MS’10 • Patrick “PJ” Liesch—better known as Wisconsin’s “bug guy”—received his master’s degree in entomology from CALS in 2010 and worked as a research associate on campus. After Phil Pellitteri, the legendary king of insect diagnostics, retired in 2014, Liesch took on the position. As director of the UW–Madison Insect Diagnostic Lab, Liesch completes a variety of duties including communicating insect information to the public and acting as a bug identification guru to curious residents and businesses from all over Wisconsin. Liesch estimates that he tackles more than 2,000 cases per year. Liesch also serves as an instructor with the Wisconsin Master Gardener Program and the Wisconsin Pesticide Applicator Training program as well as with Farm and Industry Short Course. As part of his public outreach work, Liesch is a regular guest on Wisconsin Public Radio’s Larry Meiller Show.
