Cricket knowledge (cricket knowledge, please let us know) 1. Please let us know your knowledge of cricket.

Crickets in hell are widely distributed, almost all over the country, and there are more provinces south of the Yellow River. It likes to inhabit hillsides, fields, stone piles and grasslands with slightly wet soil.

This insect usually begins to sing in August in summer, and it usually sings best in the wild at 20 degrees, and stops singing when the climate turns cold in the late period of 10. It occurs every year 1 generation, spawning in soil and overwintering with eggs.

When a male meets a female, his chirping can be changed into "chirp, chirp", and he makes a trembling chirp when mating. . "sound.

Male insects are aggressive. When two male insects meet, they first sing with their vertical wings to gain prestige, and then head to head, like pliers, open their jaws and bite each other and kick them around with their feet. They can often roll back and forth for 3-5 rounds. Then, the losing side escaped silently, and the winning side held its wings high and rang proudly, looking very proud.

Watching crickets fight is really a very interesting way to relax.

It likes to live in a slightly damp and dark place.

______________

Crickets are ORTHOPTERA insects and can sing and dance well. In ancient times, cricket fighting in autumn was very popular from celebrities to ordinary people.

Crickets are not completely abnormal. They only pass through eggs, larvae and adults, not pupae. Eggs overwinter in the soil and begin to hatch in spring and summer. Larvae live in groups in soil crevices and feed on microbial carcasses and plant roots. It began to metamorphose into an adult around beginning of autumn, reached the peak of metamorphosis around the summer heat, and lasted until the end of the autumnal equinox. Male and female crickets are easy to distinguish: the male is small, can sing, and has a pair of tail whiskers at the end of his abdomen, commonly known as "two tails"; This female insect is too big to sing. In addition to a pair of tail whiskers at the end of the abdomen, there is also an ovipositor tube in the middle, commonly known as "three tails".

Males generally have fixed caves, while females don't. Female crickets look for male insect caves according to their songs and become temporary spouses after entering the caves. Meet in the cave during the day. At night, the female worm breaks out of the hole and feeds and lays eggs. As a result, the male cricket became a "bachelor" at night and called the female cricket all night. The next day, at dawn, the female insect found her voice and went into the hole. It may be the original "wife" or a new partner. So crickets don't have a fixed spouse, and sometimes they may live in a nest with several females, but they don't quarrel. When the male insect courtships, his wings rub downward, making a gentle and pleasant sound of "playing the piano", which lasts for several minutes and half an hour, and the female insect will automatically climb onto the back of the male insect to mate. The so-called "three opposites" of crickets are "winning the song and losing the dumb", "the female is on the male's back" and "the tail is too strong".

The time to catch crickets, from beginning of autumn to the Millennium. As the old saying goes, "the generals will come out around the Millennium." Ten days after the Millennium, the outside temperature dropped, and the crickets' physique declined day by day, which had no capture value. During the day, the capture time is from noon to around 3 pm. Men and women live in the same room and can be found by playing the piano. Night hunting is from 8-9 pm to the early morning of the next day. Top-grade crickets usually sing around midnight, and often stop after a few calls. In early autumn, when catching insects at night, if the voice is cadence, intermittent, loud and hoarse, it is better to have a strong voice. And those who sing in a small and continuous voice are often small people. In the Mid-Autumn Festival, the selected voices are loud and powerful, and the hoarseness is usually the old bugs.

The habitat of crickets is closely related to the quality of insects. There are no good bugs around the house, garbage dump and barn. There are no strong players in the venues and vegetable gardens. Gua Tian and Doutian often have top grades, while barren graves, ancient temples, riverside trees and inaccessible places often get generals.

If you want crickets to "win the battle", seven points are planted and three points are raised. Cricket pots are generally divided into three types: straight bucket type, sky falling cover type and flower drum pier type. Choose a straight old basin in early autumn. As for wet places, it is good for summer. It's cold, choose a small flower drum pier basin, as for shelter from rain and cold. The first worm in the pot should be fed a piece of green vegetables to help cricket shed its dirty stomach. It's best to prepare some lotus leaf dew for crickets to drink. Do not use chlorine-containing tap water, at least use cold boiled water. People who are picky can prepare some Chinese herbal medicines such as Poria, Polygonum Multiflori Radix, Achyranthes bidentata, Dipsacus, Monkey Ginger, etc. and mix them with lotus leaf dew.

The cricket's food changes from time to time. Rotten rice is the staple food in early autumn. One tablet a day is enough. After the Mid-Autumn Festival, crickets began to lose their appetite, so they could be fed with raw winter melon pulp, cooked edamame and sweet apples. And when they lose their appetite further in late autumn and winter, sophisticated insect lovers can feed them with light shrimp meat, light crab meat, light eel meat and so on.

Pay attention to hygiene when raising crickets, and give them a bath every 3-5 days in summer. Put half a pot of dechlorinated tap water in the basin (one or two licorice roots can be put in), stir the water to make it rotate, then let the cricket float on the water for a while, remove the oil stains, and then pick it up immediately. The time must not be too long.

Generally, a male can breed 3-4 females (three tails), put them in at night and take them out the next morning. It can change the living habits of crickets and make them feel at home. Some fierce crickets may chase after three tails. At this time, they can prepare plum blossom three tails or fly three tails, which is the combination of tenon and mortise.

2. knowledge of crickets

Cricket is an ORTHOPTERA (Cricket Family) insect, which is famous for its sweet singing.

About 2400 species, 3? 50 mm (0. 12? 2 inches). The antenna is thin, the hind foot is suitable for jumping, and the abdomen has three hocks and two slender sensory appendages (tail whiskers).

The front wings are as hard as leather; The hind wings are membranous and used for flying. Males communicate with a row of teeth (about 50? 250) Rub against each other and make a sound.

The frequency of sound depends on the number of times of tapping teeth per second, ranging from the largest cricket species to nearly 1 0,500 cycles per second to the smallest cricket species. The rate of singing is directly related to the temperature, and increases with the increase of temperature.

The most common song is the courtship that attracts females; There are courtship sounds to induce females to mate, and there are also fighting sounds to drive away other males. Both men and women have sensitive hearing organs in the tibiotibial segment of the forefoot.

Most female insects lay eggs in soil or plant stems with slender ovipositors, which can often cause serious harm to plants. In the north, crickets are more mature than autumn to lay eggs, and nymphs hatch and molt in the next spring. 12 times and mature.

The average life span of an adult is 6? Eight weeks. Gryllus and Gryllinae's domestic crickets (formerly known as Gryllus Achetadomesticus) are stout, black or brown, and often make shallow holes; Feed on plants, animals, clothes or the like.

Field crickets, also known as black crickets, often live in fields or courtyards, and sometimes enter indoors. The head of domestic crickets is light with dark horizontal bands; Has been introduced from Europe to North America; Found in buildings and garbage dumps; Domestic crickets and field crickets are widely distributed and sing day and night.

It is sold as bait in the United States for biological experiments. The genus Oncomelania often appears in poems and texts.

For example, Dickens' The Good Earth. Nemobiinae is 12 mm long, has a series of high-profile vibrato, and lives in pastoral areas and forest areas.

There are three black lines in the abdomen of the striped needle cricket (Nemobiusvittatus). The swim bladder is white or green.

Wings are transparent; Eating aphids is beneficial, but it damages branches when laying eggs; Singing is a long vibrato. Snow-white tree cricket (Oecanthusfultoni) is commonly known as thermometer tree cricket, because the number of vibrato it gives out at 15 seconds plus 40 is about equal to the Fahrenheit temperature at that time.

Species inhabiting trees and shrubs call at night, while grass species call day and night. There are fewer species of liriominae, 3? 5 mm long, wingless, arched back, living in an ant nest.

A kind of wingless shrubbery cricket subfamily (Mogoplistinae), which is common under shrubs or rubble near the water in tropical sandy areas, and has a slender body, 5? 13 mm, wingless or small, covered with transparent scales, easy to grind off. Sparganinae (winged scrub crickets) 4? 9 mm long, sword-shaped ovipositor, living in the bushes by the pool.

The brown shrub cricket (Eneopterinae) is large, slender and light brown, which is common in trees or shrubs. In the east, people put male crickets in cages to listen to their calls; Cricket fighting has a history of hundreds of years in China.

Crickets play an important role in myths and superstitions. People think that the existence of crickets equals good luck and wisdom, and hurting crickets will bring misfortune.

A large brown fried cricket is sold in the market in Mandalay, Myanmar, and is often eaten by traveling monks. In English, many other insects are also called crickets, such as kitchen horses, Jerusalem crickets, moles and fleas.

Name of species [edit this paragraph] Cricket (Xishuai) (Gryllululus invertebrate, Insecta, Orthoptera, Cricket Family. A promoter, commonly known as cricket in northern China.

Morphological characteristics [edit this paragraph] Most crickets are small and medium-sized, and a few are large. Tan to dark brown.

The head is round, the chest is wide, and the filiform antenna is slender and easy to break. Chewing mouthparts.

Some jaws are developed, which is worse than biting a bucket. The forefoot and midfoot are similar and have the same length; Developed hind feet, good at jumping; The tail and beard are longer.

The lateral side of the auditory organ on the tibiofibular joint of the forefoot is larger than the medial side. Men like singing, fighting and killing each other.

There is a sounder on the front wing of the male insect, which consists of a scraper on the wing vein, a friction vein and a sounder. The front wing is lifted and rubbed left and right, thus vibrating the pronunciation mirror and making a tone.

The female body is larger, the needle-shaped or spear-shaped ovipositor is exposed, and the wings are small. Male crickets compete for food, consolidate territory and occupy females.

Distribution range [edit this paragraph] About 2,500 species are known in the world, and about 150 species are known in China, including 50 species in Taiwan Province Province. (In addition, the data here is debatable: there are more than 400 names of/kloc-0 in the world, and there are more than 30 in China. )

Several pests are dry crops. Living habits [Edit this paragraph] Crickets live in caves, often inhabiting the ground, under bricks and stones, in soil holes and in grass.

Go out at night. Omnivorous, eating all kinds of crops, saplings, vegetables and fruits.

Some behaviors of crickets can be induced by specific external factors. When fighting cricket, if you give the male cricket with fine and soft hair, it will prompt them to pounce on their opponents and fight hard; If you touch its tail hair, it will arouse its disgust. Kick it back with the tibiofibular joint of the hind foot to show resistance.

Crickets are withdrawn and generally live independently. They are never allowed to live with other crickets (males also live with another female when mating), so they can't tolerate each other. Once they meet, they will fight. Crickets are famous for their caution.

In the cricket family, male and female crickets did not achieve "a hundred years of good cooperation" through "free love". Which male cricket is brave and aggressive and defeats other members of the same sex, then it gains the possession of the female cricket, so polygamy is very common in the cricket family.

Of course, from the perspective of biological evolution, this is also natural selection, and the survival of the fittest is conducive to the healthy reproduction of the children and grandchildren of the cricket family. Besides, crickets are also famous for their singing. Different tones and frequencies can express different meanings. The loud and long-paced chirping of crickets at night is not only a warning to other sexes: this is my territory, don't invade it! At the same time, he appealed to the opposite sex: "I am here, come on!" When someone of the same sex intrudes unappreciative, it will sing with dignity and urgency to show a solemn warning.

If the "ultimatum" fails, then a murderous battle to seize territory and defend the leader will begin, and two crickets will open their teeth.

3. Information and habits of crickets

Information; A large family of ORTHOPTERA Grylloidea of Insecta. Cricket, also known as Kezhi, is a common name in northern China. About 2500 species are known in the world, and about 150 species are known in China, including 50 species in Taiwan Province province. Several pests are dry crops. Most crickets are small and medium-sized, and a few are large. Tan to dark brown. The head is round, the chest is wide and the tentacles are slender. Chewing mouthparts. Some jaws are developed, which is worse than biting a bucket. The forefoot and midfoot are similar and have the same length; Developed hind feet, good at jumping; The lateral side of the auditory organ on the tibiofibular joint of the forefoot is larger than the medial side. The ovipositor is exposed, needle-shaped or spear-shaped.

There is a sounder on the front wing of the male insect, which consists of a scraper on the wing vein, a friction vein and a sounder. The front wing is lifted and rubbed left and right, thus vibrating the pronunciation mirror and making a tone. Crickets dig holes and usually live on the ground, under bricks and stones, in soil holes and in grass. Go out at night. Omnivorous, eating all kinds of crops, saplings, vegetables and fruits. Some behaviors of crickets can be induced by specific external factors. When fighting cricket, if you give the male cricket with fine and soft hair, it will prompt them to pounce on their opponents and fight hard; If you touch its tail hair, it will arouse its disgust. Kick it back with the tibiofibular joint of the hind foot to show resistance.

Common crickets (such as Beijing oil gourd) have one generation a year and overwinter in the soil with eggs. Egg production per unit area is produced in fields with many weeds and plenty of sunshine, graves and soil beside haystacks. The male built a cave and lived with the female. I like living in a cool, relaxed and humid environment. When insect populations are too dense, they tend to kill each other. In Guangxi, the generation of peanut cricket is 1. The nymph overwinters in the soil cave and is unearthed in March-April of the following year, which is harmful to peanut seedlings. At the beginning of June, it appeared as an adult and continued to do harm. 1 1 mid-to-late October, nymphs began to overwinter. The caves of adults and nymphs are as deep as 0.6 meters or even deeper. The newly built cave is very simple, with only one escape hole. Before laying eggs, make 3~5 extra holes for eggs, and go out to look for tender stems, leaves and seeds of peanuts, and transport them back to the holes for storage for newly hatched nymphs to eat. The newly hatched nymphs live in groups, so they will go out for food and dig their own holes in a few days.

Crickets are important agricultural pests in Northeast China, North China, Lower Yangtze River and South China. They harm the roots, stems, leaves, fruits and seeds of various crops, especially seedlings. In the south, peanut mole cricket destroyed peanut seedlings 10%~30%, and also harmed corn, jute, tobacco, cotton, soybean and cassava, which often caused seedling shortage and affected harvest. Habit; It often lives on the ground, under bricks and stones, in soil holes and in grass. Go out at night. Omnivorous, eating all kinds of crops, saplings, vegetables and fruits.

Please talk about the life habits of crickets, focusing on what they eat.

1. The purpose of raising crickets artificially is to obtain top-grade crickets that are big and aggressive, so it is very important to choose the females and males who stay.

The requirements for selecting male insects should be general insects, and generally avoid using defeated crickets to keep seeds. The three-tailed female should be larger, and the eggs produced are also larger, and the larvae hatched in the future are also larger.

Three flavors will be used in early autumn. At this time, the three flavors have just emerged, and the number of mating in the wild is not much. Some of them are primitive women. If caught in the middle and late autumn, the three tails have mated many times in the wild, and the seeds in the abdomen have been mixed, which can not meet the requirements of cultivating improved varieties.

In early autumn, we should also choose varieties with big head, long face, long neck, fat body, long wings, white claws, fine meat and unclear color for breeding. The following points should be paid attention to when preserving the ideal male and female species: ① It is best to choose the same color insects for the paired male and female crickets.

For example, the color of the head, the color of the bucket silk and the color of the insect body should be the same or similar, so that the hatched offspring are pure in color and easy to select and fix. ② After mating, the male cricket must be reared before and after the fight, and it is best to breed formally after the autumnal equinox, when cricket is in full bloom.

The offspring of the eggs laid after mating are also the strongest and the species is pure. (3) It is best for male and female crickets to mate (knot the bell) for 3-5 times to ensure that the eggs laid are completely fertilized.

Second, lay eggs and save the three tails after the bell rings. Be sure to find a place to lay eggs. Therefore, the tools for laying eggs must be ready before ringing the bell.

Take a 30 cm clay pot, wash it and expose it to the sun for disinfection; Take a proper amount of yellow sand, wash it, fry it on the stove and disinfect it; Take a proper amount of garden soil, mash it and dry it; Sand and soil should be mixed with appropriate amount of water according to 1: 5. It is advisable to see dry soil below, not too wet. Spread into a soil basin about 7~8 cm thick.

A three-tailed breeder who can lay eggs will lay eggs in the soil. You can also roll toilet paper or napkin with good water absorption into a paper strip with a diameter as thick as two coins, and drip water around the basin to make the paper wet.

So Sanwei will also lay eggs in the paper roll. A female cricket lays about 200 eggs in a lifetime, and about one third of the nymphs hatched are male and the rest are female.

However, nymphs cannot be identified until they are over four years old, which increases the workload of artificially incubating crickets. Gently take out the eggs laid by the three tails and observe them carefully with a magnifying glass, and you can find that the shapes of the eggs are slightly different.

The shape of eggs is pointed at both ends, and the number is small; The other kind of egg is round at both ends, slightly shorter and thicker than the previous kind of egg, and the number is far more than that of two slightly pointed eggs. Practice has proved that most of the eggs with two pointed heads are male, and the short and thick eggs with two slightly pointed heads are female.

Before hatching, eggs are selected from the soil and selected as needed. Whether you choose a female egg or a male egg, you must choose an egg with full particles, uniform color and large particles, which is about 2 mm long. In the natural environment, nymphs will hatch in the middle and late May or early June.

However, the artificially collected eggs are placed indoors, which is higher than the outdoor temperature, so the incubation time of eggs is a little earlier than that of outdoor. If you don't want the eggs to hatch prematurely, you can move the containers for eggs outdoors and put them in a cool and humid place to keep the temperature of the eggs consistent with the natural environment, so that the nymph will not be unearthed in advance.

However, it should be noted that the soil with eggs should be kept at a certain temperature, and the soil should not be too dry, otherwise the eggs will easily die. Of course, the soil should not be too wet, and it is better to be wet and impermeable.

3. Before hatching, select the eggs as required and put them into the container. There should be mud at the bottom of the container.

After the eggs are put in, cover them with a thin layer of soil (the soil must be crushed to dry and sprinkled with a little water). Sprinkle water slightly every 3~5 days to keep the soil moist and ensure the smooth hatching of eggs.

The water to be poured should be clean river water or rainwater. If tap water is used, it must be left for several days before use.

1, incubation temperature Cricket eggs begin to develop and hatch at 25℃~30℃. The temperature of overwintering eggs will reach 25℃~30℃ in April and May.

It usually takes about 20~25 days to hatch from eggs to nymphs. Under the premise of maintaining a certain humidity, nymphs will break out of their shells as long as they are given the appropriate temperature for hatching.

Therefore, in artificial reproduction, as long as the conditions for incubating eggs are created, eggs hatch in almost any season. 2. After the nymph hatches in the farm, it is very important to have a good living environment, which is very important for the growth and development of nymph.

Therefore, a few days before the nymph hatches out of its shell, it is necessary to choose an ideal artificial farm and start preparations. The soil on the farm must be very good. First, the soil is loose and fertile. The second is that it is not polluted by harmful substances.

The farm is located in Gao Shuang, with good drainage and no water accumulation. The environment around the farm is good, and there is no chemical plant, especially the waste gas and sewage containing harmful substances. After selecting the site, it is best to turn over the land once or twice to achieve the purpose of loosening the soil and killing insects.

Then add some organic fertilizer and green feed to make the soil fertile and rich in humus. Then plant some melons, beans and hemp plants without peculiar smell, so that the sunlight cannot directly reach the ground of the farm (it should be noted that the farm should never choose a cool place where the sunlight cannot reach).

Grow and develop in such an ideal place. If you put some old tiles and bricks on the roof of the site, nymphs will have more hiding places.

On the one hand, it further provides a good living environment for crickets, and at the same time it can improve the stocking density. 3. Nymphs should be fed with artificial feed regularly during their growth and development.

The processing of artificial feed is to use the new indica rice of that year, grind it without elutriation, add a proper amount of cooked soybean powder (about one-fifth of rice powder), add some bone powder, blood powder, liver powder and fish powder rich in calcium and phosphorus, mix well, put it in a container, and then mix it with water and cook it before feeding. You can also catch small insects such as locusts and grasshoppers, kill them, dry them in the sun, grind them, and mix them with vegetables, fruits and other foods rich in vitamins and cellulose.

Beans should not be eaten raw, but other plants should be eaten raw to ensure that the original nutrients of plants are not lost. Feeding should be fixed to facilitate daily cleaning, but more should be put. You can feed it twice a day, once in the morning, once in the evening, and once in the evening is the most important.

Crickets like light and belong to nocturnal insects. Usually hide in caves during the day and come out for food at night. When breeding, I found that nymphs like to eat very much.

5. Information about crickets

Crickets are distributed in Guangdong, Guangxi, Fujian, Hainan, Guizhou, Yunnan and Taiwan Province provinces, as well as in Pakistan, Malaysia, Vietnam and other countries.

Crickets usually inhabit sandy land with loose soil and sparse vegetation, or fields, orchards and nurseries of peanuts, beans and other crops. Digging deep holes in the soil often makes a living, and the main hole can reach 80~ 100 cm deep.

This insect harms the roots, stems and young leaves of plants. It eats pine, fir, camphor, oak and other trees, as well as wheat, rice, peanuts, beans and other crops and vegetables. This is a famous pest. Most females and males live in caves, and females lay eggs in caves.

Crickets lie down during the day and come out at night. At night, the male insects sing in the hole to lure the female insects out of the hole to mate. Its hole is a round hole the thickness of a finger, and the hole is covered with loose soil, which is not easy to be found.

Its voice is rich and loud, and it is "sentence by sentence". Its rhythm is fast and continuous, often lasting 20~30 minutes, which sounds like cicadas. This kind of insect is fierce and has the habit of killing each other. Except for newly hatched nymphs, its adults and nymphs dig their own caves and live together only when mating.

They often feed at the mouth of the cave, and often cut off twigs and drag them back to the cave to eat and store them. Crickets come out of their holes every few days 1 time, and like hot sunny days and warm climate. They go out of the cave after dark, and they can't stay in the cave when it is windy and rainy.

6. Life habits and characteristics of crickets

Life habits of cricket: Cricket lives in caves, often inhabiting the ground, under bricks and stones, in earth holes and in grass. Go out at night. Omnivorous, eating all kinds of crops, saplings, vegetables and fruits. Some behaviors of crickets can be induced by specific external factors.

Crickets are withdrawn and generally live independently. They are never allowed to live with other crickets (males also live with another female when mating), so they can't tolerate each other. Once they meet, they will fight. A male cricket can live with many female crickets.

Crickets are characterized by round head, broad chest and slender antennae. Chewing mouthparts. Some jaws are developed, which is worse than biting a bucket.

Extended data

Economic significance of crickets: Crickets are important agricultural pests in Northeast China, North China, Lower Yangtze River and South China. They harm the roots, stems, leaves, fruits and seeds of various crops, especially seedlings.

In the south, peanut stinkbug damages peanut seedlings 10~30%. They also harm corn, jute, tobacco, cotton, soybeans and cassava, often leading to a shortage of seedlings and affecting the harvest.
