Our guest is Dr. Mark Hoddle, Distinguished Professor of Extension in Biological Control at the University of California - Riverside, a renowned expert in the field of biological control of invasive insect pests. He presents the checkered history of efforts to find organisms that target damaging invasive species, including some early efforts that succeeded and some that backfired. His work is grounded in that history and follows a rigorous and demanding process to identify such organisms. A major part of his work is understanding the mechanisms limiting predation or infection to target species, so a biological agent can be released without harming non-target species. Join us for a fascinating look at the intersection of hard science and agriculture.
