What is Entomology?


Insect species outnumber all other life forms combined. Although less than 5% are pests, they consume about 20% of the world's crops. Throughout history, insects have killed more people than war.  Fortunately, many more species of insects are beneficial, helping to control pests and recycle nutrients.  Without pollination by honey bees and other insects, our diet would have few fruits and vegetables.  

We truly live on a planet of insects! 

The Department of Entomology at The Ohio State University is the only university department in Ohio focused on the study of insects.  We address the Land Grant missions of teaching, research, and extension with programs focused on:

  • management of insect pests of crops and gardens;
  • beneficial roles of insects as biocontrol agents and pollinators including honey bee health; 

  • effects of climate change on pest dynamics;

  • urban agriculture and local food systems; 

  • invasive forest pests including emerald ash borer and Asian longhorned beetle;

  • household and structural pests such as termites and cockroaches; and 

  • impacts of insects on human and animal health including disease-vectoring mosquitos, Lyme disease, and bed bugs. 

We use insects as model systems to further fundamental understanding of molecular biology, physiology, genetics, ecology, and evolution.  We provide instruction at the undergraduate (major and minor) and graduate levels (M.S. and Ph.D).  Our extension and outreach programs provide non-biased, research-based information to stakeholders to help protect crops, natural resources, structures, and human and animal health. 

We invite you to explore, learn, study and research with us!
