The quantitative and qualitative composition of volatile organic compounds (VOCs) of human exhaled air, the air environment of various types of entomopathogenic fungi (EPF) of the genus Lecanicillium, used as an alternative to chemical pesticides to protect plants from pests, cabbage moth caterpillars, as well as spined soldier bug from the shield family, was studied using a quadrupole mass spectrometer. The main components found were acetone, acetic acid, and isoprene. These components in human exhalation are significant indicators for non-invasive disease diagnosis. For the first time, sulfur dioxide was found in the composition of VOC EPF, as one of the possible repellents. The caterpillars of cabbage moth secrete exclusively acetic acid. [ABSTRACT FROM AUTHOR]
