Snyder In Partial Fulfillment of the Requirements for the Degree of Master of Science December 2016 Purdue University West Lafayette, Indiana ii ACKNOWLEDGMENTS First, I would like to thank my advisor and head of my graduate committee, Dr. Jennifer Zaspel and the remaining members of my committee, Dr. Catherine Hill and Dr. Stephen Cameron for their scientific guidance and financial support. I would also like to thank Dr. Alberto Zilli, Dr. Pete Pascuzzi, Dr. Jeffrey Holland, Dr. Eugenio Nearns, and Adam Alford for all their support and training in various techniques I used throughout my study. I graciously acknowledge all the individuals and institutions that provided data vital to this study. I would also like to thank Dr. Ian Kaplan and Michael Garvey for providing space and equipment necessary for rearing specimens. I appreciate the assistance from Brigette Zacharczenko with the acquisition of specimens and Samuel Jaffe for obtaining eggs and larval material. I thank Dr. Sharon Hill and Dr. Rickard Ignell (Swedish University of Agricultural Sciences) for assistance with providing chemosensory gene sequence data, and the Purdue Genomics Core for transcriptome assembly. This work would not have been possible without the support and encouragement from my family, Ryan Buffone and my lab mates; Timothy Anderson, Gareth Powell, and Crystal Purcell. This work was supported in part by the Prairie Biotic Research Inc. (PBR), Agriculture Research at Purdue (ARP), Purdue University College of Agriculture iii and a Research and Exploration grant from the National Geographic Society to Zaspel (2008). iv TABLE OF CONTENTS Page LIST OF TABLES ........................................................................................................... vii LIST OF FIGURES ......................................................................................................... viii ABSTRACT ........................................................................................................................ x CHAPTER 1.
