KEY NOTE SPEAKERS AND SCIENTIFIC CONTRIBUTIONS
Dr. Anthony M. Shelton (International Professor, Department of Entomology & Assoc. Director of International Programs, Cornell University/NYSAES, USA)
Title: The Talekar Challenge: What Have We Learned and Where Are We Going with Practical DBM Research and Extension since 1985?
Dr. N.S. Talekar, an entomologist from AVRDC, was the workshop coordinator and editor of the proceedings for the first (1985) and second (1990) International Workshops on Diamondback Moth, both held in Tainan, Taiwan. For the occasion of the first and second conferences, Talekar also published an annotated bibliography which he made freely available to scientists worldwide. In 1993 he was the senior author of the first comprehensive review of diamondback moth (DBM). Talekar has been an active researcher and promoter of applied entomology and biological control for insect pests on crucifers and other vegetables. His work and leadership continues to inspire us as we address the continuing challenges of managing DBM in the varied cropping systems globally. These challenges include: the continuing development of resistance to insecticides and applying strategies to delay the evolution of resistance; understanding the role biological control plays in reducing DBM populations and how biological control can be enhanced; utilizing the information from the DBM genome for creating useful management strategies; developing a better understanding of DBM ecology on a landscape level; researching genetic control strategies including modifying the insect and its host plants, and; creating practical outreach programs that enable farmers to manage DBM in a more sustainable manner.
Dr. Michael Furlong (Senior Lecturer in School of Biological Sciences, University of Queensland, St Lucia, Queensland, Australia)
Title: Biological control of diamondback moth in a climate of change
Dr. Mike Furlong's research focuses on the biological control and integrated management of insect pests. Externally funded research projects concentrate on the development of sustainable pest management strategies for insect pests in developing countries. In Indonesia the structure and function of the natural enemy complexes attacking the diamondback moth (Plutella xylostella) and the large cabbage moth (Crocidolomia pavonana) are being determined. In Samoa the biology and ecology of the egg parasitoid Trichogramma chilonis is being investigated and the possibility of its release as a biological control agent of C. pavonana in Fiji, Tonga and Solomon Islands explored. Research in Fiji, Tonga and Samoa is focused on quantifying field resistance of the diamondback moth to commonly used insecticides. An insecticide resistance management strategy has been developed and implemented in collaboration with UN-FAO.
Prof. Dr. David G. Heckel (Director, Max Planck Institute for Chemical Ecology, Jena, Germany)
Title: Molecular aspects of insecticide resistance in the diamondback moth
Prof. David Heckel studies the genetic and molecular basis of insect adaptations to stress, including antiherbivore defenses of host plants, chemical insecticides, and bacterial toxins. He also is interested in evolution of the sexual pheromone communication systems of lepidoptera, and in the evolution of host-races and processes of adaptation to new plant hosts. His presentation will summarize current knowledge of insecticide resistance in diamondback moth, its genetic and molecular basis, and the potential of the newly-determined genome sequence to contribute to these studies.
Dr Nancy Schellhorn obtained her PhD from University of Minnesota, USA. She conducted post-doctoral research (1998) at University of Wisconsin-Madison USA on interactions among multiple species of exotic and native arthropods, and (2000) at CSIRO Narrabri, NSW on parasitoids of Helicoverpaspp on cotton. In late 2000 she joined SARDI, where she lead the National Diamondback Moth project, and Revegetation by Design project. In 2005, Dr Schellhorn joined CSIRO in Brisbane where she is a Principle Research Scientist and leads the Spatial Ecology Team in Brisbane.
Nancy’s research uses ecological concepts to address pest management problems at multiple spatial and temporal scales in agricultural and urban landscapes. She and her collaborators have developed and advanced the concept of Pest Suppressive Landscapes, which is a way of measuring, designing and managing agricultural landscapes for productivity and biodiversity.
