Abstract:
Aphids transmit some 300 plant viruses that result in considerable economic loss within the agricultural sector. Viruses within the family 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 incompletely 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 allowing for transgenic plant resistance to aphids.
Bryony C. Bonning
Dr. Bryony C. Bonning is a professor of entomology at Iowa State University where she is Director of the Center for Arthropod Management Technologies (CAMTech), a National Science Foundation Industry / University Cooperative Research Center that was founded in 2013. Bonning received her B.Sc. in Zoology from the University of Durham, UK and Ph.D. in Entomology from the London School of Hygiene and Tropical Medicine, University of London, UK. She went on to postdoctoral appointments at the Natural Environment Research Council Institute of Virology in Oxford, UK and at the University of California, Davis, USA. 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. Her desire to see delivery of novel pest management solutions played a large part in her authorship of five patents and in the establishment of CAMTech to better align research conducted within academe with the need of industry for practical pest management solutions. Bonning has published more than 110 scientific papers, reviews and book chapters on diverse subjects including insecticidal toxins derived from Bacillus thuringiensis (Bt), genetic optimization of insect viruses for pest management, insect virus discovery and the development of insect resistant transgenic plants. A native of England, she is a Fellow of the Entomological Society of America and of the American Association for the Advancement of Science, and recipient of the 2013 Nan-Yao Su Award for Innovation and Creativity in Entomology.
