European corn borer control with Bacillus thuringiensis standardized as corn borer international units
TLDR
Bacillus thuringiensis products (Dipel and Thuricide HPC) were standardized against the European corn borer by using standard bioassay techniques and gave better control of thecorn borer than did the spray formulations.About:

Toxicity of Bacillus thuringiensis Spo Cr Mutants for the European Corn Borer Ostrinia nubilalis.
TL;DR: Inclusion bodies isolated from Spo Cr mutants of Bacillus thuringiensis were toxic for larvae of the European corn borer, and inclusion bodies pretreated with alpha-chymotrypsinogen were equally as toxic as native crystals for the insect larvae.

A proposed standardized bioassay for formulations of Bacillus thuringiensis based on the international unit.
TL;DR: A bioassay based on the international unit and using the cabbage looper, Trichoplusia ni, is proposed to fulfill the requirement for standardization of preparations of Bacillus thuringiensis containing the δ-endotoxin by spore count alone.
