Офиостомовые грибы хвойных пород в Сибири

Abstract

Paper deals with current problems and perspectives of studies on ophistomotoid fungi in Russia. Intensive investigations of ophiostomoid fungi in all countries of Northern Eurasia can be explained by their vast economic significance. V. N. Sukachev Institute of Forest, Siberian Branch of the Russian Academy of Sciences is the only one research institution in Russian Federation where these studies are implementing in full scale. A list of phytopathogens associated with main pests of Siberian forests is compiled; ecological peculiarities of their interactions were studied. Such species as Ips typographus, Ips subelongatus, Tomicus piniperda, Ips acuminatus and Monochamus urussovi are among these pests. Nowadays multidiscipline study on interaction within an invasive complex of four eyed fir bark beetle Polygraphus proximus and few associates fungal species on firs is conducted. Its’ results will help to understand adaptation mechanisms of both groups of invaders (bark beetles and fungi) to the new environment.
