Feeding management of ramie silkworm

Ramie is a resource insect that gets its name because of eating ramie leaves. The pods are pod-shaped, with holes at the top and white in color. They are a good raw material for silk spinning. Feeding ramie silkworms has many advantages: First, it can be combined with ramie seedlings to promote the production of castor beans; Second, ramie silkworms can also eat cassava, odor, in addition to eating ramie leaves. Such as leaves, rich in feed; Third, ramie silkworm feeding time is short, from hatching to scab, as long as about 18 days, 1 year can be continuously fed many times; Fourth, ramie silkworm needs a little feed for life, every silkworm life Only eat less than 5 grams of nettle leaves; Fifth, the living ability of ramie silkworm is strong, not easy to get sick, and management is relatively simple. Therefore, ramie silkworms can be raised in accordance with local conditions. The feeding and management methods of ramie silkworms are generally the same as those of silkworms. However, in the feeding and management process, special attention should be paid to the following points: (a) To control the temperature of the hatching eggs of the ramie silkworm, fearing dry and stuffy heat, hatching the silkworm at 22--28°C is most suitable. If the temperature is too high, cool down. A simple way to cool down is to put silkworm eggs into the cocoon and hang them in the middle of the well with a rope. If there are no wells, cool water can be placed in the large vat, and the larvae of the silkworm eggs will be placed on top of the cold water in the tank, and the water will be frequently changed to keep the temperature in the vats appropriate. (b) For feeds such as ramie leaves, the storage time should not exceed 1 day for storage if required. It is better to spend the evening in the evening. For harvested castor leaves, etc., can be stored in the empty cylinder, leaving a gap in the middle of the cylinder, the leaves covered with a damp cloth. The amount of leaf collected should be determined according to the amount of leaves needed on the previous day. Do not harvest too much at one time. The amount of leaves that can be eaten on the same day will cause aging of castor leaves. (C) size of ramie silkworm to distinguish between feeding in the feeding of small silkworm, ramie leaves should be torn small, big silkworm can be used when feeding big leaves. Starting from the second instar silkworm, the silkworm excrement must be removed regularly. The method of clearing the silkworm excrement cannot be directly used to catch the silkworm by hand. The silkworm should be led to a new leaf, and then the leaf ribbon can be lifted after being lifted up. As the body weight of large silkworms increases rapidly, they should be reared separately in time to prevent crowding and affect normal growth. (D) to be prepared in advance to do the bigger leaves of ramie silkworm do quail, generally in the Indus, poplar and other larger leaves. Therefore, before the ramie silkworm is used as a cricket, it is necessary to prepare enough larger leaves so that the ramie silkworm can be licked and easily peeled off. (5) When silkworm cocoons that have kept seeding and taking silkworm silkworms are removed in time from the leaves, except for the remaining seed cockroaches, the rest of the cockroaches shall be quickly sold, dried, and killed for cocooning. . About 18 days after the scab, the clams become moths, and they bite into the cocoon to copulate and spawn. For extra species, cut a small mouth immediately on the oyster shell and remove the silkworm cocoon. These cocoons can either be cooked or fried and served as food for livestock and poultry. Although the life of ramie silkworm is short, it also passes through four sleeps and five instars. Its eggs have no diapause, and their growth and development do not stop for many years. Some species of ramie silkworms have been artificially domesticated and are now able to survive in winter in China.
