A man, though he did not accumulate any great wealth, who supported, protected, and cared for his family as best he could, and who placed a premium on education for his children; that is his enduring legacy. I dedicate this dissertation to the memory of Harold Ivey; a quiet man; a good husband; a good father. My father. ii Reproduced with permission of the copyright owner.

Acknowledgments One of the many lessons that I have learned while pursuing this degree is that there is no such thing as "a self-made man"; many persons have helped me to successfully complete this degree. My major professor. Dr. Seth James Johnson, has been very helpful. He has patiently, tactfully, and tenaciously guided me in the ways of science: generating ideas and testing them against facts, attention to details, critical thinking, scholarship, clarity of expression, and discipline; and sought to instill in me the higher levels of learning: analysis, evaluation, and synthesis. In addition, he was very instrumental in my getting a two-year tuition waiver award. It is difficult, indeed impossible, to exaggerate the gratitude that I extend to Dr. Johnson for his assistance and guidance in helping me make the best of my limited intellectual endowments. I thank the members of my advisory committee - Professors Jerry B. Graves, Thomas J. Riley, Richard N. Story, and Paul H. Templet (Institute for Environmental Studies) - for their many constructive comments, suggestions, and reviews of my research work. Thanks also to Professor Abner M. Hammond for loaning me some of his pesticide application equipment.

Education (formerly College of Agriculture), Jamaica, also are deserving of my thanks for their help with the portion of my work done in Jamaica. So too is Mr. Timothy Raiford and the field staff at Burden Research Plantation, Louisiana Agricultural Experiment Station, Baton Rouge, for their help with the part of my research conducted in Louisiana. X am thankful to the Department of Entomology, Louisiana State University, and especially its head, Dr. Frank Guillot, for financial assistance in the form of an assistantship. The Environmental Foundation of Jamaica (EFJ) provided substantial financial support for the studies I did in Jamaica. I am very grateful to the former Executive Director of the EFJ, Dr. Terrence Thomas, for his help and encouragement. Mr. Lenworth Fulton, Managing Director of the College of Agriculture Jamaica Foundation, also contributed to my success by assisting with the cost of my accommodation for the duration of the studies I did in Jamaica. Earlier in my life, Mrs. Marjorie Jackson provided me with guidance and direction for which I am very grateful. Also, Mr. Ralston Munn and Mrs. Floribel Morris-Barrett gave me opportunities which helped me to get on the path that led to where I am today; I thank them both. Thanks also to my family members, especially my mother, Mrs. Enid Ivey, and friends who have provided moral support iv Reproduced with permission of the copyright owner.
