Hello, dear. Silkworms spit green water because they have indigestion, which causes food to not be fully absorbed in the intestines, producing a kind of green feces called "green dung", which is an abnormal phenomenon caused by burning repentance. Silkworm spitting green water is usually caused by the following frank traces of several reasons:

1.Silkworms have eaten unsuitable mulberry leaves, such as contamination with chemical fertilizers, pesticides or other harmful substances. 2.

Silkworm tofu is too soft or not nutritious, which can also easily cause silkworms to spit green water. 3.Poor environment of silkworms, such as too high or too low temperature, too high or too low humidity, etc., will affect the health of silkworms.

2.Reasonable preparation of tofu feed to ensure that silkworm tofu is nutritious. 3.

Create a suitable silkworm breeding environment and maintain a balance of temperature, humidity and other factors. 4.After the silkworm spits green water, it can be given a certain amount of rest time, and adjust the feeding and environmental conditions, so that the silkworm can adapt to the environment and food and restore health.

In short, for the feeding management of silkworms, it is necessary to comprehensively consider many factors such as feeding environment and feed, so as to ensure the healthy growth of silkworms and improve the industrial benefits of silkworms.

Spitting green water is because silkworms have eaten poisonous mulberry leaves or stayed in a toxic environment, which is a manifestation of poisoning. Before feeding mulberry leaves, it is necessary to soak them in water, or soak them in ozone water, and wipe the water droplets on the surface before feeding, which can effectively avoid silkworm diarrhea. <

Silkworm Egg: Silkworm reproduces with eggs. The silkworm eggs look like fine sesame seeds, about 1 mm wide and about mm thick.

A female moth can lay 400 500 silkworm eggs. 1700 2000 silkworm eggs weigh about 1 gram and are in diameter. The color of silkworm eggs is pale yellow or yellow when it is first laid, and it becomes pale red bean color and red bean color after 1 2 days, and then turns gray-green or purple after 3 or 4 days, and then it no longer changes, which is called fixed color.

The outer layer of the silkworm egg is a hard egg shell, and the inside is the yolk and serous membrane, and the embryo in the fertilized egg continuously ingests nutrients during the development process, and gradually develops into an ant silkworm, which crawls out of the egg shell, and the egg shell becomes white or light yellow after the egg shell is empty.

The silkworm turned yellow and died.

When the silkworm is small, it is gray. When the silkworm hatches from the silkworm egg, the color of the body is brown or black, very small, and there are many fine hairs, and it looks a bit like an ant, so it is called ant silkworm. The ant silkworm is about 2 mm long and about 2 mm wide, and after crawling out of the shell of the reed source of the egg cavity, it will eat mulberry leaves after 2 to 3 hours.

As the silkworm grows up, it becomes white with small black dots. When the silkworm baby reaches the end of the fifth instar, it gradually shows the special wisdom of maturity: first, the excreted feces change from hard to soft, from dark green to leaf green; loss of appetite and decreased amount of mulberry eaten; The anterior digestive canal is empty, and the thorax is hyaline; Then stop eating completely, the body drive is shortened, the abdomen also tends to be transparent, the cephalothorax of the silkworm body is raised, the mouth is spit silk, and the left and right swing up and down to find a place to camp in the cocoon, such a silkworm is called a mature silkworm.

When the silkworm first died, it was the same as when it was alive, that is, it was soft when it was held in the hand, and there was no reaction. After a few days it turns yellow.

Many silkworm farmers have encountered silkworms spitting green water, which is actually a manifestation of silkworm poisoning. In this case, it is best to isolate it from several others, so as not to infect, silkworm poisoning is likely to be because the silkworm eats the leaves with pesticides, it is usually best to wash the leaves and then dry them with a clean cloth, and then feed, so that the pesticides can be cleaned, and the silkworms can effectively avoid diarrhea. After picking the leaves eaten by silkworms, you can put the leaves in a plastic bag and put them in the refrigerator, take them out before feeding them to return to normal temperature, and then feed them to eat.

The living environment is also very important for the growth of silkworms, 1-2 years old silkworms suitable temperature 26 27, relative humidity 90%, need to cover and pad plastic film. The same is true for the suitable temperature of the 3rd instar silkworm, the relative humidity is required to be 85%, and only the plastic film is covered at this time. 4-5 years old silkworms, suitable temperature 25, silkworms to high temperature and humidity, carbon dioxide resistance is weak, can be used indoor ground breeding and outdoor scaffolding breeding.
