Analysis of phenological features pine sawfly and star sawfly-weaver in the conditions of Southern Urals. According to the research were compiled fenoklimogrammy development sawfly and star sawfly weaver under Southern Ural region depending on the prevailing meteorological situation. In conditions of extreme - continental climate of the Southern Urals features phenology of conifer-chewing phyllophages appear that fillofagi have a long diapause in several years associated with phyllophages adaptation to unfavorable climatic conditions. Do sawfly larvae stellate weaver marked diapause going sometimes 7 - 8 years that the forest-steppe and steppe zones contributes to the formation of chronic lesions in which high numbers of individuals stellate sawfly-weaver provides strong defoliation over several consecutive years.
