In this presentation I will briefly review the founding of Cornell Entomology by John Henry Comstock and describe the scientific and teaching environment that Comstock catalyzed and which remains to this day. Within this context, significant research accomplishments include: the development of chemical ecology and its application; development of the ecological theory as well as specific tools for biorational insect control; continued development and curation of a vast insect collection and providing leadership for drafts of the International Code of Zoological Nomenclature; development of ecological and genetic understanding that provided a basis for insecticide resistance management. Significant extension accomplishments include: codification of IPM tactics that could be easily adopted by practitioners; application of systematic and taxonomic resources towards the detection of invasive species; development of an online curriculum for beekeepers. Significant teaching accomplishments include: A graduate program that spans several departments and institutes, that allows for maximum flexibility among students, and has been a leader in education and placing entomologists throughout the world.
