European honey bee workers and drones showed consistent GC pat- terns. Race-specific similarities in GC patterns were present in Africanized workers and drones from Central and South America.

  • Comparing University Entomology Outreach Events While Examining Public Views of Arthropods and Pesticides
    Comparing University Entomology Outreach Events While Examining Public Views of Arthropods and Pesticides Stephanie Lynn Blevins Thesis submitted to the faculty of the Virginia Polytechnic Institute and State University in partial fulfillment of the requirements for the degree of Master of Science in the Life Sciences In Entomology Michael J. Weaver, Chair Paul Marek Tonya Price August 23, 2018 Blacksburg, VA Keywords: Entomology, university outreach, public views, arthropods, pesticides Copyright © 2018 Stephanie Lynn Blevins Comparing University Entomology Outreach Events While Examining Public Views of Arthropods and Pesticides Stephanie Lynn Blevins Academic Abstract Hokie BugFest is an annual free event designed by the Entomology Department at Virginia Tech to translate the importance of entomology to the public. The event has grown from 2,000 attendees in 2011 to over 8,000 attendees in 2017. Entomology faculty, staff, graduate students and alumni partner with Virginia Cooperative Extension, Virginia 4-H, and other entities to provide an educational experience to the public. The goal of this outreach event is to showcase entomological research, increase public awareness, elevate the appreciation of entomology, develop better public perceptions of insects and other arthropods, and educate participants about pesticide safety and pest management practices. Although many institutions host entomology outreach events like Hokie BugFest (Frazier, 2002; Hamm & Rayor, 2007; Hvenegaard et al., 2013), little research has been conducted to compare the impact of these activities. Whether these events impact public attitudes toward insects and other arthropods is also lacking (Pitt & Shockley, 2014). Several studies have been conducted in other states to investigate public attitudes toward arthropods and pesticides (Baldwin et al., 2008; Byrne et al., 1984; Frankie & Levenson, 1978; Hahn & Ascerno, 1991; Potter & Bessin, 1998); however, research is missing in Virginia.

  • The Effect of the Tsetse Fly on African Development (Job Market Paper)
    The E¤ect of the TseTse Fly on African Development (Job Market Paper) Marcella Alsany October 29, 2012 Abstract The TseTse ‡y is unique to the African continent and transmits a parasite harmful to humans and lethal to livestock. This paper tests the hypothesis that the presence of the TseTse reduced the ability of Africans to generate an agricultural surplus his- torically by limiting the use of domesticated animals and inhibiting the adoption of animal-powered technologies. To identify the e¤ects of the ‡y, a TseTse suitability index (TSI) is created using insect physiology to model insect population dynamics. African tribes inhabiting TseTse-suitable areas were less likely to use draft animals and the plow, more likely to practice shifting cultivation and indigenous slavery, and had a lower population density in 1700. As a placebo test, the TSI is constructed worldwide and does not have similar explanatory power outside of Africa, where the ‡y does not exist. Current economic performance is a¤ected by the TseTse through its e¤ect on precolonial institutions.

  • A Holobiont Characterization of Reproduction in a Live-Bearing
    A holobiont characterization of reproduction in a live-bearing cockroach, Diploptera punctata A dissertation submitted to the Graduate School of the University of Cincinnati in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the Department of Biological Sciences of the McMicken College of Arts and Sciences By Emily C. Jennings B.S. Neurobiology, University of Cincinnati, April 2013 Committee Chair: Joshua B. Benoit, Ph.D. Abstract Viviparous reproduction is characterized by maternal retention of developing offspring within the reproductive tract during gestation, culminating in live birth. In some cases, a mother will provide nutrition beyond that present in the yolk; this is known as matrotrophic viviparity. While this phenomenon is best associated with mammals, it is observed in insects such as the viviparous cockroach, Diploptera punctata. Female D. punctata carry developing embryos in the brood sac, a reproductive organ that acts as both a uterus and placenta by protecting and providing a nutritive secretion to the intrauterine developing progeny. While the basic physiology and hormonal changes of D. punctata pregnancy have been characterized, little else is known about this phenomenon. This study attempts to broaden the understanding of D. punctata reproduction by using a multi-omics approach to characterize multiple aspects of the holobiome. First, I utilized RNA-seq analysis to characterize molecular changes associated with D. punctata reproduction and provides the most complete gene set to date for this species. A comparison of four stages of the female reproductive cycle revealed unique gene expression profiles corresponding to each stage. Differentially regulated transcripts of interest include the previously identified family of milk proteins, transcripts associated with juvenile hormone metabolism, and other reproduction-associated transcripts.

My PhD journey and plant essential oils research projects in bed bugs would not have been possible in less than 4 years without his regular guidance and feedback on experimental design, hands on training in lab, interpretation of results, grant writing, encouragement for conference presentations and manuscript editing/revision.
