INFORMATION TO USERS This material was produced fro in a microfilm copy of the original document. While the most advanced technological means to photograph and reproduce this document have been used, the quality is heavily dependent upon the quality of the original submitted. The following explanation of techniques is provided to help you understand markings or patterns which mayappear on this reproduction. 1. The sign or "target' for pages apparently lacking from die document photographed is "Misking Page(s)". If it was possible to obtain the missing page(s) or section, they are spliced into the film along with adjacent pages. This may have necess tated cutting thru an image and duplicating adjacent pages to insure you complete continuity. 2. When an image on the film is obliterated with a large round black mark, it is an indication that the photographer suspected that the copy may have moved during exposure and thus cause a blurred image. You will find a good image of the page in the adjacent frame, 3. When a map, drawing or chart, etc., was part of the material being photographed the photographer followed a definite method in "sectioning" the material. It is customary to begin photoing at the upper left hand corner of a large sheet and to continue photoing from left to right in equal sections with a small overlap. If necessary, sectioning is continued again — beginning below the first row and continuing on until complete. 4. The majority of users indicate that the textual content is of greatest value, however, a somewha higher quality reproduction could be made from "photographs" if esse ntial to the understanding of the dissertation. Silver prints of "photograp is" may be ordered at additional charge by writing the Order Departme it, giving the catalog number, title, author and specific pages you wisi reproduced. 5. PLEASE NOTE: Sc me pages may have indistinct print. Filmed as received.

Died May 3, 1977 "A sword is a two-edged life." Christopher James Barry "Because no battle is ever won he said. They are not even fought. The field only reveals to man his own folly and despair, and victory is an illusion of philosophers and fools." Faulkner, The Sound and the F u ty ACKNOWLEDGMENTS I wish to express my appreciation to my advisor, Dr. David G. Nielsen, for his assistance throughout this investigation. I am also indebted to the rest of my reading committee: Dr. John A. Secrist III for allowing me to work with his chemistry group in Columbus; Dr. George F. Shambaugh for his advice on insect electrophysiology and use of equipment; Dr. Lowell R. Nault for his comments and suggestions on insect behavior and experimental analyses; and Dr. David J. Horn for his outlook and inspiring discussions on insect biology. Finally, I wish to thank Lynii E. Scoles for her encouragement and typing of the dissertation, Foster F, Purrington for his assistance in the field and laboratory, and Dr. Robert E. Treece for his sincere interest in my work.
