How to raise silkworm eggs

Silkworm eggs are what we call silkworm eggs. Many sericulture friends will harvest a bunch of silkworm eggs in the first year, but they don't know how to hatch young silkworms. Today, let's learn how to raise silkworms.

First, how to raise silkworm eggs

Spread the silkworm eggs in a clean, tasteless box and put them in a house with a constant temperature of about 25 ℃. In about 14 days, the silkworms turn black and the young silkworms will come out.

Second, how to take care of silkworms after hatching

Silkworms that have just hatched from their eggs are called ant silkworms because they are black and covered with fine hair, like ants. But their fine hairs will be gone in a few days. The silkworm ants can be fed about 40 minutes after they come out of the shell, so we should prepare the food in advance and choose the tender leaves of mulberry leaves that are pesticide-free, clean and water-free.

Third, how to distinguish silkworm eggs

After the silkworm moth lays eggs, we can tell whether it is a dead egg by observation. There are three situations. 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.

4. How to preserve silkworm eggs

The eggs laid by silkworm moths do not want to hatch and the young silkworms do not want to be discarded. How can they be preserved? We can keep it in cold storage. The method of cold storage of diapause eggs is that 10 days after the silkworm moth lays eggs, after confirming that the eggs have become dark and diapause, the eggs are refrigerated in a refrigerator of 5 ℃. 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.

The hatching of silkworm eggs is relatively simple, we can carry out in the warm beginning of spring, sericulture must supply sufficient mulberry leaves, so that silkworms grow well and quickly.
