What is Entomology?

Insects 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. 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. 

Our Department's work focuses on ways to:

  • understand the impact insects have for pollination, biological control, and other beneficial services as well as contributing to environmental biodiversity
  • understand the impact insects have on the sustainable production of our vitally important corn, soybean and wheat industries in Ohio;
  • understand the impact insects have on the growing and emerging industries of fruit, vegetable, horticultural and specialty crop production, which increases the availability of nutritious foods and food security
  • understand the impact insects have on disease transmission and the health of animals and humans;
  • understand the impact insects  have on healthy soils and agricultural production across urban and rural communities, and
  • understand the impact insects have on food systems and how these can be transformed for better resiliency and sustainability
We invite you to explore, learn, study and research with us!
