Biological Control Plenary Speakers

Biological control in resource-rich and resource-poor environments

Ernest "Del" Delfosse

Biography: Dr. Ernest Delfosse is professor emeritus and former Chairperson of the Department of Entomology at Michigan State University.  Before MSU, he was a National Program Leader with the USDA-Agricultural Research Service (1996-2008); Director of the USDA National Biological Control Institute (1991-1996); Research Scientist with CSIRO in Canberra, Australia (1979-1991); and Research Entomologist and Supervisor at the Lee County Hyacinth Control District in Ft. Myers, Florida (1976-79).  He received a Ph.D. from the University of Florida in 1975, working on biological control of waterhyacinth; a M.SC. from South Dakota State University, working on the impact of ultra-low-volume, aerially applied insecticides on dung fauna; and a B.Sc. in Biology from the University of Louisville.  Dr. Delfosse had 17 invited consultancies with groups such as the Food and Agriculture Organization of the United Nations/International Atomic Energy Agency, the Government of South Africa, the Australian House of Representatives’ Standing Committee on Industry, Science and Technology, USDA, and Bilateral Panels with Mexico; chaired or co-chaired over 40 conferences and workshops; and chaired over 20 grant panels.  He is internationally known for leadership of research teams, and for research on biological control and integrated pest management.  He made > 400 presentations (including 26 keynote addresses and 50 invited presentations), published 115 papers, and developed the phenology-event relatedness testing procedure to clarify physiologicalvs. ecological host range of biological control agents. More recently, Dr. Delfosse led the classical biological control program for the brown marmorated stink bug at MSU, where (as part of a group of university and federal colleagues) he worked on host-specificity testing of the most promising biological control agent for BMSB, the parasitoid Trissolcus japonicus.


Classical biological control of invasive insect pests

Mark Hoddle

Biography: Mark Hoddle has worked as an extension specialist in biological control in the Department of Entomology at the University of California Riverside for 22 years. Projects have targeted invasive insect and mite pests of avocados, grapes, citrus, native California oaks, and dates. Notable accomplishments have been the successful CBC of the glassy-winged sharpshooter, Homalodisca vitripennis (Hemiptera: Cicadellidae) in French Polynesia, cottony cushion scale, Icerya purchasi (Hemiptera: Monophlebidae) in the Galapagos Islands, and Asian citrus psyllid in California. Hoddle has a MSc and DSc in Zoology from the University of Auckland, New Zealand, and Ph.D. in Entomology from the University of Massachusetts, Amherst in the USA.


Development and implementation of biocontrol-based integrated pest management in Africa - Challenges and opportunities

Sevgan Subramanian 

Biography: Dr. Subramanian has worked for 12 years as a Senior Scientist with icipe, Nairobi, Kenya. Most of his research focus has been on understanding the biology of key pests such Western Flower thrips, Diamondback moth and more recently Fall armyworm and their natural regulatory factors for development of IPM strategies for their management. Dr. Subramanian has a Post-doc in insect ecology from icipe. He obtained his MSc and PhD in Agricultural entomology from Tamil Nadu Agricultural University, India, investigating the use of baculoviruses for management of key lepidopteran pests of cruciferous vegetables.

Recently, Dr. Subramanian was recently promoted as Principal Scientist and Head of the Arthropod Pathology Unit at icipe. He also assumed the lead on Fall armyworm IPM project funded by the European Union, which focuses on building resilient maize production systems in east Africa to counter the pest, expanding conservation/classical biological control and development of biopesticides and biorationals.
