THE INFLUENCE OF CHIRALITY ON THE BEHAVIORAL RESPONSES OF LONGHORNED BEETLES (COLEOPTERA: CERAMBYCIDAE) TO VOLATILE AND CONTACT PHEROMONES by Gabriel P. Hughes A Dissertation Submitted to the Faculty of Purdue University In Partial Fulfillment of the Requirements for the degree of Doctor of Philosophy Department of Entomology West Lafayette, Indiana December 2016 ii THE PURDUE UNIVERSITY GRADUATE SCHOOL STATEMENT OF DISSERTATION APPROVAL Dr. Matthew D. Ginzel, Chair Department of Entomology Dr. Michael E. Scharf Department of Entomology Dr. Clifford S. Sadof Department of Entomology Dr. Richard Meilan Department of Forestry and Natural Resources Approved by: Dr. Stephen L. Cameron Head of the Departmental Graduate Program iv ACKNOWLEDGMENTS I would like to thank God and my family for their tireless help and support as I have pursued my education. I thank my advisor, Dr. Matthew Ginzel, for training me in the ways of a true scientist. I thank my committee members for their support and encouragement. I have many people to thank for their assistance on individual chapters of this dissertation. Chapter 2: I thank the Indiana Department of Natural Resources, Division of Nature Preserves and NICHES Land Trust Corporation for permitting me to collect beetles at Black Rock Barrens Nature Preserve.
