What is the secret of insects?

1. What is an insect? Insects belong to Insecta, the phylum Arthropoda, in the animal kingdom. Insects are divided into three parts: chest and abdomen. The head has 1 pair of antennae, 1 pair of compound eyes, 1-3 single eyes and 3 pairs of mouthparts. The chest has 2 pairs of wings and 3 pairs of feet; There are tail whiskers and reproductive limbs or ovipositors in the abdomen.

2. What changes have taken place in the life of insects? Completely metamorphosed insects go through four stages: egg, larva, pupa and adult; Incomplete metamorphosis insects go through three stages: egg, nymph and adult.

3. How big is the insect family? Insecta is divided into 33 orders, and each order is divided into many families, many genera under families and many species and subspecies under families. There are more than 654.38+0000000 species of insects known in the world. It is estimated that there are more than 654.38+000000 species of insects on the earth. There are more than 500,000 ants in 654.38+0 bee colony, more than 654.38+000000 ants in the world, millions of termites in 654.38+0 bee colony and 80,000 locusts in 654.38+0 bee colony.

4. Where do insects live? There are no insects anywhere on the earth, such as mountains, plains, lakes, oceans, deserts, polar regions covered with ice and snow all year round, and the extremely hot equator. From the sky to the soil, from the land to the water, from the wild to the living room, from animal bodies to human bodies, from dead bodies to living bodies, from plants to garbage, there are hiding places for insects everywhere.

5. What do insects eat? Insects eat everything that people can eat, but also things that people can't eat, such as living animals and plants, dead or rotting animal carcasses, animal feces or excreta, various crops and their products planted by human beings, human or animal blood, dried wood, dried animal bones and so on. It can be said that insect food is everywhere.

6. What do insects wear? Most insects live naked, but there are also many insects that spin cocoons or wrap themselves in leaves. For example, the female moth spends her whole life hiding in silk bags like coconut shells for food and babies. The skin of this insect is called the body wall, also called the exoskeleton. The body wall is divided into three layers, which are basement membrane, skin cell layer and epidermis layer from inside to outside. It protects the body of insects. Insects often shed their old epidermis and put on new ones in their lifetime. This phenomenon is called-peeling-,and the exfoliated skin is called-molting-. It can be seen that the upper epidermis and molting of insects are insect clothes.

7. How do insects walk? All mature insects have three pairs of pectoral feet, which can be used for walking. And immature insects, some have feet, some have no feet, and some have many pairs of abdominal feet besides chest feet. All insects with feet can walk with their feet, while insects without feet can move forward through the expansion and contraction of abdominal internode membrane to achieve the purpose of walking. In addition, most adult insects have two pairs of wings and can fly freely in the air like birds. A butterfly can fly 5000 kilometers continuously by plane. Insects can also spread to every corner of the earth through water, wind and various means of transportation.

8. Which insects are the most annoying? Blood-sucking mosquitoes, bedbugs, flies and lice; Flies, houseflies and cockroaches that spread diseases; There are wasps (wasps), bumblebees, burning insects (caterpillars), pine caterpillars, tea caterpillars and so on. , are very fierce and stinging. There are also various pests that endanger human and animal health, destroy crop yield and harvest, and destroy the normal growth of forests and green plants.

9. Which insects do you like best? Dancers of nature-picturesque butterflies; Dragons in the air-dragonflies; Folk Song Society-Guo Guo, Weaver Girl (owl) and Cicada (cicada); A brave and invincible general-cricket; Unique big man-unicorn fairy (a kind of scarab); Fluorescent pastoral starlight-fireflies and so on; There are also many unknown field guards guarding crops-natural enemy insects day and night.

10. Which insects are the precious wealth of human beings? Industrial raw materials insects-such as wax insects, silkworms, etc. ; Medicinal insect-Cordyceps bat moth (producing Cordyceps sinensis); Exotic insects; All kinds of ants; Aspongopus, etc. Edible insects-such as locusts, silkworm chrysalis, honey, ants, termites, fly maggots, Tenebrio molitor, etc. -Ornamental insects-such as butterflies, crickets, singing insects, unicorns, etc. Pollination insects-bees, wasps, bees, flies, moths and butterflies, beetles, bedbugs, etc.; Natural enemies insects-such as mantis, wasp, dragonfly, lacewing, ladybug, walker, etc. Clean insects-such as buried insects, dung beetles, dung beetles, etc. Insects used in bionics research-such as dragonflies, fruit flies, bees, ants, bloodsucking midges, fireflies and so on.
