How do barley worms reproduce

Barley insects were introduced from Southeast Asian countries in recent years. The maximum body length of mature larvae is about 7 cm, which is 3-4 times larger than that of common yellow powder insects. The yield is 5 times that of yellow powder insects, and its nutritional value is far higher than that of young crickets and yellow powder insects. So how do barley worms reproduce?

How do barley worms reproduce

Barley worms usually begin to mate and lay eggs about ten days after emergence. ? Each female lays at least 300 eggs. Barley worms should properly add green material and concentrate to the adults after each egg collection to clean up the dead adults in the waste in time.

2. Introduction of each stage of barley worm

1. Egg

The eggs of barley worms are oblong and milky white, about 1.5 × 2 mm long and 0.6 mm wide. The appearance of the egg is the egg shell, the egg shell is thin and soft, and is very vulnerable to damage. There is mucus on the outside, which can adhere to a layer of insect dung and feed, which plays a protective role. The egg period is 7 to 10 days.

two。 Larva

The barley worm is large, and the larvae are generally 40-60 mm in length and 5-6 mm in width. The single worm weighs 1.3-1.5 grams and is cylindrical. Its body wall is hard, yellowish brown, glossy, with 13 nodes, with yellowish brown ring at the joint and yellow ventral surface. In the process of larval growth, the body surface color is white at first. The skin became yellowish brown after the first molting, and then molted once every 4-6 days, and a total of 6-10 times in the larval stage. The growth period is 60 days. The larvae began to molt from the beginning, and the pre-molting activity began to decrease. The newly molted larvae were milky white and very fragile. The most vulnerable.

3. Pupa

Barley insects have stronger habits of killing and feeding each other than yellow pink worms. Pupating larvae are as often injured as molting larvae, and larvae sometimes bite pupae, making barley worms give up pupation and survive as larvae for a long time and cannot peel and change pupae to lay eggs.

4. Adult worm

The adult stage of barley worm is the breeding period of barley worm. The adult has just molted its shell milky white, the head is orange, the carapace is very thin, the back becomes dark brown after 1-2 days, and the abdomen is yellowish brown and oval, about 25-30 mm long and 8 mm wide. The body of the worm is divided into three parts: head, chest and abdomen, with 3 pairs of feet.

Barley insect is a fully abnormal insect, which has to experience four states of egg, larva, pupa and adult in its lifetime, and the whole life cycle is 6 months or longer.
