Interpretive Summary:

Technical Abstract: Bacillus thuringiensis is being explored as a biological control agent for Diaprepes abbreviatus. A collection of potentially active isolates was assembled for testing against weevil larvae. The collection contains patented isolates and others isolated from field-collected weevil larvae. Significant activity was observed for some isolates in feeding bioassays against weevil larvae. Effective rates were determined for active isolates. Novel B. thuringiensis endotoxins discovered may be used to develop transgenic approaches to control as deemed appropriate.
