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 ER -
