ACKNOWLEDGEMENTS 



Producing this dissertation involved the skills of many people 

 and, although I accept full responsibility for its contents, I do not 

 cl aim al 1 the credit. 



I am indebted to the United States Army for providing the 

 opportunity to achieve this long time goal. I gratefully acknowledge 

 the selfless contributions of members of my graduate committee. Dr. 

 Jerry F. Butler, chairman, provided continuous instructional guidance, 

 moral and material support throughout the course of this study. Dr. 

 David G. Young was a true mentor, providing many unanswered questions 

 and the principal direction for my research; his enthusiasm for 

 natural science in general and medical entomology in particular was 

 very contagious. Dr. Stephen G. Zam gave freely of his time and 

 expertise in parasitology and protozoology and offered valuable 

 suggestions. I genuinely appreciate such a rare individual as Dr. A. 

 G. B. Fairchild for his wisdom, historical perspective, and his 

 ability as an editor to make kid gloves from a sow's ear. LTC(P) John 

 Reinert served on the committee for the first year and, in concert 

 with the other committe members, helped outline a demanding schedule 

 of courses. 



Sincere thanks go to Ms. Diana Simon, Mrs. Debra Boyd, and other 

 members of the laboratory staff for the many administrative and 

 logistical details I was able to take for granted. I extend special
