Insect Feed Could Be the Next Frontier in Animal Agriculture

My latest piece for Earth Island Journal is about how insect feed could be the next frontier in animal agriculture. I focus on the research — and breakthroughs — of scientist Philip Taylor, who is examining the role the black soldier fly can play as an alternative protein source in livestock feed. Read an excerpt below:

Insect Feed Could Be the Next Frontier in Animal Agriculture

Bugs offer an environmentally friendly alternative to soy and fishmeal when it comes to feeding livestock

By Sena Christian

Philip Taylor knew that when the black soldier fly began mating under artificial light in his hatchery at the Institute of Arctic and Alpine Research in Boulder, Colorado, something important was happening.

“For the mass production of larvae there needs to be a large and consistent source of eggs,” he explains. Taylor, a fellow with Duke University and INSTARR, needs a lot of larvae for his investigation into how insects can be used as an alternative protein source in animal feed. Using ultraviolet light, humidity and temperature, Taylor is trying to influence mating and egg production among the black solider fly. The goal is to mimic the subtropical and warmer temperate climates where these flies naturally occur, and Taylor is confident he’s found the light bulb that provides just the right balance. He says he’s already achieved about an 80 percent reproduction rate, which is the highest he knows of under artificial conditions.

The motivation for Taylor’s research stems from his belief that insects can be the cornerstone of a new-and-improved food system. He’s not alone in touting this great source of protein; putting edible insects on the menu has garnered plenty of media attention recently. Feasting on these healthy little buggers could help feed a growing global population projected to reach nearly 10 billion by 2050 and reduce the environmental impact of eating meat. But if chowing down insects isn’t your cultural norm, the option might sound kind of gross. Maybe one day most Americans will get there. But, in the meantime, why not use insects as a protein source in animal feed to replace fishmeal and soy?
