2023 Fellows of the Entomological Society of America

Cassandra Extavour, Ph.D.Cassandra Extavour, Ph.D., a Howard Hughes Medical Institute Investigator and Timken Professor of Organismic and Evolutionary Biology and of Molecular and Cellular Biology at Harvard University, was elected as a Fellow in 2023. Extavour a native of Toronto, where she attended the University of Toronto Schools and went on to obtain an Honors BSc at the University of Toronto with a specialization in molecular genetics and molecular biology, a major in mathematics and a minor in Spanish. She obtained her Ph.D. with Antonio Garcia Bellido, Ph.D., at the Severo Ochoa Center for Molecular Biology at the Autonomous University of Madrid. She performed postdoctoral work first with Michalis Averoff, Ph.D., at the Institute for Molecular Biology and Biotechnology in Crete, Greece, and subsequently with Michael Akam, Ph.D., at the University of Cambridge. At Cambridge she received a BBSRC research grant and became a research associate in the Department of Zoology. In 2007 she established her independent laboratory as an assistant professor in the Department of Organismic and Evolutionary Biology at Harvard University, where she was promoted to associate professor in 2011 and to full professor in 2014. In 2021 she became a Howard Hughes Medical Institute Investigator and was named the Timken Professor of Organismic and Evolutionary Biology and of Molecular and Cellular Biology at Harvard.

Extavour has received numerous honors and awards, including the NSERC Canada, Trinity College and Edward Blake Admissions Scholarships, and the Robert Philips Award for Excellence in Spanish as an undergraduate student; a graduate training fellowship of the Spanish Ministry of Science and Research as a graduate student; the EMBO Short Term Fellowship as a postdoctoral researcher, and the Ellison Medical Foundation New Scholar in Aging Award as an assistant professor. For her teaching and mentoring activities, she has been nominated for the Joseph R. Levenson Memorial Teaching Prize and the Harvard Graduate Women in Science and Engineering Mentoring Award. In 2020 she was named a Harvard College Professor in recognition of her contributions to mentoring and teaching at Harvard.

Extavour began working on germ cell development in graduate school. In her Ph.D. thesis, she used classical Drosophila genetics to explore the genetic requirements of germ cells during development. Using clonal analysis, she showed that primordial germ cells engage in cell-cell competition prior to gametogenesis, revealing a level of natural selection that operates not only pre-zygotically but in the very precursors of gametes themselves. This means that allele frequencies can potentially be changed from one generation to the next, not only by natural selection operating on sexually mature adult individuals but also on the cells responsible for producing the gametes that will ultimately give rise to those individuals. Because of the critical role of germ cells not only in development but also in evolution, her subsequent work has focused on germ cell development in a comparative context.

The Extavour laboratory is interested in understanding early embryonic development, the genes that control this development, the evolutionary origins of these genes, and how their functions have changed over evolutionary time. The lab is particularly interested in the development and evolution of reproductive systems, including both germ cells, which are cells that make eggs and sperm in sexually reproducing animals, and somatic gonad cells, which create the structures to house and protect the germ cells and regulate egg and sperm production.

James Hagler, Ph.D.James Hagler, Ph.D., research entomologist at the U.S. Department of Agriculture-Agricultural Research Service (USDA-ARS) Arid Land Agricultural Research Center in Maricopa, Arizona, was elected as a Fellow in 2023. Hagler pioneered the development of the protein immunomarking procedure for use in arthropod area-wide dispersal research. He is also internationally recognized for his research on arthropod molecular gut content analysis, conservation biological control, cultural control, and insect behavior.

Hagler grew up in Albuquerque, New Mexico. He earned his B.S. and M.S. degrees at New Mexico State University in 1982 and 1985 and his Ph.D. in 1988 at the University of Arizona. He joined the USDA-ARS in 1988 as a postdoctoral research associate, and then as a research entomologist at the Western Cotton Research Laboratory in Phoenix, Arizona, from 1996 to 2005. In 2006, the WCRL relocated to the Arid-Land Agricultural Research Center in Maricopa, Arizona, where Hagler worked for the remainder of his career.

Alvin M. Simmons, Ph.D.Alvin M. Simmons, Ph.D., research entomologist at the U.S. Department of Agriculture-Agricultural Research Service (USDA-ARS) U.S. Vegetable Laboratory (USVL) in Charleston, South Carolina, was elected as a Fellow in 2023. He is internationally known for his work on integrated pest management in crops.

Simmons was born in New Bern, North Carolina, in 1957 and grew up on a small family farm. He received a B.S. in biology from East Carolina University (1980) and an M.S. (1983) and Ph.D. (1987) in entomology from the University of Kentucky. After graduation and four months of postdoctoral research at the University of Kentucky, he joined USDA-ARS in Tifton, Georgia, where he conducted three years of postdoctoral research and then accepted a permanent appointment in 1990. He transferred to the USVL in 1992 to address a congressional mandate on whiteflies. Shortly thereafter, he also assumed responsibility for an in-house project supporting the registration of pest control products in cooperation with the national IR-4 Project. In 2017, he was also appointed USDA-ARS coordinator for the Minor Use Pesticide Program for Food and Ornamental Horticulture, which concerns research by ARS in cooperation with the IR-4 Project to support the registration of pest control products for specialty crops (e.g., fruits, nuts, vegetables, herbs, and floral) and minor use on major crops. He served on details as acting research leader and location coordinator for the former USDA-ARS Phil Campbell Natural Resource Conservation Center in Watkinsville, Georgia, in 2011, and for the USVL in 2019. 

Simmons has published over 175 articles, including seven book chapters, and co-released five breeding lines; he has also provided over 350 technical reports. His documented research subjects include host plant resistance, insect behavior and bionomics, geonomics, biocontrol, cultural control, biopesticides, pesticide resistance, and insect-virus-plant relationships. He has given over 250 research talks to domestic and international audiences. His research contributed to the registration of numerous pest control products. The USDA-ARS team of researchers that he leads results in an estimated annual impact of $1.3 billion gross domestic product.

Simmons has provided leadership in entomology including serving as president of ESA (2019-2020); president of the Entomological Foundation (2018-2019); president of the South Carolina Entomological Society (2018-2019); co-chair (with Walter Leal, Ph.D.) of the 2016 International Congress of Entomology (2012-2016), the largest gathering of entomologists to date; member of the Entomological Foundation Board of Counselors (2005-2016); president of the ESA Southeastern Branch (2008-2009); and member of numerous committees. He has received  many recognitions including ESA Recognition Award in Entomology, the ESA Southeastern Branch Award for Excellence in Integrated Pest Management, IR-4 Meritorious Award, University of Kentucky Department of Entomology Distinguished Alumni Award (first recipient), Fellow of the Royal Entomological Society, Honorary Member of ESA, Sigma Xi lifetime member, Gamma Sigma Delta lifetime member, Community Service Award in Agricultural Research & Education, and USDA-ARS Outreach, Diversity, and Equal Opportunity Award.

Married to his wife Edith for 20 years, they supported their first-born, Princess (7th grade), to present her first ESA annual meeting paper in 2022 and her second ESA meeting paper in 2023 along with co-author Duchess, their other child (3rd grade).

Lukasz Stelinski, Ph.D.Lukasz Stelinski, Ph.D., professor of entomology and nematology at the University of Florida's Citrus Research and Education Center, was elected as a Fellow in 2023. A consistent area of research focus has been the practical applications of semiochemicals for pest management, particularly in the area of mating disruption. His research has contributed to the development of a theoretical framework for understanding mating disruption mechanisms in insects. Stelinski played a role in evaluating and refining practical technologies for releasing semiochemicals in crops, leading to the development of now widely available tools. In recognition of his contributions to applications of chemical ecology for pest control, he was elected as a fellow of the American Association for the Advancement of Science in 2022.

Currently, Stelinski's research involves investigating the interactions between phytopathogens and their vectors, aiming to develop sustainable management systems for crop production in response to disease invasions. His work on citrus greening disease, which heavily impacts Florida's orange juice trees, has involved managing vector populations and addressing issues such as insecticide resistance.

For example, his lab unraveled the mechanisms conferring insecticide resistance in citrus psyllid populations and developed appropriate remediation strategies. Grower adoption of revised insecticide application schedules eliminated the problem of neonicotinoid and pyrethroid resistance among psyllid populations in Florida citrus almost entirely.

Stelinski's research on plant-insect interactions has revealed the impact of citrus psyllid feeding on plant immunity and growth. Through his studies, he has determined that suppressing vector populations can lead to measurable yield gains, particularly when disease is widespread. In this case, his findings have revealed the utility of incorporating threshold-based management strategies for vectors, reducing unnecessary insecticide sprays while maintaining yield and increasing grower profit.

Stelinski's research has also influenced cultural control methods for disease management in citrus. His team demonstrated the effectiveness of establishing living windbreaks and replacing individual diseased trees instead of replanting entire orchards. Additionally, his research on psyllid vector movement has contributed to the reduction of abandoned orchards in Florida, which serves as a source of disease inoculum.

With nearly 240 peer-reviewed journal articles and over $16 million in grant support, Stelinski has greatly benefited from wide ranging collaborations with many colleagues across the globe and has had the good fortune of working with many brilliant students and postdocs, all of whom have greatly contributed to his lab's success. Those students and postdocs are now active in academia, industry, and the U.S. government. Stelinski is involved in teaching courses and seminars on pest management, chemical ecology, and professional development in entomology, and he actively promotes the implementation of biorational solutions to pest management through his extension program.

Edward L. Vargo, Ph.D.Edward L. Vargo, Ph.D., professor and endowed chair in urban entomology at Texas A&M University, was elected as a Fellow in 2023. He is internationally recognized for research in the reproductive biology and molecular ecology of social insects and urban insect pests.
