Vestnik OrelGAU, 4(49), August 2014 UDC 633.12 BUCKWHEAT IN THE CONSERVATION OF INSECTS SPECIES DIVERSITY Naumkin V.P., Lysenko N.N., Doctors of Agricultural Sciences Orel State Agrarian University, Orel City, Russia E-mail: lysenko_nik@mail.ru ABSTRACT Buckwheat - one of the most important of the field rotation crop, attracting and keeping a large number of insects. <...> Entomocenosis of a buckwheat field consists of more than 170 species of insects pollinators, phytophags, entomophags. <...> They feed on nectar, pick up it and make pollination possible. <...> Bee honey, wild bees, bumblebees, wasps, other hymenopterans, dipterous, beetles are widely spread. <...> The third group of insects, whose imagos feed on flowers and larvae (and sometimes imago) hymnical or parasitize on phytophags of buckwheat and on other crop rotation fields or on neighboring natural biotic communities: Coccinellidae, Chrisopidae, Syrphidae, Tachinidae, Phasiae, parasitic hymeonopterans. <...> These insects need not only buckwheat plants, but also its phytophags that are food for their larvae. <...> The fifth group of insects is real predators - includes Carabidae and Staphylinidae mainly. <...> The sixth group is insects, occasional visitors of buckwheat agrobiocenosis. <...> Relations between insects, living in the buckwheat field, with other biocenosis components, are generally trophic (direct and indirect): «plants - insects phytophags»; «plants - insects phytophags - entomophags», «insects «neutrals» - entomophags»; and phoryc (zoochory): plants - insects pollinators. <...> Topical communications appear under the influence of the plant defining living conditions of phytophags and entomophags (buckwheat crops as a habitat of insects with granting possibility of a shelter, a meeting of genders, reproduction and habitation of different stages of evolution). <...> KEY WORDS Buckwheat sowing; Entomocenosis; Agrocenosis; Insects pollinators; Phytophags; Entomophags; Trophyc relations; Phoryc relations. <...> Buckwheat agrocenosis differs from others field agrocenosis that, besides the biological features of crop, chemical means of protection from undesirables practically aren't used during cultivation technology. <...> On the other hand, being entomophillous buckwheat attracts a large number of insects feeding on nectar and pollen of flowers. <...> The study of insects of buckwheat agrocenosis is important, helps to determine species diversity, number dynamics, the dominance of species and their <...>
