As the global population grows, so does the demand for animal protein, placing increasing pressure on livestock systems to produce more with fewer natural resources. This challenge has led researchers and agricultural scientists to seek alternative, more sustainable protein sources

Insects need to replace the old cuticle with a new cuticle to metamorphose and mature. The cuticle is the outermost component of insects that covers all the external parts of the body of invertebrates. It is also present in small amounts in some internal parts of the body of insects.

About 80% of the 1,600,000 animal species have been identified, belong to Arthropoda phylum. The group of insects in the Arthropoda phylum are the most diverse and populated.

The larvae of the bark beetle are called Mealworms having their high nutritional value and are suitable feed for aquatic, animals and poultry. In this part, we will describe the life cycle and the uses of mealworms

Mealworms, the larval stage of darkling beetles (Tenebrio molitor), have gained attention as a potential ingredient in aquatic animal nutrition due to their high nutritional value and sustainability. While primarily known as a feed source for terrestrial animals, mealworms offer several benefits when incorporated into aquatic diets.

The mealworm (Tenebrio molitor) is the larval stage of the darkling beetle. It is a common insect used in various applications, including animal feed, pet food, and human consumption.

Mealworms prefer dark environments due to their natural behavior and ecological adaptations. There are a few reasons why they are more comfortable and thrive in darkness:

Mealworms (Tenebrio molitor) have gained attention as a potential food source for humans due to their nutritional properties. Here are some of the properties of mealworms for humans:
