Severe forest conditions make it necessary to optimize the environment due to the protective plantations of different types and ecological categories. The use of woody plants unusual for a given area as part of multifunctional stands is one of the main methods for increasing the ecological capacity of the territory, changing the structure and population of insects. The study was conducted in Volgograd, Samara and Rostov regions. By the degree of biotic potential accumulation among the trees adapted in the arid region, plants of the Ulmaceae, Rosaceae and Fabaceae families are distinguished. The introduction of woody vegetation into new territories is also accompanied by the penetration of alien species of pests. Currently, among the phyllophages of woody plants used in landscaping various landscapes, there are invader insects. In urban areas, these species are particularly closely associated with Robinia pseudoacacia L. The most numerous as part of the pests of assimilation apparatus of this plant are Obolodiplosis robiniae (Haldeman, 1847) and Nematus tibialis (Neuman, 1837). Dissemination of Robinia by these insects in the protective forest plantations varies greatly. In the roadside forest plantations and the agroforest plantations in the composition of dendroflora the species of the family Ulmaceae are predominant. Among the invasive species that appeared in them is Aproceros leucopoda (Takeuchi, 1939); in these stands, it almost completely destroys the elm foliage. In the crowns of trees of recreational landscaping, single individuals of this species are found. Among the dendrophages of the stands of urbanized and forest-agrarian landscapes, open-living leaf-eating insects giving outbreaks of mass reproduction (Xanthogaleruca luteola, Dicranura ulmi, Cladius ulmi, Aproceros leucopoda) stand out. Wide spread and increase in the number is observed in Obolodiplosis robiniae and Fenusa ulmi.","PeriodicalId":33303,"journal":{"name":"Sotsial''noekologicheskie tekhnologii","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69787506","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In total 71 lichens species including 25 species on the fruit and berry crops were found. On many trees, even in forests the variety of species of lichens is strongly depleted. This is especially true for rural settlements, razing places, keeping and running cattle. Bryoria and Usnea species at the rural settlements and their surrounding area were not found. It was shown that G. scripta is a pioneer species on the speckled alder under the conditions of relatively strong shading and humidity.","PeriodicalId":33303,"journal":{"name":"Sotsial''noekologicheskie tekhnologii","volume":"139 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69787667","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
