A new study published in the Journal of Insects as Food and Feed has revealed that yellow mealworms can serve as an alternative protein source for animals and, possibly, humans. The study comes at a time when global food demands keep rising. Spontaneous population growth in developing countries has led to a shortage of protein sources, prompting researchers to look for alternative options. The new research, conducted by Indiana University–Purdue University Indianapolis (IUPUI), proposes yellow mealworms as a food source.

Christine Picard, associate professor of biology and the director of the Forensic Investigative Sciences Program at IUPUI School of Science, led the research. The study focused on analyzing the genome of a mealworm species known as tenebrio molitor.

“Human populations are continuing to increase, and the stress on protein production is increasing at an unsustainable rate, not even considering climate change,” Picard said.

Findings explain that the yellow mealworm can offer several agricultural benefits. Fish and domestic birds can use the worms as an alternative source of protein. The worms can also help produce organic fertilizer, with their nutrient-rich waste.

The mealworm genome research employed a 10X Chromium linked-read technology. Researchers now say that this information is available for use by those seeking to utilize DNA to optimize mealworms for mass production. According to Picard, IUPUI’s research has dealt with the challenging part, opening doors for interested stakeholders.

Insect genomes are challenging, and the longer sequence of DNA you can generate, the better genome you can assemble. Mealworms, being insects, are a part of the natural diet of many organisms,” Picard said.

Since fish enjoy mealworms as food, the researchers propose adopting these worms for fish farming. Researchers also say that pet food industries can use the worms as a supplemental protein source. In the future, mealworms could also serve as food for humans.

“Fish enjoy mealworms, for example. They could also be really useful in the pet food industry as an alternative protein source, chickens like insects — and maybe one day humans, too, because it’s an alternative source of protein,” Picard said.

To facilitate the yellow mealworm’s commercialization, the IUPUI team continues researching the worm’s biological processes.
