Entomological Review

Ecological inefficiency of conventional IPM programs for apple orchard protection in the North Caucasus results from arbitrary use of compounds producing opposite ecological effects, i.e., broad-spectrum chemical insecticides after environment-friendly selective ones, which destroys the apple orchard agroecosystem. The investigation was aimed at developing an effective and ecologically acceptable program with alternation of environment-friendly compounds which act along the same vector to preserve the populations of natural enemies of the pests and thus to stabilize the apple orchard agroecosystem, i.e., create an ecological type of orchard. In this kind of orchards, broad-spectrum chemical pesticides are prohibited whereas selective biological compounds (including synthetic ones) and methods are welcomed. The test runs of the resulting pest and enemy management (PEM) programs based both on bioregulators (Insegar, Match, Dimilin) and bio-insecticides (Phytoverm™, Lepidocid™, etc.) in 2007 and 2009 demonstrated their high efficiency: the apple fruit damage by codling moth was 1.2% and 0.3%, respectively. The test of sticky bands fixed on apple tree trunks to prevent ants from getting to the crowns showed a significant increase in the abundance of predaceous bugs which sharply reduced the green apple aphid population. © 2010 Pleiades Publishing, Ltd.

Effect of molasses, a waste formed in manufacture of sugar, on the gypsum setting time was studied. It is shown that molasses solutions can be used to control the hardening time of the gypsum paste. © 2013 Pleiades Publishing, Ltd. Source

Triaxial tests are often used, along with other research methods, in order to define parameters of geotechnical data. The main topic being conferred in work is analysis of influence, exerted by stamp and latex shell, upon the results of triaxial machine soil tasting. The stabilometer modeling and verification was produced. Calibration of soil model parameters, derived from triaxial tests, is brought in work. The necessity of three dimensional simulation of soil testing process is pointed out in order to take into account stamp and shell influence. © 2011, International Journal of GEOMATE. Source
