How to raise silkworm pupa

Silkworms become silkworm pupae after spinning and cocooning, and many people are at a loss in the face of silkworm pupae and do not know what to do with them. So how to raise silkworm chrysalis?

1. How to raise silkworm pupae

Prepare the silkworm room, silkworm tools and mulberry leaves, and thoroughly disinfect the silkworm tools and silkworm rooms. In spring and summer, pour silkworm eggs on paper to collect ants and silkworms, and then feed 2-3 meals of fresh leaflets every day to control the temperature at about 27 degrees. To grow to 2 years old, properly reduce the temperature, feed 2-3 meals of mulberry leaves every day, do a good job in water and disease management. When the silkworm reaches the fourth instar, the silkworm begins to cocoon and gets its pupa after peeling it off.

Does the silkworm moth need to be fed

The silkworm moth does not need to be fed. After emerging from its cocoon, the female moth will lure the male moth to mate through the smell from its tail. The male moth dies immediately after mating. After mating, the female moth chooses a place to lay about 500 eggs and then dies slowly.

3. Discrimination and preservation of silkworm eggs

There are three situations in which silkworm moths lay eggs.

The eggs that turn brown or darker in two or three days are the diapause eggs that come out next year; they do not change color for a few days, or they turn pink and turn red on the 8th, followed by non-diapause eggs; the eggs that do not change color all the time, and then dry up are the unfertilized eggs, that is, dead eggs.

The preservation of diapause eggs can be divided into room temperature preservation and cold storage. The method of cold storage is to refrigerate the silkworm eggs in a refrigerator of 5 degrees Celsius after confirming that the eggs have become dark and diapause 10 days after spawning. It should be noted that silkworm eggs should be kept dry without water droplets, and should not be placed in a refrigerated position to prevent freezing.

Silkworm pupae do not need to be reared, just rest in one place after cocooning, and the adults will come out on their own after turning into moths and follow their instincts to give birth. Friends who raise silkworms must wait patiently.
