ABSTRACT
Paula and Blanche now have a great system: Paula plans the experiments, Blanche completes the bioassays, and Paula does the data analyses. Or, as Blanche puts it, she does all the work and Paula thinks a lot. Once the laboratory colony has been well-established, Blanche does repetitive bioassays with three chemicals representative of different chemical classes, and a standard preparation of the microbial toxicant
Bacillus thuringiensis
subsp.
