Two faculty members in Penn State's College of Agricultural Sciences will be featured during an episode of the PBS series "Nature" that will air in most markets at 8 p.m. on April 3. Titled "What Plants Talk About," the episode will highlight the work of Consuelo De Moraes, professor of entomology, and Mark Mescher, assistant professor of entomology. The researchers are engaged in the growing field of chemical ecology, which examines the chemically mediated interactions among plants, insects and pathogens in the environment.
