Abstract
The boxwood moth Cydalima perspectalis Walker is a dangerous adventive pest, the control of numbers and harmfulness of which cannot be carried out by traditional chemical insecticides in forest park sanitary, recreational, protected and resort areas. The article presents the dynamics of the development of the boxwood moth in the Perkalsky Arboretum in the period 2018-2023 and the results of laboratory tests of the spore-based entomopathogenic fungus Akanthomyces muscarius in the form of a wetting powder, strain G - 033 VIZR. The effectiveness of the preparative form was slightly lower than the effectiveness of the standard. It was established that boxwood moth caterpillars of older instars have higher resistance to entomopathogenic fungi compared to larvae of younger instars. The protective effect of entomopathogenic fungi is more pronounced at low and medium pest infestation of plants.
