Isolation of multiple subspecies of Bacillus thuringiensis from a population of the European sunflower moth, Homoeosoma nebulella
Article Abstract:
The larvae of a laboratory colony of the European sunflower moth Homoeosoma nebulella contain five subspecies (subspp.) of Bacillus thuringiensis that produce different insecticidal proteins. The subspp. thuringiensis produces spherical crystals, thompsoni produces pyramidal crystals while the other subspp. produce bipyramidal crystals. The thuringiensis, aizawai and kurstaki subspp. are toxic to H. nebulella and are potential agents for use against this insect.

Binding of Cyt1Aa and Cry11Aa toxins of Bacillus thuringiensis serovar israelensis to brush border membrane vesicles of Tipula paludosa (Diptera: Nematocera) and subsequent pore formation
Article Abstract:
The binding of crystal proteins, including Cyt1Aa and Cry11Aa toxins of Bacillus thuringiensis serovar israelensis to brush border membrane vesicles of Tipula paludosa (Diptera: Nematocera) is being explained. The reaction leads to high efficiency of pore formation, exhibiting a reduced activity of the Cry11Aa substrate.

A binding site for Bacillus thuringiensis Cry1Ab toxin is lost during larval development in two forest pests
Article Abstract:
Two forest pests appear to become partially resistant to the insect toxins produced by Bacillus thuringiensis. Both Thaumetopoea pityocampa and Lymantria monacha lose binding sites for the Cry1Ab toxin during larval development.
