Introduction in future students-teachers education of wooden architecture of the Tyumen region will have a definite aesthetic impact on the opinion of the authors. The practical application of this knowledge will be found on arts and crafts classes. Comprehension of compositional ornament construction or pattern of wooden architecture may appear in the production of their creative works.

The article describes a chinch bug Kleidocerys resedae (Panzer, 1797) as a pest of deciduous trees. The main purpose of the work is to determine the percentage of damaged deciduous trees of different types, which were damaged by the pest bug and the influence of climatic factors on their numbers. The main work results are the following: calculated percentage of the trees leaf blades damage, the researcher has indicated the percentage of deciduous trees, damaged by bugs, presented a phenocalendar of a chinch bug development and the occurrence of pests’ frequency in number. The author concluded that the main limiting factor, affecting the increase in the number of bugs is a high moisture level in Almaty.
