I. INTRODUCTION:
THIS REPORT SUMMARIZES progress 4. Integrated control of pecan pests;
made on various research objectives in 1997
and presents plans for 1998. 5. Strategies for managing crop insects,
emphasizing the cotton agroecosystem,
Many of the results are preliminary and others pesticide effectiveness, and Bt resistance
are being released through established monitoring and management;
channels. Therefore, this report is not
intended for publication and should not be 6. Host plant resistance in soybean pests; and
referred to in literature citations.
7. Rearing of seven insect species in support
The intent of this report is to give the reader of research around the world.
an overview of Southern Insect Management
Research Unit (SIMRU) activities. These This report is divided into four sections:
activities (progress and plans) address the
research unit mission (listed on page 2). 1. Report on research progress in CY 1997;
SIMRU activities are centered around seven 2. List of publications including those in
research thrusts, which reflect present CRIS press and accepted for publication;
