Scientists from the International Centre of Insect Physiology and Ecology have found that the larvae of the Kenyan lesser mealworm can chew through polystyrene.

About Mealworm Larvae:

  • The lesser mealworm is the larval form of the Alphitobius darkling beetle. The larval period lasts between 8 and 10 weeks.
  • The lesser mealworms are mostly found in poultry rearing houses which are warm and can offer a constant food supply — ideal conditions for them to grow and reproduce.
  • Distribution: These are thought to have originated in Africa, they can be found in many countries around the world.
  • Mealworm larvae are capable of consuming polystyrene
  • The bacteria living in the mealworms' gut help them break down the complex polymers in plastic. 
  • These bacteria produce enzymes capable of digesting the plastic.

What is polystyrene?

  • It is known as
  • Applications: It is a plastic material that’s widely used in food, electronic and industrial packaging.
