Slobodenyuk O. The western flower thrips Frankliniella occidentalis Pergande (Thysanoptera: Thripidae) as the structural element of closed ecological systems in Ukraine.

The object of the work is the ecological-faunistic complex of thrips as a structural element of closed soil ecosystems in Ukraine. The aim of the work is to detect the sinecological peculiarities of thrips complexes of closed ecosystems in Ukraine; ecological-biological peculiarities of a dominant thrips species - Frankliniella occidentalis Pergande (Thysanoptera: Thripidae) as a structural element of these ecosystems. The methods used for the research are field researches, entomological monitoring; virologic, analysis of variance by computer programs Statistica 99 Edition and " Species diversity and richness" of companies Pisces Conservation Ltd. The species and space structure, the density of thrips populations in Ukraine in phythocenosis of vegetables and ornamental plants of closed ecosystems are studied in the work for the first time in Ukraine. It was defined that all thrips species belong to plant-eaters and are characterized by trophic confinement. Some ecological and biological propertiesof Tospovirus and ecological peculiarities of its transmission were studied. It was theoretically justified and experimentally proved that pest and diseases control integrated system, based on the ecological and biological quantity control, is an important anthropogenic factor. This factor influences on the formation of the ecological system of closed soil. The sphere of use is the greenhouse farm.
