An Introduction to the Characteristics, Habits, and Farming Value of Mealworms

Mealworm is the common name for the larvae of the yellow mealworm beetle, an insect of the order Coleoptera, family Tenebrionidae, named for its frequent use as bird feed. The body is long and cylindrical, yellowish-brown in color, with a rather hard body wall and slow movement, making it one of the common farmed insects.

A mealworm goes through four life stages: egg, larva, pupa, and adult, among which the larval stage is the longest and is also the main stage used in farming. It prefers a warm, dry environment, fears strong light, and has a gregarious habit; when density is too high or feed is insufficient, cannibalism occurs, so farming requires attention to grouping and timely feeding.

In terms of application value, mealworms have a high protein content and contain a variety of amino acids, making them a favorite live feed for ornamental birds, turtles, lizards, fish, and poultry, and they can also be dried and processed into dried worms or worm meal. They eat a wide range of foods, reproduce quickly, and have low site requirements, and are considered a promising source of insect protein.

In farming, mealworms feed mainly on wheat bran, rice bran, and the like, supplemented with vegetable leaves and melon and fruit peels for moisture, and management is relatively simple. Daily care requires attention to temperature control and ventilation, avoiding direct sunlight, and guarding against mites, ants, rats, and other pests. Once the larvae reach a suitable size, they can be harvested for feeding; for detailed procedures, refer to the article on farming methods on this site.
