Mark S. Hoddle

Mark S. Hoddle is a Professor of Entomology and Biological Control Specialist at the University of California, Riverside (UCR), where he has headed research in his laboratory since 1997. He serves as the Director of the Center for Invasive Species Research and is a Principal Investigator focusing on biological control of invasive pests. His work bridges academic research with practical applications for California agriculture.

Education:

• D.Sc. Zoology (2018), University of Auckland, New Zealand
• Ph.D. Entomology (1996), University of Massachusetts, Amherst
• M.S. Zoology (1991), University of Auckland, New Zealand
• B.S. Zoology (1988), University of Auckland, New Zealand

Dr. Hoddle specializes in biological control, the intentional use of host-specific natural enemies to suppress pest populations. His research focuses on identifying pest problems amenable to biological control, locating and releasing natural enemies, and evaluating their impact on pest population growth. He works extensively with invasive species affecting California agriculture, particularly pests of citrus, avocado, palm trees, and other crops. His approach combines field evaluations with laboratory studies of pest and natural enemy biology and behavior.

Analysis of Dr. Hoddle's recent publications reveals a strong focus on invasive species threatening California agriculture, particularly the Asian citrus psyllid, red palm weevil, and brown marmorated stink bug. His research integrates field and laboratory approaches, with emphasis on phenology modeling, natural enemy evaluation, and innovative control methods. Much of his work addresses the economic and ecological impacts of invasive pests on specialty crops.

Scientific Awards:

• Entomological Society of America, Pacific Branch Entomology Team Leader Award (2023)
• UC-ANR Distinguished Service Award for Outstanding Research (2022)
• Fellow, Entomological Society of America (2018)
• California Department of Pesticide Regulations IPM Achievement Award for Asian Citrus Psyllid Biocontrol (2018)
• IOBC Distinguished Scientist of the Year (2015)
• Multiple awards from the Entomological Society of America (2007, 2012, 2013, 2014)

Dr. Hoddle has mentored numerous students and researchers throughout his career, including postdoctoral scholars and specialists who contribute to his laboratory's work on invasive species. His research has been supported by various granting agencies, private institutions, and commodity boards, enabling extensive international projects focused on identifying and implementing biological control solutions for invasive pests. He has facilitated the Harry Scott Smith Scholarship Fund to support graduate students in biological control.

Dr. Hoddle directs the Center for Invasive Species Research at UCR and leads a productive laboratory team that includes postdoctoral scholars, specialists, and students. The lab conducts research on multiple invasive species threatening California agriculture and natural ecosystems, with particular emphasis on citrus, avocado, and palm tree pests. Current projects include proactive biological control of the spotted lanternfly and research on invasive palm weevils, avocado pests, and other emerging threats.
