Abstract:Fifty-one strains of Bacillus thuringiensis subsp. aizawai were screened for toxicity against the bertha army worm, Mamestra conjigurata Walker. The strain, NRRLHD133 was selected for studies on synergism with other subspecies of B. thuringiensis. HD133 was highly toxic to M. conjigurata compared with the international standard (HD-1- S-1980) and was synergistic with B. thuringiensis subsp. kurstaki (R0262), B. thuringiensis subsp. kenyae (ROSSI), and RD262 plus ROSSI when powderswere fed to 3rd instars in artificialdiet. When the strains were cultured together only HD133 and HDSSI were synergistic.
