Bryony Bonning to Discuss - Novel Toxin Delivery Strategies for Management of Pestiferous Aphids
April 11, 2012
DAVIS--Professor Bryony Bonning of Iowa State University's Department of Entomology and a former postdoctoral research associate at UC Davis in the Bruce Hammocklab, will speak on "Novel Toxin Delivery Strategies for Management of Pestiferous Aphids" at the next UC Davis Department of Entomology seminar, set from 12:10 to 1 p.m., Wednesday, April 18 in 122 Briggs Hall.
Professor Bryony Bonning will speak on "Novel Toxin Delivery Strategies for Management of Pestiferous Aphids" on April 18.
From 1990 to 1994, Bonning worked with Hammock, a distinguished professor of entomology, in the UC Davis departments of Entomology and Environmental Toxicology on genetic engineering and optimization of baculovirus insecticides.
Hammock will introduce Bonning at the April 18th seminar. "I can hardly wait for Bryony Bonning to visit us and present a seminar," Hammock said. "She is one of our most productive alumni in continuing her work on insect developmental biology and green pesticides based on insect viruses and expanded this dramatically into exciting new areas. She is advancing fundamental virology while applying this knowledge in production agriculture in both insect control and in blocking transmission of plant diseases by insects. She clearly is the leader in insect control with recombinant viruses.".
Bonning conducts fundamental and applied research on insect physiology and insect pathology with the goal of developing novel, environmentally benign alternatives to chemical insecticides for insect pest management. Her research has included the study of insect hormones and enzymes and insecticide toxins derived from Bacillus thuringiensis, insect small RNA, the genetic optimization of insect viruses for pest management, insect virus discovery and the use of viral proteins for development of insect resistant transgenic plants.
Abstract of her talk:
Aphids transmit more than 275 plant viruses that result in considerable economic loss within the agricultural sector. Viruses in the Luteoviridae are obligately transmitted by aphids in a persistent manner that requires virion accumulation in the aphid hemocoel. To enter the hemocoel, the virion must bind and traverse the aphid gut epithelium. The molecular mechanisms involved in this process are poorly understood. By screening a phage display library, we identified a peptide that binds to the gut epithelium of the pea aphid Acyrthosiphon pisum (Harris) and impedes the update of Pea enation mosaic virus from the pea aphid gut into the hemocoel. In this talk, the development of two novel aphid management technologies based on knowledge of pea aphid – Pea enation mosaic virus molecular interactions will be described. These technologies provide enhanced delivery of both gut active and neurotoxic peptides.
Bryony Bonning, a professor in the Iowa State University Department of Entomology, joined the faculty in 1994 as an assistant professor and was promoted to associate professor in 2000. As a faculty member, she works with four interdepartmental programs: Microbiology, Toxicology Program, Genetics, and the Molecular, Cellular and Developmental Biology Program. In addition, she serves as the co-director of the Plant Sciences Institute of the Crop Protection Initiative, and is affiliated with the Iowa Center for Advanced Neurotoxicology, and the Center for Plant Responses to Environmental Stresses of the Plant Sciences Institute.
Bonning is an associate editor for the Journal of Invertebrate Pathology; a Fellow of the American Association for the Advancement of Science (AAAS); a member of the International Committee on Taxonomy of Viruses, Baculovirus Study Group; and a member of the International Committee on Taxonomy of Viruses, Dicistrovirus / Iflavirus Study Group.
Bonning received her bachelor's degree in zoology from the University of Durham, UK in 1985, and her doctorate in applied entomology from the London School of Hygiene and Tropical Medicine, University of London, UK in 1989.
While enrolled in college in the UK, she did field work on the detection and monitoring of insecticide resistance mechanisms in mosquitoes with the Anti-Malaria Campaign in Colombo, Sri Lanka; she was funded by the Overseas Development Administration. Bonning also did regional monitoring and field trials for biological or chemical control of arthropod and nematode pests in Derbyshire, UK, with the Department of Entomology, Ministry of Agriculture, Fishers and Food,Agricultural Development and Advisory Service.
After receiving her doctorate from the University of London, Bonning worked from 1989 to 1990 as a higher scientific officer with the Natural Environment Research Council (NERC) Institute of Virology and Environmental Microbiology, Oxford. Later she worked in genetic engineering of baculovirus insecticides in the Robert Possee lab before heading to California to join the Hammock lab as a postdoctoral researcher.
Coordinators of the spring seminars are Louie Yang and Joanna Chiu, assistant professors. All lectures will take place on Wednesdays from 12:10 to 1 p.m. in 122 Briggs Hall. The series, launched April 4, will continue through May 23.
In a webcast project coordinated by professor James R. Carey, some of the seminars will be videotaped and can be accessed at a later date on UCTV.
