Insects as food and feed: research and innovation drive growing field

September 11, 2019

Annapolis, MD; September 11, 2019--As the global food supply faces the dual challenge of climate change and a growing human population, innovative minds are turning to a novel source for potential solutions: insects.

While insects are commonly understood in their roles as either pests or pollinators in agricultural settings, a burgeoning movement in both research and industry circles is looking to insects as a food source themselves, both for human consumption and as feed for livestock. A new special issue of the Annals of the Entomological Society of America, published today, showcases a collection of the latest research on insect agriculture for food and feed.

Globally, the use of insects as food and feed is far more common than it is in North America, where insect agriculture evolves around just a few species: crickets Acheta domesticus and Gryllodes sigillatus, mealworms (Tenebrio molitor), and black soldier flies (Hermetia illucens). Yet, more than 1 million insect species are known to science--a clear indication of the room for growth in the field.

Jeffery Tomberlin, Ph.D., professor of entomology at Texas A&M University, specializes in the study of black soldier flies and served as co-lead editor for the special collection in Annals of the ESA, alongside Valerie Stull, Ph.D., a postdoctoral research associate at the University of Wisconsin-Madison's Global Health Institute and co-founder of the collaborative MIGHTi (Mission to Improve Global Health Through Insects) Project.

"I am thrilled to see the development of this new sector in agriculture," Tomberlin says. "While the industry is less than 20 years old as related to mass production, its value is expected to exceed $8 billion within the next few years. In fact, I would not be surprised to see the industry increase in value beyond $50-100 billion by 2050. I truly believe this industry will not only bolster the global ag sector but also protect the environment while creating jobs and saving lives."

The special collection in Annals of the ESA highlights the active and diverse research avenues in which insects as food and feed--or, entomophagy--is now being explored and where it will likely continue as the movement continues to grow, such as the cultural and economic aspects of human consumption of insects as food, health implications of insect consumption, optimization and industrialization of insect agriculture, and identification and biological knowledge of insect species suitable for farming.

Articles in the collection include:
  • A Special Issue on Insects as Feed and Food as Tribute to Dr. Marianne Clopton Shockley (14 August 1975 to 12 March 2019)
  • Eating Insects Athens Conference 2018 and the North American Coalition for Insect Agriculture

  • The Colonial/Imperial History of Insect Food Avoidance in the United States
  • The Need for Alternative Insect Protein in Africa

What makes breakfast, breakfast? Well, according to every movie and TV show we've ever seen, a big glass of orange juice is basically required. But our morning grapefruit might be in danger. Why? Citrus greening, a bacteria carried by a bug, has infected 90% of the citrus groves in Florida. It's coming for your OJ. We'll talk with University of Maryland plant virologist Anne Simon about ways to stop the citrus killer, and with science writer and journalist Maryn McKenna about why throwing antibiotics at the problem is probably not the solution.
