Dr. Bryony C. Bonning is an eminent scholar and professor of entomology and nematology at the University of Florida, and Director of the Center for Arthropod Management Technologies (CAMTech), a National Science Foundation Industry/University Cooperative Research Center. Dr. Bonning held postdoctoral appointments at the Natural Environment Research Council Institute of Virology in Oxford, UK and at the University of California, Davis, USA. She then joined the faculty at Iowa State University, and moved to University of Florida in 2017. Bonning oversees cutting edge research on insect physiology and insect pathology with the goal of developing novel, environmentally benign alternatives to chemical insecticides for insect pest management.

Graduate Student

Morgana S. Miranda joined the Bonning lab in January 2024 as a MSc student. Her work focuses on the use of bacterial pesticidal proteins as alternative strategy for management of Asian citrus psyllid, the vector of citrus greening bacteria in the US. Morgana holds a BS in Agronomy from the Federal University of Vicosa in Brazil, where her research focused on insect resistance to chemical pesticides and bacterial pesticidal proteins.

Clebson S. Tavares joined the Bonning lab in 2019 and graduated in 2023 with a PhD in entomology based on his work on the "Midgut surface proteome of Diaphorina citri and toxicity of gut-targeting insecticidal proteins for use in citrus greening management." His previous research focused on insect resistance to transgenic crops expressing Bt toxins. He holds a MS in Entomology and a BS in Agronomy from the Federal University of Vicosa, Brazil. He is continuing in the lab as a postdoctoral fellow to work on Asian citrus psyllid - Liberibacter asiaticus molecular interactions.

Graduate Student

Emily joined the Bonning lab as an undergraduate while completing her BS in biochemistry at UF. During this time, she worked on bioassays of Bt toxins on lepidopterans. She now works in the lab as a graduate student in the Genetics and Genomics PhD program. She works on characterizing the virome of the small hive beetle, studying virus replication in the small hive beetle, and has experience in virus sequence discovery.

Dr. Na Xie received her PhD in Molecular Toxicology and Physiology from the Department of Entomology at Virginia Tech. Her dissertation focused on explaining the multiple resistance associated with the Rdl mutation on the GABAA receptors and investigated the toxicology of muscarinic acetylcholine receptors (mAChRs) in Drosophila melanogaster. She joined the lab in June 2022 to work on Asian citrus psyllids (ACP), with the goal of mitigating the impact of citrus greening. She is excited to broaden her molecular research and insect pest research skills as part of the Bonning Lab.

Biological Scientist IV, Lab Manager

(352) 273-3946

Dr. Ke Wu joined the Bonning lab in August 2021 as lab manager. Ke has nearly 3 decades of molecular biology research experience in subjects including plants, viruses, rodents, and insects. Ke oversees the daily operation of Dr. Bonning’s lab. Dr. Wu's current research focuses on two areas: 1) developing cell culture systems in which replication of Asian citrus psyllid viruses can be studied; 2) Identifying and investigating the functional roles of the cellular components involved in regulating viral replication using reverse genetics techniques, such as those based on CRISPR/Cas9.
