Beneficial insects, in a broad sense, as long as they are beneficial insects to humans, can be called beneficial insects, whether in agriculture, economy, food, medicine and other aspects, as long as they are beneficial to humans, they are called beneficial insects. Beneficial insects, referred to as beneficial insects. In primary school textbooks, insects that are beneficial to agriculture, including insects that help plant pollination and eliminate pests, are generally referred to. Usually, there are many beneficial insects living around us, and the following love animals will introduce the common beneficial insects around us.
Bees: Hymenoptera, Beeidae. Bees live in groups, and there are three types of bees in the bee colony: queen bee, worker bee and male bee.

Legend has it that as early as 3,000 years ago, the Yellow Emperor's wife, Changzu, began to "raise silkworms for silk". Silkworm insects and pupae can be eaten and have therapeutic effects. Sun Simiao's "Preparation for Emergencies" contains: "Silkworm pupae taste salty and warm, the main benefit of essence"; "Dietary Therapy Materia Medica" contains: "Silkworm pupae are rich in nutrients, and eating is very beneficial to people". Modern medicine has confirmed that silkworm pupae oil and silkworm pupa protein have hypoglycemic, immune enhancement, anti-aging and other effects. Silkworms are also the source of the traditional Chinese medicine "zombie silkworm".
Silkworm larvae:
Adult silkworms:
Earthworms like to live in moist soil and emerge day and night, but earthworms are beneficial insects, it swallows a lot of soil every day, absorbs the saprophylls and small organisms in the soil, and then excretes the soil, making the soil loose and fertile, which is very conducive to the growth of crops. So the peasant uncles are willing to have more earthworms in the land. (Note that earthworms are not insects, but are beneficial to humans, so listed.) ）

Grasshoppers, belonging to the Pulsoptera family, some species of the grasshopper family eat only about 150 aphids in their lifetime, while others can eat 100 aphids a week. As a result, in some countries, millions of such insects are raised for biological pest control in agriculture and horticulture.
Lac worm is a world-famous resource insect. The secretion of female lac worms is an important source of industrial raw material lac, and the largest production area of lac in China is in Yunnan Province. China's annual output of lac hundreds of thousands of kilograms, in addition to meeting the needs of the domestic market, but also part of the export.

Native to Mexico, magenta is a tiny class of mesmeria that parasitize the cactus plant. Before the chemical dye was available, the natives of Mexico discovered the magenta and used it as a red dye. In 1518 Spain introduced it to Europe and gradually became an industrial product. The years 1831-1874 were the flourishing years of insect magenta, with production peaking. With the progress of science, the chemical aniline dye industry is developing day by day, and the insect magenta dye is gradually declining and is replaced by chemical dyes. However, insect magenta is a dye belonging to biological products, and it still has unique advantages in food, beverages, biomedicine, cosmetics and other colors, because it is safe for the human body, which is incomparable to chemical dyes.
Cochineal, an insect of the beadworm family, is an animal dye extracted from its red body fluids, rouge, which is the best raw material for dyeing food, biology and cosmetics.

White ash has stable physical and chemical properties, with closed, moisture-proof, rust-proof, durable, light, muscle, hemostasis and pain relief, deficiency, tendon and bone, etc., is an important raw material in military, light industry, chemical, manual and pharmaceutical production. Such as anti-corrosion polishing of metal products, moisture-proof, anti-rust and lubrication of precision instrument machinery. Due to its high melting point, the model and teaching aids produced do not soften or deform under the high temperature of summer. The textile industry is used for glazing agents, filling and glazing agents in the paper industry, anti-corrosion of capacitors, automotive wax, floor wax, raw materials for cosmetics, polishing of precious furniture, etc., especially the demand for white wax in the military, aerospace, scientific research and other departments is increasingly surging.
Pentapler aphids belong to the order Homoptera, The Family Aphididae. Aphids do not have a abdominal canal, or the abdominal canal degenerates, and the mouth organ degenerates. Generally, there are developed wax glands, often secreting white cotton-like substances, so it is often called cotton aphids or cotton worms.

For example, "Ren Zhai Zhi Zhi Fang" said, the treatment of carbuncles is swollen and hard, with the processed insect body into a powder and garlic mash paste, use a little paste, pus out of the medicine. "On the Great Theory of Medical Prescriptions" said that 21 cantharids and a spoonful of glutinous rice were fried in three times, and after frying, the spotted scorpions were removed, and the rice was used as powder, and the cold water on an empty stomach was used to treat rabid dog bites. Another example is the "Dictionary of Chinese Medicine" fang, with an egg to cut a small hole, put in the processed head, feet, wings of one to three stings, baked after the removal of the spotted scorpion, eat an egg every day, cure liver cancer, stomach cancer. However, when using cantharid drugs, whether used externally or internally, they should follow the doctor's instructions and must not be used on their own initiative, because the toxicity of cantharids is too great.

In fact, there are many beneficial insects in life, such as predatory aphids, aphid-eating flies, insectivorous flies, insectivorous tsubaki elephants, insectivorous thrips, insectivorous beetles, insectivorous spiders, grubs, corianders, red-eyed bees and so on.
However, not all beneficial insects are necessarily harmless, and there are many insects that are beneficial to humans, and they are also harmful, but the benefits outweigh the harms. For example, the golden cicada can be edible, and the taste is delicious, rich in nutrients, the skin of the golden cicada can also be used medicinally, but the golden cicada will also suck the sap of the plant, endangering the growth of the plant; the earth dog (caddisflies) can be used as a medicinal use, but it is also a pest in the crop field, harming the crops. Therefore, beneficial insects are not necessarily completely beneficial, and pests can sometimes play a big role in humans.
