INFORMATION TO USERS While the most advanced technology has been used to photograph and reproduce this manuscript, the quality of the reproduction is heavily dependent upon the quality of the material submitted. For example: • Manuscript pages may have indistinct print. In such cases, the best available copy has been filmed. • Manuscripts may not always be complete. In such cases, a note will indicate that it is not possible to obtain missing pages. • Copyrighted material may have been removed from the manuscript. In such cases, a note will indicate the deletion. Oversize materials (e.g., maps, drawings, and charts) are photographed by sectioning the original, beginning at the upper left-hand corner and continuing from left to right in equal sections with small overlaps. Each oversize page is also filmed as one exposure and is available, for an additional charge, as a standard 35mm slide or as a 17”x 23” black and white photographic print. Most photographs reproduce acceptably on positive microfilm or microfiche but lack the clarity on xerographic copies made from the microfilm. For an additional charge, 35mm slides of 6”x 9” black and white photographic prints are available for any photographs or illustrations that cannot be reproduced satisfactorily by xerography.

Hollay B.S,, University of Illinois, Urbana-Champaign, 1977 M.S., Purdue University, 1980 May 1987 ACKNOWLEDGMENTS I thank the members of my advisory committee, Drs. C. M. Smith, my major professor, L. D. Newsom, and E. A. Heinrichs of the Department of Entomology, J. F. Robinson, USDA-ARS and Elaine Nowick of the Rice Research Station at Crowley, and V. L. Wright of the Department of Experimental Statistics, for their guidance. I also thank Drs. J. B. Graves of the Department of Entomology, M. C. Rush of the Department of Plant Pathology and Crop Physiology, J. P. Geaghan of the Department of Experimental Statistics, the late P. E. Schilling, Dean of Agriculture, and W. 0. Mcllrath, USDA-ARS for their contributions. 1 especially thank Dr. L. D. Newsom for sharing his wisdom, unbridled optimism and help in keeping things in perspective. What an inspiration! I am very appreciative of all the good advice and ideas given to me by Dr. J. F. Robinson, who also supervised me while I conducted my research at the Rice Research Station. 1 thank all the members of the Entomology Laboratory at the Rice Research Station, especially George Trahan, for their help. To all the people at the Rice Research Station, thank you for putting up with "that graduate student". Finally, I like to thank all my friends who helped me survive to this point, and to my family, especially my mother, for all her encouragement and financial support during difficult times. ii TABLE OF CONTENTS Page ACKNOWLEDGEMENTS ............................................. ii TABLE OF C O N T E N T S .............................. iii LIST OF T A B L E S ................................................. vi LIST OF FIGURES ...............................................xii ABSTRACT............................................... .xiii INTRODUCTION ................................................. 1 References Cited ........................................ 3 REVIEW OF LITERATURE ......................................... 5 References Cited ........................................ 16 CHAPTER I Structure and formation of feeding sheaths of the rice stink bug (Hemiptera: Pentatomidae) on rice grain and their association with fungi............................. 25 A b s t r a c t ................................................. 26 Introduction ........................................... 26 Methods and Materials................................... 27 Results ..............................................28 D i s c u s s i o n ............................................... 28 References Cited ........................................ 37 CHAPTER II Toxicity of the fungicide propriconazol to rice stink bug adults........................ 39 Abstract ............................................ 40 Introduction ........................................... 40 Methods and Materials................ 41 iii TABLE OF CONTENTS (continued) Page Results . .............................................. 42 D i s c u s s i o n ............................................... 44 References Cited ....................................... 46 CHAPTER III The effects of rice stink bug, (Hemiptera: Pentatomidae), grain spotting fungi, and panicle age on full grain weight and pecky kernels in rice............................ 47 A b s t r a c t ............... ................................ 48 Introduction........................ 48 Methods and Materials .................................... 49 Results . ........... 52 D i s c u s s i o n ............................................... 60 References Cited ....................................... 65 CHAPTER IV A screening method for detecting tolerance in rice to the rice stink bug, (Hemiptera: Pentatomidae). ............. 67 A b s t r a c t ................................................. 68 Introduction.............................. 69 Materials and Methods .................................... 70 Results................................................... 75 Discussion ......................................... 83 References Cited ....................................... 89 CHAPTER V Evaluation of rice lines for resistance to rice stink bugs. .................................... 91 iv TABLE OF CONTENTS (continued) Page A b s t r a c t ................................................. 92 Introduction ........................................... 92 Materials and Methods .................................... 93 Results..................................... 96 D i s c u s s i o n .............................................. 112 References Cited......................................... 120 CHAPTER VI Evaluation of Penn-cap M for rice stink bug control in rice. 122 A b s t r a c t ................................................ 123 Introduction ........................................... 123 Materials and Methods......... 124 Results....................................... 125 D i s c u s s i o n .............................................. 128 References Cited... ...................................... 130 CONCLUSIONS .................................................. 132 APPENDIX A .................................................... 134 APPENDIX B .................................................... 137 APPENDIX C .................................................... 143 APPENDIX D ...................................................
