Detection of the toxicity of a micromycetes series - the Helicoverpa armigera pathogens

The issue of the presence of micromycetes that cause diseases of caterpillars of one of the most dangerous pests of Gossypium - Helicoverpa armigera (Hübner, 1808), is discussed. In 2020-2021 20 species of micromycetes were identified and isolated in a pure culture. These cultures artificially infected 50 wax moth caterpillars. As a result, only 2-4% of dead caterpillars were noted. These strains of fungi are pathogens and have entomopathogenic properties but are of no practical interest.
