What should I do if silkworms do not grow?
In the production of sericulture, silkworm silkworms do not produce pods in the production of sericulture, causing some loss to sericulture production. First of all, we must find out the reason why silkworms do not produce scars, and then take measures to prevent them. The main reasons are: 1. Pathological factors. For example, pyogenic disease and softening disease affect the onset of infection in the upper eyelid, which destroys the silk gland's secretory function; or pathogens produce a large number of toxic metabolites in the silkworm body, making the silkworm's nerves paralyzed and unable to lay down. 2. Physiological factors. The abnormal silk glands in the middle part of the country are mainly due to the high feeding temperature, excessive tender leaves, abnormal secretion of glandular glands, and other abnormal silk glands. Followed by anomalies of the anterior silk glands, it is mainly due to contact with a large number of gas, fish helium, alcohol and other undesirable gases that cause silking disorders during the feeding process. 3. Trace pesticide poisoning. During feeding or feeding, the silkworm eats or touches trace amounts of pesticides causing silkworm glands to be disordered in the body, but not silking. 4. The operation was inappropriate. The silk glands are ruptured or the temperature is too low, so that the silkworms can stop spinning for a long time. When the upper jaws are too dense, the silkworms cannot find the scars, or the cookers are not dry, and the environmental conditions of the upper jaw are not easy to cause silky scarring. Happening. Control methods: 1. Prevent silkworm diseases and strengthen management. Strictly sterilize, eliminate pathogens, cut off the infection route, and do a good job of disinfection around the silkworm, silkworm, and silkworm. Can be used bleach solution containing 1% of available chlorine or 1% to 2% fresh lime water spray disinfection; strengthen feeding and management, enhance silkworm body resistance. Selecting silkworm strains with strong disease resistance to avoid the influence of summer and autumn hot weather on the silkworm sheds, keeping the silkworm houses suitable for temperature and humidity, fresh air and clean silkworms; adding chloramphenicol to the silkworms at the age of 1 or 2 times per year. Each cc should contain 500 units of chloramphenicol. 2. Prevent pesticide trace poisoning. The mulberry leaves that have been contaminated with pesticides should be prevented from being fed; and the silkworms, silkworms, and sericulture supplies should be protected from pesticide contamination. The silkworms do not stack pesticides, silkworms do not contain pesticides, and sericulture supplies do not contact pesticides. 3. The operation must be detailed. When you are on the squat, you have to do "three straights" and "three drys." Sanyun is mature and well-proportioned, and is not partial to life; the density of the upper jaw is even and not dense; the upper jaw is uniform and old, not old. The third drying is the bedroom cooker and the environment is dry.
