Also known as promoting weaving, commonly known as crickets, night insects (because it chirps at night), general insects, autumn insects, cockfights, weaving, weaving, tending to weave, ground trumpets, stove chickens, Sun Wang, soil stinging, "monk" is the name of the cricket before the cricket gives birth to wings. According to research, crickets are an ancient insect that is at least 100 million years old and is still the object of fighting in ancient and modern times.

There are 595 genera (including 17 fossil genera) and about 4649 species (subspecies) (including 50 fossil species) in 22 subfamilies, 55 families, and 595 genera (including 17 fossil genera) known worldwide. Insects of this family are larger than 3 mm long and lack scales; antennae filiform, longer than the body; 3 tarsal segments, walking feet on the forefoot, tympanosis often with eardrum hearing, and jumping foot on the hind foot; Most species of males have vocal structures on their forewings; Females have well-developed oviposition lobes that are knife-shaped, spear-shaped, or long-plated.

Most of the crickets are small and medium-sized, and a few are large. Cricket species are larger than 3 mm in length; The body color varies greatly, mostly yellow-brown to black-brown, or green, yellow, etc.; There are fewer homogeneous body colors, and most of them are variegated. The body does not have scales.

The mouth type is either the lower mouth type or the front mouth type. antennae filiform, much longer than body length; The antennal stalks are mostly rounded shield-shaped, narrower than or equal to the frontal process; A few taxa are elongated shield-shaped, larger, wider than the frontal process. The compound eye is larger, generally 1 4 1 2 of the head length;There are generally 3 pieces in each eye, arranged in an inverted triangle or line; The middle monocular is located on the dorsal side of the head, on the face, or at the apex of the frontal process.

Yellowish-brown to black-brown.

The head is round, the chest is broad, and the antennae are slender. Chewing mouthparts. Some have large jaws that are well developed and stronger than bites. 3 pairs of tarsal joints of each foot, with similar forefoot and midfoot and same length; The hind feet are well developed and are good at jumping; Auditory apparatus on the tibial joints of the forefoot, lateral to greater medial.

The oviposis is exposed, needle-shaped or spear-shaped, and consists of 2 pairs of tube flaps. Both male and female have 1 pair of tail hairs on the ventral ends. Males have 1 pair of short rod-shaped ventral spines at the ventral end.

Females are larger, with needle- or spear-like ovipositor tubes bare and small wings. Male insects have articulators on their forewings, which consist of scrapings on the wing veins, rubbing veins, and articulatory mirrors. The forewings are raised and rubbed from side to side, thus vibrating the articulation mirror and producing tones.

The body color is mostly dark brown, the body is mostly barrel-shaped, with thick hind legs, and filamentous antennae that are longer than the body. There are two long tail filaments at the end of the abdomen, and if it is a female, there is also an oviposition tube longer than the tail filament, and there is another way to distinguish between male and female, the male with obvious concave and convex patterns on the wings, and the female with straight wing lines. Most peculiarly, his hearing device is on the forefoot segment.

Crickets are also known as "promoting weaving", "tending to weaving", "chanting", and "crickets". Insecta, Orthoptera, Crickets. The antennae are longer than the body.

The female is fluid and the ovipositor tube is bare. Males are vocal, aggressive. There are many species, the most common is the Chinese cricket, which is about 20 mm long.

A generation of births. Pronounced with wings rubbing. The dry worm body is used as medicine, the sex is warm, the taste is old and pungent, toxic, the function is diuretic, the main benefit is edema, and the urine is blocked.

There are oil hyacinths, large coffin crickets and so on in the same family. Because they are all active underground, they eat the stems and leaves, seeds and roots of plants, which are all agricultural pests.

<> crickets have a more mixed diet, they can eat vegetables, fruits, and high-protein meats, such as small fish and shrimp, small loaches, etc., and can even eat fish feed. However, if you are domestic, you are usually fed vegetable leaves, grass, and a paste mixed with protein powder, glucose, and honey. Be careful not to give the cricket food that is too watery, as this can easily cause diarrhea.

Crickets do not like light, and the bright place is not suitable for raising them, so the breeding box should be placed in a relatively dim location.

1. What do crickets eat

1. The eating habits of the cricket are very mixed, it can eat vegetables, fruits, and high-protein meat, such as small fish and shrimp, small loaches, etc., and even fish feed. If you choose to raise them domestically, you can usually alternately feed vegetable leaves, grass and a paste mixed with protein powder, glucose, and honey.

2. Note that you must not give the cricket food with too much water, otherwise it will easily cause diarrhea. Once this diarrhea problem occurs, it can easily cause widespread death.

3. Crickets don't like light, and the bright place is not suitable for breeding them, so the breeding box must be placed in a dim position when breeding, and the temperature is controlled at about 20-25 °C, and the crickets will hibernate when it is lower than 10 °C.

Second, whether crickets are beneficial insects or pests

1. Crickets are pests. Crickets are important agricultural pests in Northeast China, North China, the lower reaches of the Yangtze River and South China, they will destroy the roots, stems, leaves, fruits and seeds of various crops, and the damage to seedlings is particularly serious. In the south, 11-30% of peanut seedlings are damaged by crickets, and they can also damage maize, jute, tobacco, cotton, soybeans and cassava, causing seedling shortages and affecting harvests.

2. Crickets living in the wild generally feed on young shoots, young leaves and roots, in addition to eating a variety of fresh vegetables and fruits, the breeder can also choose some other foods, and make nutritious meals in proportion. Regular and quantitative feeding should be carried out every day, so that the crickets can grow healthier.

3. The character of crickets is more withdrawn, most of them live independently, and will not live with other crickets, they only live with female crickets during the breeding and mating period, otherwise they will not be compatible with each other. If two crickets touch each other, they will bite and fight directly, so there is a folk activity of fighting crickets.

Crickets are not beneficial insects. In agriculture, people take crickets as pests, which are important agricultural pests in Northeast China, North China, the lower reaches of the Yangtze River and South China, destroying the roots, stems, leaves, fruits and seeds of various crops, mainly harming corn, jute, tobacco, cotton, soybeans and cassava, etc., the damage to seedlings is particularly serious, often causing a lack of seedlings and affecting the harvest. <
