Abstract

A commercial formulation of Bacillus thuringiensis var. kurstaki (BTK) was sprayed aerially in an oak forest in Wayne County, Pennsylvania during May 1990. BTK persisted in foliage for about a wekk in all blocks. The half-life of inactivation, DT50, ranged from 12-22 h. Immunosassay data indicated a shorter duration of persistence (2 d) of the delta endotoxic protein, with DT50 values ranging from 10-15 h. Formulation ingredients present in Foray 48B played a role in the toxicity of BTK to gypsy moth Lymantria dispar larvae. -from Authors
