Abstract
This research report is concerned with: 1). A field application program using encapsulated Bt. The objectives of that program involved spray physics and the delineation of the critical parameters inherent in the delivery of Bt sprays to the microhabitat of the spruce budworm. The field application work was carried out jointly with Dr. Alam Sundaram and the Forest Pest Management Institute (Canada). Most of the data from the field studies will be published in a separate paper with Dr. Sundaram. 2). A laboratory program concerned with stabilization studies on pure Bt and BtI crystals. The laboratory studies on pure Bt and Bti crystals were carried out at the University of Georgia with the objective of providing a baseline system by which environmental parameters adverse to Bt (BtI) could be determined, quantified and controlled.
