Large, predaceous wasps as potential pest control agents will be discussed by Dr. Joe Coelho is an Associate Professor of Biology at Quincy University, where he teaches courses in ecology, environmental science, zoology, botany and other topics. Both an educator and a scientist, he earned a Bachelor of Science degree from the University of California, Riverside in 1984 and a Ph.D. from the University of Colorado in 1989. While he has authored papers on cultural entomology, most of his research focuses on the ecology and evolution of wasps. Known as a mad scientist and adventurer, Coelho is also an award-winning outdoor writer and photographer. Coelho combines an understanding of natural history with a passion for photography in his public speeches.
Predaceous wasps are seldom considered among methods of biological control. However, several common species are caterpillar specialists and have the potential to reduce a variety of garden and orchard pests. Two types of wasps will be highlighted in this slide/lecture presentation. The carpenter wasp, Monobia quadridens, is a widespread, solitary wasp that preys mostly on pyralid larvae. It has a long season and is easily cultivated. Paper wasps (Polistes spp.), though more aggressive, are generalists on a wider range of prey. A social species, they are also easy to encourage in desired areas. Advantages and disadvantages of each type, as well as means of boosting their numbers, will be described.

Dr. Joel Gruver discovered his fascination with crops and soils at a young age on his family's homestead in rural Maryland. His formal education includes a BS in Chemistry from Principia College (Elsah, IL), an MS in Agronomy from the University of Maryland (College Park, MD) and a PhD in Soil Science from North Carolina State University (Raleigh, NC). He has taught courses related to soil science and agroecology at Tufts University, Principia College, North Carolina State University, Central Carolina Community College and Western Illinois University where he is currently an assistant professor and director of the WIU Organic research program. Joel is a continuous student of the art and science of soil management and enjoys helping farmers and gardeners to translate scientific concepts into practical applications.
