“…Bulygin introduced the concept of bioclimatic cyclicality into scientific terminology. Subsequently, using the example of two 30 years, the cyclic climate variability due to the cyclic activity of the Sun and the effect of these changes on the frost resistance and reproductive capacity of introduced species were shown [1][2][3]. As a result of temperature rise, natural zoning changes, affecting ecosystems [4][5].…”

The created collections of woody plants made it possible to evaluate the life cycle of forsythia Forsythia ovata Nakai, privet Ligustrum vulgare L., and high ash Fraxinus excelsior L. of the Oleaceae Hoff family. et Link. and their response to changing climatic conditions. Tall ash, common privet froze every year to the level of snow cover. The flower buds of the forsythia froze, and it did not bloom. Due to the increase in the average annual temperature from 1.7 °C to 2.69 °C since 1990, forsythia and privet began to bloom and bear fruit. Introductory populations were created and the most frost-resistant and abundantly flowering individuals were selected. But as a result of abnormal weather conditions and climate cyclicality, all young and old privet plants died in 1998. Common privet plants began to bloom profusely only in 2021 (sowing in 2018). High ash plants fully recovered and reached a height of 10-12 m.

This article discusses the possibility of using the entomopathogenic fungus Lecanicillium muscarium R. Zare & W. Gams (Ascomycota: Hypocreales) against the fir adelgid Adelges pectinatae pectinatae (Cholodkovsky, 1888) and Siberian cedar adelgid Pineus cembrae (Cholodkovsky, 1888) on the Siberian fir Abies sibirica Ledeb., and pines Pinus sibirica Du Tour and Pinus banksiana Lamb. The blastospores of the entomopathogenic fungus L. muscarium strain G-033 VIZR, in the concentration of 5x107 spores/ml, showed a high efficiency on both of the species of adelgid. On the 17th day, the mortality of P. cembrae was 73% on P. sibirica and 61% on P. banksiana, and the mortality of the species A. pectinatae pectinatae on A. sibirica was 74%. The effect of the spore application had a prolonged effect over the next month on all treated trees. Keywords: entomopathogenic fungi, Lecanicillium muscarium, adelgid, conifers
