USING MULTIPLE METHODOLOGIES TO UNDERSTAND WITHIN SPECIES VARIABILITY OF ADELGES AND PINEUS (HEMIPTERA: STERNORRHYNCHA) A Thesis Presented by Tav (Hanna) Aronowitz to The Faculty of the Graduate College of The University of Vermont In Partial Fulfillment of the Requirements for the Degree of Master of Science Specializing in Natural Resources May, 2017 Defense Date: March 6, 2016 Thesis Examination Committee: Kimberly Wallin, Ph.D., Advisor Ingi Agnarsson, Ph.D., Chairperson James D. Murdoch, Ph.D. Cynthia J. Forehand, Ph.D., Dean of the Graduate College ABSTRACT The species of two genera in Insecta: Hemiptera: Adelgidae were investigated through the lenses of genetics, morphology, life cycle and host species. The systematics are unclear due to complex life cycles, including multigenerational polymorphism, host switching and cyclical parthenogenesis. I studied the hemlock adelgids, including the nonnative invasive hemlock woolly adelgid on the east coast of the United States, that are currently viewed as a single species.
