Abstract

Toxicity of Bacillus thuringiensis spores to the tobacco hornworm, Manduca sexta, is described. The numbers of larvae killed were in relation to spore dry weight. At a surface application of 6.8 ng/cm2, there was an 85 percent survival, but less than 50 percent survived at 68.2 ng/cm2. Striking similarity of spores to parasporal crystals is revealed by slope of mortality curves, inhibition of stadial growth, and 50 percent lethal dose values based on protein content.
