A study on the living habits of mealworms

<> living environment of the yellow powder stove nucleus is relatively dark and dry. Mealworms like dry rather than wet, do not like light, suitable for living in a dim environment, adults encounter strong light, will go to the dark place hidden orange to escape, although day and night can be active, but nocturnal activity is more active.

The adults are white, yellowish-brown, black-brown, brownish brown on the ventral surface and the dorsal surface of the elytra, shiny, oval, 14 15 mm long and about 6 mm wide. The body of the worm is divided into three parts: head, thorax and abdomen. Adults have black elytra with obvious longitudinal stripes on the back of the elytra, and the elytra cover the hind wings when at rest, and the hind wings are membranous with winged veins, folded vertically and horizontally under the elytra, and the male has a cohesive device hidden in them.

1. Morphological characteristics: the newly emerged adult is white, gradient yellowish-brown, black-brown, the ventral surface and the back of the elytra are brown, shiny, oval, 14 15 mm long and about 6 mm wide. The body of the worm is divided into three parts: head, thorax and abdomen.

Adults have black elytra forewings, the back of the elytra has obvious longitudinal stripes, the elytra cover the hindwings when stationary, the hindwings are membranous with wing veins, folded vertically and horizontally under the elytra, and the male has a handover sharpener hidden in it.

2. Life habits: The larvae of mealworms like to swarm, 13 on active feeding, more than 35 can still grow, more than 50 can not survive, there is a large bite between the larvae and the adult, and they will kill each other when they lack food, and the larvae sometimes bite the pupae.

3. Distribution: Its footbook traces are almost all over the world. In China, it is mainly distributed in Heilongjiang, Liaoning, Shanxi, Shandong and other provinces. At present, mealworms in captivity are found in almost every province (region).

Mealworms, also known as breadworms, belong to the order Coleoptera in insect taxonomy, the family of walking insects, the genus of mealworms is the genus of walking insects, native to North America, and were introduced into China in the fifties from the Suzhou Sale.

Dried mealworm products contain 30% fat, up to 50% protein, and also contain phosphorus, potassium, iron, sodium, aluminum and other macroelements and a variety of trace elements. Because the dried mealworm larvae contain about 4% protein, the pupa contains 57%, and the adults contain 60%, it is known as the "treasure trove of protein feed".

The suitable temperature for mealworm larval activity is 13 to 30 degrees, and the optimal temperature is 25 to 29 degrees. Mealworms at zero degrees.
