THE TOXIGENE PROPERTIES OF ENTOMOPATHOGENICBACILLUS THURINGIENSIS

Т. І. Патика, В. П. Патика

Abstract

There were analysed the toxigen properties of entomopathogenic bacteria Bacillus thuringiensis with various level of formation entomotoxins (crystal δ-endotoxin, termostable β-exotoxin) with use of test insects of different species (Lepidoptera, Dip- tera, Coleoptera). It is shown that the susceptibility of various taxons of the insects to entomopathogenic preparations is caused by the structure of their active toxins.
