Herbivorous insects interaction with entomopathogenic fungi (based on species of Hymenoptera and Lepidoptera orders) /

Lepidoptera and Hymenoptera are the major orders of pests. Chemical pest control is still the predominant type of pest control today. One of alternatives to chemical insecticides is the use of biological preparations based on entomopathogenic fungi. The aim of the research was to determine the diversity of entomopathogenic fungi in the natural population of conifer defoliators, to establish sensitivity of these insects to entomopathogenic fungi and to test insect ability to recognise fungus-infected substrates. The results based on the model species from Hymenoptera and Lepidoptera orders have expanded the knowledge of economically important conifer pests - Bupalus piniaria, Dendrolimus pini, Diprion pini ecology and interfaces with pathogenic fungi complex. It has also been estimated insects (Plodia interpunctella) chemoreception on fungi infected and uninfected substrates. For the first time shown that insect not only distinguishes the substrate for eggs laying, but also evaluates its quality. It was found for the first time that 4-oxoisophorone can affect mated Plodia interpunctella females as a repellent and 3-methyl-1-butanol acts both as a repellent (in high doses) and as an attractant (in lower doses). It was proved for the first time that 3-methyl-1-butanol can be a marker to recognise fungus-infected substrates.
