There are more than 1 million species of insects found in the world, which is the largest and largest group in the animal kingdom, and has a significant impact on agricultural production and human health. The 6 kinds of small insects related to agriculture introduced to you today are good helpers for farmers in agricultural production and life.
01
Horned aphid
The "five-fold seed" is a gall formed by the parasitization of the horned aphid on the salt-skinned wood.
Horned aphid is a kind of insect of the aphid family, mainly produced in China, with astringent hemostasis, lung cough, astringent intestines and diarrhea, sweating, detoxification and other functions. Indications for the treatment of lung deficiency cough, prolonged diarrhea and prolapse, sweating, blood, blood production, spermatozoa, enuresis, sores, heavy metal salts and alkaloid poisoning, etc.; external treatment of burns, prolapse, hemorrhoids, cervical erosion, lymph node tuberculosis, stomatitis, gingivitis and so on. It is also an important raw material and reagent for dyes, tanning, chemical, petroleum, smelting and other industries.
When artificial breeding, it is best to make the juvenile aphids grow a layer of white wax powder in the container (usually 7-10 days), and then put it on the winter host, so that inoculation and introduction are more likely to succeed.
02
Castor silkworm
It is one of the important silkworm species for silk production, likes to eat castor leaves, simple to raise, rapid growth, and can be raised all year round in southern China. The properties of silk are basically similar to those of silkworms, and they are elastic, and after combing, 60.9% of the long fibers of 1 to 4 grades, 35.3% of the short fibers, and only 3.8% of the losses. Silk is acid and alkali resistant, has good moisture absorption, and after cocoon refining, it has become an excellent industrial raw material for silk spinning.
The feeding and management method of castor silkworm is generally the same as that of mulberry silkworm. However, in the process of breeding management, special attention should be paid to the following points:
It is necessary to control the temperature of incubation, feed such as castor leaves should be fed with picking, large and small castor silkworms should be raised differently, and large and large leaves should be prepared in advance to make cocoons, and timely do a good job of seed retention and pupae.
03
Camphor silkworm
Camphor silkworm is a wild spitting insect, also known as maple silkworm. Its silk can be made into silkworm intestinal thread (wound suture) and high-quality fishing silk, so it is called fishing silkworm. China is more common in Guangdong, Taiwan, Guangxi, Fujian, Jiangxi, Hunan and other places. There are many kinds of plants that eat leaves by camphor, mainly camphor trees, maple trees, cabinet willows, wild roses, sand pears, guavas, purple shell wood and ke trees, etc. Those who eat camphor leaves have the best silk quality, and those who eat maple leaves have poor silk quality.
04
Ash worms
Ash worm is an insect of great economic value. Ash worms parasitize on the host plant, males secrete wax, females breed offspring, and males secrete wax called ash.
White ash can promote wound healing, can make plasters and Polishing Agents for Chinese and Western Medicine Sugar-coated Tablets, and can be used as a pill shell for a long time. Modern medicine uses white wax to treat tracheitis, which has a certain curative effect. It can also be applied to exploratory treatment of stomach cancer.
In the industrial aspect, it can be used for various precision machinery and metal utensils for moisture, rust and lubricants, and is also a raw material for the manufacture of automotive wax, floor wax, valuable furniture and other products.
In addition, ash worm female worm is also a nutrient-rich biological resources, female worm rich in protein, amino acids, unsaturated fatty acids, trace elements, vitamins, lecithin, brain phospholipids, polysaccharides, chitin, flavonoids and other substances, with high nutritional and health value.
When stocking ash worms, choose a place where wax trees or Privet trees are concentrated, cut off old leaves and dead branches, wrap the insect species with brown flakes or sun-dried tung leaves, each pack of 5-6 insect species, choose sunny or cloudy days, and hang the seed insect bag 10 cm from the branch (or 3 cm from the branch) on the leeward side of the tree. After 1 month, when all the larvae crawl out, the seed insects should be removed in time to prevent other pests from inhabiting. Wax production activities of wax worms stop before the harvest of ash can begin.
05
Lac worms
Lac worm is a tropical insect endemic to South Asia, distributed in Yunnan, Tibet, Guangdong, Guangxi, Fujian, Guizhou, Hunan, Taiwan and other provinces and regions in China.
Lac worms live on the host plant, sucking up plant sap, and the female worm secretes a pure natural resin through the gland - lac. It can be used as a coating for Chinese and Western medicine tablets, and can also clear heat and detoxify, and has high medicinal value. It is also an important chemical raw material, widely used in a variety of industries.
Farming tips: The life of the lac worm depends on the host plant to provide food and habitat. Select an ecological environment where climatic conditions can meet the growth and development requirements of lac worms, and require fertile land, good growth of host plants, well-developed gum worms, and stocking in places with few deaths. Such as the mountain range east-west direction or north high south low, the south side is open, shady slopes, winter has a long sunshine time, no frost or only light frost in winter, water and heat conditions are better. The different types of host plants and the quality of growth will also directly affect the survival of gumworms and the advantages and disadvantages of glue.
06
Tussah
A spitting insect , named after its fondness for eating tulip leaves.
Cocoon reeling silk, mainly used for weaving tulip silk, tulip silkworm is China's characteristic industry, tulip cocoon annual output has reached 70,000 tons.
The worm body is edible. Tulip silkworm 4-year-old larvae can cultivate Cordyceps sinensis; 5-instar larvae and pupae as a special insect food, can be fried, fried, fried, slippery and other cooking methods directly or as a filling to eat, Jilin Province Tonghua area has the habit of eating tulip silkworm 5-year-old larvae. In addition, tulip pupae powder can also replace fishmeal in poultry compound feed.
It can be used as a medicinal material, which has the effect of improving human immunity and anti-aging, promoting human protein synthesis, eliminating cholesterol in the body, lowering blood lipids and inhibiting the rise of blood sugar. Traditional medicine calls it a "god worm." At present, a variety of health care products have been developed on the market, the market share is very low, and the prospects for the development of drugs with therapeutic effects are broad.
It is recommended that you do not raise silkworms at home, not only do not have such a large field, but also can not afford to eat their leaves, so they are put on the mountain to raise. The silkworms are much larger than the silkworms and eat a large amount.
The above 6 kinds of insects are widely used in many fields, have farmers and friends farmed? Small bugs have a big role, interested friends may wish to take a closer look.
